Need help configuring network card

[hoggwild]

I am fairly new to Linux...and I can't seem to get the hang of configuring a network card for a static IP address.

I have a server I'm converting to Linux that resides behind a Linksys wireless router connected to the internet through my phone company. I do have a static IP address from the phone company.

I would like to configure the network card so that it has a static IP address instead of obtaining an address from the router using DHCP. However, every time I try to configure the network card for a static address, I seem to screw everything up, and the server is no longer able to transmit mail over the internet to external addresses (I'm obviously configuring something wrong). If I let the network card obtain an IP address from the router using DHCP, everything works find; however I have to reconfigure the router to route the different ports to the server every time the network IP address changes, which is a major pain.

Is there anyone out there who is willing to help me with this?

I would appreciate any assistance you can offer.

Can you post the outputs of

ifconfig

and

route -nee

when the system is using DHCP and can connect to the internet?
Which distribution are you using?

Falko,

Thank you for responding. I finally figured out what I was setting up wrong, and everything's working now. Took me forever to figure this out.



I'm learning.
