Port Forwarding - Refer Traffic From Port 8000 to another internal IP

deepGC · 10-10-2015, 10:56 AM

Hi,

I am running two sites/accounts on one server,

Site 1 - 1.1.1.1
Site 2 - 1.1.1.2

I receive a lot of traffic on port 8003 on site 1, that I want to redirect over to site2.

Hence 1.1.1.1:8003 - in essence, then becomes 1.1.1.2:8003

Is there anyway I can do this in csf, is this even possible?

Please note, that it is just port 8003 on site 1 that needs redirecting internally, the other traffic is fine.

Thank you

If you'd rather not tinker with your firewall directly, rinetd is a tcp redirection server that's pretty easy to set up.

Hi,

I've installed rinetd, but struggling to get it working.

The public IP for site one is 78.129.251.122, the public IP for site two is 78.129.251.125, the port in question is 8044.

I tried the following in rinetd.conf:

78.129.251.122 8044 78.129.251.125 8044

But receive the following message:

rinetd: couldn't bind to address 78.129.251.122 port 8044

Managed to do this via. redir:

redir --laddr=78.129.251.125 --lport=8044 --caddr=78.129.251.122 --cport=8044
