443? Isn't that the port to connect to your external proxy server so you can bypass any internal filtering? :)
Unless of course the internal filtering has good https inspection. Not many do though. -----Original Message----- From: Kurt Buff [mailto:[email protected]] Sent: Wednesday, 29 September 2010 4:03 AM To: NT System Admin Issues Subject: Re: Outbound firewall ports Ports 21, 80 and 443, and only for the proxy server. I have ssh open outbound to specific customer sites that we support . I was forced to open 544 (rtsp) recently for a live video event, but did that for a single IP address so that the machine showing the event in the lunchroom could get to it. I allow DNS outbound only for our DNS servers, and NTP for our NTP servers. That covers most of it.
