Network Routing via NIC Aliases

[a.cowan.usenet]

Hi Folks,
I have a situation where I need to route between 4 subnets. I know
it's somehow possible to do this if I have 4 different physical NICs
in an XP box - but is it also possible to do this with a single NIC
with three additional aliases?

I.e. instead of:
NIC1: 172.16.1.1/255.255.255.0
NIC2: 172.16.2.1/255.255.255.0
NIC3: 172.16.3.1/255.255.255.0
NIC4: 172.16.253.1/255.255.255.0

it'd be:
NIC1: 172.16.1.1/255.255.255.0
172.16.2.1/255.255.255.0
172.16.3.1/255.255.255.0
172.16.253.1/255.255.255.0

I'm aware of bandwidth restrictions if I'm only using a single 100Mb
NIC, but this is only required for a last resort emergency measure and
I don't anticipate a high amount of network traffic.

Any thoughts appreciated.

Thanks,
Alistair

This should work if you add the other IPs under the Advanced TCP/IP settings.
On non-server OS's you also need to apply a small registry patch.

Note that this will only route IP's, to resolve names across subnets you
need an additional mechanism, eg hosts, DNS, WINS.
