Why not: ifconfig fxp0 inet 200.46.204.2/24 ifconfig fxp0 inet 200.46.208.2/24 alias ifconfig fxp0 inet 200.46.204.10/32 alias ifconfig fxp0 inet 200.46.204.5/32 alias ifconfig fxp0 inet 200.46.208.254/32 alias ifconfig fxp0 inet 200.46.208.251/32 alias ifconfig fxp0 inet 200.46.208.244/32 alias so on ? With the only fxp0 interface
You can freely add or delete all /32 addresses while not 200.46.204.2 and 200.46.208.2 > So, right now, I'm using both fxp0 and fxp1, with fxp0 handling the > 200.46.204.* C-class, and fxp1 handling the 200.46.208.* C-class, so that > I can easily add/remove as required ... > > ---- > Marc G.
