Original setup: one subnet with PCs and MACs. PCs and MACs able to browse for servers/services (like would be expected).
Now: PCs and MACs split up between two subnets ("added a new subnet"). PCs function normally but MACs can not browse (MACs do have TCP/IP connectivity and can find what they need via connecting to the IP but not by browsing).
Assuming it is something with my helper command on interface. Any ideas?
