Thanks guys. By the way, I have just noticed that while this gives an error on 1.0.2: add rule inet filter input iif lo time < "2022-07-01 11:00" accept This does not: add rule inet filter input iif lo meta time < "2022-07-01 11:00" accept The use of 'meta' in front of 'time' works around the bug. -Martin
