Did update from RUT2XX_R_00.01.06.1 to RUT2XX_R_00.01.07.1.
I have one device listen at 5900 for local VNC connection, didnt work after update. Access from WAN via port forwarding is fine.
Also cameras with port 81,82,etc.. cant be accessed within LAN, WAN is fine.
Downgrade to version 6 and restored config, everthing is fine.....
