[LARTC] Mulitple VLANs containing the same ip subnet NATed on same box

[Geoff Karl]

I know this is not a normal request, but I would like to connect two
vlans into the same box that have the same subnet on them, and then
NAT them out to the Internet.

We don't need to make any connections inbound to them, but only
provide outbound access.

Any suggestions on how to do this?

If I can't do it with routing then I could use something like
user-mode Linux, or other virtualization software.

Thanks,

Geoff
