Evening everyone,

I seem to be having issues with our 2820Vn. Ever since upgrading the firmware to 3.3.7.3, none of the open port rules seem to work.

Troubleshooting steps taken:

1) Rules re-created
2) MAC > IP Binds checked
2) Router configuration reset

Example rule:

Comment: SSL VPN Server
WAN Interface: WAN1
Local Computer: 10.1.100.xxx

1. Protocol = TCP | Start Port = 443 | End Port = 443
2. Protocol = UDP | Start Port = 1194 | End Port = 1194


Downgrading the firmware to 3.3.5.2 instantly solves the problem.

Has anyone else come across this and/or found a workaround?
