Connecting 2 WAN clouds on the same IP address range.

Hello, I have a problem connecting my office to two third party companies.
I have two Cisco 1700 series WAN links to my office from these companies, Both routers are fully managed by their respective companies, both use static routing, and both are using the 10.0.0.0/8 IP address range.
The first company assigned my office the address range 10.212.1.0/24.
The second company assigned my office the address range 10.215.1.0/24.
My office can be set to any IP address range.
My questions are:
Is it possible to have a connection from my office to both networks at the same time? If so how?
Do I require these companies to provide me with their static routing information? or can I use routing protocols?
Do I need to perform NAT?
Can I use a PIX 515e firewall with three interfaces?
Sample configuration would be greatly appreciated

It's possible to have connections to your offices at the same time with the usage of subinterfaces.The usage of static and dynamic protocols depends totally based on the size of the topology of your network.If it's a very very small network static routing will do. Performing a nat totally depends upon ypur decision whether to use a public ip or not.If required you can use a pix firewall

Multiple sites ASA's connected to Cable modems with same DHCP address

I have several locations with an ASA 5505 installed behind a cable modem. The cable modem is issuing DHCP for the same network address range in these locations. I have the outside interface obtaining DHCP from the cable moden network and the asa's are receiving the same outside address. I have the remotes set to use EZVPN to create the VPN tunnel back to the head end ASA 5540. I am seeing constant rekeying for phase 2 for those remote sites. is there any thing I can do short of assigning each asa a unique outside address?

Dave
The Linksys doing NAT is the reason why the ASA sees all the traffic as having source address as 192.168.2.1. The only way for the ASA to see the original 192.168.1.x address is to change the Linksys to not do NAT.
One thing that I notice is that there is not a route statement in what you posted for the 192.168.1.0 network. It is not clear whether the route does exist and you did not post it or whether the route does not exist. But if it does not exist it would certainly be a reason why you lose Internet connectivity when you change the Linksys to not perform NAT. (the ASA would have no knowledge of how to forward to the network and would drop all the traffic). Try adding the route to the ASA and changing the Linksys to not perform NAT and let us know if it works.

Add the same email address twice

Hi there,
I am in the process of moving my email address from gmail to a server.
I am keeping my gmail one going for awhile to reference old emails so ideally I would like to have my email address connected to google and the same email address added connect to my server. So I will receive new emails from my new server and the same email address to see my old emails on google.
Is it possible to add the same email account twice but connect to different servers?
Any information would be greatly appreciated.
Many Thanks
Jamie

Isn't your original email address used for an icloud account, or is it an old one from mobileme? If the latter, and the account was not upgraded to icloud, then no, you can't use it. When you create a new icloud account, you specify an ID (which is used as the email address). It must be an unused ID.

LAN and WAN share the same MAC address -- could this be a security issue?

When I bought the AEBS(n), I was a bit surprised to see only one ethernet MAC address listed (on bottom of unit, or was it in config utility?), in addition to wireless MAC. My main router has two ethernet MACs.
So last nite, I investigated. I confirmed my suspicion that both the WAN port and the LAN ports share the same MAC address! My setup has the AEBS WAN port plugged into my home LAN's main router, and a Linux machine plugged into a LAN port of the AEBS.

10.0.1.1 on the LAN side of AEBS and 192.168.1.21 on the WAN side of the AEBS both use the same MAC address, 00:16:CB:C4:30:A6.
I tried to provoke some leakage between the two sides (for example with broadcast packets), but haven't been able to do it so yet. Perhaps the switch in front of the eth MAC has enough smarts to keep the two subnets separate? Still it sort of worries me, if I used the AEBS as my only router, that both WAN and LAN go thru the same ethernet MAC (same h/w). I browsed here but found no discussion on this.
Comments anyone?

.... This is why there are separate MAC addresses
for ethernet and wireless, they are physically
different networks. In the case of the WAN/LAN, both
are ethernet-type networks but are physically
distinct (this is the purpose of a router like the
AEBS), so having the same MAC address on both sides
won't cause any sort of collision nor should it be
possible to leak across networks. MAC addresses can't
be used for routing beyond the physical network.
If it is indeed two different NICs sharing a single MAC, then indeed it is not an issue as you would never want to connect these two NICs together. But is it really two NICs?
My worry is that these two subnets are on the same physical network, with some magic going on to keep them separate anyway. Do we have some picture of AEBS internals? Maybe that would answer the question...

