This is expected. Only one of those interfaces has a network route so it will be used for all communications to that network. I'm guessing your route to 10.0/16 is via xl0 though I can't say for sure because you haven't provided the contents of your routing table as previously requested (use "netstat -f inet -rn"). If you want two interfaces to be on the same subnet and to provide the broadcast medium for that subnet, you need to bridge them. If you want the ability to alternate between the two connections to the same host, you may be able to use CARP or ng_one2many. -- Brooks > --- =D6zkan KIRIK <ozkan@mersin.edu.tr> wrote: >=20 > > You cannot define same network to more then one > > interface! > >=20 > > As you post below; > > xl0: inet 10.0.1.1 netmask 0xffff0000 broadcast > > 10.0.255.255 > > xl1: inet 10.0.1.2 netmask 0xffff0000 broadcast > > 10.0.255.255 > >=20 > > They are at the same network, so your freebsd > > searchs 10.0.1.2 at xl0. > > You should define your xl1 as inet 10.0.1.2 netmask > > 255.255.255.255 > >=20 > > With Best Regards, > > Ozkan KIRIK > > EnderUNIX SDT@Turkey > > Software Developer > >=20 > > Daniel Valencia wrote: > >=20 > > >Hi > > > > > >from the boot messages, i can see that the network > > >devices are started up properly.
