Ok, that was my understanding also. The point is that adding a static route has an interface on it which seems to be redundant. It doesnt matter which interface is chosen, does it?
if polling fixes the problem, you know it was interrupt related.
It didn't solve. I will change second eth wich is Netgear GIGA card for 10/100 Intel and try then.
My be this reltek based card is buggy when VLAN's are involved.
You could activate https and change the port to 80 but then you still need to type the https (and additionally :80 because it's not standard http). But i dont think it's possible to just redirect the request. You would need a page on port 80 that has a redirection to the https page on another port. And afaik the webgui cannot run on multiple ports.
I reinstalled all and i restored the settings from the xml backup file.
I had to shutdown it and i wanted a another way to do it without putting the system down.
Anyway i got the problem solved.
