Proxying based on a regex

[Charles Plater]

I'm trying to configure our FreeRadius (2.1.9) server to proxy based on the format of the ID. I have a working regex that determines the domain to which the request should be sent, but I'm having a hard time figuring out the syntax of the proxy statement. Here's what I've tried:

if (User-Name !~ <REGEX>) {
	proxy: domain.name
else {
	proxy: LOCAL
	}
}

FWIW, I can successfully authenticate do the "domain.name" realm by using userid at domain.name.

Can anyone offer any suggestions? Thanks in advance.
