is it possible to remote control into another PC which is using NAT IP? the PC is connected into the internet via a ADSL router.

I do it with PCAnywhere. You have to forward the relevant port numbers from the router to the PC you want to control

Yep, VNC does it fine. Use it on loads of different machines

As above - you need to know the specific TCP or UDP ports the remotecontrol software uses then set these up on your router/firewall to a) be let them through and b) be forwarded to the right IP of your PC. If possible you should allow the connections only from known IP addresses - but your router might not support that or if you're dialling into the Internet you might not know the range your ISP uses.

basically what i want to do is to remote control another PC that is connected to the internet via an adsl router. my connection is also via adsl but using win98se ICS on a hub.

my_PC-hub-ICS-USB ADSL <--internet--> ADSL Router-PC

so both PCs are using NAT IP. how would i control the PC if the IP is not "real"?

As above.

First you need to install R/C software on both PCs. Then, armed with the port number(s) used by this software, configure the router at the slave end to forward those ports to the PC you wish to control. Run R/C software on slave to listen for connection.
You also need to know the (dynamically allocated) IP address allocated to the (slave) router by your ISP.

On master PC, run remote control software, connect it to the IP allocated to the slave router, which will automatically forward the incoming packets to the slave.

Example. The ISP gives the slave end router the IP address 123.456.789.100. The r/c software uses ports 5000 and 5001, and the PC you want to control have the NAT address 192.168.0.1

Configure slave router (123.456.780.100) to forward posts 5000 and 5001 to the PC 192.168.0.1. Start R/c software listening (host) mode.

Run master PC in remote mode. Set it to look for the host. 123.456.789.100. The request will pass thru the router and to the PC (192.168.0.1), giving you a login screen. Authenticate and you're in.

Depending on router/remote software, you might be able to set it up so that it only allows a connection from certain IP addresses. This offers increased security.

You could also subscribe to a DDNS service (www.dyndns.org). You get a virtual web address to allocate to the routers, so that you connect to this, rather than the IP. When the ISP changes the IP address, the DDNS record is updated, so you always connect to the same virtual address irrelevant of the actual IP address.
