I have a problem with the availability of server from the outside (from local network all works perfect). A key problem is the http, where the requests are carried out but only if the response is less than a certain number of KB. - if accessed via browser from the outside, only the request less than or equal to 4KB are responsed - if access via the wget from the remote server, the requests are successful only if they are less than or equal to 256bytes - if access from php (via file_get_contents function) the response is max 256kb (if the request to a dynamic php file, if the request to a static html file, only 128kbs)

Examples of succes and failed attempt:

# wget http://tamtam2.izdelava.si/a.html
--12:46:08--  http://tamtam2.izdelava.si/a.html
           => `a.html'

A similar problem is also with the FTP connections, for example, where the connection is interrupted if accessed to the directory that contains too many files or subfolders. I have tried with different versions of apache (and even ftp servers) but the result was always the same. In the IIS server the problem is the same.

I guess that the problem is somewhere on the level of rutinga / firewall but I failed to determine anything concrete. Does anyone have any idea what could be the problem?
