Open VPN /30 Automated Pool
There is a lot of documentation for ovpn and /24, but i use /30 and my intersite routing is already designed using /30. Then to deploy ovpn and Radius server (Active directory based in my case) i need create ip pool with /30 and let routers across the corp manage a /24 splitted into /30.
I had this error randomly in my windows clients (android was working fine).
There is a clash between the --ifconfig local address and the internal DHCP server address -- both are set to 10.59.58.38 -- please use the --ip-win32 dynamic option to choose a different free address from the --ifconfig subnet for the internal DHCP server
The only solution was use a /31 in the ip pools and let the router handle the addressing.
I ended with something like this:
/ip pool
add ran=192.168.1.4/31 name=vpn-user2
add ran=192.168.1.0/31 name=vpn-user1 next=vpn-user2
/ppp
add name=vpn-user local-add=vpn-user1 remote-add=vpn-user
