here....i think i know the problem...but i cant find the solution....
I use windows XP SP 2 ...Asus motherboard..
I use integrated Ethernet port (NVIDIA nforce controller) to connect to the hostel LAN and used the same connection
to get internet (using proxy). I played counter-strike without any problem...

Everything worked fine until i took a direct ADSL internet connection...
So i installed a separate ethernet card (INTEX rtl8139D) which i use to connect to the internet...

So now i have two LAN ports ...one for internet and one for LAN...
The problem is...i cant connect to any counter-strike servers created on LAN...
Disabling the internet connection allows me to connect to the cs servers...

I think the reason why this is happening is :
CS is trying to use my internet port to connect to the LAN server....so it is failing...

so how do i specify which port is for internet and which is for LAN...
or i guess the applications themselves decide which one to use...and CS isn't able to do so correctly.....
I use XP...if there is a setting in CS (i searched but i didn't find any) that needs to be changed ...then please let me know...
My internet works...i can play FIFA on LAN ...but only CS has got some problem with it....
