Is there any way to communicate with a computer with a different IP range?

Question

I need to communicate with another PC that have different IP address ranges to my own.

I cannot change either and I have no control over network routing.

Is there a piece of software that I can use to bridge between the two Ip ranges and allow me to achieve this?

Answer 1

Well, the whole idea of IP is to allow different networks to communicate, so the very basic answer is yes, but of course, the devil is in the details.

If there is no NAT being done between the networks and all routers between them have the correct routing tables to get from A to B and back again, then you should be able to just use the IP address of the remote machine directly. (Assuming that your desired communication uses IP and not some other protocol, such as IPX or Netbeui)

If you're talking about Windows filesharing, then you can simply put in the IP address in the start -> run prompt
\\192.168.75.47\c$ for instance. The other machine will need to have permissions set properly of course. If you want to see these by name, you'll need to either set up and use a WINS server that both machines talk to, or have an active directory server that puts both host names in DNS.

You could also try setting up VPN between the networks.
