same wire, 2 logical nets, linux box has one card listening on both
nets. i want it to fully route between them (because the windows
boxes can't).



linux:eth0		192.168.x			windows / linux
      eth0:1		192.168.y			windows / linux


i can not for the life of me get linux to fully route packets between
eth0 and eth0:1. in the end i had to add a second NIC, eth1.

note that linux clients have absolutely no problem with redirects and
192.168.x subnet boxes have no problem talking to 192.168.y boxes.
windows however apparently needs someone to route the packets.

nope.. (plus my switch seems to get flaky just with plain adaptive
partitioning within the switch, so i wouldn't trust it with anything
fancy like VLAN)

ultimately i want to make the subnets be physically distinct. but
that'll take time. in the meantime i need linux to route packets
between logical subnets - not send redirects.
