Sander,
There are known problems with the NE2000 on every platform. Basically, it was a "standards" card that never followed the standards. For $15, you can go to any major computer store and pick up an SMC or Linksys card (I prefer the SMC) that is PCI and 10/100. The SMC is recognizable under all versions of Linux, and should not give you any problems.
Also, you do NOT have a static IP address. The very fact that your ISP is providing you an IP address by DHCP says they could give the address to someone else at any time. If, on the other hand, they gave you an address to type in, that IS static. You also need to look at the IP address a little closer. If it starts with 10. or 192.168. or 172. there is a VERY good chance that these are private IP addreses being routed through the ISP's gateway. This means that you'll never be able to reach the server from the outside world, and if you attempt to send e-mail to ANYONE at AOL, it will be rejected. Also the DHCP address you receive is NOT registered as a named server, so you still won't be able to send e-mail to anyone at AOL.
