[K12OSN] LTSP server with 3 NICs?

I agree, and that's how I've done it.  Matter of fact, in our schools, I 
have to, given that our thin clients may be spread out through the 
school.  VLANs save my hiney then.  I can just dedicate one VLAN per 
thin-client segment, and boom, I'm off to the races.

Layer 3 (aka "routing") would be done by the K12LTSP server for anything 
on the thin-client segment, so that's taken care of.

Do you GNU <http://www.gnu.org>?

antivirus protection!
