I think a bit more clarification is due here.
Based on my own experiences this last week, it looks like there are two \"connections\" needed to play Planeshift.

I know, udp is connectionless, but you get the point.

Anyway, for all of you playing in your local lan with a router/firewall in the middle:

Connection 1: From your PC to Planeshift Server
PC (random source port) --> Planeshift (port 13331)

Connection 2: From Planeshift Server to your PC
Planeshift (didn\'t check the source port) --> PC (port 13331)

You have to allow these two connections in you firewall. Besides, depending on your router configuration, you probably will have to play a bit with NAT (to make sure your public IP port 13331 gets redirected to port 13331 of the machine that is playing.)

This doesn\'t look too right for me, because I heard someone say he was playing with several computers on a local lan, and that doen\'t fit this scheme, so maybe this isn\'t the right set up, but it\'s the only way I\'ve been able to \"play\" so far.

(\"play\" is really an overstatement, since my char moves sooooooo slowly...)

NOTE: If you tried to upload any character and you got linkdead, chances are very hight you won\'t be able to play that character even if you set up your connection right. Just create a new character and enjoy.

Hope this helps.
