I am almost certain I know the answer to this but I thought this would
certainly be the place to ask to be sure. Since I am far from an expert in
this area.
Here's my problem.....
I have a cable modem that is connected to the uplink port on my hub. I then
have two computers connected to that hub. One that can log onto road-runner
and one that I want to proxy through that machine to road-runner. I could do
this on NT with Wingate but I would rather not use Windoze anymore.
Both machines pull their IP's from the cable modems DHCP server, and as such
they are on the same net. Which is good or else my Samba wouldn't work well.
The problem is I setup IP Masquerading according to the how-to. Compiled all
of the options into my kernel. And it even appears to be partly working. ie.
when I type ipchains -M -L I do see connections from the second machine out.
hwoever nothing gets back to it. I suspect it is having trouble forwarding
from one net back to a computer on the same net. ie Forwarding 23.23.23.22
through 23.23.23.21. Is this the case or am I missing something? I am
running
Redhat 5.2, kernel 2.2.3, the NIC is a 3c509, the CPU is an AMD K62-350 and
the
system has 128MB SDROM.
If this is the case would it help the situation by removing the hub, plugging
the cable modem directly into the NIC in 3c509. Then Installing another NIC
(I
have an Intel EtherExpress laying around) to go to the other PC on the 192.168
net.
Before I go ahead and do that (I've never installed 2 NIC's on Linux before) I
want to be sure it is the likely solution to my problem.
Thanks in advance for any help anyone can give me.
Joe
