Modify TCP Ports for HA‑DR Communications

You might need to modify the TCP port numbers used for communications between the local and remote onQ Appliances if inter-Appliance communications traverse a firewall that does network address translation (NAT) on the onQ Manager IP addresses.

•	Port 22 (ssh) — the default port for securely transmitting data. It’s highly unlikely that you’d ever need to change this port.

•	Port 81 — the default port that each onQ Appliance uses to verify that the other is “alive”; no data is transmitted via this port.

To modify the TCP port numbers:

1.	Stop protection.

2.	Go to APPLIANCE CONFIG tab > onQ (REMOTE) page.

3.	Click MODIFY.

The Modify Remote onQ Setup page appears.

4.	In the Remote Firewall Port Mapping section, make your changes, then SAVE.

5.	Test the link.

6.	Restart protection.
