In my setup have two routers, server and client with openvpn tunnelling. After I configurate Openvpn client LAN port (for example 192.168.1.2 when DHCP is disabled), should is DHCP switched to enabled again on client router? And also should is LAN protocol be DHCP?
Actually, I have to change LAN port IP address to 172.21.1.3 and 172.21.1.4. Is it possible in the required range for DHCP?
