Port Forwarding is usually done using the router so it will be the same for windows and mac users.

 * YOU DO THAT ON YOUR ROUTER ! —Preceding unsigned comment added by 83.131.61.102 (talk) 12:36, 25 December 2007 (UTC)


 * I'm no expert, BUT, I am a an unreliable source. You're best bet is getting a text book or going to college to learn this stuff, as I found that regardless of thinking you know certain things or the like, unless you have papers stating other wise, you apparently, according to standard or up-to-date sources, don't know anything, just as I don't know anything. It's quite funny. So go eat a bag of chips and just go to school. If you are still reading though, and want to know what my thoughts are on this matter, then this is what I have to say.... You do not necessarily need a dedicated router to perform NAT, although this is the most common implementation. If you have access to raw sockets (which Windows does not), you can mangle IP packets.  This can be done on most Unix/Linux/GNU based OSes.  If you use Ubuntu, for instance, it is possible to do NAT directly from your workstation (using netfilter/iptables in the output chain).  This is generally used if you have more than one NIC and you can use policies to NAT to various addresses.  You can argue that the workstation is now acting as a router, but you can also argue that a router that is using NAT is acting as a firewall, so...


 * If something is performing port forwarding then surely it's a router. It can be hardware or software. It can be dedicated or multi-purpose but it's still a router. It might happen to be a PC running linux or it might also have firewall features but it's still a router. DarrenW (talk) 15:30, 23 July 2010 (UTC)

UDP relay
I'm under the impression that UDP relay and port relay are synonyms for port forwarding. These terms do not come up in a Wikipedia search but they do come up in an internet search. I'd be happy to create some redirects if this is so. --Kvng (talk) 00:42, 2 March 2011 (UTC)
