I have a broadband internet line which connects to a Netgear DG834GT modem router. Needless to say, my public IP address is dynamically assigned by my ISP (Wanadoo). My router then issues private IP addresses via NAT and DHCP. My routers internal IP address is currently set to 192.168.0.1. I want to set up my PC - which dual boots between Windows Server 2003 and Windows XP Pro - so that I can dial into it from a friends house using VPN. I should be able to use RRAS in Windows 2k3 Server and configure a VPN connection in XP Pro. But how would I do this? When running in 2K3 server mode my PC uses a static IP address of 192.168.0.2. When running in XP Pro mode it picks up an IP address from the router. I am running DDNS on the router and have registered a domain name to be associated with whatever IP address I get from my ISP. I also have a broadband modem and wondered whether I need to use that instead of the router since then my public IP address will effectively become the IP address of the PC (thus permitting direct dial-in) rather than the router.
