I have a server running on CentOS that sits being another firewall. I want to forward a certain ports to another server, but only for a handful of addresses. Can anyone assist with an example rule of this?
For example, let's say I wanted requests from 24.83.77.24 and 63.47.50.16 on port 10001 to forward to internal server 192.168.1.15
All other requests for THAT port would be rejected or dropped.
Anyone willing to give me an example rule that would allow this to be forwarded?
I appreciate any help.
Thanks, James
Well, you can do it like this in the *nat table: -A PREROUTING -d 63.47.50.16 -p tcp -m tcp --dport 10001 -j DNAT --to-destination 192.168.1.15
