Hello. This router worked well last week but the firewall does some strange things. After setting the rules, it works, but after a while it seems like one of the rules is disabled (the behaviouris like it is). Besided that, if I try now to update the rules (trying to recover the right behaviour), the loader icon stays forever and the only way is to refresh the web page of the router. After that, the router continues working (not as expected, but working).
