Sounds a whole bunch like you have a PMTUD (Path MTU Discovery) issue.Change the MTU on a host to be smaller and see if this fixes the issue... If it does, there are a bunch of networking tricks you can play to fix it for all of the customers. MSS rewrite is one, clearing the DF BIt on all packets is another -- these are various version of icky...

All, I know this probably isn't the best forum for this question but I'd like to rule out a network problem before I tell a customer he has a PCproblem. I run a small CLEC network that is single homed to BTN for transit. I have 3 sites all interconnected via DS3's and provide DSL services from each site. From anywhere on my network we have problemwith Ebay and versiontracker.com but only on certain browsers. IE on a windows machine can access these sites without any problems, but Firefoxon the same machine cannot open the websites (Ebay can be opened with addblocking software installed). On a Mac the only browser that works for these sites is Opera. With this knowledge I would say it issomething with the coding on the website, but if I take the same machineand connect it to another network other than mine (Verizon, SBC and local municipal wifi have been tested) everything works fine. Can anyone give me any suggestions as to what routes to take to troubleshoot this? Logic tell me that is I have reach ability and onebrowser work but another doesn't it's a software problem with either the browser or the site, but being able to take the same machine to anothernetwork and have it work points to a whole different problem. Could this be a MTU issue? Shane Owens DNA Communications Inc 601 1st Ave Rochelle, IL 61068 work (815)562-4290 ext 201 mobile (815)793-3822
