Hi, I have a total strange problem: in my network are several computers. And two of them - normally used by one person - have problems accessing the server. One machine runs Xubuntu and the other is a tablet running Android. nslookup on the machines work. And sometimes I can also browse websites beeing on the ispconfig 3 server. But ... very often, there is the problem, that I can't open any domain hosted on this ispconfig server. At the same time the machine in question can open other websites without any problems. Also a telnet domain.com 80 does not work. I tried accessing the server (domains, telnet) from my MacBook at the same time the other users has the problems. Here, I find no problems. The same is for reaching the domains using a smartfone. ALL machines are within the same network and use the same public IP!!! And all machines go through the same router (a FritzBox). Anyone an idea?
