I have a Fritz!box 7590 with a static ip on the internet side.
I configured a series of portforwording to the RED of the firewall.
Everything worked without problems for about 1 year, for about 10 days, the port authorizations set on the router have been automatically deactivated.
Firewall and router updated to the latest version.
I also tried replacing the router with an equal model, restoring the backup, but nothing came back.
To re-enable everything I have to enter an authorization, change the port number, apply and then re-edit the port.
This is what the 7590 system log reports:
01.09.2323:51:33 Removed enabling for port 444 on XXX.XXX.XXX.XXX (Firewall).
01.09.2323:51:33 Removed enabling for port 8000 on XXX.XXX.XXX.XXX (Firewall).
01.09.2323:51:33 Removed enabling for port 222 on XXX.XXX.XXX.XXX (Firewall).
01.09.2323:51:33 Removed enabling for port 8123 on XXX.XXX.XXX.XXX (Firewall).
01.09.2323:51:33 Removed enabling for port 180 on XXX.XXX.XXX.XXX (Firewall).
01.09.2323:51:33 Removed enabling for port 443 on XXX.XXX.XXX.XXX (Firewall).
01.09.2323:51:33 Removed enable on port range 1194-1200 for XXX.XXX.XXX.XXX (Firewall).
01.09.2323:51:33 Removed enable on port range 80-87 for XXX.XXX.XXX.XXX (Firewall)
Has this ever happened to you?
Could it be the rpovider disabling this?
I have TIM, I live in Italy, and the router is theirs.
