okay, I have a linux box currently configured as a router (ip chains is installed but set to accept everything) that will become a firewall (once I get the routing down), and while I can ping from inside the firewall out, I cannot ping from outside the firewall in..I shouldn't be doing any sort of IP masquerading, so I'm a bit lost right now...I've done routers and firewalls before, but this is the first one I've done with the 2.2.x series (yeah, really...I'm getting behind the times here)...any ideas one what I"m missing (I'm pretty sure it's somethign stupid at this point) Vinnie -- Reality is a formality, an agreed upon set of lies -- J.D.
