Windows 7: External IP

External IP

Hi,
I have a cisco Valet M10 router and I want to use the built in VPN on my two Windows 7 laptops. I was wondering what ports I need to forward to my laptop. My router has 1 external ip address and assigns it to all the computers. Please help!

Your router does not and can not assign the same IP to every computer. If it did the network would not work at all. And the router gets 1 public/internet IP address and that is on the WAN port of the router. It hands out private IPs to all components (PCs, printers, whatever) connected to the network.

So you want to VPN into your home network from a remote location. Right?

UUMM, when you setup a VPN you are essentially making yourself part of the local network that router controls and are given an IP as if you connected to one of it's LAN ports. You usually need to find the settings to allow PPTP, IPSec and VPN passthrou. once this happens [on router] you will usually need to set a client computer [that has actual VPN server software unless the router handles this then make sure you set it up to make you part of the LAN you already have setup [if you get a different Subnet and the VPN connection is not bridged to the LAN you will connect to VPN but not be able to see any of the rest of the network]/ Once you hav VPN and the passthrough all set you will prolly want to head over to DynDNS and grab an account so you can put this info in to the router to update your DHCP IP from your ISP to some.example.com so you dont always have to know the IP. Once it is all set you will need to download [or use from the client software on the CD that came with the router [or check their websites support section as it should be there as each company has their own clients that work best with ther VPN server [there are generic VPN clients just try to be sure they list your router IE Cisco dont worry bout the exact model]. Once you input your DNS or IP [usually the routers WAN IP if IP] and click connect it should not prompt you for a user and password. Keep in mind this is not as nice as remote desktop in that you will now be a network client and would need to connect to any network shares or start your remote desktop sessions [usually involves port forwarding in the VPN client depending on setup]. It is not like RDP where you connect and get a remote desktop and viola from there you are now a client on that network [and the one the client is already connected to as well] which is why tunneling comes in to play. If you just want connection security I highly suggest you check out something like WinSSHd that allows you to connect to a computer using an encrypted TCP tunnel, then you can port forward [inside PuTTY to allow you to do a remote desktop or issue commands in the command shell to be run on the network you are connected to]. For instance anytime I setup TighVNC [or well any VNC] I use WinSSHD so the session is encrypted. To do this I open PuTTY tell it the address, that it is SSH, my user/pass and the fact I want to tunnel port 5900 [VNC default] to my SSH client. Then I connect put in my user/pass, and once connected start the VNC client and connect it as if I was on the LAN I am connected to [a little extra work to be sure but 256-bit AES encryption is WAY better than NONE!
