Hello!
I seem to be having a weird network-related problem when I take my Macbook Pro to work and connect it to our office LAN:
The Macbook gets an IP via DHCP of the office-(firewall-)router and seems to be connected properly to the network but websites will not load (progress bar stuck at 1/5) if they have an http- or https-adress. Ftp-adresses are loading fine, mail (sending and receiving) is also working fine. I can also ping/traceroute websites and IP-adresses without any problems, but they wont load in any browser (I've tried Safari, Firefox and Chrome).
I can reproduce this on any Mac OS X-device available to me (so far I have tested three different Macbooks) while Windows-devices are working fine.
I have tried different DNS-Servers, reset the network settings, rebooted the devices countless times, disabled IPv6 and tried every other trick I could find via multiple google searches without any success. Our network-expert tells me the office-firewall shouldnt be the problem, a claim that is also supported by the fact that Windows-devices are working fine with the exact same settings.
Does anybody have any idea what the culprit might be or heard of similar problems? I'm out of ideas. 🙁
Thanks for reading the long and confusing description of my problem! I hope somebody can help ..
