Hi
the load balancing and dont work????
my configuration
OpenBSD 4.0 amd64
lan soekris lan1641, Four port 10/100 Mbit PCI Ethernet board
lan_net = "192.168.1.0/24"

ext_if1 = "sis1"
ext_if2 = "sis0"
ext_gw1 = "2x.x.x.x"
ext_gw2 = "2x.x.x.x"
# nat
nat on $ext_if1 from $lan_net to any -> ($ext_if1)
nat on $ext_if2 from $lan_net to any -> ($ext_if2)
