Access to Internet Routing Entries

Hi!
I know that list of structures ire_t contains routing information of host. But where is the head of this list? What is it's name? Maybe somebody knows. My idea is to get IRE list's head and find entry that contains default gateway.
One thing else: I've noticed that default gateway aren't tied to any interface in Solaris operating system.
How can I realize which interface my default route goes through?
Thank you for any help.

As you do not have a router, you can use RRAS to achieve that. The first thing is to make the traffic routed to internet.
Ping and Tracert can be helpful.
The second part would be the DNS resolution. You can configure your internal DNS servers to have your ISP DNS servers as forwarders and make your domain-joined servers / computers point only to your internal DNS servers as primary and secondary DNS servers.

I want to change Router2's Operating Mode from "Gateway" to "Router" because I
want to turn off NAT on Router2 so that I can access all computers attached to
Router2 by their individual IP instead of using port forwarding at Router2.
The problem is after the mode change from "Gateway" to "Router", and regardless
whether I disable RIP or enable RIP, and on what interfaces it is enabled, computer
192.168.2.160 does not have internet connection.
Observations:
[0] INTRAnet works as I can reach computer 192.168.2.160 from computer behind Router1
192.168.1.x and vice versa.
[1] ping and traceroute *work* on Router2 itself using the built-in dianostic tool.
[2] nslookup on computer 192.168.2.160 always works on new lookup. It uses
192.168.2.1 as the resolver.

This is not expected because NAT to internet should still be done by Router1, no? Computer
behind Router1 with IP 192.168.1.x has internet connection.
[5] It looks like I cannot change the Routing Table Entry on Router2. I do not think I need to change anything,
just an observation.
[6] If I use LAN to LAN connection, then both intranet and internet works. [The internet IP of Router2 can be
anything not in the same subnet of the Router1, and DHCP on the local side should be disabled to avoid conflict
with the the DHCP on Router1].

I have a question. Unfortunately in order to ask my question, I have to have a lengthy description of my setup. Basically, I have a second Linksys router in "router" operating mode with NAT disabled connected to the Verizon router, and I have a computer which is in a different subnet (192.168.2.x) behind the Linksys router. This computer can communicate with computers behind Verizon router in subnet (192.168.1.x), but cannot reach internet. This is a simplified version of my question, full details are in the original post.
If I setup the Linksys router in "gateway" operating mode, which means with NAT enabled, then both intranet and internet works, but there is no easy way to setup port forwarding for 10 compueters in 192.168.2.x network to communicate with 10 computers in 192.168.1.x network.
If I setup the Linksys router in a LAN to LAN configuration with Verizon routers, but this way all computers are in the same subnet, I want them to be in different subnet for access control and things like that.
I hope this makes things a little clear.
Thanks.

No internet access from WRT54G router -see details please-

I can connect to "linksys" as a wireless network, but get no internet access. Please help! Thank you!

The settings that you provided is for the modem so I suppose you can able to go online with modem… Please let me know the IP address that you receiving from the modem… Since the connection that you have is DSL connection and if you are receiving the IP address from the modem under LAN (Local Area Connection) is a Private IP address (192.168.X.X) then follow the steps:
# Connect the modem with the Linksys Router WRT54G on the Internet Port and then connect the Computer on any of the Ethernet Port on the Router (Numbered – 1, 2, 3 and 4)…
# Open up the browser and on the address bar type 192.168.1.1 that will open up the Router setup page…
# Look for the Local IP Address and change it to 192.168.2.1 …
# Click Save Settings...
# Then Click on wireless Tab create the Wireless Network Name SSID and select the channel to 6, 9, and 11… Click Save Settings...
# Then Click on Wireless Security sub tab and select the security mode and provide the password as per the requirement… Click Save Settings...
# Click on Status Tab on the Router Setup page check if Internet IP Address has numbers or values. If the Internet IP Address has numbers, the computer should now be able to access the Internet. If the IP address is all zeroes (0.0.0.0) click "IP Address Release" first then click "IP Address Renew". If the IP address is still all zeroes, enable PPPoE on the router.
To enable PPPoE on the router you should have a username and password provided by the ISP (Internet Service Provider) and follow the steps...
# Under the Setup tab, set the Internet Connection Type to PPPoE…
# Enter the Username and Password that your ISP provided, including the domain in the User Name field if necessary…
# Click Save Settings...
# Then Click on wireless Tab create the Wireless Network Name SSID and select the channel to 6, 9, and 11… Click Save Settings...
# Then Click on Wireless Security sub tab and select the security mode and provide the password as per the requirement… Click Save Settings...
# Click the Status tab then look for Login Status and check if it says Connected. If it’s connected, you should be able to access the Internet.
After doing the following settings then connect the wireless computer the preferred Network… Once it gets connected you will be online wirelessly as well…

