I have two ethernet cards going. I wasn't able to hook up my cable modem to a hub and have everthing work , I guess because it has something to do with mac address of ethernet card . It works nicely now with natd and two ethernet cards. I just started natd -d -interface ed0 in /usr/local/etc/natd.sh In my /etc/rc.conf file I have it configure my ed1 card for ip add 192.168.10.1 etc. My ed0 card is the card hooked up to the cable modem I have this device remmed out only thing I have is network_interfaces="lo0 ed0 ed1" #ifconfig_ed0="inet ...etc ifconfig_ed1="inet 192.168.10.1 netmask 255.255.255.0" also have gateway_enabled="YES" Bryce Newall wrote: > > On Thu, 15 Oct 1998, Stephen A.
