IP addressing of DSL

Scenerio: I have a DSL line installed and also a LinkSYS router. All is working fine internally with 10 workstations on a 192.x.x.x network. The problem I have is that the IP is being recieved dynamically and the IP that shows as my WAN connection is not one that I can ping from another computer outside the LAN. When I ping the DSL dynamic address it comes back with host unreachable. I need to get to that IP to run pcAnywhere on 1 workstation on that LAN. I have the ports forwarded and all thatbut the IP address cannot be pinged…and therefore pcANywhere will not work. HELP!

Thanks
