Porkbun Dynamic DNS and Multi-WAN

[trumee]

Hello,

I am trying to use Porkbun with Dynamic DNS. I have two WANs. I want to use my second WAN as the interface for Porkbun IP. Unfortunately Opnsense is ignoring the interface setting for Porkbun. I get the following in the log,

Code Select Expand

INFO: setting ipv4 address to 10.27.37.159 for redacted.com

WARNING: 'if-skip' is deprecated and does nothing for IPv4

It is trying to the ip from the Primary WAN interface which is a private ip.

Any way to fix this?