HT5624 My husband and I share an Itunes account so use the same email address and password. Our iphones are now connected and we get each other's messages and share each other's contacts. How can we stop this happening?

My husband and I share an Itunes account so use the same email address and password. Our iphones are now connected and we get each other's messages and share each other's contacts. How can we stop this happening?

A couple of different approached:
Create a second AppleID for one of you that includes the email address and phone number you wish to use for messaging, but do not apply it to the iTunes and app store (just keep the current one). My wife and I do this and it works quite well. Also allows for easier syncing of Contacts , notes etc. using icloud if you wish to do that.
Add additional emails/phone numbers to the existing account and change the Send/Receive settings for Messages. this will not fix the Contcts isues for you however.

Can I use the same email address for multiple seats in Creative Cloud for Teams?

Can I use the same email address for multiple seats in Creative Cloud for Teams?

No. http://www.adobe.com/products/creativecloud/faq.html
Can I buy more than one membership to an individual offering of Creative Cloud?
No, Adobe has moved to identity-based licensing with a technology that will not support multiple same-product licenses, so you can buy only one membership per Adobe ID. If you need two Creative Cloud memberships, you will need to purchase each with a unique Adobe ID. You can also purchase a Creative Cloud for teams membership, which allows you to purchase and manage multiple seats under one account.

"another device is using the same ip address.." - iOS devices won't connect to AEBS wifi.

I've got a Motorola modem/gateway - 3360 from WalMart. I have the AEBS working in bridge mode connecting my iMac & Printer fine, but my iOS devices won't connect.
While troubleshooting & trying all types of settings, I was able to get EITHER the iMac or the iOS devices connected to internet, but not both at same time.
Then I noticed I am getting "another device is using the same ip address.." message.
I have changed the AEBS ip address & had been able to get either the iMac or iOS devices working depending on which ip address I use.
BUT now, all my iOS devices dont connect to the internet regardless of the ip address of the AEBS.
All my iOS devices see the network, and accept the network password, but they do not connect to internet, circle just keeps spinning...
Any assistance is GREATLY appreciated.
Thanks for any assistance,
Dave

It looks like may have to go back to square one and delete my network & set it up from scratch if I don't figure it out.
If you do go this route, I would like to make a suggestion for your consideration, and that is to assign static IP addresses to devices that are "permanent" on your network or ones you want to make sure can be reachable at all times. These (again) would be servers, routers, wireless access points, network printers/scanners, NAS devices, etc.
I would recommend the following IP addressing scheme as a baseline and you are certainly free to deviate in any way you see fit to meet your networking requirements:
Reduce the number of IP handed out by DHCP. By default, most routers will provide 100-200 private IP addresses within their DHCP leasing scope. The AirPort, by default, assigns 10.0.1.2 thru 10.0.1.200 via DHCP. Your Motorola may assign 192.168.0.2 thru 192.168.0.150. Either way, I would reduce this to no more than fifty (50) total which should provide you with plenty of addresses even if you are hosting gaming convention at your home.
I use the following IP address scheme for the "permanent" network clients:
Network Printers: 10.0.1.200 - 209
NAS Devices: 10.0.1.210 - 219
Wireless Access Points or routers reconfigured as bridges: 10.0.1.220 - 229
Servers: 10.0.1.230 - 239
With the "permanent" devices pre-assigned with static Private IP address that are outside of the DHCP range, you shouldn't ever get an IP address conflict again.

Macbook Air has the same IP address as another device on my network

I recently connected airport extreme to my network, and now I cannot connect to the Intenet from my MacBook Air. The error message I get is that another device on the network is using the same IP address (192.168.1.64) I also have a mcbook pro, which is working fine, and whose IP address is 108.66.128.91, so I don't know which device has the duplicate IP address.
Furthemore, I can't connect to the new WiFi signal from my iPhone. What do I need to do to fix these errors?

I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
Power-up your computer(s).
If the above steps do not solve the problem, start over with step 1 above, but then perform the next steps between steps 1 & 2. above.
Disconnect the AirPort base station from the Internet broadband modem.
While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
Continue with step 2 in the first set of steps.
In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.

How can i use Mail on 2 macs with the same mail address?

