--------------ED8A790389787DDED75D4CDC Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Hello. I'm having some problems setting up a multihomed machine and was wondering if someone could point me in the right direction. I have a FreeBSD box with 2 ethernet cards. One card, rl0, is connected to my cable modem. The other card, rl1, is connected to a Win2000 box. The goal is to have FreeBSD act as a firewall for the Win2000 machine. I have set the IP address of the internal network card (rl1) to 10.0.0.1, and I have the IP address of Win2000 set as 10.0.0.2, with a gateway of 10.0.0.1. The problem I'm having is, I can't get Win2000 to do anything to try and connect to FreeBSD, it won't even do a ping of the FreeBSD machine. From FreeBSD, I can get on the internet, and ping Win2000, but, Win2000 won't connect to anything. I've read quite a few howtos on natd and setting up a firewall, but, I can't figure out why it's not working. Just from looking at the Win2000 settings, it appears it's set up right, so, I am wondering if I'm doing something wrong in FreeBSD. Below I've included the output from ifconfig -a, netstat -rn and netstat -in. Any help would be greatly appreciated.
