Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

we have the following config in Cisco 2811:

interface FastEthernet0/1

ip address secondary

ip address secondary

ip nat inside

( goes via IPSec to another routers)

ip nat inside source list 101 interface FastEthernet0/0 overload

ip nat inside source list 103 interface FastEthernet0/0 overload

access-list 101 permit ip any

access-list 103 deny ip

access-list 103 permit ip any

everything works. the hosts inside and the hosts in 10.90.* networks connected via IPSec can see each others, the remote routers can see this Cisco 2811 as well.

But Cisco can't see any router or a host except a hosts in the local Small but annoying problem.

how can I solve this? help plz.

This is most probably because when you try to ping(?), .. remote host from the cisco device the source IP is not
If you run a ping, try doing an extended ping to only running "ping" you will be asked for the source internet/ip to use, put and it should work
