Hi what do u recommend me to do for my wisp, i think to have a machine in my office with mikrobill installed, but i also saw that i may have a dedicated server and install mikrobill and then connect to my home mikrotik router, what do u recommend to have a dedicated server somewhere else or its better local in the office.

thank you.

you can easily run mikrobill on VPS like digitalocean.com for 5$ a month. Mikrobill has ppp plugin so you can make vpn connection to your core router and then mikrobill will be able to access all routers in your network even if they have internal ip adresses.
