for a while now I have problems connecting qubes to the internet.
The internet works fine in sys-net and sys-firewall. I checked this via
ping 188.8.131.52 and
When I connect any qube to sys-firewall, I don’t have internet access.
However my VPN-gateway which is derived from (GitHub - QubesOS-contrib/qubes-tunnel: Integration of vpn tunnels for Qubes OS) connects and when I route the traffic like sys-net->sys-firewall->vpn-gateway->personal then I can connect to the internet. But it seems to be very slow which happens rarely for this vpn provider.
I’ve had this issue previously and was able to fix it wih
this (No DNS in inheriting VMs after enabling fedora-35 template's fedora-updates-testing repo and updating · Issue #7429 · QubesOS/qubes-issues · GitHub).
But now the same issue occurs and I don’t know what to do.
I appreciate any help!
Let me know if you need some logs or other further information.
