IP Masquerade problems in RH Linux
Posted on 2002-03-31
I have a RH Linux 6.2 box, configured to be an Internet gateway/firewall. I have the default IP Masquerading modules that came with 6.2. I dial out to the ISP using "ifup ppp0".
I have five machines that can access the gateway and the Internet (one/two at a time - slowly). My XP, w2000, and NT4 boxes all reach the Net through the gateway just fine. I have downloaded ISO CD's from them too.
My problem comes with the RH 7.2 server and RH 7.2 workstations. I can "surf" the net (through the RH 6.2 gateway) but frequently lock the gateway up. I then have to "ifdown ppp0"/"ifup ppp0" the gateway to get the 7.2 boxes to continue on the Internet. I can't download any files over about 50KB (via http) without locking up the gateway.
I need to stop this RH7.2 to 6.2 lockup problem.
