I have a router to the internet on one side attached to ed0 and another small network on the opposite side attached to ed1. I can ping either side when logged into the gateway machine, but cannot get the machine to forward packets between the interfaces (i.e. can't reach the inside network from the outside or the outside from the inside network). ed1 is setup as ifconfig ed1 xxx.xxx.xxx.80 -netmask 255.255.255.224 ed0 is setup as ifconfig ed0 xxx.xxx.xxx.81 -netmask 255.255.255.224 gateway="YES" in the sysconfig. Default route is set and can access machines on the net so it's getting through the router (xxx.xxx.xxx.94) and I can access the xxx.xxx.xxx.70 machine on the inside network (both of these from the gateway bsd machine itself). Maybe without a complete reprogram of the router (sorry no way it's owned by my provider) I just can't do it but it would be very nice if I could. Any ideas greatly appreciated. Email or post. thanks all Jim
