refresh FQDN problem

Hi,

 

We have several computers in our network using this proxy: proxy1.eu.webscanningservice.com

This domain changes IP each 15-20minutes. So when this domain changes the Ip we can reach the proxy from our computers.

So i have several doubts:

1)PA detects when a domain changes the IP and update the FQDN database?? or only FQDN refresh is done each 30minutes???

 2) What would it be the best way to create a rule with a FQDN host which changes IP each little time????

 

Thanks a lot

Re: refresh FQDN problem

The default FQDN refresh time is 30 minutes and can be reduced down to 10. If your IP updates every 15-20 minutes you might want to script a that calls on the api to force a request system fqdn refresh even faster than every 10 minutes if needed. 

With a host that changes IPs that often, especially somthing like a proxy, I'm not really sure even using it is the best option. There are multiple potential issues that I can think of off hand, none the least is that regardless of how often you refresh the FQDN database you will have a time where the IP address doesn't match up and you won't have the correct IP address for your proxy.
