My apologies for not including the rc.conf...but I have;

    ifconfig_fxp0_alias0="inet 208.239.172.50 netmask 0xffffffff"

ifconfig  fxp0

        fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
         inet 204.107.76.181 netmask 0xffffff00 broadcast 204.107.76.255
         inet6 fe80::203:47ff:fe12:3c51%fxp0 prefixlen 64 scopeid 0x1
         inet 208.239.172.50 netmask 0xffffffff broadcast 208.239.172.50
         ether 00:03:47:12:3c:51
         media: autoselect (100baseTX <full-duplex>) status: active
         supported media: autoselect 100baseTX <full-duplex> 100baseTX
10baseT/UTP <full-duplex> 10baseT/UTP

Thanks, though it was a good try...

I also forgot to mention I'm running 4.2r...

cheers,
mikel
