Ns Server Firewalled...can't "add Server"

<div class="IPBDescription">Almost there, but not quite.</div> I've been working on setting up my NS Server on the T1 I have.

In order to provide protection, I'm placing it behind my firewall as well.

So...

Here's what my situation looks like and the problem I'm having.

External IP -forwarded to- Internal IP...in this case.

204.244.10.164 -> 10.10.100.3

Firewall is setup to deny all port connections that are less than 1500 (on both TCP and UDP), and allow all others. (Including ICMP, for pinging). (I know, it's still fairly open, but I'm still working on troubleshooting this... I know I need 27100-27125 UDP open, and 7002 TCP open...but other than that....)

1) The server does function and it can be connected to, BUT, only by direct connection, GameSpy(can ping), or GameTiger(can ping) (haven't tested others).
2) If you attempt to retrieve a list from inside NS, the server does not show up on list.
3) If you attempt to "Add Server" from inside NS, the server does not show up on list. (using 204.244.10.164:27015)

The server will be running today if you want to try connecting to it to assist me in troubleshooting.

I'm grateful for any assistance or suggestions that you can offer, but I'm outta ideas.

    i'm still a CCNA intraining so to be safe, i don't want to suggest anything about the actual router config.

    but i can say you need ports 6003 and 7002 TCP to be forwarded to the server.

    It appears that you are forwarding everything except ports <1500 to it anyway, so i'm not sure if thats that problem.

    have you tried connecting to the server from home? because HL browser is flaking with my computer too.

    Not a router, just a PIX. I'm open to suggestions, I've also very careful about backing up my config...so I can experiment quite a bit.

    6003 as well eh? Hmm...good to know.

    I can connect to it from home....you should be able to connect to it right now if you tried.

    can you (after careful editing) post your pix config?

    I have a 501, 515 and 525 I can play with to look at it.

    I've never tried firewalling my systems as for me its more trouble than its worth, and it only takes me 15 minutes or so to rebuild everything (I have an image of the HD).

    I have plenty of cisco gear to test things on if anyone has questions (Im a network engineer).

    Fixed now...thanx for advising me of the 6003 port!

    (BTW, if you're having problems with adding a server to your list in NS, uncheck all your filters and try again.)
