Knowledge Base Article: Port Information (KB2377)
The following is a summary of KB article 2377:
With the release of software version 1.1.X.XXX, NAT functionality was implemented into
the Mitel
®
5000.
We advise a one to one static NAT (all traffic to/from the public to the private address is
forwarded unchanged). If you wish to open only specific ports to the private IP address
then these are the necessary ports:
o 5566 TCP
o 5567 UDP
o 6004 - 6247 UDP
In the 2.0.x.xxx software release the number of total IP endpoints was increased, the UDP
port range used by the system also has increased as below. The functionality and
programming of the system as far as NAT is concerned has not changed though.
o 5566 TCP
o 5567 UDP
o 6004 - 6604 UDP for 5200 systems
o 6004 - 7039 UDP for 5400 and 5600 systems
o Processor Module (PM-1) base port – 6004
o Processor Expansion Card (PEC-1) base port – 6604
5600 systems should be treated as 5400 systems as far as NAT is concerned. You will
need IP addresses for both the PM-1 and PEC-1. See KB 3352 for further details on
connecting IP devices to 5600 systems.
Comparison of Mitel Advanced Communications Platforms
Three notable differences exist between the Mitel 5000 and the Inter-Tel Axxess advanced
communications platforms:
• The Mitel 5000 platform—whether configured as a CS-5200, CS-5400, or CS-5600
system—has a single physical Ethernet port shared for all IP telephony and administrative
functions. The Inter-Tel Axxess platform has one port for administrative functionality and
SIP and potentially multiple (IPRC) ports for other IP telephony protocols. Also, the Mitel
CS-5400 has two IP addresses. The second IP address is used for VoIP only.
• Because the Mitel 5000 has a single physical Ethernet interface, it has a single network
location. It cannot operate both inside the firewall and outside the firewall.
• The Mitel 5000 platform is built on an open-source Linux
®
platform that could present a
greater security risk than the Inter-Tel Axxess platform, which operates on Inter-Tel
proprietary technology.
