How to open ports for pcanywhere on 678 router

My client is using Cisco router 678. When I enabled ports 5632 and 5631 for pcanywhere by using set nat entry add 10.0.0.50 5631 223.224.83.2 5631 tcp and set nat entry add 10.0.0.50 5632 223.224.83.2 5632 udp, it worked fine.

Now, they want me to add two more pcanywhere accessing through the router. I thought I might be able to do this by opening different ports and command like this: set nat entry add 10.0.0.49 5631 223.224.83.2 20000 tcp and set nat entry add 10.0.0.49 5632 223.224.83.2 20001 udp. But that didn’t work.

Even worst, the first pcanywhere (10.0.0.50) doesn’t work any more even thought I delete the second pcanywhere settings (set nat entry delete 10.0.0.49 5631 223.224.83.2 20000 tcp and set nat entry delete 10.0.0.49 5632 223.224.83.2 20001 udp). Please refer to below show nat.

1. How can I make the first pcanywhere work? Or what’s wrong with the settings?

2. How can I setup more than one pcanywhere to access the same IP?

cbos#sh nat

Re: How to open ports for pcanywhere on 678 router

1) With a NAT gateway running on this single computer (the Cisco 678 router in your case), it is possible to share that single address between multiple local computers and connect them all at the same time. But, not more than 2 pcanywhere can be supported in a 678 series router. This might be the reason for the issue.

2)To make the first pcanywhere work, try removing the existing nat entires and then add them again.
