Is it possible to send a packet from an external source to a specific internal IP... aka say I wanted to connect to 55.111.222.55 and then connect to 192.168.1.2 on the internal network, or rather than connect just send a single UDP packet to 192.168.1.2, how would I do this without port forwarding? I was considering ARP as an option but java has no built in ARP support. Any ideas?

Thanks!
