Remotely connect to network with VPN

I'd like to remotely connect to our local network using VPN. I've tried vnc://external_IP.., but it fails with a message that screen sharing is not engaged.
How can I access this local network and specifically, individual Macs on the network?

First, you need to establish which VPN protocols can be used to connect to your network - your IT people should be able to give you this information. If it's a Cisco or L2TP/PPTP VPN connection, you should be able to use the Network Preferences to create a new VPN connection and use the appropriate login information to connect.
If you have an IPSec VPN system, you can use the free IPSecuritas to connect.
Either way, you need to get the detailed connection parameters from your network admin before you can connect from the outside world. Once you're connected, you should be able to connect to any local services (screen sharing, file sharing, etc) using local addresses instead of external IP addresses.
hope that helps
Matt

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

Remote connection to SAP(internet VPN) with Juniper Netscreen 5XT

Hi,
I am now setting up the remote connection (internet VPN) with the network device Juniper Netscreen 5XT.
Since I am not a network expert, I met some trouble on it.
We have prepared 2 public IP address. 61.xx.xx.45/29 for SAP router and 61.xx.xx.46/29 for setting up the VPN tunnel.
And we use 192.168.1.10/255.255.255.0(for example) as the private IP address of SAP router, and use NAT to map 192.168.1.10 to 61.xx.xx.45/29...
Any way, although the VPN tunnel can be set up, I can not ping the SAP router@SAP side.
But with the help of SAP, I did the test, use 202.xx.xx.xx(public IP address) as private IP address of SAP router, and did not use NAT, and registered in SAP side,I can ping the SAP router@SAP side.
I also think that use NAT of SAP router is a normal way to settup the internet VPN.
What's wrong with it?
Would you please give me some suggestion on it?
Thanks in advance.
Best regards,
Randy

It is OK after replace the network device as the cisco router.

Remote Connection to SAP with SAP Web Dispatcher

Dear Experts,
i have installed a SAP Router + SAP ECC 6.0 IDES + SAP Portal 7.0 + SAP Solution Manager 7.0. The remote connection works.
SAP Router is in a DMZ
SAP ECC 6.0 IDES + SAP Portal 7.0 + SAP Solution Manager 7.0 are in another network only for SAP Systems
Fo security reason, i would like to install a SAP Webdispatcher with the SAP Router's Server.
I already:
have extracted the icmadmin.sar file
have executed the sapwebdisp -bootstrap command
have started the web dispatcher with sapwebdisp pf=sapwebdisp.pfl
have activated /sap/public/icman and /sap/public/icf_info/* services inthe SAP Solution Manager
As the saprouttab file for the saprouter, i would like to establish the connection to SAP withe the SAP WebDispatcher.
My questions are:
What are the parameters i have to put in the sapwebdisp.pfl file?
Do i have to create the PERMFILE and the AUTHFILE?
Any example of profil file? (another than the SAP Library example)
Thank you very much for your help in advance.
Best regards.

I cannot print to my photosmart 7510 when connected to work with VPN

When I try to print to my printer while connected to VPN, I get an error that the software could not communicate with my printer. The IT department where I work has configured the VPN so that traffic to my local LAN is allowed (does not go through the tunnel). I had no problem printing to my old printer when connected with VPN (old printer was a photosmart 2510 connected via wireless network).
These symptoms lead me to believe that the printer software is attempting to connect to the internet when I send a print job to my local printer. Why is it doing that? What settings do I need to change to make it stop so that I can print while connected with VPN?

But I don't understand why the internet connection that my printer has comes into play when I'm sending a print job from my PC to my printer over my local network. I am not using the web services at all for that particular function.
At least I shouldn't be - I don't know what the HP print software installed on my PC is doing under the hood. The software shouldn't have to access the internet to send a print job locally. Nor should my printer have to access the internet in order to receive the print job from my PC.
What exactly is the printer or the print software accessing the internet for when I send a print job from my PC to my printer over my local network?

