I'm using a Cisco 1921 with a VWIC2-2mft-t1/e1 to convert a T1 handoff from the ISP to a single ethernet.
I configured the T1 and is up, from the router I have internet access(i can ping 22.214.171.124). on the Gigabitethernet 0/0 I have a computer and configured a DHCP server on that port with 10.10.10.0/25. also, I have the default static route pointing to the serial interface.
The problem I'm having is that from the computer I cannot connect to the internet. I'm able to ping only 10.10.10.1 but cannot ping the next hop 126.96.36.199. I attach both my config and static routes. I've tried different static routes but I cannot make it work.
Thank you for any help in advance and let me know if you have any other questions.
Solved! Go to Solution.
I noticed your have default gateway, not ip route 0.0.0.0. Def Gateway is used for switches.
Can you remove your ip default-gateway 188.8.131.52 and insert ip route 0.0.0.0 0.0.0.0 184.108.40.206 instead?
It is true that the original config did include ip default-gateway. And it is true that this command is not used if ip routing is enabled. But that does not necessarily indicate that the command should be removed. Because the original config also included an ip route 0.0.0.0 0.0.0.0n serial 0. So the routing in the original config was ok. And that is why the router was successful in ping 220.127.116.11. @Filip Knezevic is quite correct that the significant issue is that the original config did not include address translation.
Thanks for the observations. Indeed I missed there was an ip route command as I was in a hurry.
But definitely his issue is that there is no Port Address Translation configured.
I still think it's not bad that the the unnecessary ip-default gateway command was removed, though it wouldn't break anything if he left it.
