Hello,
Yes, on RUT240 firmware RUT2XX_R_00.01.12 fields “Virtual local endpoint” and “Virtual remote endpoint” are mandatory and cannot be empty. You should add correct IP addresses:
Virtual local endpoint - client’s local address in the virtual network.
Virtual remote endpoint - client’s remote address in the virtual network.
IP addresses have to be host from network /30, for example 10.10.10.5 + 10.10.10.6; 10.10.10.9 + 10.10.10.10; …