Unable to connect to network with Safari and Software Update

A user I support has encountered a problem with networking. He is unable to connect to the network with Safari and Software Update, but IS able to connect and surf with Foxfire and some other programs. Another unusual symptom is that he actually can connect to one web site (which is in his Bookmarks Bar) with Safari, but can't connect to anything else. He's also unable to navigate off of that one site he connects to. When he runs Network Diagnostics, he gets all green lights (no problems). He has fixed permissions, deleted Safari Cache and .plist, rebooted - not fixed yet. He's using 10.4.8 on a PowerPC G4. Any ideas appreciated (this is the wierdest I've seen in a while!).

Here's what he did. After reading your post, he created another location in his network preferences, entering EXACTLY the same info that was in his old location (he even used the old DNS addresses), except using a new location name. Then he chose the new location and "everything worked". It's one of life's great mysteries. Thanks for your help - it is appreciated.

Connected to network with no internet

Ok so this is an interesting situation...
We have two networks in two building across from each other. I can connect to network 1 with no problem and access the internet.
On network 2, however, I can only get on the LAN and do not have complete internet access...as of a this morning. I changed nothing between last night and this morning (perhaps windows updates???). In fact, I checked my email this morning and then when I
came back, could no longer access the internet.
I have full access to the LAN on network 2, I can ping websites, but cannot use a browser to visit sites. I have done all the ipconfig release/renew/dnsflush commands that I know of/found on these forums. Other people DO NOT have this problem. It is just
my computer.
Any help is much appreciated!

Hi,
Did you set any proxy?
If you can ping a host but not open it in a browser, then I suspect that your browser settings have been compromised. Check for any proxy settings that may have been configured by malware.
Furthermore, please try to reset your Internet Explorer to check if the issue could be resolved:
1. Close all Internet Explorer windows that are currently open.
2. Open the desktop, and then tap or click the Internet Explorer icon on the taskbar. Changing your settings will affect both Internet Explorer and Internet Explorer for the desktop.
3. Tap or click the Tools button, and then tap or click
Internet options.
4. Tap or Click the Advanced tab, and then tap or click
Reset.
5. In the Reset Internet Explorer Settings dialog box, tap or click
Reset.
6. When Internet Explorer finishes applying default settings, tap or click
Close, and then tap or click OK. You'll need to restart your PC for these changes to take effect.

Multiple gateway on the same network with VPN

Dear all,
i have problem of multiple gateway with VPN, please refer to the attached pics:
PC B cannot ping PC A if PC A's gateway is not pointing to the VPN Router
if i change the PC A default gateway to 192.168.1.2 ( VPN router) , then PC B can ping it. but the fact is we have to keep the default gateway stick to 192.168.1.1 . is the any way to make it happen ?
Thx

Hi,
Can you add static route on Linksys router 'ip route 192.168.2.0 255.255.255.0 192.168.1.2' and give a try..?

Can't connect to network with mac, only pc.

I have a powerbook and have just installed an airport extreme card. I do not have my own internet connection and intend to 'borrow' connections that I pick up.
In the past I have used a friend's PC laptop &belkin wireless adapter to connect to networks accidentally found in both his house and mine. This was no problem whatsoever and a connection without passwords etc was possible in both.
When I try to connect my powerbook the following happens:
1. In his house: I can connect to an open apple network but the connection is unbearably slow while I can work on his computer from the same point relatively easily.
2. In my house: When I try to connect I get 'error in connection to linksys' or similar (maybe even get asked for passwords).
I have very limited knowledge of these things and have no idea what it means or what the problem is.
If anyone can tell me why the connection always seems to be slow or unachievable on my powerbook (when an old PC laptop succeeds) I'd be most grateful.

It could be as simple as the owners of those wireless networks didn''t want other people using their networks and have added a layer of security.
One you may also want to have a look at these recent cases involving using other people's wireless networks.

