[CentOS] BQ/CentOS port forwarding

[Richard Veale]

I tried to set up IPtables for it using:

iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 3389 -j DNAT \ --to
10.0.0.100

but the 'to' statement does not seem to work on my CentOS box and every time
I do anything to IPtables my DNS blows up.

Thanks Robert,
I have a Terminal Services Server that will be behind the inside interface,
I need to forward hits on port 3389 eth1 to an IP address behind eth0.

Well it depends on what you are trying to forward  But to turn on forward in

general use this;

/bin/echo 1 >/proc/sys/net/ipv4/ip_forward
