After doing a mon rad as suggested this is what I am seeing from the TC box with compression set to auto. 192.168.1.252 1812 192.168.1.204 1645 42 Access-Accept --------------------------------------------------------------------- Time Stamp : 22-NOV-2003 04:17:15 --------------------------------------------------------------------- Service-Type : 2 Framed-Protocol : PPP Idle-Timeout : 900 Filter-Id : virus Compression-Algorithm : 0(None) Framed-Compression : 1 With compression on the RADIUS server set to Microsoft I get this from a show session.

But, what is going to happen when someone connects with a non-microsoft client like Mac or Linux? I also noted that there is an Ascend compression and we do have one TNTMax box and I wonder if that should be a concern. Basically it appears as if the auto setting is seen as the same as the none setting. Does anyone know the numerical value for Auto? What I guess I am sending is "0" which is none. If I Knew the true value I could fix my USR dictionary, which I think came from USR. hmmm. Joel, is the auto setting working for you? If so, what does a mon rad show as the response value for it? -- Lewis Bergman Texas Communications 4309 Maple St. Abilene, TX 79602-8044 325-695-6962 ext 301 800-299-6962
