I hava been configured all what is needed, it is just routing. When i try to ping from Mikrotik Terminal to out of internet, i got “Net Prohibited” message. I know the problem, that is happen because the source of eth1/internet is from mikrotik too and the admin gave the hotspot login. So, if i try to connect my pc i need to login, but when i try to use the cable that there is have a hotspot login as internet/eth1 source, i got “Net Prohibited” . So, why i can login from Mikrotik Terminal to have access internet from a cable that there is have Hotspot login ?
