Another QUICK question:
ALL of my ports in ALL VLANS are "U"ntagged.
VLAN 1 - U - Ports 1-10
VLAN 10 - U - Ports 1, 11-25

What have you set for the PVID defining the VLAN where incoming frames to port 1 will be assigned to?
This looks to me like an asymmetric VLAN config - something Netgear does not support at all.
