Network configuration advice with leased line
I have this configuration that seems kind of odd to me.
Site A and B are connected using a radio link (like a leased line)
The lan devices from site B use the internet connection of site A as the main internet connection, the backup one is to be used only if the radio link fails.
Right now it is working except some issues like an ip scan from the 2 lans not working.
I think there is a better way to configure this network. I was thinking of setting the radio link interfaces both as external, and set up a BOVPN between the two interfaces, if it goes down, the backup line for site B is used.
Is this a good solution to configure the network or is there a better way in your opinion ?
