Hi Dave, Yes I did check it by IP address. Internal DNS - no changes at all. All other webpages work without any problem so I'm sure it can't be DNS. I tried ping on langports.fatcow.com from the Fortigate and there is no response either... -----Original Message----- From: Dave Larter [mailto:dave@stayonline.com] Sent: Monday, 11 May 2009 10:29 AM To: Juraj Benak Subject: RE: webpage doesn't worok from specific address Links work for me on the outside, maybe internal DNS? Have you checked by IP? Hosts if a Win env? -----Original Message----- From: Juraj Benak [mailto:jb@langports.com] Sent: Sunday, May 10, 2009 8:23 PM To: nanog@nanog.org Subject: webpage doesn't worok from specific address Hi everyone, I've got very unique (at least I think) problem. I have a webpage hosted on fatcow.com -> www.langports.fatcow.com <http://www.langports.fatcow.com/> The problem is that I can't access it from my computer! I'm working in an English language college and we have 2 separated networks - one for staff and the other one for students. I'm able to connect to the webpage from student's network but not from the staff's. I contacted fatcow support, they checked it from their end everything seems all right so they told me to contact my ISP. I contacted Telstra which is managing our both connections; they checked it from their end and say there is nothing wrong, they don't block anything and I should again contact fatcow. I got as well different results from tracert - 2 more hops while going through student's network (the one that works). Do you have any idea what could be wrong? I'm using Fortigate A100 as router and there has been no change last few months. Could you please advise me what program should I use to find out exactly where the problem occurs and what is the cause? Firefow return this message: Connection Interrupted. The document contains no data. The network link was interrupted while negotiating a connection. Please try again.
