pfSense

When adding an URL alias with multiple URLs, only the last URL ever gets resolved.

Expected behavior: every URL should get resolved into an IP address lists, and the resulting alias should be the union of all the IP addresses from the lists.

I have described the issue in the Forums too, where you can read some debugging steps and see more screenshots: https://forum.netgate.com/topic/159803/failing-to-add-url-alias-with-mixed-ipv4-and-ipv6-addresses
