VPN

[Guest]

I can establish a Remote Desktop connection when my laptop is on my home router (which is where my host desktop is).
I cannot establish a remote desktop connection when my laptop dials up to the internet. ( get an error that says it doesn't recognize the IP address of my host computer.)

Strangely, it can ping the host, and it can establish a netmeeting with the host, so I know the IP is accessible.
I've forwarded port 3389 to my host computer, which is has a static dhcp address.
Do I need to establish a VPN first to communicate with my home network?! It seems that I should just be able to type in the IP address.

Any ideas?

You need to call the public WAN IP address, ie. the IP address assigned by your ISP, of the router.
When this fails is the laptop connected to the LAN and dialing out the modem at the same time?

1st - Make sure it is the public IP address you are using when dialed
in.

2nd - Make sure that you configure TCP Port 3389 just like you did for
the appropriate Netmeeting ports.

You shouldn't need a VPN connection - unless your ISP is blocking TCP
Port 3389 - some actually do this. If you are experience port
blocking, the only alternative is a VPN.

I think I'm using the public WAN IP address. I'm using
the address that is returned by whatismyip.com, which is
also the same IP address that is displayed on the "status"
screen of my Linksys router.

The laptop is not connected to the LAN while it is dialing
out the modem.

More experimentation revealed that when I give my IP
address to friends at home, they can connect to me using
netmeeting, but not Remote desktop. I'm pretty sure port
3389 is forwarded correctly because it works while I'm on
my LAN.

Any other ideas?
