The procedure for adding new firewall rules is as follows:
Note: If there is a POD maintenance scheduled on the load balancer B2C Commerce cannot perform any firewall changes ~18 hours before the maintenance window and ~18 hours after the maintenance window - this also includes emergency updates.
Firewall Q&A
Which ports are open by default on the B2C Commerce platform?
TCP ports 22, 80, 443, and 587 are open by default on B2C Commerce and do not need Firewall Rules created. Port 21 (ftp) is not open by default, but a request can be made and it will opened.
How long does it take to allowlist an IP address?
Firewall updates take two to three business days to be done. Changes go through an internal approval process.
Do web service connections require firewall rules/allowlist requests?
Yes, all outgoing requests on custom ports other than ports 22, 80 and 443 are blocked by the firewall and require specific updates on the B2C Commerce side.
What if the connection attempt is still failing after the firewall rule was added?
It is then likely that the request is blocked on the remote side, either by a firewall there or on the application layer. The outgoing IP of the POD then needs to get allowlisted on the the remote end. See the articles below for details.
