I have a m0n0wall (home net: 192.168.0.0/24) and a Suse Enterprise Linux 10 SP2 server (remote net 192.168.7.0/24).
I have succesffully created an IPSEC tunnel between the subnets. However, the gateway's are unable to ping a host through the tunnel unless I use "ping -I x.x.x.x z.z.z.z".
I sort of understand the problem, according to this: http://www.freeswan.org/freeswan_snaps/CURRENT-SNAP/doc/adv_config.html#multitunnel
I am unable to find a proper fix after trying what is suggested. I am mostly interested in having the SUSE system access hosts on the home subnet.
