[lug] routing problems

[Hugh Brown]

I am trying to set up a vpn using ppp over ssh.

I am able to make the connection and the two boxen twixt which is the
ssh tunnel can ping each other on the non-Internet routed interface, but
I can't get them to ping something on the lan side.  So let me try to
illustrate a little better,

lan1 192.168.1.1
	|
	|
vpn1 eth0: connects to Internet
     eth1: 192.168.1.254
	|
	|
    ssh tunnel with ppp
	|
	|
vpn2 eth0: connects to Internet
     eth1: 192.168.2.254
	|
	|
lan2 192.168.2.1


the route command that I run on vpn2 is

/sbin/route add -net 192.168.1.0/24 gw 192.168.1.254

when I check the routing table the relevant line is

192.168.1.254   *               255.255.255.255 UH    0      0        0
ppp0

If I try and ping lan1 from vpn2, it tries to go out over the Internet. 
Same sort of setup on vpn1 with the same sort of results.

I know it must be a simple command, but I can't figure it out.

TIA,

Hugh
