Hi
I'm trying to install a new network card(CNet) on a Mandrake 9.2 system that otherwise works fine. but cant get the new card to connect to internet(the old one works fine). now I have two network cards since the old one cant be removed. I've used the drakconnect wizard, and it says the new card state is up and it gets an ip number from my router's(dlink604) dhcp server, but no internet connection I have no idea what to do now..

check network configuration by the followings:
#ifconfig
#cat /etc/resolv.conf
#route -n
u can post the outputs here, so we will be able to check it.

thanks for the answer
here's the outputs from those commands: (eth1 is the new card)

Everything appears to be configured correctly. Can you ping the router? Are you running a firewall?

it works then i choose 'no firewall', thank you
but why does the older network card work with the firewall?
Is it neccesary to have a firewall? I use the computer as a server.
What's the difference between the 'firewall' and 'internet security level'?

maybe i can try to answer my own question. i asked a friend and he said i probably wont need at firewall since i have the router(dlink) where i can setup which services i would like to allow the internet to connect to.
thanks for all help
