Unable to NetBoot across subnets with Lion

[AndyBeaver]

Hey guys, For whatever reason I am unable to netboot any of our macs across subnets. i.e 10.0.1.131 is my mac imaging server. If a machine has an ip of anything other than 10.1.x.x it will not net boot. Any ideas?

Is it safe to say this was working with Snow Leopard? Did any IP's change? Did any routing change? Did IP helpers change? More times than not, when it only works locally, it's on the networking side of the world, not server side.

Yes my mistake, the problem was with the IP helpers. This incident reminded me to slow down and start at square one and troubleshoot from there!
