-----------------
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" )
dns_domain_br0="example.com"
dns_servers_br0="pp.qq.rr.ss tt.uu.vv.ww"
dns_search_br0="example.com"
bridge_add_eth0="br0"
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 :(

Bye,
Daniel