Hi,
I have two Macs, connected through WLAN. From each Mac I can use Mail (sending and receiving) with the same mail address. This worked well; on each Mac I have separate files storing the mails (input, sent, trash, …).
Some days ago I had to change the provider. (Perhaps this may be the reason for my problem?) Now both mail systems are connected - in the way that if I put on Mac *1 a mail into the trash it is automatically thrown into the trash on Mac *2.
What is to be done to separate the two systems (i. e. make them independent of each other)?
Hans

It looks like you are using a IMAP mail account, a protocol used by most email providers nowadays. Read -> http://en.wikipedia.org/wiki/Internet_Message_Access_Protocol
The main feature of IMAP is the sync of all the changes you do on your mail account. If you want to keep your mails on one Mac, have a look at this site -> http://kb.mit.edu/confluence/pages/viewpage.action?pageId=3908294

Someone has the same email address as me!

I know this shouldn't be possible but it's happening! I have an apple email address [email protected] and as I understand it that automatically gives me [email protected] too. I don't ever use the icloud domain but I have tested it and if I send an email to [email protected] I receive the email.
A month or so ago I received a load of emails, receipt etc. for a purchase that had been made on a website, registered to the email address [email protected] I presumed someone must have entered the wrong email address and so contacted the website owner and said I'd been sent these emails in error. They contacted the person and came back to me saying that they had said the email address was correct. I asked them to contact them again (they are in Australia, I'm in the UK) and explain what was happening, double check the email address and ask if they had been receiving my emails. The response was that the email address was definitely correct, they didn't use it very often and no, they hadn't been receiving my emails. They couldn't help me any more and so I thought maybe they hadn't realised they'd made an error with the email address. I emailed them on [email protected] but I heard nothing more.
Now the same thing has happened with another website. Whoever is using this email address has subscribed to a website, paid a fee for membership and I received all the emails, a receipt, documents that came with the purchase and also a login username and password. I logged into the site, it worked. Unfortunately there was no area where I could leave a message. Once again I have emailed them on [email protected] I have also searched for the person on Facebook using [email protected] and if I've found the right person they are only a young teenage girl. Again I have emailed them on [email protected] and asked them to contact me on another email address. I have heard nothing so I don't know if they received the email... I received it though!
I don't know how 2 people can be allocated the same email address but what is really worrying me is that if I am receiving emails intended for someone else are they receiving my emails?!!! That would really be a security problem as my email address is registered to lots of websites, my utilities etc.
Can anyone shed any light on how this can happen? I have put a telephone support request into Apple but the earliest was in 2 days.

The websites that she has signed up to I have logged in and there is no message asking for email verification which suggests she is receiving emails.
If they could sign in using an email address that isn't verified then all the website owner has is her word that she is receiving their emails. Besides, if there had been a verification email for these sites, you would have seen it too; which suggests that there wasn't.
Once you get the password changed they will not be able to receive any email from the account, even if they do now. That may not be the end of the problem, however, as there would still be nothing to prevent them from continuing to use the address to sign up on websites that don't verify the address. If it persists, you may have to either create a new iCloud account in order to get a new email address, or create an alias address to use within the existing iCloud account and stop using your main address for email. Then you can set up an email rule on icloud.com that sends email from the main addres to the trash where it is deleted 30 days later. This explains how to create an alias address: http://help.apple.com/icloud/#/mm6b1a490a. This explains how to set up an email rule: http://help.apple.com/icloud/#/mm6b1a3f8a. Good luck.

How can I connect two PS3 to the same Linksys WRT54G correctly

Hi,
i'm trying to connect two PS3 to the same routeur without having conflicts. Everytime i try to update my game softwares it tells me error 80710723 or now 8002AD23. I gave the two PS3 different IP adresses, i opened all the ports that Playstation suggested me to open (http://playstation.custhelp.com/app/answers/detail/a_id/241) and gave them different DNS adresses but still they cannot download any software content without bugging the console. I also use a PC, Tablet and Phone with my wireless connection.
thank you
-François

Well in this case the error code (80710723 ) is generated when the internet connection is slow. So you can try the following step:
# Open up the browser and on the address bar type 192.168.1.1 that will open up the Router setup page.
# Lower the MTU (Maximum Transmission Unit) from 1500 to 1400 or less (usually found on your router's main/ basic setup page)
# Make the Channel Width to 20 MHz only and Channel to 6, 9, 11..
#Adjust the following advanced wireless settings:
~~ Lower the beacon interval from 100 to 75
~~ Lower the fragmentation threshold from 2346 to 2306
~~ Lower the RTS threshold from 2347 to 2304

