Ive added a new interface in Genesis called mac0 with its IP set to 192.168.1.15 and its gateway to 192.168.1.254. (to me this didnt sound very logical but the manual says so)
I've no experience with vlink, however, have you tried using the gateway of the other device (192.168.137.1) instead of 192.168.1.254? Make sure the netmask on both devices is 255.255.0.0.
