(usr-tc) ****SOLVED***** Websites failing on TCHub vs Ascend... Where to start?
Problem Solved... As everyone suspected - it was an MTU problem. More specifically a problem in the MTU size. Setting the MTU size to 1500 via Radius did NOT fix the problem. After a few enlightening words from the folks at Source Technology, and the comments received via this list, I set the MTU size to 1518 in Radius AND on the Default user in the ARC itself. Everything now works flawlessly. I appreciate everyone's help. Thanks Robb Bryn

We recently have been getting numerous complaints from our users about websites that are dog slow or not coming up at all. Normally I wrote it off as "net traffic" and kept going. Recently we installed an Ascend Max product and an old Portmaster product. It appears that users dialing into the TCHub are having difficulty with specific sites where users dialing into the Ascend and Portmaster products are having no trouble at all with the same sites. 90% of all sites are accessable from the TCHub while specific sites continue to fail (starnews.wilmington.net, www.genforum.com are two examples).
Where do I begin to troubleshoot this problem? TCHub versions HARC = 4.2.32 DSP = 2.0.51 Thanks Robb Bryn - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.

How did you decide on 1518 for the MTU size? Randy McMillan PacInfo ----- Original Message ----- From: Robb Bryn <rbryn@cape-fear.net> To: <usr-tc@lists.xmission.com> Sent: Friday, March 10, 2000 11:12 AM Subject: (usr-tc) ****SOLVED***** Websites failing on TCHub vs Ascend... Where to start?

If this was the problem I experienced with users connected via ISDN routers, I think I will shoot myself. Perhaps I did not fully understand the problem here before I spouted off. Was the problem with webservers that connected via the TC or was it users who dialed in and could not move http traffic? I guess I am confused here. Samuel S.
