Thanks for correcting me. Your right there. However, if the radius software is setting the MTU the ARC will use the assigned value set by the Radius server. Which was what happened in my case and is probably happening in this one as well. Just trying to help, sorry if I misrepresented the facts. Dave Lajoie Senior System Operator North Country Internet Access dave@ncia.net Jeff Mcadams says: Actually... The defaut MTU value on the Arcs (like all other default values) is pulled from the user "default" that's defined on the Arc's. The value is only updated by RADIUS if the user profile in RADIUS has the Framed-MTU setting included. Otherwise RADIUS doesn't send the MTU value and the default from the Arc's default user is used. So, even if you're authenticating your users via RADIUS, the MTU *might* be getting pulled from the Arc's default user definition. -- Jeff McAdams Email: jeffm@iglou.com Head Network Administrator Voice: (502) 966-3848 IgLou Internet Services (800) 436-4456 - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.