After a router reset, can't get second PC to access the internet

I had my wireless router (WRT54G) and printserver working fine and then a problem with my DSL had me resetting both boxes (yeah I should have know better). I've fought back and have everthing working for one PC that has an internal wireless but my other PC has a WPC54G wireless card and I can't get it to work. Both PCs are XP, SP2. The Linksys appl says that it contacted the access point but can't access the internet. It has always been flaky about this but usually gets to the internet. It does have a good IP address, the WEP key and channel are right but 'no joy'. I can ping the router and the printserver but I can't bring up the router's home page but I can print to the printserv. I did not change the modem to 'bridge' yet.
TIA....jack

What is the IP Address you are getting on the computer...?It should be in the range of your router.IP Address should be 192.168.1.x, Subnet Mask : 255.255.255.0, Default Gateway : 192.168.1.1 (assuming your router is 192.168.1.1)...
If you get the above mentioned IP Address, Subnet and Gateway Address then you should ping the Gateway, type ping 192.168.1.1 and press Enter...If it gives you request timed out then disable any firewalls, security software on the computer...
If you get 4 replies then type ping 4.2.2.2 and press Enter, if you get request timed out, then you need to upgrade your router's firmware...If you get 4 replies then type ping yahoo.com and press Enter...If you get replies for Yahoo then you should get the Internet after adjusting the browser settings...
Adjusting Browser Settings : Open an IE, click Tools >> Internet Options, then delete all files, cookies, history, forms...Goto "Connections", make sure Never Dial a Connection is checked, click on LAN Settings and make sure all the options are unchecked...Once you are done click on O.k...Close the IE and re-open it...
If yahoo times out then provide static DNS on your WAN Connection...
Click on the Start button >>> Settings >>> Control Panel >>>Network Connections- Right click on the icon for Wireless Network Connection and go to properties- On the 'General' tab select 'Internet Protocol TCP/IP' and click on the Properties button- Select 'Use the Following DNS Settings' Preferred DNS 4.2.2.2 Alternate DNS - 4.2.2.3>>Click on Ok button to Save and Click on "Close" on main Properties window...You should be able to go online...

Trouble accessing the internet on a WRT54G wireless router

I’ve run into a problem setting up a wireless network at my friends’ house. The problem is accessing the internet from the wireless PC that has a WMP11 Wireless PCI Card to a WRT54G wireless router.
The wireless PC is running Windows XP and it sees and connects to the router with “excellent” signal strength but will not connect to the internet.
The router is currently set to WEP 128 bit encryption security. I’ve tried disabling the wireless security all together but when I do that the wireless PC no longer sees the router.
I have no trouble connection to the internet thru the wireless network I have set up at my house when I bring his computer there. But my router is an older Linksys 802.11b so maybe that’s why.
Anyone have any ideas what I should try other than telling him to buy a new wireless G adapter card?

If earlier your Wireless Adapter is working fine with the same network & computer .... try upgrading the drivers of the aqdapter .... from http://linksys.com/download .... uninstall the older drivers & reinstall newer drivers ....

Is there a way to access the web-based setup for my router if I cannot access the internet?

Okay, I need to change the ip address settings on my router. I have a WRT54G Wireless router. I cannot access the internet on my computer connected to the router, and do not know how to change the router settings without accessing the web-based setup page. So, back to my question. Is there a way to access this page if I cannot connect to the internet?

