Hello, I am trying to play BF2 online from my LAN using 2 PC's (my girlfriend) & 2 bought original BF2 CD's with EA patch 1.4. I have added all ports to both computers, disabled NAV. Both PC's will play fine online with my internet connection connected direct to 1 PC only not through the router. When I try to connect via my LAN router, with either PC, I always loose my connection within minutes on either or both PC's even if I only use 1 pc, it says "check your network connection". I am using XP PRO & XP Media Editon, 10mb NTL connection with there standard NTL cable modem, Belkin 4 port router. In my router settings, to allow those ports through my 2 PC's I can only see "virtual servers" where I can add those ports & am unsure if this is correct.

In the add box it lists many games but only lists Battlefield comunicator which I have added without success. I have added those ports (client & server) for iver or both PC's but the loose connection problem is still there.

I would be very gratefull for any help & advice anybody may be able to give me & be forever in your debt, hanks for your time/help

Hi hictor,

The virtual servers configuration relates to diverting traffic originating from the outside world into your network, not the other way round.

Here's a worked example:

If someone with a web browser attempts to access your firewall's external (public) IP address, the firewall will reject the connection.  That is its default behaviour.  If you happen to be running a web server on your internal (private) network, and want that server to be available to the big bad world, you would create a virtual server in the firewall's configuration, and use it to divert traffic to port 80 to the server's internal IP address (192.168.x.y).  Now when someone plugs your public IP address into their browser, they are able to access your web server.

A well-behaved NAT firewall will allow traffic that originates from the inside to go out, and will allow replies to that traffic back into your private network.  It is for this reason that you don't have to open up holes in the firewall to be able to web browse from your internal network.

Your firewall really shouldn't be behaving the way it is.  I have seen instances where a firewall will randomly reject traffic that is part of an existing conversation.  In those cases, a firmware upgrade fixed it up.  Have you tried the latest firmware for this router?  And, to ask an obvious question, have you spoken to Belkin or your ISP's tech support?


Max.
