I am having a problem with getting my NIC card working correctly. It
seems to timeout when nothing is being pinged. I mean, at first I can
connect both ways but after some time of inactivity I could only ping
one way. On the server with the NIC an message at the promp says
"ip_tables: Netfilter core team ip_tables: (c) 2000 - 2002 Netfilter
core team"

Does anybody know what this means?
