Ipsec site to site connection with strongswan behind nat, can't access remote

daiqingxu

I have setup an ipsec site to site connection with strongswan on the other end behind nat. Currently i can't access remote resource while i can access local resources from remote.

Tcp dump seems the packet is send to remote end.

15:38:39.245009 Port1, IN: IP local_client_ip > remote_public_ip: ICMP echo request, id 517, seq 1, length 64
15:38:39.245071 ipsec0, OUT: IP local_public_ip > remote_public_ip: ICMP echo request, id 517, seq 1, length 64

But i can't find any thing in the other end.
