I have a problem with all traffic in the router, included VPN, when add NAT router-map configuration.

If I modify the NAT configuration without route-map commands, all traffic work perfectly.

I don't understand what happen

I don't know if I need apply the router-map policy in the nat inside interface?

It is difficult tell what could be the problem without looking at the configurations. VPN with NAT in the path will have some challenges. This is because, NAT (and also PAT) modifies the outside IP headers (and port numbers in PAT) when the VPN traffic corsses a NAT/PAT device. This causes the ingerity check to fail at the destination end.
