First of all, my native language isn’t english; so, i’m very sorry if i made a mistake in grammar.
I’m very newbie in Mikrotik; in my configuration i use OpenDns (i don’t know if it’s relevant for the problem), but sometime ago (since 1 or 2 months) i can’t access to any website with http; just only https sites.
Example, if i’m trying to access to www.google.com, any computer in my LAN can’t access; but if i write https://www.google.com in the browser then i have no problem to open the site.
No matter the site, all HTTP is blocked.
I don’t remember to put any firewall rule that could do this, can somebody help me?
Thank’s!!
most probably you are blocking port 80 with some firewall rule, https uses port 443 so you don’t have the same problem as with http
have a look at the forward chain for a block/drop port 80 rule
It can also happen if you create incorrect dstnat rule for port forwarding, which works for incoming connections, but breaks outgoing.
