It's trying to do a regex match against the packed (32-bit) IP address, not against the ASCII string describing the IP address. That can easily be fixed. But in any case, you *don't* need to use attr_rewrite for this. Just put the following into the pre-proxy section, instead of the "fixcboss6" line: ... if (proxy:NAS-IP-Address == 172.29.51.24) { update proxy { NAS-IP-Address := 172.26.64.100 } } ... It's that easy. See "man unlang" for details. Alan DeKok. - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html