UM175 - Not able to connect to office network with VPN

I am having trouble connecting to my office network using this wireless card, UM175, and connecting with a VPN. I have the VPN set up the same as many other computers connecting to our server. Currently when I start VZAccess, I can access the internet and everything works fine. When I start my VPN to connect to my office server, it takes multiple tries with error 691 being returned. After two or three tries it connects. I can ping my computer from the server. I can ping my router and my server from my notebook with the UM175. However, I cannot do anything with the server. I cannot access the internet, access files from the server, or access any software on the server. I contacted IT and our administrators and they tested the system and VPN and state that there is a problem with the modem UM175. Is there some setting that I must set to make this work correctly. This is an urgent matter and must be working, or I will have to purchase another type of modem.

Where are you located? I'm in the Bay Area, CA and I was using the UM175 with my PPTP VPN without any problems. However, I recently upgraded to the new 4G on Wednesday and now the PPTP VPN won't authenticate...errors on verifying user name and password. I did a packet trace and found GRE packets are being dropped. This is a Verizon issue and it appears their 4G upgrades have directly caused this problem.
There is another thread about this issue located here: http://community.vzw.com/t5/Broadband-Netbook-MiFi-Devices/LG-LTE-Modem-VPN-Not-Working/td-p/349846

Could not connect to ESS when using vpn or remote connection to network.

Hi,
Our users could not connect directly to ESS when they are using vpn or dial-up. The ESS link would ask for user id and password. There is no problem when they are directly connected to the office network. The ESS page will display directly when they click on it. It will not ask for user id and password. We are using Single Sign-On.
thanks,
krbas

I have solved the problem.
The problem was solved by including the url of our server in the exception list of the IE proxy settings of VPN.
Thanks to me. :-D
Now.... How can I assign points to myself?

Can't reliably connect to network with 5 AEs config'd with 'extend network'

To accommodate a large house, thick walls, and detached guest house I setup five airport Ex's using the 'extend network' option. One is connected to the cable modem and the other four extend. All four get green lights. I get good reception in most places but it appears that I often don't connect to the closest AE, even when only a few feet away. In some cases my signal will go from full to zero in the span of a few feet. The network is the all n/5Ghz mode.
When checking the logs of each of the AEs I found that I wasn't connecting to the closest unit and in the case of the farthest AE I never connected to it. When I stepped a few feet away from the farthest AE I lost all signal.
1. There's no relay or remote option when 'extending network'. Is there a way to force connection to a particular AE?
2. Is there a way to prioritize among the AEs? Like with networks.
The logs show three AEs connecting to the Main AE and the fifth one connecting to one of the the three relays. Is there a maximum daisy chain length?

I checked my 4 extremes and found that the 3 mac mini's, 2 powerbook's, 1 imac, and 1 xserve do connect to the closest extreme.
I have 1 extreme in the middle of the 2nd floor as the gateway. An extreme on the third floor for 2 mac mini's, an extreme on the far end of the second floor for an imac and a powerbook, and extreme on the 1st floor for a mac mini, powerbook, and xserve.
One item for consideration to help control access is by manipulating the min connect speed dialog box. The default is 1 mb. Up that number until your clients become ineligble to connect to distant routers. As cleints move away from routers, their connection speed reduces.

Unable to connect to network with a new Laptop. ( WRT160n v3.0.02/3 and WRT54G2 v1.0.01)

