Battlefield 4 Ports

To a little more clear, These ports they provide seem to be the OUTBound ports required to play.  I suspect the INBound ports that are typically configured in the router may be in this list somewhere but it would be nice to know which ports are which.

You DO NOT need account for both source and destination in most modern firewalls.  Context Based Access Control dynamically opens inbound ports that are associated with outbound sessions.  What needs to be known is which ports are outbound and which are in.  On the source computer it is EXPECTed to see a random port >1024 used.  Most protocols work in this fashion.  They will pick a random unsed port above 1024 to connect to a specific protocol specified destination port like tftp on 69 or ftp on 21.

Some firewalls require (or your security policy does) that outbound connections be filtered.  Most home devices do not do this.  SOHO devices allow all outbound traffic and only filter on the inbound leg.

So in short, dont confuse OUTbound ports with INBound ports.  Dont expect to see port xxx connecting to port xxxx.  You will however see plenty of port YYY>1024 connecting to XXX.  This is normal.  Thus we need to know which ports if any EA wants us to open to our computer inbound (Hopefully none!!!!).

Thanks!
