Hi,
We host the Vault on RHEL with firewalld daemon using currently. But we are planning to switch to UFW in future.
I didn’t see any requirement on this area from official document.
So is the UFW also supported (or even preferred) for Vault?
Are there any additional configuration for the UFW after it swtich from firewalld?
Your choice of firewall and/or network ACLs doesn’t change the required ports.
The basic, and defaults are listed here:
If you changed any of the default ports in your configuration, you will need to modify those in your firewall/nacl rules.
Also, if you use something like KMIP, that will need additional rules not listed above.
