Wireguard no DNS response after connect

  • 772

I have the following setup:

  • a local DNS server (unbound) listening on 10.10.20.1
  • a wireguard server on 10.10.0.1/24
  • a wireguard client on 10.10.0.2/32 with DNS pointed to 10.10.20.1

I can connect to the server and I can see the peer:

peer: ..redacted
endpoint: 127.0.0.1:33218 
allowed ips: 10.10.0.2/32, 10.10.20.1/32 
latest handshake: 1 minute, 19 seconds ago 
transfer: 247.87 KiB received, 571.86 KiB sent 
persistent keepalive: every 25 seconds

Once connected, I can issue dig commands on my terminal and they return ok:

dig u/10.10.20.1 reddit.com
;; Warning: query response not set

Once connected, ifconfig shows my interface up:

utun7: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1420
    options=6463<RXCSUM,TXCSUM,TSO4,TSO6,CHANNEL_IO,PARTIAL_CSUM,ZEROINVERT_CSUM>
    inet 10.10.0.2 --> 10.10.0.2 netmask 0xffffffff

But, my browser does not resolve anything, nor does any other software on my system. Funnily enough, I have a VM with a Windows machine and...the internet works once connected. Any help is much appreciated.
