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.

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).
Here's another idea. It could be a MTU discovery problem. If you have either numbered your chassis out of private IP space or are blocking ICMP, that might be what's causing it. This might be another hint (I was hoping they were Solaris, since that would reinforce the MTU theory)... ridge.spiritone.com% telnet www.genforum.com Trying 216.15.177.242...
