Lan Constant Connection Network Adapter Specifications - Pitney Bowes K700 Networking Manual

Constant Connection LAN Adapter Specifications
1) LAN Adapter Network Requirements

The System requires an Internet connection, accessed through a Wired
LAN.

The System supports 10/100 Ethernet transfer rates; Full Duplex.

The System will initiate all communication.

The System will initiate all communication via HTTP and Active Mode FTP.

The System will communicate to external Web Services via HTTP using port
80.

The System will communicate to PB data server via Active Mode FTP using
outbound port 21.

The System will use Port 53 for DNS lookup.
2) FTP Type Required

The system will use FTP "Active" mode for all FTP communication.

On server port 20 for data and port 21 for commands must be opened.

On the client, ports > 1023 must be opened for successful FTP
connection and transfer of files.
3) Firewall Access Requirements
It is recommended your meter be connected through a firewall. If
unrestricted outbound access is not allowed in a particular organization,
then Network access to Pitney Bowes' servers is accomplished by allowing
access to the domains listed in the Network Firewall Access Specifications
(Page 6). To avoid potential future firewall issues, it is highly
recommended domains are used instead of IP addresses, because IP
addresses have a tendency to change.
4) Communication type when meter connects to the PB Data Center

The system uses (HTTP) on Port 80 and FTP on Port 21 for
communications to Pitney Bowes Data Center Servers.

Port 80 is used to communicate XML formatted messages requesting
services.

5) HTTP Communication Type
The System only supports "chunked" HTTP Transfer Encoding
communication when connecting to Postage by Phone. Your network must
allow this type of communication. The firewall/proxy and all components
along the communication path need to allow empty client side chunking
messages through on port 80. Our systems use HTTP 1.1 Chunked Transfer
Encoding when we communicate with Postage by Phone. HTTP 1.1
Chunked Transfer Encoding allows HTTP messages to be broken up into
several parts. Some network protection devices see this as an attack and
block it. Chunked Transfer Encoding is a method in which only a portion
(or chunk) of data is sent by the server in an HTTP/1.1 session. It is often
used when a server knows that it will take a long time to complete a
client's request, and so it sends only small chunks of data as data is
dynamically created.
Some newer versions of Meter Software will encrypt the "chunked"
communication to avoid any perceived security threat that a firewall or
security cloud may detect.
6) Static & Dynamic Addressing
Your System supports both dynamic and static addressing. The IP address
is defaulted to automatic addressing from a DHCP Server. You can view
and/or change the LAN IP settings using the meter menus described on
Page 11.
