New box with Windows Server 2008 R2. There is specific software that needs to establish a session using ports 5001&gt;5021. I have created seperate rules for TCP &amp;&nbsp;UDP traffic and it will not work. Another software that uses Telnet - will work however. I also am not able to telnet into any of those ports locally or from another box.<br />
<br />
Thanks
