Greetings,
I've been through the IP-Masq howto, and the masq list archives....
I've got a real head scratcher going on my home network. I have a 2
node hubbed 10Mbit network at home. One node is my linux box, RH 6.2
w/ RH 2.2.16-3 kernel RPM with 2 NICs and a RoadRunner cablemodem
one eth0 and the local ethernet on eth1. The second node is a
Windows 98 system. Both are connected to a dumb little NetBus 8 port
10Mbit hub.
I have linux set up with ipchains to IP Masq the internal network to
the cablemodem interface and I run a split DNS system on the linux
system to provide minimal name service for the windows box.
Everything worked fine for several weeks and then the windows box
started developing problems accessing websites, and with having AOL
connections via TCP/IP disconnected randomly and often.
I was using the pmfirewall script to provide the ipchains setup,
trashed that and developed a minimal ipchains setup. That change
didn't help anything. If we attach the cablemodem directly to the
windows system it works fine. Re-attach it to the linux box and it
start crapping out again.
I've tried tcpdumping all traffic on both interfaces on the linux box
and watching things as they happen. It appears that the windows box
makes the initial connection to a website but after a 2 or 3
exchanges of packets, the remote site just stops sending anything.....
Has anyone seen this kind of problem before and can you offer
assistance?
