Hi Aaran

Thank you for that. You are right, it does look nasty :)

I must have missed a step somewhere, as I am seeing this in the debug when using your ulang code.

++++++? if ("%{hex:ADSL-Agent-Remote-Id}" =~ /^....([0-9a-f]+)$/)
WARNING: Unknown module "hex" in string expansion "%"

There doesn't seem to be a hex loadable module.

I am using freeradius 2.1.8

Cheers.
