Hi guys,
Those are the ports that should be open on your router/firewall in order to properly connect to DUST 514

Backend communication needs TCP 443 and 80.

Battle server communications needs UDP 20000-21000.

Voice communication needs UDP 12000-13000.

I had a couple of problems getting in to dust one was my stupid fault the other was this problem.
Dust support was Excellent! (Thanks to GM Kiriap, and anyone else who helped ) with their help i fixed my first problem and at least my version of this problem.
Took me a while had to work this weekend but try this.
Open Router, set ip as static, exclude it from you dhcp, turn off upnp, and set up a DMZ for the ip.
open ps3, set the network setting to that ip, and your dns to the router.
restart the ps3 and router then try.
This should remove all problems if done right if you need help with it just post here.
after that you can start turning stuff like upnp on to see if it will still work.
i will ask the GM that has helped me what ports dust uses and will get back to you when i find the ports used so just those ports can be forwarded.

So Stryker you need to get on so you can hear my lovely voice again. I was able to fix the mic issue. Apparently the firmware on my router was not allowing voice chat for dust only?! Kinda weird but when i changed my firmware to tomato and put in the ports now it works perfectly. YAY!
