Client has Netopia R7100 router acting as firewall to a small LAN - Win 98. Phoenix is the ISP, Northgate the DSL provider (xdsl 400k). No additional firewall software.

The first goal is to be able to remotely operate client workstations from my office over TCP/IP (i.e over the internet vs. dialup). We both have DSL connections through the same ISP ( mine xdsl 784k). I am going out through my Linksys DSL Router/switch which dynamically assigned IP addresses to my small network.

The router exposes one ip address to the web. Internally, of course, the workstations have another TCP/IP address.

1. How do I tell PCAnywhere the address of the host workstation?
2. Does the host workstation have to have a fixed IP address or can it be assigned dynamically (the router will do this or will do fixed IP addresses within a range)
3. Does each workstation I want to access have to have an ip address assigned by the isp?
4. I think this all has something to do with NAT and there are ports at issue, but I'm really clueless on this stuff.
5. The next challenge is going to be desktop to desktop video conferencing and automated file transfers desktop to desktop.
6. I will also want to operate/access my office from the client or tunneling over the web from the road.
7. I am a novice with PC Anywhere in other than dial up configurations

Clues appreciated. I know there are a lot of folks here who have mastered this stuff.

TIA
