I’ve a UTM virtual appliance running at home for almost 5 years. Never got a problem.
Just a few weeks ago I installed ownCloud so I can share files on my smartphone, etc.
ownCloud syncs the files. My internet connection is 40 down and 4 up.
The Problem
When I use the ownCloud client outside my LAN, example at work, I got really really slow
download speed of 15 – 30 KB/s. This problem also excists with any webbrowser.
When I upload from my work to home I got my full upload speed of my provider, 4Mb.
When ownCloud starts syncing I see that it starts on the maxium download speed and then
quickly drops to almost nothing.
On my LAN I got no problems, there is it the maxium up and down. So ownCloud must be
working good. Because of that I think it’s something in the UTM.
What I did so far
I made 2 rules DNAT and SNAT.
SNAT : For traffic from “IP ownCloud server” --> service “443” --> going to “Any” --> service “MyPortNumber”
DNAT : For traffic from “Any” --> service “MyPortNumber” --> going to “ExternalWAN-IP” --> destination “ownCloud IP” à service “443”
I also tested true a VPN connection where I connect the ownCloud client with the IP of my ownCloud server and the download speed is there also bad. But the upload is the maxium. Also when I download
a file from a share on one of my servers I got the full download speed.
I see also no performance issues on my server or on all the clients that are running on it.
I tried to turn off logging of the rules, turn off Intrusion Prevetion.
Anybody a clue on whats going on?
