MItel Border Gateway port scan question

[lordheetsink]

We use a MBG for remote handsets using MiNet.

A routine port scan from a consultant showed 7 ports responding: 80 and 443, 1723, 3998, 6801 and 6881

I need an explanation of why these are open, or I need to close them.

aside from 80 and 443, I cannot find either documentation explaining why the other four are open, or where they are set. the ports page on the Mitel Standard Linux/Network Port Ranges page does not list these. am I looking in the wrong place?

this also refers to other port values: http://micc.mitel.com/kb/KnowledgebaseArticle51887.aspx

I am guessing:
1723 - Point to Point protocol - how licensing gets pushed to the appliance
3998 -  Switch Application Communications, for button programming
6801 and 6881-  real time streaming protocol for streaming audio

Lordheetsink,

These ports are for Teleworker Phones to connect to the MCD through the MBG.

3998 - SAC SSL
6801 - MiNet SSL
6881 - Set HTTP Proxy

As for 1723 that would have to be something other than a Teleworker phone and I don't see that as a port going to the MCD or MiCollab either.

Thanks,

TE

thanks for the help, the unit has Point to Point Tunneling Protocol turned on for Mitel support. PPTP uses port 1723 by default. it would be nice if that was explicit in the MBG documentation.

FYI... If you download Teleworker Network Analyzer and run it, you will see every port the MBG uses.
