Примерно чуть более месяца назад приобрёл роутер MikroTik hap hac2, настроил по Quick set, после настроил ещё только dns сервера и пару статичных адресов в DHCP. Всё это время он работал без нареканий.
Но пару дней назад почему-то стал выдавать no route to host на публичные адреса, хотя при этом пинг до хоста работает и telnet по порту из роутера выполняется успешно (no route to host - с клиентов). То есть, с клиентов:
$ ping github.com
PING github.com (140.82.118.3) 56(84) bytes of data.
64 bytes from lb-140-82-118-3-ams.github.com (140.82.118.3): icmp_seq=1 ttl=56 time=51.8 ms
$ telnet github.com 22
Trying 140.82.118.3...
Trying 140.82.118.4...
telnet: Unable to connect to remote host: No route to host
С терминала роутера же всё ок. В чем может быть проблема?
Да, после перезагрузки на некоторое время проблема исчезает примерно на несколько часов.
Привожу конфиг:
