Hello, I have a question that I was hoping someone might be able to help me with. I have my CCNA, but am still relatively a n00b when it comes to more advanced features of Cisco routers.
I am trying to make a change to an already configured CISCO PIX 515E router.
Basically my problem is that there is a remote router that has a dynamic ip address, so I signed them up for dyndns.org service that gave them a hostname (example: xxxx.dyndns.org) that resolves to the current IP address. I want to change the tunnel policy and also add a preshared key that uses this host name instead of the dynamic ip address, so that everytime the ip address changes I won't have to delete the preshared key and add another one for the new address. I have searched online to try to find others who have encountered this situation and what they did, but I have been unable so far to find out how this can be accomplished.
The help file for the java CISCO pdm says the following regarding pre-shared keys:
Peer Name/IP Enter the IP address or DNS host name of the remote peer for which you want to configure a pre-shared key.
This gives me the impression that you can use xxxx.dyndns.org instead of the current ip address but when I enter that (on the screen PreShared Keys->Add PreShare Key) it gives me the following error message:
"The IP Address is not in the correct format."
Am I misunderstanding the help file as to what is possible? What exactly does it mean when it says "Peer Name"? Does anyone have any suggestions?
I'm sure my question is not unique; I apologize for any duplication with regard to this question. If anyone has a link to some information that would be helpful I would greatly appreciate it.
Thanks! NCook
