How can I join two home networks, or have an outside computer recognized by a network and trusted?

My son and neighbors have some games that can be played multi player on networks. We both have DSL. I would like to be able to temporarily join networks, or have one computer there to be recognized and trusted on my network so the software thinks it is one network. Does this have the slightest chance of being done?How can I join two home networks, or have an outside computer recognized by a network and trusted?
Just forward the port(s) the game requires (in your router) to your computer, and give your external IP address to your neighbor (or use a dynamic DNS service to get a named address). See http://www.portforward.com/english/route鈥?/a> Pick your router, then pick the game, then follow all the instructions.How can I join two home networks, or have an outside computer recognized by a network and trusted?
it can be done you just have to create names for pc's and access to each others networks, simpler if both on same ISP but? Or create a room to log into a room of some sort. To prevent lag as such you may have to a server of some sort which is just a pc with lots of ram and a superlarge hard drive
Option 1 ) See if the game allows you to create password protected games. Host/Serve the game and put a password on it. Give the neighbor the name of your host and the password. Using the mutliplayer feature of most games...they should be able to find the game your hosting and enter the password to connect.


You might also have to give them your WAN IP which can be found by going to whatsmyip.com








Option 2) Have the neighbor connect to your network wirelessly assuming they are within range of your wireless access point. You might even build a better wireless antenna for about $3 in parts or using the stuff around your house to boost your signal/range.

Option3) If your neighbor is just next door or over the fence.. consider buying some plastic PVC pipe (used for sprinkler systems) and buy some network cable and run cable between the 2 houses. You could even split the internet bill between both houses if you wanted to.


(This is what we my parents and I did with our neighbors next door)





Option 4) Research and configure a Virtual Private Network (VPN) so the 2 separate networks can communicate..but this is way too complicated for your application