On the back of the router is a small reset switch. Using a paper clip or other small item, press the switch in and hold it for a few seconds. This will reset the router to the default IP address of 192.168.1.1. Enter that address in your web browser, and be sure your computer is attached to the router by an Ethernet cable. Don't attempt to do this using the wireless connection.
Once you have reached the web configuration utility you can change the DHCP settings.
To give your PC a static IP address you will need to open your network connections panel and, assuming your using Windows XP, make the changes from dynamic IP to static there.

WLC Guest Access Internet Routing

Not sure if this the right forum, but i'm wondering if anyone can explain this.
I have a trunk from the wlc to my router with one switch in between.
wlc---trunk----3560---trunk---2821
The interface on the wlc and the 2821 both have an ip address and can ping each other. When a wireless client connects to the guest network they cannot access the internet unless the 3560 switch has an ip address set on the vlan that is trunked from the wlc to the router
wlc(vlan 825 - 10.7.200.2)----trunk-----3560(vlan 825 - 10.7.200.3)-----trunk-----2821(vlan825 - 10.7.200.1)
The gateway for the clients is 10.7.200.1 which is the router. If i take the ip address off of the vlan interface on the 3560 the trunk is still there, but the clients on the guest network cannot get through. The gateway on the interface on the wlc is also set to 10.7.200.1
Any ideas why I need that ip address on the 3560?
Dan.

Hi Dan,
you may send the switch "show tech" and the WLC "show run-config" taken with the problematic config for a quick look.

Federico

Can't get internet access with WRT54G router

I recently purchased a used WRT54G. I replaced my old wired linksys router with it and my hosts are able to get dhcp addresses from the router, but they cannot access the Internet. I have tried to use dchp release and renew buttons under the status tab in the router's web-based gui to get a public IP address, but can't get one. I have attempted to reset the router to its factory settings, but I still can't get the public IP. I have no problem getting an IP and Internet access with my old router and the WRT54G works if I disable its dchp and daisy chain it to the old one. Maybe I need to do something else for a complete reset of the router. Any suggestions? Thanks, Jack

the router that you just purchased was maybe configured for a different network before that's why it did not work initially. after making the router back to its' factory defaults, you should reconfigure or set-up the router.. If you have CABLE ISP, enable ''mac address clone'' on the router's set-up page under the set-up tab. then check if you can get a public ip address after that.

I connected my BEFW11S4 router but still can't access the internet.

I have a BEFW11S4 Linksys router and I have connected the right wires and everything and I still cant access the internet.. I go to network connections and i see that the connection i'am using says ' connected' so what gives? I load the browser and it says problem loading page.. can somebody assist me please??

I'm actually the 15-year-old son of the person this account is signed up for (he's making me fix it because he has other things to do), but anyway, I'm experiencing the same problem, but I will go into a bit more detail than Estilo to verify it is the same and hopefully get a bit more help:
My dad's computer can connect straight to the modem (MSN Arescom NetDSL 800) and run the internet just fine, but only his computer; I've tried plugging my Xbox 360 directly into the modem, and it cannot connect because the ISP knows that it's not my dad's computer...?
But the internet will not run through the router to any computers connected to it. My dad's computer is even wired to the router, and still no internet. We've found that it's an IP issue, and trying to change that doesn't work as it give us a "169" IP (a "router is there, but I can't communicate with it" IP address) whenever we try to fix anything, rather than the "192.168.1.1" or ".2" that we should have.
My dad thinks (and I'm not entirely sure he's correctly, but I mostly agree with him) that the computer is the actual central hub for the internet, as in that it runs the administrative settings and makes the internet actually work for the rest of the computers (if his computer isn't on, no other computer can connect to the internet); the router is basically just a splitter.
The thing is, though, that this problem started randomly about 2 weeks ago as my dad was just looking up some things on craigslist.com; that was the point when the IP addresses changed completely for an undiscernable reason. And 2 weeks ago, my computer was able to connect to the router wirelessly and access the administrative settings. My cousin (who works in this stuff) recommended that I see what I can do to fix the problem by editing the administrative settings from my computer, but now I cannot connect to the router whatsoever.
My dad and I have narrowed it down to a driver problem, and I'm not sure what to do about it. The reason for this is we tried getting a new router (the WRT54G), and the same connection issue remained. If this is the problem, you know what the problem really is, or you have questions, let both me and Estilo know.
Simplified Outline:
+ comp to modem (MSN Arescom NetDSL 800) [working]
+ comp to router (BEFW11S4) [failed]
+ comp to new router (WRT54G) [failed]
+ router to internet [failed] (incorrect IP to connect to ISP)
+ not a router problem
? driver problem
? designated computer needed as central hub
- wireless connection to router was recognized (no longer works?)

