[nos-bbs] No network connectivity

[Doug Kalish]

You were right.  The current Mandriva distro blocks a lot of incoming stuff
and I couldn't ping 109 from the lan.  But I opened up the firewall
completely, the lan pings work now and I'm still not able to resolve
192.168.0.109 from jnos...


Thanks for your continued help on this, Bob.

Your tunnel is working otherwise you can't ping jnos from the linux side

Is no firewall rule in linux blocking it?
A lot of incoming stuff maybe blocked by default in the latest distros.

Can you ping your machine at its ethernet ip  address (192.168.0.109) from
another machine at your lan?
