Here is the setup:
SonicWALL NSA3600 has WAN on X1 and DMZ on X2 Netgear FS728TP has port 28 plugged into X2 on SonicWALL and port 27 plugged into a production switch Ubiquiti AP's are plugged into ports 1-6 on FS728TP VLAN's are set on the Netgear switch as follows: VLAN 1 is production VLAN and is marked "U" on all ports except 28 which is blank. Port 27 is marked "T" on VLAN1. VLAN 99 is for guest wifi and is marked "U" on ports 1-6. It is marked as "T" on port 28. All ports have PVID of VLAN 1 except port 28 which is PVID 99.
When users connect to the guest wireless, they get assigned the proper IP address but cannot get out to the internet.
Production wireless works perfectly.
Any thoughts are much appreciated. Please let me know if more info is needed to help diagnose. THANK YOU!
