Hi folks.
I've given up on openswan because it won't work though my ADSL router.
I've now got a very simple ppp-over-ssh VPN working using the following script
/usr/sbin/pppd updetach noauth passive \
pty "ssh $HOST -P -o Batchmode=yes /usr/sbin/pppd nodetach notty noauth" \
$LocIP:$RemIP
I'm using 192.167.127.1 and .2 for the VPN
My local LAN is 10.6.0.0/16 and the remote is 10.1.0.0/16
The VPN works, and from each end I can ssh to the remote end using either it's
192. or 10. IP address.
On each gateway, and on the test hosts on each LAN I have set up the
appropriate routes. On each gateway I have enabled IP Forwarding by running
sysctl -w net.ipv4.ip_forward=1
and made it permenant by editing /etc/sysctl.conf. I even rebooted to make
sure.
However, I cannot get anything to work except gateway to gateway. Anything
behind the gateways cannot get past their local gateway.
Anyone know what I've missed?
I guess its normal not to pass because the next gateways dont "know" what 10.x/192.x ips are.
I think either you have to export those IPs to the next gateways either you enable nat
for each VPN, smth like iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE (fastest
way) where eth0 is your interface for internet.
