My setup:

route 0.0.0.0/0 => 192.168.101.120 (DSL router)
ether1 192.168.101.128/16
ether2 192.168.191.1/16 - IP range of towers
ether2 192.168.193.1/24 - IP range of PPPoE, PPPoE server on this interface, userman RADIUS
masquerade src add 192.168.193.0/24 (I have tried 0.0.0.0/0 and not specifying)

The network extends between two of our offices.

I'd like to have the two office networks communicate.
I'd also like to be able to connect to towers and clients from both offices.

Mikrotik stands with DSL at office A, PC in 192.168.101.0 cannot see towers or PPPoE clients.
PC in office B can see towers (I opened the subnets), but not 192.168.101.0 or PPPoE clients.

What am I missing? Please help.

I do not understand this mess:

ether1 192.168.101.128/16 (network 192.168.0.0 - 192.168.255.255) overlap with ether2
ether2 192.168.191.1/16 (network 192.168.0.0 - 192.168.255.255) overlap with ether1 and 2nd address of ether2
ether2 192.168.193.1/24 (network 192.168.193.0 - 192.168.193.255) overlap with ether1 and 1st address of ether2

You're correct, it's me being stupid I had them all /24 but changed to /16 to try get it working...
