== Pre-face ==

EA says the following ports are used by BF2, But the list is suspect for several reasons. The original list was published in a community news letter on EA's official BF2 page, and was a hode podge of ports, now I can't seem to find that community update again, if anyone bookmarked it please let us know the url<br>
Here is a tentative list:

{| border="1" cellpadding="2"
|+'''BF2 Server Ports'''

|-

I've done some research on ports used and such, please contribute on the [[What Ports]] page if you got updates/erratas

== Firewalling Your Server ==

This is from the readmeserver.txt

FIREWALL

The use of a software firewall on the server is not recommended,
as it can adversely affect server performance and the overall
gameplay experience.

Ignore this. Running a server on the internet without a firewall is like <code>insert favourite allegory about being sodomized here</code>

=== How to firewall your server ===

Two ways to do this:

;External firewall:You have a machine that all traffic has to pass through to get to your server (my favourite)
;Local Firewall:You are running a firewall on the same server as you have the server (uses local CPU,so not the best way)

We will NOT go into the rigamole on HOW to set up a firewall for your system here, lots of other sites cover this.
What we will attempt to cover here is the specific rulesets that are needed for a BF2 server to work properly.
=== External Firewall ===
We need more info here folks!
=== Local Firewall ===
==== Linux Iptables ====
This ruleset allows my server to be seen in the server browser list, people can join it AND use VOIP
Note that this is a stander server, only one BF2 server on the machine, and no hank panky with ports
used and such
iptables -A <ChainName> -m udp -p udp -m multiport --dports 29900,29901,29902,29903,29904,16567,55125 -j ACCEPT
iptables -A <ChainName> -m tcp -p tcp -m multiport --dports 4711 -j ACCEPT
iptables -A <ChainName> -m udp -p udp --sport 29910 -s 207.38.8.27 -j ACCEPT
