General Discussion / Re: Slow Chrome on Windows 11 behind Opnsense firewall

« on: January 03, 2024, 03:02:19 pm »

Hello Bart,

I did make a Wireshark trace and didn't spot any obvious problems.
So I had to dig a bit deeper 
Then I saw a lot of DNS requests for wpad.[mydomain.com] and they were actually being forwarded to my domain registrar for resolving. Because that probably doesn't resolve to anything that makes sense to Windows, I can imagine that slows things down quite a bit.

I now manually override the wpad subdomain in unbound DNS on my Opnsense box and that seems to solve the issue. The Opnsense documentation actually states that there is a "WPAD records" button in the unbound DNS config, but I couldn't find it. Has it been removed ?

General Discussion / Slow Chrome on Windows 11 behind Opnsense firewall

« on: December 29, 2023, 08:45:13 pm »

I recently installed an Opnsense system at home as my home network firewall.
I am working with the default settings for the firewall and most other parts of OpnSense.
For some reason when I now open a new website in Chrome on  Windows 11, it takes a couple of seconds to load the initial website , but is quite fast after that. When I do the same on a local Linux PC, the website loads almost instantly.
When I connect directly to the Internet,  the problem disappears, so it somehow seems to be related to the OpnSense gateway.

Could it be a firewall issue?
Did anyone notice similar behavior and does anybody have any ideas how I can resolve this?
