I have a issue connecting Sophos AP to specific VLANS (Bridge to AP VLAN).
The issue is that I am not able to get any IP from the DHCP when connecting to the configured access points. The AP is connected to a switch, but I have even tried to connect the AP directly to the Sophos Firewall without any luck.
Any ideas what I am doing wrong? Does the switch port the AP is connected to need to be in trunkmode? Tagged? "Both/Hybrid"? I feel have tried everything.
Thank you for contacting the Sophos Community.
Make sure you’re allowing the correct VLAN on your switch and that VLAN Tagging is turned on, and make sure you’re not using VLAN ID 0 or 1 for the AP VLAN ID.
Try running a tcpdump on the XG on the VLAN interface, and see if you’re seeing the DHCP requests coming to the XG
# tcpdump -eni Port1.99 port 68 or 69
I read somewhere that I should avoid VLAN ID 0 and 1, so I have basically worked with VID 3, but I'm not sure I have tested it with tagging. I'll test that and do a tcpdump :-)
