ddwrt router portforward issue with source net

Hello everyone

my router has ddwrt firmware installed its a dlink dir615 but when i port forward there is an option that says source net i have read that you should leave it blank to make it work but for some reason it wont work 100%

if i check open port tool the port i'm forwarding says open but when i update in cs studio it shows only a hand full of servers and no clients if i switch to my other dlink dir615ddwrt router which doesnt have source net on it all clients conect and all servers so it must be something to do with sourcenet
if anyone can resolve my issue i will donate £5 to linuxsat

thankyou

Thanks ten but the router has ddwrt installed my main intension is to be able to use 2 modems wirelessly linked but in order to do this i have to get port forwarding working 100%

i've looked round for a different revision firmware but cannot locate one guess its time to give up lol

have a look here mate: Router Database | www.dd-wrt.com

thanks mate thats were i got it from cheers anyway

not sure they will work with this router its a D-Link DIR-615 D4
dont want to flash it with the wrong firmware

tried to put stock on a while back but it wont flash think its because i cannot find the d4 revision software

thanks mate tried that but it failed thats what seems to happen when i try stock dont no why ?
