pfSense

That works fine for me - give more information about the data you enter and exactly which field the "Please match the the requested format" message appears in.

Destination host should be 8.8.8.8, but the error is the same.

I have the same issue with the latest BETA version of Chrome. It works in the latest stable release, and in other browsers. This is probably a Chrome bug.

That is likely the case. Be sure to report it upstream to Chrome.

See the "best answer" here: https://productforums.google.com/forum/#!msg/chrome/MBEvipQlgyg/yeM-2XDkEi8J reproduced below, just in case:

"The messages you are getting are newly implemented html5 form validation messages, triggered on textfields with the required-attribute and input fields with custom types like "email", "date",... Other browsers will follow soon with implementing these. Browser validation is a big leap forward and you probably don't want to disable it (http://diveintohtml5.org/forms.html#validation).

If you actually do want to disable the form validation, don't rename all "required" attributes, but simply put the "novalidate" attribute in your form tag."

So from Jon Gerdes explanation, this should be adjusted to "Bug" as pfSense is using invalid HTML5? Just not apparent on browsers that are yet to support HTML5 validation.

It is not a bug in our code. It is a bug in Chrome that we have worked around by removing escaping from the regular expression for validation. Chrome is not properly obeying the Regular Expression specification.
