[Openswan Users] Subnet to Subnet problem

[Benjamin Minshall]

Hello,

I have an openswan tunnel almost working between two linux gateways.  Kernels are 2.6.27.x.

~# ipsec --version
Linux Openswan U2.4.6/K2.6.27.2 (netkey)


A |--- priv ---| G1 |--- internet ---| G2 |--- priv ---| B

I can ping from host A to the private interface of G2 just fine, however pings from A to B do not make it.  Pings from G2 to B work.  I used tcpdump to confirm that the ESP packets are arriving at the public interface of G2, however no packets are leaving the private interface of G2; as though they are lost at G2.

Do anyone have any suggestions for fixes or further troubleshooting?  Thanks.
