I have a new Sophos XG115 without any firewall rule besides the default one, with a basic license, default webfilters and no IPS activated. It is connected to a router and to a internal switch. Both interfaces have 1000 Mbps - Full Duplex Auto-negotiated. When I make a speed test I'm at around 30 Mbps Up and Down. But when I try to open a website, it takes 15 seconds or more. Before we set up the firewall it was much faster. Also over the old WLAN, who is not behind the firewall it is much faster as well.
Any idea what could cause that?
Thanks for your reply!
No they didn't have a firewall before. They are very small and basically just wanted something to provide a seperated access to the internet in case they want to sublet a part of their office.
I updated the definitions from 8.x to 9.x. I will make some performance tests tomorrow.
please try running two speed tests from different devices at the same time. This might be just require disabling some of the IPS functions.
Also check you IPS -> DoS tab and see what results are displayed against which IPS function.
Thanks for your reply.
In DOS everything is disabled. And the other features only come with higher subscriptions as far as I know.
check dos attack and dos spoofing, they are seperate functions even though they might look the same.
both of them are disabled
I checked everything for udpates. But unfortunately this didn't solve anything. I also tried to deactivate the AV and IPS Service but that didnt help too.
on the second screen shot, you have only shown the top part of the page, there are more settings below that might be having an effect.
Hi,I booted to the firmwarew SFOS 16.05.3 MR-3 which came preinstalled and here the performance is fine. So it seems there is a bug or something in the new version.
We just deployed the XG 210 firewall and i am experiencing this issue of slow internet speeds. I have disabled all the features but nothing seems to change.
What can be a solution to this and yet if i connect directly to the ISP the speeds are okay?
Did you check DNS?
