Heres my problem in a nutshell. Ive got about 6 486's all running different flavors of linux(Mandrake,FreeBSD,Slack,redhat,SUSE,Mandrake Corp) and ive also got a 800mhz box runnin windows 2000 Advanced Server and a 650 box runnin windows 98 and a 1.2ghz runnin advanced server. Ive got a linksys router connected to my cablemodem and a cisco hub connecting all the puters. The only way i can get out to the internet is using a linksys NIC card. if i use a 3COM NIC i cant get an IP, and if i program a static IP i cant route. This happens in all the computers with all the OS's. Initially i thought it was the router til i replaced it and found the issue on 3 routers. is there some way to get my linux machines access to the internet with the 3COM NIC's i have?

Hi,
Firstly, do these boxes talk to each other happily with the 3com cards - i.e. are the cards working under linux at all ?
If you leave the defaults, the router's dhcp server would be active and should configure the clients on the 192.168.1.0/24 subnet, i.e with addresses in the range 192.168.1.2 - 192.168.1.254 (mask 255.255.255.0). What do you get from a '/sbin/ifconfig eth0' on a box with a 3com card ? Does it show a valid lease in the above range ? When you tried a static IP address was it in this range ?

Forward and masquerade. I assume you are
using one of the windows machines as your
gateway/router? Configure NAT, get a basic
packet filter set in place and then start routing.
That is all there is to it unless your linux
machines are totally broken and this problem
has to do with no network connectivity anywhere from these machines.
If you are using a linux machine as a gateway/router, then you need to verify
that you have the tools you need to do the
job(ipchains/iptables) and that you can connect normally.
Alternately you could run a proxy from the
gateway machine for web browsing and whatever
else the proxy set can provide for the platform you are using.
Please give more info in the future regarding your layout-I am just guessing here.
