Hello,

In a basic VPN l2l scenario using ezVPN, server  behind NAT device, client using 3G. What would be the reason to have in the output of the show crypto ipsec sa, a current peer different from remote crypto endpoint on the server ?

Thanks for your help.

Since it is behind a NAT device and NAT is only layer 3, and it doesn't modify any of the content of the IPSec VPN during the negotiation because it is encrypted, hence you might see current peer different from remote crypto endpoint on the server.
