[assistenzanet95]

after a configuration restore, the mac filtering on the captive portal relating to the sip protocol (UDP) of voip phones authorized for traffic to the lan does not work anymore . vers. 2.6.0 current , backup version 2.4.5. changing the method from mac to ip everything works

You have some digging to do in the past, here, on this forum.
If I recall well, when 2.6.0 came out, there was an issue with the portal : only TCP was passed, no UDP, no ICMP.
Solution were posted, and there was even a system patch that came with the pfSense system patcher packge (?).
