brctl_br0=( "setfd 0" "sethello 0" "stp on" )
config_br0=( "aa.bb.cc.dd netmask dd.ee.ff.gg broadcast hh.ii.jj.kk" )
routes_br0=( "default via ll.mm.nn.oo" )
config_eth0=( "null" )
brctl_br1=( "setfd 0" "sethello 0" "stp on" )
config_br1=( "null" )
This should create two bridges:
br0 gets the public IP and the physical interface is connected to it
br1 can be used to interconnect two VMs without connection to dom0
and the outside world
/etc/conf.d/net is super powerfull, and super bad documented
