matching accounting packets in the acct_users file

i would like to filter off interim accoutning packets from specific domains to a different proxy target - as follows... # interim/status/alive accounting records are actually sent to the processing domain DEFAULT User-Name =~ "@.*\.abc\.co\.uk$", Acct-Status-Type == Alive, Proxy-To-Realm := "filterradius" # following is used to map subdomains of *.easynet.co.uk # to be proxied according to the realm easynet.co.uk DEFAULT User-Name =~ "@.*\.abc\.co\.uk$", Proxy-To-Realm := "abc.co.uk" however, the first rule is never matched when i send packets with the following attributes: Attributes: Acct-Status-Type = Alive, User-Name = "test@xyz.abc.co.uk" do i have the syntax wrong? tariq
