What IPs does Shoutcast use to communicate with AuthHash servers?

We are currently having issues getting our server to connect to the AuthHash servers, and we think it's part of our firewall. What port do we need to open/IP to whitelist in order to allow our server to communicate with Shoutcast YP?

what errors are you specifically getting and have you installed the v2.2 update (as suggested in your other thread) as that reolves a number of YP / authhash connection issues. as knowing the errors would be a better starting point.
