Hi!I still have some problems uploading certain tiles. I get one of the following messages: 502 Bad Gateway or 500 read timeout It has nothing to do with the file size (sometimes just 10kb). If I copy the file into the upload-Directory of another client in a different location it will be uploaded at once.Finally, I searched my logfiles und found messages from the firewall on my DSL-router (a vigor):Jul 16 00:22:52 xxxxx Vigor: IM Block(QQ) lan 192.168.xxx.xxx,53087 -> 137.110.119.130,80 PR 6 len 20 1442 I see these messages from the time of the first try to upload the file until the file is removed.Wikipedia tells me, qq is a instant messenger. As far as I know, there is no IM installed on this (Debian) machine.So why would my router consider an upload as an instant message?
Your Firewall is badly broken, because it confuses random source ports with destination ports.
Basically it's how TCP/IP works. you connect from a source port (pseudo-randomly chosen from available ports) to a destination port (like 80 for http, those are defined and by no means random).
If your firewall can't tell the difference it has a severe bug. -- Dirk-Lüder "Deelkar" Kreie Bremen - 53.0952°N 8.8652°E
