Hi I have a DrayTek 2865LAC and when I upgrade to verision v2865_445_BT of the firmware I lose access to edit my filter rules. The pages dont even appear as a list, when I change to different sets I just get a blank page. If I downgrade the firmware to v2865_446_BT all the rules are displayed correctly. I have tried two different browsers and my mobile but the result is the same. Any ideas how to fix or is this a known bug?

Hi ukeyes ,

when I upgrade to verision v2865_445_BT of the firmware I lose access to edit my filter rules. The pages dont even appear as a list,

Did you mean 4.5?

I would look at the rule's comment field, most likely they've removed certain characters from use in that particular field in the recent update; it's happened before. Obviously not great that it affects the minority that have used these now-illegal characters previously. Sometimes they even shorten the field's character count which either truncates or worse moves the overflowing characters down to the next field.

Backup your full router config, then maybe try removing special characters or even spaces then upgrade again. You could try backing up your firewall rules separately ('General Setup' page) then deleting all the rules and backup the whole router again without them added, then upgrade and restore that config and then restore the backed up Firewall config, It may fix the problem for you or at least restore most of it and allow you to check through what could be wrong.

...or just wait for them to release another update where they've resolved this particular issue...

 

Sorry yes it is v2865_450_BT firmware.

Hi. I have tried the suggestion and removed all spaces and special characters but the results remain the same.
