Can't access TL-SG2428P switch from different subnet
I have a TPLink TL-SG2428P switch. Port 1 is trunk port for 3 VLANs and the LAN. The LAN is the default assignment for all ports on the switch and the switch's static IP for management is on the LAN at 192.168.10.2. Several ports are configured as untagged ports for the VOIP VLAN, one is tagged with 3 VLANs for the TPLink WiFi AP. Currently I can only access the web UI of the switch from devices on the same subnet as the LAN (192.168.10.0/24). It does not respond to pings from devices any subnet other than 192.168.10.0/24. How to enable access to the switch from other subnets? i.e. my LAN3 VLAN is on a different subnet and there is a firewall rule in place to allow traffic from LAN3 to the LAN where the switch is located, and devices on LAN3 have no problem accessing other IPs on the LAN, EXCEPT for the TPLink switch.
