added port 43391 to TCP/UDP allowed

i use this for locally hosting minecraft servers via the Open To LAN
feature, UDP is required for the Simple Voice Chat mod
sadly this does not seem to work and i havent a clue why, but I am
leaving this port open for now

SVC works perfectly with the Essential mod hosting
