Question How can I tell what is blocking access to my homepage


Hi. I have 3 webserver, 2 windows webserver (port 80 and port 8080), and one linux webserver (the main one), port 7777. I use firestarter firewall, and have opened port 7777 on linux firewall, and port 80, 8080 and 7777 on router firewall. Worked fine up to a couple of days ago.

Then I could not anymore access the linux machine webpages from work. My best guess is that my works firewall has blocked <home ip>:7777 for some reason (<home ip>:80 and <home ip>:8080 still works fine) (reason for saying that is other people can apparently still connect to the main linux web server). From home it works fine from both the windows and linux machine.

When trying to connect to the webservers using telnet, I can get something like this up for port 80 and 8080.

HTTP/1.1 400 Bad Request
Server: Microsoft-IIS/5.1
Date: Tue, 14 Sep 2004 08:38:39 GMT
Content-Type: text/html
Content-Length: 87

But to port 7777 it cannot connect.

But is it a way to know for sure if it is my works firewall that stops the connections, and not the linux machine that prevents work from connecting somehow? Can I trace it somehow?
