Cisco 2610XM T1 setup

Hello,

I’m having a problem setting up a 2610xm as a basic router. From the console of the router I can ping the Internet (yahoo.com, etc) but from the host (78.x.x.3) I can not ping past the router. I can ping the FastEthernet0/0 and the Serial0/0.1 interface ip addresses, but can not get past that. I want the host 78.x.x.3 to have full access to the Internet and have the Internet have full access to the computer on 78.x.x.3.

Here is my config, thanks in advanced:

hostname 2610XM

Remove the access list 100 on your FastE0/0

Only use one access list on the serial0/0.1

access-list 101 permit ip 78.79.223.0 0.0.0.15 any

access-list 101 permit tcp any any established

access-list 101 permit ip any host 78.79.223.3

access-list 101 permit ip host 78.79.223.3 any

I got rid of the access list 100, and used the 101 on the serial0/0.1 but am still having a problem accessing the Internet with the host computer. Are these the correct network settings for the host computer?

IP Address = 78.79.223.3

Sub Mask = 255.255.255.240

Def Gateway = 78.79.223.1

DNS = 78.79.223.1 & 78.79.196.6

If these are the correct settings for the host computer, can you see anything else I'm missing in my router config?

Thanks

hmmm? ya, that all looks fine. Try removing the access list 101 from the serial int. Those are all public addresses, so you don't need to do any NATing.

you config :"interface FastEthernet0/0

ip address 78.69.223.1 255.255.255.240"
