I'm not sure if you've already done this, but here are some notes:
vpn1 needs to be the default gateway for lan1 and same for vpn2 and
vpn1 needs to have the following route:
route add -net 192.168.2.0 netmask 255.255.255.0 gw <public IP of vpn2>
and vpn2 needs this:
route add -net 192.168.1.0 netmaks 255.255.255.0 gw <public IP of vpn1>
Then it should work. I hope :)

HB> lan1 192.168.1.1
HB> vpn1 eth0: connects to Internet
HB> eth1: 192.168.1.254
HB> ssh tunnel with ppp
HB> vpn2 eth0: connects to Internet
HB> eth1: 192.168.2.254
HB> lan2 192.168.2.1
HB> the route command that I run on vpn2 is
HB> /sbin/route add -net 192.168.1.0/24 gw 192.168.1.254
HB> when I check the routing table the relevant line is
HB> 192.168.1.254 * 255.255.255.255 UH 0 0 0
HB> If I try and ping lan1 from vpn2, it tries to go out over the Internet.
HB> Same sort of setup on vpn1 with the same sort of results.
HB> I know it must be a simple command, but I can't figure it out.
