Ok.. now when you say "ifconfig fxp1" is that the hole line or is it more like 1) "ifconfig fxp1 inet 192.168.1.1 netmask 255.255.255.0" or in /etc/rc.conf 2) ifconfig_fxp1="inet 192.168.1.1 netmask 255.255.255.0" Also has the card more than 1 transiver? Depending on the network card this may the problem. Could you try the option 2) for /etc/rc.conf? Do you get the same error message? The 1) may be flawed since I can't test it and it's been a while since I used ifconfig that way. Have you tried a diffrent network card? Same result? The rest of the layout and intentions looks fine.
