Question about playing behind router not hosting !

[unbonami]

Well i have ADSL :) and a "nice" SMC router:

Barricade Broadband Router
SMC7004VBR
FIRMWARE version 1.23

(has Universal Plug and Play)

Problem is that when i play on a server and my brother wants to join another server i get disconnected. But some times it works great I can play on server 1 and he on server 2. Also, most of the time we play on the same server and somtimes he just can't join. It's written: Retrying 123.123.123.123 4 times before time out!

So, how do i fix this ? Some friend has a D-Link router and he can have 5 clients behind the same router with no prob.

i'm just a silly newbie come here looking for assistance myself; but in my search for an answer to my problem i may have found a solution to yours: each of your half-life clients need to use a unique port. normally, HL will chose a port on its own. this is why sometimes you guys can both log on (clients are using different ports), and other times you can't (both clients tried to use the same port).

to prevent the port "conflict" from occuring, you need to specify a unique client port for each version of HL running behind your router. in order to do that, add +clientport 2700x to the shortcut's target properties, where x is a unique number.

for example, on your machine, the shortcut target may be:

E:\games\halflife\hl.exe -game cstrike -console +clientport 27004

and on his it would be

C:\halflife\hl.exe -game cstrike -console +clientport 27005
