I´ve setup RRAS with VPN, selected to use DHCP server and end result is:
RemoteAccess Event ID 20169: Unable to contact a DHCP server. The Automatic Private IP Address 169.254.90.105 will be assigned to dial-in clients. Clients may be unable to access resources on the network.
This RRAS acts as a gateway and NAT to all my interfaces, connecting every server and Client to each other via different NICs. These physical and virtual connections (NICs), works fine and IP adresses are received fine. Only the VPN interface doesn´t work. In RRAS IPv4 settings, I selected VPN nic to be the one to receive the adresses. DHCP server is able to ping that nic, and gateway is set correctly.
If I change the VPN DHCP settings to a static pool, it works, but I would like to use DHCP server
