I have a 2921 Router and I can ping my entire network from the router but nothing can ping it from either side of the router. I know this is something simple but I can't figure it out.

Let me know what stupid thing I missed.

Do you have access-list applied to your router interfaces?

No ACL. I am running eigrp as well. From the outside I can ping the outside interface but from the inside of the network I can ping everything but the router interface.

Can you pls share the router config?

If you perform a traceroute, where does it fail?

Could it be any ACL in the path between your inside network and the router?

Which IP address on the router are your trying to ping

If it is one of the subinterfaces do you have the client you are pinging from in the correct vlan
