Hey all,

Just wondering if anyone can offer some suggestions to my problem. I have slackware 9, running iptables for my firewall rules. I have a LAN on eth1, with the class C range 192.168.0.X, and eth0 is my gateway to the net. I have a cheap 4 port hub, that may indeed be the cause of my troubles.

Issues:

When I set my internal machine to a static IP on the class C range 192.168... things seem to work OK .. for awhile. As soon as I get any collisions on my hub, my internal machines lose connectivity to the internet, but they can still see the gateway 192.168.0.1 and the IP for eth0 from my ISP. Nothing past that. This lasts until well after the collisions have stopped. Either I must wait until it decides to let me through again, or lease an external DHCP address for that machine, then switch back to masquerading.

Any suggestions would be greatly appreciated...

Cheers.

Hmmm.... I'm not sure what the problem is but is it possible to use DHCP all of the time? It's remarkably easy to set up.

Do you mean setup my slackware machine as a DHCP server, or just use a DHCP IP address provided by my ISP? .....

I dont have my linux box setup to hand out DHCP addresses as of now. My problem is when I am doing LAN transfers with Samba, _and_ doing external internet communication, my external connex dies.....

Cheers

Yeah you seemed to say that DHCP seemed to fix it for you temporarily. I run samba, nfs and have an external connection with four computers and I've never had a problem. With regards to DHCP, it's often convenient to have the gateway be your DHCP server so whichever computer is the gateway then that's the one to do it on. I'm not entirely sure if that will fix your problem it was just a suggestion. It does seem to be a little like a hub problem. Can you borrow a hub off someone else to see if that's the problem? If you lived in sydney I might be able to lend you one. I've got heaps.
