F-Secure SENSE Router port forwarding issue in firmware version 22.214.171.124
After the firmware update in version 126.96.36.199, port forwarding rules are not working.
This issue is due to the recent enablement of the multicasting functionality in firmware version 188.8.131.52, which causes user-defined port forwarding rules to be overwritten by a new IP table rule.
- Set up port forwarding rules again.
- Please refer to this How to set port forwarding on F-Secure SENSE Router on how to set port forwarding.
