If that's not a typo, those pools each contain only two IP addresses... That would cause problems. Charles

I'm not quite sure where the setting is for free radius Kirit. I'm sure you could do a google search and get that fairly quickly. If you know where your free radius config is try grepping for 'mtu' and see what you find. I know if you do a monitor radius on the hiperarc you can see the "framed-mtu" that it's using. I'm pretty sure you'll find a value other than 1500 for those that are causing you troubles. Many people have had this issue at one time or another. http://mailman.xmission.com/pipermail/usr-tc/2003-December/008216.html Once you get the mtu setting changed in your free radius config if you're still having issues let me know.

Hi All: I did the following two things: (1) updated raddb/user and added a value of 1515 for the MTU (2) Added a local DNS server on one of the server and the problem seem to go away. I have done a tracert and the response time is about 38ms instead of 140ms for each hop. I will know by tomattor if it is still working. Thanks for everyone's help.

Once you get the mtu setting changed in your free radius config if you're still having issues let me know.

Todd /etc/raddb/users is where you would normally find it. Probably in a DEFAULT section if it seems to happen to everyone.

Hello:

TC1000 1-HiPer NMC 2-HiPerARC 10-Hiper DSP

Got a strange problem. Several of our dial-in clients are complaining that they can dial-in, are authenticated and can go to various web sites BUT NOT to any 'Microsoft' or 'MSN' web site.

For several months, our system is the same with no changes. Two weeks ago, we had was a large number of double bounces on our mail server.

This problem started about a week ago.

Has anybody seen the same problem?

Thanks.

Yes, it turned out to be the MTU value. After I changed it to 1500, the problem went away. Thanks everybody.

Subject: RE: [USR-TC] MS is not displayed The only thing similar to this in my experience is an incorrect MTU setting (usually in your radius) config. I believe the TC's default to something else but if they (or your radius server) are not set to 1500 MTU your users will have problems going to Microsoft's site among a few others. Anything similar on your end Jim as far as double bounces with your mail server or anything else that you can point to that may have changed recently in your network (i.e. auth settings) Todd -----Original Message----- From: usr-tc-bounces+berto=core.com@mailman.xmission.com [mailto:usr-tc-bounces+berto=core.com@mailman.xmission.com] On Behalf Of Jim Johnson Sent: Saturday, January 27, 2007 2:14 PM To: Discussion relating to the 3Com/US Robotics Total Control modem systems.
