What you should do is whitelist our router IP addresses in your firewall so that they won't get blocked. Our router clusters use many different IP addresses so the best way to identify them would be by checking the hostname of the IP address. All of our router IP addresses use a similar hostname pattern which looks like this:


For example:

% host domain name pointer router-1.ash.us.router.prioritynap.net.
