Note to anyone just looking ...
Normally clients are not involved! The client gives you a
keyboard/display on the SERVER, and the SERVER access the internet and
the following discussion is not relevant at all
-------------------------------------------------------------------------------
I missed the pre-amble, but here is some info:
RedHat 9 does not port forward like this. You need to
echo "1" > /proc/sys/net/ipv4/ip_forward
Other systems should and may work with the FORWARD argument.
Your thin clients will not be able to access the internet unless you
have specified a gateway to them and unless you are masqurading on your
server (unless you have real IPs to waste, and are using them).
So step 1: make another box access the internet.
step 2: gateway the thin clients
step 3: it works.
For me my clients are on eth0 as a trusted network
eth1 is firewalled, but allows free
ESTABLISHED,RELATED incoming to the clients.
My clients use ssh to update the server SQL DB. (card swipes)
