I added the lines
ifconfig_fxp0_alias0="inet anotherserverip netmask 255.255.255.0"
ifconfig_fxp0_alias1="inet anotherserverip netmask 255.255.255.0"
to rc.conf but haven't rebooted, I'm a bit nervous that something's not
quite right. 

When I do:
ifconfig fxp0 inet myextractip netmask 255.255.255.0 add
I get the error:
ifconfig: ioctl (SIOCAIFADDR): File exists

I get the same error if I run it:
ifconfig fxp0 inet myextractip netmask 255.255.255.0 alias

What am I missing?

Thanks,
