DSL is no problem for that matter any broadband connection should not be an issue.

If you have done that and getting errors , let me know

A routable IP address for the Host. Refer to the document How to determine the IP address of a pcAnywhere host for additional information
Port forwarding to forward ports 5631 (TCP) and 5632 (UDP)

Nice links there. I agree, have the routers default to filtering packets, then add such as these when needed.

Very important, I think, is to ensure that you have set up strong authentication between the two (ex: password) prior to connecting to network.

Just a little security information here,  even through you are behind a router, and you are now on a private IP address, you are no secure when you open up something like PCAnywhere on a computer, and foreward the ports to the router.  And cracker with a scanner can find the open port into your private network, and if he can gain access to PCAnywhere, he has complete access to your internal network.

A better, much more secure solution, would be to put a VPN server into the network that you are wanting to get into, and just VPN into the private network, and then you wouldn't have to foreward ports.  You would just connect from your public computer, to your private computer.  Check into a VPN solution before you go the route of port forewarding.  If you have DSL, and you only have 1 IP address, and its sitting on your router, look into Wolverine.  Its a very good, very secure router/VPN/DHCP solution that is very easy to setup, as long as you know what your doing. http://www.coyotelinux.com/

jetnet is right. You are not going to want to open your network up to random hacks at your PCAnywhere connection. A decent VPN solution will ultimately be your best solution. You can find many inexpensive DSL VPN router devices from Linksys, D-Link, and others. Or, if the budget will allow, you can go with a more high-end vendor solution. Either way, don't do it this way-- go with a VPN.

Hey zolpo,

A much safer, easier and more flexable solution is GoToMyPC 4.0   Download a trial and check it out...

http://www.gotomypc.com

Install it on the "server" and you can access it from any other computer in the world with a web browser.  Just go to their site, log in and you're connected using a 128-bit VPN with NO holes open in your firewall!  Very cool.  Very easy.  Even works with Dynamic IP's now.

Tip, if you go the PCAnywhere route change those default ports on both machines! (you don't have to use 5631-TCP and 5632-UDP)  There are many "automated tools" looking for those ports ;-)

One tip to secure the pcanywhere connection is to use ms proxy or ISA server which you may already be using.  Open up the 5631 and 5632 but only allow the REMOTE HOST to be your remote hosts IP address (assuming you have static external IPs).  I can explain this in more detail if required.
