I try to realized a VPN between 2 LAN using 2 for gateway OpenBSD 2.9.
The problem:
on host W98 on 192.168.20.0 (the same net of the gatewayB) I do a ping on
host W98 on 192.168.10.0 (the same of the gatewayA), but I don't receive the
echo reply. Note the default Gateway on all W98 machines is the internal
interface of the gatewayA for Lan 192.168.10.0 and gatewayB for Lan
192.168.20.0

Logged on gatewayB I can se with:

    tcpdump -i enc0

...data..(authentic,confidential: Spi 0x45A8428E: 192.168.20.4>192.168.10.4:
icmp: echo request(encap)

and
    tcpdump -i external_interface host gatewayA

...data... esp gatewayB > gatewayA spi 0x45A8428E seq 1  len 116

The same thing I see on gatewayA.

Please Help Me.
Sorry for my English.
