IMPORTANT: This change may affect customers who have restrictions on their outbound firewalls. If you think this might apply to your business, please ensure the IT Team (or equivalent) are aware of this article.
Throughout the month of June 2025 planned Volume Remote server maintenance work will be carried out. This maintenance work involves the upgrading of production servers to maintain reliability and security.
The maintenance work is planned for Monday 9th June, Monday 16th June and Monday 23rd June. During these periods there will be a slight drop in Volume Remote access between 8:00pm and 9:00pm.
As part of the maintenance work, the IP address used to connect to the Volume Remote Middle Tier servers will be changing. This change may affect customers who have restrictions on their outbound firewalls. If this change applies to you, it is expected that an already existing outbound rule for port 4077 will exist for IP addresses 178.159.10.174 or 31.132.3.26. Please update your outbound firewall rule to also allow access to the destination server IP address 31.132.4.142 for TCP port 4077. From July onwards, IP addresses 178.159.10.174 and 31.132.3.26 can be safely removed from the outbound firewall rules.
Please ensure this update is applied before Monday 9th June.
As a reminder, customer firewalls should contain the following outbound rules for Volume Remote to function correctly: -
Primary Site: -
TCP port 1433 to destination server IP address 178.159.10.173
TCP port 4077 to destination server IP address 178.159.10.174 or 31.132.3.26. To be replaced with IP address 31.132.4.142 throughout the month of June as per above.
Secondary Site: -
TCP port 1433 to destination server IP address 178.159.11.246
TCP port 4077 to destination server IP address 178.159.11.248
If you are unsure whether these changes may affect you/your site, please get in touch with your own IT in the first instance.