How to fix the "Two computers using the same IP address" issue on the airport express

I just bought an airport express and got dsl at my apartment, and I haven't been able to set up the wireless connection. My DSL works just fine but whenever I hook up the AX I get an error message saying that there are two computers using the same IP address on the network, but I only have one computer.
I know this is probably a simple fix, but I've never had this issue when I set up the Extreme at my parents house and I haven't been able to find a thread on this.
As of right now I have it set to Factory settings.
Help please!

This modem was designed to connect directly to a computer and you are trying to connect it to a router.
Unfortunately, this is not a simple fix as both the modem and your AirPort Express will need to be configured differently to work together correctly.
Connect the modem directly to your computer.
Open up your browser and type the default IP address for the modem into the address bar. Check your documentation on the modem but it is likely 192.168.1.254
That will bring up the configuration page for the modem.
You may need to enter the modem access code which is on a label on the back or bottom of the device
Look for an Advanced tab, then look for a tab labeled something like PPP Location
Right now, you will see that "PPP is on the modem"
Chance that to "PPP is on the computer or router"
Click to save your new settings and the modem will restart
If you ever need to get the modem back to its original settings, you will need to hold in the reset button on the back of the modem for 5-6 seconds and then enter in the default IP address to be able to access the settings on the modem
Connect the modem to the AirPort Express with an Ethernet cable
Open AirPort Utility on your Mac and click Continue to follow the guided setup to "Create a wireless network"
You may be asked to "switch" networks when you do this. You want to switch
Select the "Connect Using PPPoe" option when it appears
Enter your user name and password with your provider. Leave the Service Name area blank. You want to always stay connected if you see that option
Continue to follow the guided setup and Update to save settings
Pull the power cord from the modem, wait a moment, then restart the modem
Log on to the wireless network that you created during the setup and you should have an Internet connection

WRT54GS: without Windows, force a given MAC address to always get the same IP address via DHCP?

I have just now set up my WRT54GS to manage my home wireless network, and it works great. I just have one question that I haven't been able to find an answer for (forgive me if I have overlooked an obvious source of information).
I have set up the WRT54GS to be a DHCP server, and it assigns addresses in an ad hoc manner to all the devices that connect to it. In general, this is what I want, but in one case, I want a certain host to always get the same IP address, for example, 192.168.1.10.
You should know that I have no Windows machines on my network. Everything is either running Linux, MacOSX, or Symbian (on a Nokia N95 handheld). Therefore, I can't set up a static IP for my device using the software supplied on the CD that comes with my router, as that software only runs under Windows.
Using a different manufacturer's router, I am able to accomplish this by telling the DHCP software on that router to always assign 192.168.1.10 to the host who connects with a certain MAC address. I can then use this mechanism to force my specific host to always get this desired IP address. However, I haven't been able to find any way to do that with the WRT54GS without the software on the Windows-based CD. Is it possible at all? If I can indeed do this without that Windows software, could someone point me to some docs which explain how to accomplish this?
... or is there perhaps a different way to cause this to happen, perhaps by means of some sort of DHCP client ID?
Thank you very much in advance for any pointers you can give me.

Take a hippopotamus to lunch today.

