Hello guys,
I am losing my mind over this issue:
I am running Endeavour OS on my laptop and I need to connect to my OPNSense through wireguard, but the performance has been terrible, DNS resolution to be precise. I think this is related to a specific configuration to either NetworkManager or openresolv, because the same configuration file works fine on Android or Windows devices.
My suspicions are that because I am using two piholes that are on the same network of the OPNSense router (and I have a few firewall rules redirecting every DNS traffic to them), there is a conflict somewhere. I have also tried to mess around with the MTU size, but to no avail.
Here is my config file:
[Interface]
PrivateKey = ****************************************
Address = 10.10.10.5/32
DNS = 192.168.0.11, 192.168.0.12
MTU = 1420
[Peer]
PublicKey = ****************************************
AllowedIPs = 0.0.0.0/0, ::/0, 192.168.0.0/24
Endpoint = ******************:51825
Any ideas? Thank you.
I was dealing with wire guard dns issues recently. What is the interface set to in settings > DNS? I had to set mine to permit all origins for pihole to play nice with wireguard.
Oh I think that can be an issue! It was only allowing local requests, one hop away. Perhaps I should configure for eth0
EDIT: I think it worked! Only the secondary DNS server was set to listen to eth0, so perhaps the delay was caused by that. Many thanks!
