I have two sets of networks . I want to make a HLDS via internet . See the Image below. I have intra LAN connection for both the networks but there is no inter LAN connection. I have NO STATIC IP. Is There any free software to port forward my ports. All the computers are with Windows XP. All firewalls are off. I want to do without Hamachi or any other similar software. My modem is Motorola SB5101.