Forget about the CD. There is nothing on the CD which you don't configure better through the router web interface at http://192.168.1.1/ You don't need the CD. Never. I have never used the CD to configure any of my routers. The program on the CD is just a software which helps you with the initial configuration of the router. It is just a software which pretty much contacts the web interface in the background and sends some settings changes there. You can do everything yourself directly. Then you know what you change.
You have to configure the static IP address on the computer and on the computer only, e.g. on your Mac use Static IP instead of DHCP in the network preferences. Enter the IP address you want to use for the computer, the subnet mask, gateway address and DNS server(s). That's it. The router is not involved in any of this.
You just have to make sure that you use an IP address inside the LAN of the router. By default, Linksys routers use the IP address 192.168.1.1 on the LAN side for the the router. The subnet mask is 255.255.255.0. The IP address together with the subnet mask says that all IP addresses 192.168.1.0-255 are considered part of the LAN. Everything else is outside and needs to be routed to the router and from there into the internet. (If you want to know how the subnet mask works exactly read the wikipedia article on it or search for "subnet calculator" or similar in the internet)
Thus, if you connect a computer to your LAN and set a static IP address on the computer it should be inside this IP address subnet/range in order to have internet and LAN access on the computer. It does not matter which address you use as long as it is inside the IP subnet. The DHCP server on the router automatically assign a correct IP address inside the IP subnet and also automatically assigns the correct gateway address (its own address = the address to which everything should be sent which does not belong into the LAN, i.e. the internet traffic) and the DNS server. With static IP you have to assign those values yourself.
But again, there is no Windows computer or CD involved to do that nor is there any configuration on the router required to set the static IP address on the Mac. The IP address you set must simply match your LAN IP which is basically defined through the settings on the router as you want to have internet and thus need access to the router and its address 192.168.1.1.
Some routers allow you define fixed IP addresses for specific devices in the DHCP server of the router. With that function you can set a fixed IP address on the router. The computer can remain on DHCP. It will always get the IP address you have configured in the list on the router through the DHCP server. However, your Linksys router does not have this option. If any device inside your LAN is supposed to receive the same IP address at any time you have to configure that on the device only.
If you have not changed the default LAN IP address, subnet mask and DHCP server settings on the router, the router has 192.168.1.1, subnet mask 255.255.255.0 and the DHCP server uses 192.168.1.100-149 for dynamic assignments. To avoid potential address conflicts you should not use any static IP addresses inside the DHCP server address pool. This leaves you with IP addresses 192.168.1.2-99 and 150-254 as static IP addresses inside your LAN. You can pick any address you like as long as any device with a static IP address has a unique IP address inside your LAN.
Assign the subnet mask 255.255.255.0 on the computer and set the default gateway to 192.168.1.1. The DNS servers are a little bit more complicated. Generally it is better and faster if you use the DNS servers of your ISP. You can, however, also use the IP address of the router 192.168.1.1 as DNS server. The router will then operate as DNS proxy, i.e. it contacts the DNS servers of your ISP for any request from your computer.
If you want to use the DNS servers of your ISP, click on the Status tab in the router web interface. It shows you the current settings of the router on the internet port. It should show you multiple entries for DNS servers. Choose those DNS server IP addresses in the computer.
If you don't want to go through the hassle with the direct access to the DNS servers of your ISP, simple use 192.168.1.1 as only DNS server on the computer.
There are all settings you have to make on your Mac or other computers to assign a static IP address. As long as the IP address is inside 192.168.1.* it belongs to the LAN and has internet access through the router (as long as the default gateway address is 192.168.1.1 of course).
Firmware is loaded either through the web interface of the router, usually somewhere on the Administration tab or with tftp. Both ways work fine on any Mac or Linux box.

Cannot connect two computers to the same game server HELP!

I have a Linksys WRT54G Router. I have two computers and I want to be able to use them on the same gaming server. Unfortunately, the game only have one port, so I can only port forward one of my computers. How can I configure my router to have two external IP addresses to the server so it won't kick one of my computers out. Thanks!

Hi,
I am in a gaming community and many members have a Linksys at home (but I don't know which kind exactly). Many of us try to connect two computers to the same server (many have a family). It seems it is a common problem that no one can connect two computers to the same game server.
I have a BEFSR41 V3 Firmware version 1.04.8
I use fixed IP address and no connectivity problem on Internet.
I have win XP SP2 on both computer.
I am using a DSL modem
I can connect the two computers to two different game servers at same time, but not the same server. Default port for this game is the same for all servers I use. I tried with both port forwarding enabled (in that case one PCs can connect the other not) or not (in the second case, whenever the second PC connects, the first one lose his connection to the server, no mater the order I try to connect my PCs).
Now the weird thing is that one member in my community just decided to throw away his Linksys router and he bought another brand (which I won't name to remains politically correct). Now, without changing anything in his PCs or his connection type, he can now play with two PC on the same server.
I am seriously thinking doing the same move. Since more and more game are now using Internet (and servers that controls piracy, $$) and family want to play together, not being able to connect two PCs on the same game server makes Linksys in bad situation from marketing point of view.
For example, in my gaming communtity, we now all know that Linksys can't handle two PC on same server, but other brand can...
Thank you in advance for your help.