WRT54G router cannot access the Internet

My wireless PC can access the router but cannot access the Internet.
When I ping linksys.com - the ping times out; however, when I ping my ISP I get 4 pings back. When I ping the router the ping is successful as I get 4 pings back.
I am sure there is a fix for this problem. Can anyone help me get connected to the internet?
Thanks
I just got DSL in my area and installed it. I have a Linksys WRT54G router and a zyxek 660R DSL modem. I have a PC #2 in the room down the hall and a PC #1 in another room. I have a Wireless-G USB adapter in PC #2 (this is the antenna for the wireless connection). Everything is installed and PC #1 can connect to the internet through the modem and router. However PC #2 can only reach the access point (router) and will not access the internet. I can connect to the internet for PC #2 when an ethernet wire is used directly but it is not great to have a wire running down the hall. I pinged the router from PC #2 and the echos look fine. So it can certainly reach the router. When I use the Local Network tab and click on DHCP Clients table both PCs are displayed. So how can a PC use a wireless connection to reach the internet? I have spent 4 days already trying to get this to work. My ISP can't seem to help.
Thanks for your help.

hi... logon to router's setup page and try changing channel to 1 or 11, click on the advanced wireless settings and try reducing beacon interval to 50, fragmentation and RTS threshold to 2304, also try upgrading latest firmware on the router...also
if you are using Win XP system try uninstalling the adapter from the computer...click on start >> programs >> wireless G USB adapter >> uninstall, put the CD in for the adapter and restart the computer, one window pops up "found new hardware" try installing the drivers, no need to install WLAN software or utility and use windows WZC (wireless zero configuration) to manage wireless connection...check whether it works for you or not and let me know the results.

I don't have a DSL or cable modem to access the Internet ... just a mobile WiFi (there is no cable available at our house). How do I connect my Time Capsule to the Internet via the mobile WiFi?

LOL!!
I am in Australia and the ISP... I think both the main ones would fit your description to a T.. big T in particular.
Your router is really unsuitable.. if it is only wireless and no ethernet.. just buy an ethernet one.
Do a search on ebay.. 3g router.
But you can get the TC to join a wireless network.
It is a non-standard setup that Apple will not support.. the option is hidden.
If you are on Lion download the 5.6 utility. Go to the wireless set up page and hold down the option key whilst selecting wireless mode.. a new option, join will appear. You can then put in the ssid and passkey of the 3g router.
But please note the end result of this setup..
very slow speed. The TC is now a second wireless hop from your clients.. this will halve the speed.
In this mode the ethernet are deactived.. for reasons only Apple know, they decided you should not use ethernet when doing this.

I cannot access the internet the screen is grey, I have tried by using the answer from someone but it does not work...I went to settings, tap safari, then clear the history, cookies, and cache, then turn off ipad. When I did that twice, it did not work. How long does it take for the clear history to work? I am a brand new
user of the ipad2 and I am disappointed that this is happening already.

Have you been able to access the internet previously and now it's suddenly not working, or are you still trying to access the internet for the first time on your iPad? Are you at home trying to connect through your home router? If you are at home, did you put your home routers encryption code as your password? The encryption code is what your iPad is looking for and it is usually found on the router and is typically a 13 digit combination of letters and numbers. Let us know......

I did a software update on my ipad and now cannot access the internet. how can i fix this?

I did a software update on my ipad to 8.1 and now cannot access the internet. How do I fix this? My mail updates, but to get internet access I had to move from wifi to cellular data, and now even cellular data does not allow me access.

Hi Go to settings Reset Network Settings After Reset you need to enter your Router wireless key Before you do this turn off your Router for 30 seconds Also an option is to go on Websites for your make of Router look for any Firmware updates but you can do this later. Cheers Brian

Sounds like a bogus pop up. In any case power down your Mac, your modem, your router. Then power back up in 1 minute sequence; modem, router, Mac.
