Issue
NPR Connectivity over the Internet
Product Line
TAC INET
Environment
- I/NET
- NetPlus Router (NPR) Series 2000
Cause
In most cases when communication occurs over the Internet, firewalls are in place to block non typical ports. I/NET utilizes Ports 50069 (set by default). These ports usually need to be configured within routers to allow I/NET to communicate correctly.
Resolution
Receiving messages from one I/NET System to another over the Internet through an NPR that is behind a Firewall. In order to accomplish this there are several steps that need to be done.
- Configure the NPR with a static IP Address.
- Set the Host Masking to send and receive messages (this will not be available when directly connected).
- Remove the NPR from behind the firewall and connect outside the firewall. Connected directly to the Internet.
- Set the Host Masking so that it can receive messages.
- Once communications have been established, You can now replace the NPR back behind the firewall.
Also refer to Which ports must be open on a commercial router in order to communicate with an NPR over a WAN? which discusses ports utilized by I/NET.
For cases where you are using the Xenta Server 527 NetPlus Router (NPR) refer to TCP/IP Ports used by the I/NET system: UDP Port Settings.
