Random webpages stop workin...

RouterOS General

This morning we got a problem at work. We started to get 403 error on some websites.
I can’t ping those sites..

I have tried to reset the CCR and inactivate all FW rules. Nothing helps. If I change the router to another Mikrotik it works great.

Help plz.

If you get 403 then the server does reply. Ping is irrelevant (they may just blocking it - it has nothing to do with HTTP).

403 means forbidden.

Do you use webproxy? Maybe you messed up something there…
