I have a machine, accessible from outside our company, running PPP.
It's local IP address is 10.0.1.29 (the address it gets from PPP).
I also have another machine whose IP address is 10.0.1.3 and also has
an IP address of 192.168.5.88 connected to our local network.
I can get to the 10.0.1.29 machine through an external IP address (which
I won't list here, for security reasons) and from there ssh to 10.0.1.3
and from 10.0.1.3 to the 192 network.
I would like to be able to get right from 10.0.1.29 to the 192 network.
On 10.0.1.3 I set the ip_forard (I forgot exaclty what it is called) to 1
and restarted the network.
192.168.x.x addresses are not forwarded by
routers. They are simply thrown away as private addresses. NOw, you could on
the 10.0.1.29 put in a routing table telling it to send all such packets to
10.0.1.3, but if there are any routers in the way, they may well discard it.
On 10.0.1.29 I did an
ip route add '192.168.5.0/24' via 10.0.1.3 dev ppp0
and
ip route add '192.168.5.0/24' via 10.0.1.3
tried both. It was entered succesfully and showed up in "route -n" but
when I tried from 10.0.1.29 to do for example
ssh -l root 192.168.5.191
Do a traceroute on the ppp0 to see if the packet is going out (are you sure
that 10.0.1.3 is directly connected to 10.0.1.3 via ppp )
Youneed to tell us exactly what the connection topology is.
it wouldn't let me and couldn't connect (though it would work from 10.0.1.3).
Did I miss something, or what else do I need to do?
I somehow got this to work earlier between our 192.168.5 nextwork and
our 10.0.0.0 network where a machine (10.0.0.215/192.168.5.15) was on
both networks, and I set its address (192.168.5.15) as default router
for 192.168.5 networks and 10.0.0.215 for 10 networks.
192.168.5 mask is 255.255.255.0 and 10 network mask is 255.0.0.0
