Есть два микротика - RB951 и hAP lite. Новые, пришли на замену двум совсем старым 751, по причине смерти одного из них.

Один стоит на складе, другой в офисе, провайдеры абсолютно разные, но проблема одна и та же: не открывается в vk.com и 2ip.com. Возможно, еще какие-то, не знаю пока. Причем пинги идут, но вместо странички в браузере ERR_CONNECTION_TIMED_OUT. 

Обе железки практически в дефолтном конфиге, изменены только настройки Wi-Fi и добавлены учетные данные от PPPoE.

 

Нашел два решения в интернете: как-то изменять MTU(так и не понял, как, вернул дефолтное 1500) или добавить правило в mangle, изменяющее MSS.
 

Ни то, ни то не помогло.

 

Подскажите, пожалуйста, кто-нибудь...

 

Экспорт конфига под спойлером.
