We have a IPSec peer. Everything works great..IPSec established, from the router I can ping/connect to the remote hosts, but the clients are not able to connect. There is no NAT involved. When pinging any remote IP from the router using the source IP...
So the problem was not in the crypto maps or the ACL, but CEF was enabled and it was causing this issue. As soon as we did a 'no ip cef', it started to work from all the clients.
Yes both phase 1 and 2 are up and the router is also able to ping the remote hosts. We tried with different hosts but it doesn't work from the clients.
