It's been a while, so bear with me.

You assign multiple IP addresses to your ethernet card:

ifconfig eth0 192.168.128.1
ifconfig eth0:1 192.168.129.1
ifconfig eth0:2 192.168.130.1

and so on. You can also do this through your distro's network configuration.

Then in smb.conf you tell samba to listen on those interfaces.

I think that's it. You end up with one workgroup that different subnets
can see.

If you want different workgroups I think you can run multiple samba
daemons with different interfaces set up and different workgroup names.
You'd probably have to separate out all of the volatile files like *tbd,
but I can't say. As long as the IP addresses are different this should
not cause problems.

ISTR I had to do some voodoo with wins forwarding but that may be because
I had remote servers connected via VPN.

Not written down in any detail but perhaps others can fill in.
