Using Remote access if going through NAT server

[adam26]

Hi

I have recently tried to connect to another computer through UltraVNC and it has not work.

I was told by the ISP of the computer that im trying to connect to that they are on a NAT setup with their server and dont have a public IP. He has told me the IP address of the NAT server and the IP of the computer inside of it.

Is there any way i can still use remote access in this setup? (i was advised by the ISP that i cannot unless the computer has a public IP)

If i can, What program should i use?

Thanks

Adam

They need to add a static NAT statement to their server to translate their public IP to the private RFC1918 ip address of the computer that you are trying to connect to, since private IP addresses are not routeable on the internet---the address gets translated via a port (many-to-one NAT, or PAT) attached to the IP address of the outgoing interface (public) so that it can then be routed on the internet. Coming back in, packets go to the computer on the inside because the server translates the public IP address to the inside LAN (private) ip address of the computer, because of a NAT statement---"if people try and connect to my outside interface via the UltraVNC TCP port 881, then route these packets to 192.168.11.112"---I am not sure what port VNC uses, nor do I know the ip address of the computer on the inside---but hopefully you get the gyst of it and what the static NAT statement instructs the server to do.
