The network traffic isn't going to "magically" traverse the machine, FreeBSD has to be told to forward it. You don't describe your network in much detail, so I'll tell you a good way to do it and you can either learn from this or duplicate it exactly. The gateway should have something like this (hypothetically) NIC to internal network IP=192.168.1.1, netmask 255.255.255.0 Modem IP=192.168.2.1, netmask 255.255.255.0 Make sure gateway service is turned on Your home machine (assuming there's no home network, only a modem) Modem IP=192.168.2.2, netmask 255.255.255.0 Set 192.168.2.1 as your default gateway You should now be able to reach any computer your dial-in server can reach. If you've got a home network and another default gateway (such as your ISP) it gets just a little more complicated. In that case, your routing table should look something like this: default your.isps.gateways.IP 192.168.2.1 192.168.2.2 192.168.1 192.168.2.1 You may have to add routing statements manually to accomplish this. You may also have routes to your home network (if you have one), just make sure none of the ip/netmasks overlap or conflict. > The other thing I should mention, is that originally I set up the > Dial-in Service on a WinNT machine and had the exact same problem, > except now I could get from the WinNT machine to the FreeBSD machine > (and the rest of the LAN)! I don't understand what you're describing here. But if you had the same problem, it's like that you've made a similar configuration mistake on both the NT and the BSD machine. > This kinda makes me think it may be my settings on my home machine, > but I have no idea what to do different.

Use "netstat -rn" to see how your routes are set up, if you don't have a route to those other machines, you'll not get to them. -- Bill Moran Potential Technology http://www.potentialtech.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
