SchefferKD / Wireguard with two "default" routes
Created August 26, 2019 08:16
Wireguard allow in "AllowedIPs" only uniq networks. My solution: I split the 0.0.0.0/0 in two more specific Networks (0.0.0.0/1 and 128.0.0.0/1).
[Interface]
Address = 192.168.0.2/24
PrivateKey = <ClientPrivateKey>
Table = off
#server1 - primary connection
[Peer]
PublicKey = <server1_PublicKey>
Endpoint = <ip-server1>:<port-server1>
AllowedIPs = 0.0.0.0/1, 128.0.0.0/1
