hi,

i don't see any static default route on your router.

could you post a show ip interface brief?

also, kindly add ip route 0.0.0.0 0.0.0.0 dhcp and add a DNS server on your DHCP pool dns-server 8.8.8.8 or an import all

ranishemer · ‎04-23-2015

Ok i will do it when i can, because i really need help!

Did you see my Network Topology?

Can i do a ip route to Ethernet interfaces?

Were you able to solve this problem because I have the same thing on a cisco 2951.

Georg Pauwen · ‎02-14-2019

Hello,

post your config. The initial poster seemed to not have a default route configured...
