What I have:
Unifi 48 port switch
Unifi Nano HD
Sonicwall TZ500
I have the SonicWALL TZ500 setup with two VLAN’s. One for internal Wi-Fi, one for guest Wi-Fi. One is X0:V50 which has access to the Corp LAN by default and the second one X0:V100 which is for Wi-Fi guests and should be isolated. The VLAN’s work properly between the SonicWALL and the Unifi 48 port switch (Setup as VLAN only) but Sonicwall puts the VLAN’s in the “trusted zone” which means even VLAN X0:V100 can ping/access the Corp LAN.
What can I do to segregate the X0:V100 VLAN so it's isolated?
