I am currently trying to get the Main PC as per the diagram to talk to other devices in the network.
The setup is as per the diagram below. This is due to a terrible VOIP company and how they need it set up.
I have reset the MicroTik and have not removed the default settings after reset and the Main PC gets Internet.
I can even set up PPTP connection to other Mikrotiks outside of the network but cannot have my Main PC seen buy others on the relevant ranges.
I have disable all firewalls with no luck either
Any advice would be appreciated.
