This is the setup: The firewall PC is running FreeBSD 4.4 with the default 'simple' firewall running. There are two ethernet cards in it, one at IP 206.147.211.9 talking to the outside network. The other ethernet card is using IP 10.0.0.1 and is talking to an internel network of two PCs. One PC is running FreeBSD 4.4 and is at IP 10.0.0.2 and the other PC is running Win98 and is at IP 10.0.0.3. Both are using 10.0.0.1 as the default gateway. If both machines are plugged into the network and running everything seems to be working fine. However as soon as I shut down the Win98 box or unplug it from the network, the FreeBSD machine can't communicate out of the firewall anymore. Plug the Win98 box back in and it starts working again. Any suggestions? TIA -- Tom Greenwalt (F.O.E.)
