DNS Timeouts while using Unbound

[Vuurmuur]

I'm using unbound as an intermediate cache which is advertised through DHCP. But I'm getting DNS timeouts while using Unbound:

Code: [Select]

>nslookup google.com

Server:  opnsense.xxxxxxxx.xxx
Address:  xxx.xxx.xxx.xxx (opnsense box address)

DNS request timed out.
    timeout was 2 seconds.

When I query 1.1.1.1 directly I'm receiving a quick response:

Code: [Select]

>nslookup google.com 1.1.1.1
Server:  one.one.one.one
Address:  1.1.1.1

I already have 'Forwarding Mode' enabled, changing this does not yield different results.
I have tried disabling Suricata but this does not have any impact.
Successive requests still result in DNS timeouts, the result should be cached on first query if I'm not mistaken.

Any suggestions on why this is happening and how to fix it?

Apparently I had one of the options for hardware offloading still enabled.
This didn't cause issues before 20.7 but disabling all hardware offloading fixed the issues.
