I've this weird problem. During the week the internet performance seems to be slower and slower.
When I reboot my firewall everything works normal again but after a few days it's gettings slower and slower again. At the beginning of the week it's so slow that you can't surf normally. Then again, after I reboot the firewall it's working again.
This is my netwerk situation:
first you've have to pass a Draytek Firewall (Vigor 3300v)
second you've ran into a ISA server 2004
Could it be it has something do with ISA as well, eventhough a reboot on the draytek makes it work again?
I can't find anything simular so far on EE or Google.
Please advice what steps I can take to solve this problem?
I've already contacted Draytek support but all they sending me is firmware updates but they doesn't seem to work so far.
Anyway, hopefully some of you experts has an idea?
