If you would want an internal machine to do any service via linux, you can
make
use of ipchains. Do this also, echo "1" > /proc/sys/net/ipv4/ip_forward but
when you do this, make sure you put it in your rc.local. Or if you're using
redhat, say TRUE to FORWARDING in /etc/sysconfig/networks. By the way, you
also have to recompile your kernel to support IPMASQUERADING. I guess,
it's precompiled with the default kernel.
If you would want your internal machine to be seen outside, PUBLIC, you
must recompile your kernel too with IP-Forwarding support. And that's the
time you're going to use ipmasqadm.
Use
- redir if it's 2.0.x kernel
- ipmasqadm if it's 2.2.x kernel
- i don't know with 2.4.x kernel
---hope this helps
Neil
