Adding a new firewall rule causes internet disconnection.
When I try to add new firewall rule, the internet connection in my LAN is disconnecting. Can anyone please help me to get rid of this.
Can you check if your states are getting reset? Look at Diagnostics > States, check the count before and after.
What features do you have in use in the router?
Some people have reported this issue before, but so far nobody has been able to reproduce it reliably.
Also, are you on 1.2.3 or 2.0? If you're on 1.2.3, try 2.0. If you're already on 2.0, ensure you are on the most current snapshot available (should be from the 12th)
