Invalid TCP State

Hi All,

I have configured VLAN in Sophos xg210 (firmware 18). the thing is I create a LAN to LAN policy to communicate between VLANs. All the VLANs are communicating fine except for one VLAN. I checked the logs and its shoes Invalid TCP state and firewall blocked the traffic

Just to be sure, you have actually no communication between this VLAN and the working VLAN? Or do you only see those errors in the log?

there are 4 VLANs in the FW, 12, 23, 20, and 24. I can Ping between all the VLANs, but I have a machine in VLAN 23 IP address is 10.10.23.50 and My WLC is in the Vlan 12 Ip address 10.10.12.2. from 10.10.23.50 I can ping WLC IP but cannot access the GUI Through browser.

In the Log viewer, I filtered the using srcip 10.10.23.50 I saw that access Denied message when trying to access WLC
