Only one machine can not access web gui of the router.
In firewall for that machine the last log is:
state: FIN_WAIT_2:FIN_WAIT_2 Arule: anti-lock rule
Machine have ping to router.
When try to access port 80 to open web gui of opensense router it is just loading in browser client machine and not returning any response from router. Stay that, just loading. From other machine not have the problem and I can access web gui. This is how I see logs.