Hello,
I have never had problems with a Linksys router before until I recently got a new laptop. It was fine for the first few days, but then the connection started dropping and wouldn't come back unless I turned off the router and back on. This started increasing in frequency, so I decided to tweak with my router to find the problem and see if I could solve it.
This was for a WRT160n v3.0.02 I looked up several suggestions online and decided to update the firmware to v3.0.03 This seemed to only make it worse as I could no longer connect, and when I turned the router off and back on it would allow me in for about a minute and drop me right away. I decided to do a factory reset and set up the network all over to see if this would fix it. Nothing.
I started tweaking with the settings, and came across some posts here such as this one, started tweaking with the channel settings and everything. Nothing. If anything I somehow made it worse since now instead of dropping repeatedly it wouldn't connect at all except for about a minute after restarting router, then it would drop completely (I would either get the limited access notification or I simply couldn't connect and windows said to unplug the access point. (...again)
Fed up, I recalled I had another Linksys router that I wasn't using in storage, a WRT54G2v 1.0.01 so I set that up, no problems... at first. All other devices picked it up right away, but once again, my new laptop decides it's too good for the freaking network and drops it repeatedly telling me there's a problem with the access point.
So at this point I'm thinking it might NOT be my network, but my wireless card or something, I uninstalled and reinstalled, updated drivers, (I use a Realtek RTL8723AE Wireless LAN 802.11n PCI-E NIC) I even came across this article and disabled browser service and NETBios (including all other devices on my network). It brought back the network on my laptop for a bit, only to smugly come crashing down again.
I've tried setting a static IP, I set my priority to highest on QoS, I've tried factory resetting both routers TWICE. I'm at my wits' end and I dunno what else to try, I'd greatly appreciate any help I can get.
I have a cable connection, modem works just fine, signal is fine if I connect it directly to modem, also if I connect it through the router, no problems whatsoever, the only problem seems to be the wireless on my new device. OTL

Determining and setting up the correct MTU size

Direct-connect inside network with dynamically assigned IP-addresses

I have 13+GiB of files to transfer between two computers (one arch and one Win7) and would rather not spend the day moving them ~1GiB at a time via flashdrives.
I have tried setting up an ad-hoc network on the win7 machine, but wifi-menu fails to connect to it.
I have tried setting up an ssh server on the arch machine and accessing it via PuTTY on the Win7 machine.
I have tried setting up an apache server on the arch machine and accessing it via firefox on the Win7 machine.
I do not have the permissions to statically assign ip addresses on the network, and need to somehow directly connect between these two computers. Any suggestions?

Post the exact commands that you are using and the exact error messages that you receive.
For mounting windows shares I use variations of the following command:
mount -t cifs //<windows ip address or host name>/<windows share name> /mnt/foo -o nosetuids,uid=<your local user id>,gid=<your local group id>,user=<windows user name>,workgroup=<windows workgroup>
Have you tried something similar? It should "just work".

[solved] Can't connect to network with 64-bit kernel

On 64-bit Arch Linux, I can't get any network access. On 32-bit Arch Linux, I can connect to my router with an ethernet cable or a wireless card using dhcpcd or networkmanager.
In 64-bit, I have tried
- Upgrading my kernel from 3.3.8 to 3.4.2 from the testing repos
- Getting networkmanager-git from AUR
- Using the r8168 driver for my ethernet card (which is actually exactly the same one as the one from https://wiki.archlinux.org/index.php/Co … k_messages )
But I haven't been able to get "dhcpcd eth0" to tell me anything but
dhcpcd[677]: eth0: sending IPv6 Router Solicitation
dhcpcd[677]: eth0: broadcasting for a lease
dhcpcd[677]: eth0: sending IPv6 Router Solicitation
dhcpcd[677]: eth0: sending IPv6 Router Solicitation
dhcpcd[677]: eth0: sending IPv6 Router Solicitation
dhcpcd[677]: eth0: no IPv6 Routers available
while "dmesg | tail" fills with
eth0: no IPv6 routers present
eth0: no IPv6 routers present
eth0: no IPv6 routers present
My rc.conf has the correct settings for dhcp:
interface=eth0
address=
netmask=
broadcast=
gateway=
I can get whatever 64-bit packages I need to get the internet to work in 64-bit linux by downloading them in 32-bit linux and then upgrading to 64-bit linux.
My goal is to get networking to work on 64-bit linux through either eth0 or wlan0 (eventually I'll need wlan0 but right now neither works, so if one starts working, the other probably will), or for someone to say "It's impossible dude, go download opensuse and see if you get a different damning error over there".
Happy trails,
jc
