I have RB450G and 3 wans configurated in PCC and 100 users after router.
When i go to vkontakte.ru site only reloaded and don’t login.
Anyone have this problem?
only this one site? sorry but in that case, most of us can’t test it, we don’t have an account there 
I’ll give you my account)) to test in PM
are you really sure this is the only site not working? maybe the problem is not related to RouterOS then? what is so special about this site>?
only this site reloaded, other social sites work fine.
what are your wans? what PCC classifier do you use?
use both-address
check with ‘src-address’
