Details are in the archives, b.t.w. Nonetheless I take it you mean something like: ifconfig_ep1="inet 212.187.0.39 netmask 255.255.248.0" #used to be #ifconfig_ep1_alias0="inet 194.134.130.170 194.134.128.1 netmask 255.255.252.0" #according to some: ifconfig_ep1_alias0="inet 194.134.130.170 netmask 255.255.255.255" #ifconfig_le0="inet 194.134.130.170 netmask 255.255.252.0" #defaultrouter="10.0.0.10" #defaultrouter="194.134.128.1" defaultrouter="212.187.0.1" #static_routes="euronet" #route_euronet="194.134.0.0 194.134.128.1" The only difference is that a -1 netmask results in less ARP failures. Anyway, I think it has been written to facilitate aliassed addresses within the same subnet. I.e. all having the same gateway. The above is an unforeseen case and that it works at all is a compliment to the coder(s). Mine is probably a special case, and temporary to boot. I can live with the: ... arplookup 194.134.128.1 failed: host is not on local network arplookup 194.134.128.1 failed: host is not on local network file: table is full file: table is full ... until the time I can do without the alias. Apparantly, so can FreeBSD. It has been 41 days since the last CVSup <g>. Having tested most, if not all, permutations possible in the config above by commenting and uncommenting appropriate sections; not to mention the manual fiddling with routes, ifconfigs and ARP tables I do feel justified in pointing out that it might very well be caused by having an alias on a different subnet.
