How do I configure Shorewall to use Floating IPs?
I am trying to configure my droplet’s Shorewall firewall to use the floating IP, but only for certain kinds of traffic. I’d like to use the droplet’s public IP for other kinds of traffic. Specifically:
Public IP: HTTP and HTTPS open; SMTP and IMAP closed.
Floating IP: SMTP and IMAP open; HTTP and HTTPS closed.
I’m just not sure how to do this. I know the droplet’s anchor IP and have a general understanding for how the Floating IPs work, but I’m lost beyond that.
I know that many of you are smarter than I am, so I’m hoping you can walk me through this in a dumbed-down fashion. Thank you in advance for whatever help you can provide!
