OK, with daily basis I meant as with some periodical scan, as oppose to some one time scan for some specific purpose.
I agree with you that it doesn’t sound like a firewall issue, but JFYI, Kerio is “going down”. Is not going to be developed anymore, and some users recently have reported some little problems (which doesn’t mean it is a bad product). I would suggest searching for a new firewall anyway, and independently of the issue you described here.
