I want to forward all connections on a port to another box on the

I have little experience with iptables, and I am currently not using
it at all on this server, so I will need to setup a small iptables
configuration from scratch including any required setup before
whatever command is needed to do this.
This will all be in the same network and not actually be going across
interfaces...the client, server, and otherbox are all located on the
same internal network.
I am sure this is probably easy for someone what really knows what
they are doing.... AND...I have been reading as much as I can on
this, and all the examples I have found via extensive google
searching all deal with the apparently much more common case of
forwarding incoming connections on a external facing network
interface to a different port for a different IP on an internal
facing interface, ala firewall router. And that just does not apply
here. I kinda thought maybe what I wanted was a variation on that
and I tried some different things but none of them worked.
Any help?
Hello,
Please try:
iptables -t nat -A PREROUTING -s your-network -d server -p tcp --dport
-j DNAT --to-destination anotherbox:9000
sorry, I missed the port string.
should be:
iptables -t nat -A PREROUTING -s your-network -d server -p tcp --dport
5000 -j DNAT --to-destination anotherbox:9000
