Split tunneling with VyOS and Mac client

[Skyler Mäntysaari]

Dear list subscribers,

I have tried to find actual documentation on split tunneling with 
Wireguard, but couldn't find really any actual examples on it. IPv6 
works, but my IPv4 connection does not work after connecting the VPN and 
I only want IPv6 to be tunneled. IPv4 should use the non-vpn gateway.

Pinging for example Cloudflare's DNS does not work, I get timeouts.
This is to give myself IPv6 connectivity when the actual network lacks it.

Server config:
  address 2a01:xxx:xx:f80b::1/64
  address 192.168.99.1/24
  peer sky-mbp {
      allowed-ips 2a01:xxx:xx:f80b:bad:c0de::1/128
      allowed-ips 192.168.99.3/32
      persistent-keepalive 15
      pubkey <censored>
  }
  port 51820

Client config:
[Interface]
PrivateKey = <censored>
Address = 192.168.99.3/32, 2a01:xxx:xx:f80b:bad:c0de:0:1/128
DNS = 2a01:xxx:xx:f80b::1

[Peer]
PublicKey = <censored>
AllowedIPs = 192.168.99.1/32, ::0/0
Endpoint = server_ipv4_address_censored:51820
PersistentKeepalive = 15


Best regards,
