Need help configuring pcanywhere through cisco 677 router

[compugeek]

Hey all,
I've been wrestling with trying to configure pcanywhere through our dsl router.
We use a cisco 677 series router. we telnet into the router for configuration.
I've used NAT to bind the inside ip with external ip address with the proper port #'s and proto's. we only have 1 external ip address. I use pcanywhere and need to connect to a machine inside our network. the way the router reassigns the ports and ips has made it impossible thus far. All the machines are running win98se BTW. Should I use VPN?
Any help would be greatly appreciated.

thanx

So you want to be able to PCAnywhere from an external IP address *into* a box that sits behind the router (on a 192.168.* address I assume)?

Have you configured NAT on the Cisco so that ports 5631 and 5632 are always forwarded to the IP address of the machine you want to control?
