Hello,
I have a Cisco 2620xm Router with a c2600-ipbase-mz.124-12 IOS installed....also have a NM-1FE-TX module.
I connect Ethernet0/1 to the cable modem and Ethernet0/0 to the lan.
Ethernet0/1 is getting a valid ip 65.xxx.xxx.xxx from my ISP........and ethernet0/0 has a fixed lan ip 192.168.xx.xx
Ethernet0/1 has NAT (outside) and Ethernet0/0 has NAT (inside)
I tried a static route 192.168.xxx.xxx 255.255.255.0 65.xxx.xxx.xxx ........that did not work.
I am NEW to Cisco routers so I am sure I missed something?
I get no internet access...and cannot ping the 65.xxx.xxx.xxx ip.
Any thoughts?
Solved! Go to Solution.

Assuming you have already NAT setup properly you just need a default route on the router to point to e0/1. If you already haven't configured a default route then configure the following command from config mode;
ip route 0.0.0.0 0.0.0.0 e0/1
If you are still having problems posting the full configuration would help.

Your NAT config should something like this if you are trying to do NAT overload.
Router(config)#ip nat inside source list 1 interface e0/1 overload
Router(config)#access-list 1 permit 192.168.xx.xx 0.0.0.255 --> substitute your e0/0 subnet address and wild card mask here

Excellent.......I am now runnig thru the router...
I just updated the IOS to c2600-adventerprisek9-mz.124-11.T
So I configured the firewall....
The whole purpose of this was to BYPASS and possible eliminate the ISA SERVER...
I may try to configure the router >> ISA server.....
I just wonder if i get better performance from router only...
I only have a couple of users....
THANKS AGAIN....
