ipsec tunnel


I've been trying to get a vpn tunnel set up on an OBSD 3.6 box for the last few days. Everything seems to be working fine, except that the returning packets from the tunnel get lost. -> obsd (static ip) -> internet <- sonicwall (static ip) <-

The tunnel is up and I can see the ping traffic come and go.

# tcpdump -i enc0

10:46:19.761192 (authentic,confidential): SPI 0x00005001: > icmp: echo reply (encap)

# tcpdump -n -e -ttt -i pflog0 host

Dec 29 10:48:08.215057 rule 15/0(match): pass out on enc0: > icmp: echo request

Dec 29 10:48:08.226373 rule 14/0(match): pass in on enc0: > icmp: echo reply

Any suggestions?
