I had used this configuration for years in New York, now that I moved to Florida. It's not working. I can ping the default gateway and the Dns server that Adelphia (the cable company) gave me. However the web sites will not open.
I used the command show ip nat trans to see what happens when I open the broswer. I goes to the web site but doesn't open it.
Does anyone know how to fix this problem?
 
I can't anything wrong in your config. Maybe you want to get in touch with your ISP, they might have given you some wrong info. Ping an website and fill in the ip address in your browser..maybe its a dns problem...if not a browser problem.
 
I have tried just entering the ip address in IE and Mozilla.
That doesn't work either.
The dns server is working because on the router I pinged and it converted it to the IP address.
When I connect the cable modem directly to the PC it works perfectly.
 
I do used my config for years with Cox and I recently moved to an Adelphia community and have the exact problem. I believe you need to upgrade your IOS to 12.3 or higer because Adelphia willfully blocking our "IP Address DHCP" from obtaining an IP. Let me know if you getting working.
 
Jamin123 did you upgrade and is your router now working?
I am obtaining a IP add because when I check the interface e1 It has an IP add.
But I'll try the upgrade.
Thanks for the reply.
 
Did you get a public IP on E1? I got a private ip on E1 (10.x.x.x), but a public ip when I directly connect to the modem. I noticed that an installation script ran from the 10.x network, then the second phase of Adelphia setup issues the public ip. This setup script can't run on a router.
 
Yes I do get a private IP on e1. What's the solution call Adelphia? Did you ever get yours to work?
 
The private IP is the culprit. You need a public IP on E1 to communicate on the internet. I'm afraid to call Adelphia because they told me not to use Cisco routers, so I'm using my SB4200 modem until I get an IOS upgrade.

Why don't you call Adelphia and let me know what they say?
