Besides dummy stuff like wrong config of knockd itself - which hopefully gets ironed out during initial (local/on-prem setup). Every now and then particular knock ports might be blocked (DROP) by cliënt side ISP/wifi/etc you happen to be using at the moment. Or your fiber optic connection package gets a speed boost, along with being moved behind CGNAT. OK in my case switching from cable to fiber already included ending up behind a CGNAT, but people already on that ISP actually got that 2in1 surprise. |
