Hi all,
I have a sophos utm 9 with the lastest UTM. I have a question of comprehension.
Everything on the UTM is deactivated. The only thing "on" is firewall.
Here, I have the default rules for email web, etc. nothing special.
But I wonder, why certain specific domains are blocked (connection reset) randomly, but they work correctly over mobile access.
As I understand a firewall, its just handling the ports, not blocking special or specific domain names.
One of the blocked domains is for example: https://www.openproject.org
Today the domain works, yesterday it was blocked.
Any hints on that?
What I also really hate is, that the UTM is making my network "really" slow.
When I call a certain website over mobile (4G) its there in lets say one to two seconds.
If I call the same(!) website over my network ( PC -> netgear switch -> UTM -> cable modem) it takes about 10 to 20 seconds and mostly running into timeout.
Even though my cable connection is 100Mbit. everything is in subnet 192.168.0.0
Any ways to speed that up?
Those prpoblem do not really help to become a fan of sophos firewalls.
