Some of My clients are running software that requires the provider to have remote support capabilities via PC Anywhere. I'm using a 1720 router with NAT for my Internet gateway, and would like to give them safe passage through to my clients running PC Anywhere. I've toyed with the "ip nat outside source" command and some associated access lists, but have had no luck. My current running config is as follows:
version 12.1
service timestamps debug uptime
service timestamps log uptime
no service password-encryption
!
hostname *****
!
boot system flash 1:aaa1376.bin
no logging console
enable password *****

end
Any guidance would be greatly appreciated.

From your config it appears that you are using PAT. From the subnet mask it becomes clear that you have only one Internet IP adress available.
This means that you can enable PC Anywhere access on one PC using the standard port number for PC anywhere.
To set this up you need a static translation from the PC on the PC-Anywhere-port (I do not know which one) and map this statically to your outside adress. The global command to do this is:
ip nat inside source static tcp
To enable multiple PC's you need either more IP's or different port numbers.
Goodluck,

Leo,
Thank you for your response. Your proposed solution raises a few questions.
With regard to NAT vs. PAT, I understand their differences by acronym, however I'm having trouble differentiating their application, and whether you can have one without the other.
Secondly, I use PC Anywhere to control remote clients in office #2 through my VPN Tunnel (interface tunnel0). With my workstation in office #1 set as the remote, I simply enter the broadcast address of my office #2 network, and it scans that network returning a list of PC Anywhere hosts. At that point, I merely select the host I wish to administer. Is there a way that I can provide this functionality to my software vendor? If not, I can always set up one host up as a gateway to the other PC Anywhere hosts on my network.
Lastly, I do have a block of IP addresses, but I outsource both my web hosting and email and as such have no need to utilize them. Perhaps I now have a use for them. PC Anywhere is configured by default to use a data port and status port of 5631 and 5632 respectively, however these ports can be reconfigured.
Forgive me if I seem to be babbling, but this has been troubling me for quite some time, and I would dearly like to get my arms around a solution understand it as well.
Best regards,

NAT and PAT are basically the same - NAT means many to many for ip mappings, whereas PAT means many to just one ip. In common conversation, almost everyone refers to both nat and pat as nat. In fact, I'd say that 99.99% of people with home networks behind a cable modem/dsl router would call what they are doing nat, while cisco prefers to refer to that special case with one 1 as pat.
You could forward the ports as mentioned. You could restrict access to them via an access list, or perhaps instead, you could look at setting up a vpn for access for PC Anywhere.
Make sure you are running the latest PC Anywhere version, and check for patches, as it, like everything ,has had security issues
