Title: Map internal IP -> External IP
Post by: skogmannen on April 13, 2010, 09:14:54 AM

Hi everyone

I guess this should be about the simplest thing to do, yet I'm still not able to do it...

I've got a DFL-210, 5 public IP's and I want to map one of my internal IP's to the external, to allow all traffic (from my internal IP out on the Net) on a certain port (9670). After reading a lot of howto's and PDF's, and trying maybe a time too many, I give up. I hope someone here can give me a simple answer.

Internal IP: 172.16.37.55
External IP: xxx.xxx.20.211
Port: 9670


Thanks, Skogmannen

As i understand, you want to make static (symmetric) NAT. It's possible with SAT

SAT lan/72.16.37.55 wan/all-nets yourservice-tcp-9670 (SAT: new source = xxx.xxx.20.211)
Allow lan/72.16.37.55 wan/all-nets yourservice-tcp-9670

Of cource, this rules should be upper than lan_to_wan rule folder.
