Alright, I'm using Fedora Core 1. My box is setup as a router for the rest of my network. It has two network cards, one 10 base card connected to a cable modem, and another 10/100 connected to my network switch. I have iptables setup to do masquerading. The problem... Telnet/SSH connections to the machine, from the outside world, disconnect after 5-10 minutes of inactivity. For example, I can have 3 SSH connections to my box, neglect one window for a few minutes, and when I go to that window and start typing, I get a message from PuTTY saying I got disconnected. I've looked extensivly on the net trying to figure out what's wrong and how to fix it. I've come across a couple sites saying that this could possibly be caused by a 'NAT teardown'. I'm new to iptables and NAT, so i'm not exactly sure what this means. I was under the impression that NAT timeouts on CONNECTED connections was like 5 days of inactivity before it would drop. When I cat /proc/net/ip_conntrack, i see my connections, and I see they have very high timeouts. I've looked through the iptables man page, as well as the iptables/netfilter website, and i can't find anything relevent to this. Does anyone know how I might fix this? -Jeremy __________________________________ Do you Yahoo!? Yahoo! Finance: Get your refund fast by filing online. http://taxes.yahoo.com/filing.html
