Your 3com may be set for 1514, but what's being set by the radius server? That's where the problem usually is. Seems like RADIUS servers that have that set by default have it set to something like 576, which will cause the problems you're describing. -----Original Message----- From: Kirti S.

Subject: RE: [USR-TC] Web Connection problem That kind of sounds like an MTU problem we had in the past. Is your PPP MTU set at default? I believe that is 1514 -----Original Message----- From: usr-tc-bounces+adam=semo.net@mailman.xmission.com [mailto:usr-tc-bounces+adam=semo.net@mailman.xmission.com] On Behalf Of Kirti S.

Subject: [USR-TC] Web Connection problem Hello List: Please /help/ with this strange problem. I am testing a 3COM box. When I dial-in onto 3COM & connect to http://www.tib.com (which is our web site), it connects with no problem. Similarly, I can connect to numerious other web sites. However, when I try connecting www.msn.com or www.riteaid.net, it never connects. There are few other web sites with the same problem. When I try to sign-in into MSN Messenger, same problem. Such connection can not be made. I have spent the last two days on this problem trying to figure out what to do. FYI, I can issue: HiPer> resolve name msn.com and it does resolve the address. Similarly, I can resolve address of 'riteaid.net' and just about any other web site I have tried. I have disabled 'cache' & ncache' on HiPer ARC. I have no idea what else to do. Please /help/ or give suggestions!!\ FYI, I have no such problem with our production system which uses a different type of dial-in modem bank (instead of 3COM).
