Local Port Forwarding

Locked

Hi,

I need to map local port to another local port.

For example, access to port 80 will be forwarded to 8005.

Sounds silly, but this is because my network admin can not open access to port 8005 on the firewall, only to http service which in on port 80. I can not change the port 8005.

It depends a little:

If you have linux (iptables netfilter is
assumed) and want something remote incoming to
port 80 map unto port 8005:

iptables -t nat -I PREROUTING –dport 80 -m
state –state NEW -p tcp –sync -j DNAT –to
127.0.0.1:8005

You can of course add -s and -d to it to only
accept from certain sources to certain
destinations -i for the incoming interface.
You can change 127.0.0.1 to point to any host on
your network.

Hope this helps,
