to the [Interface] Section!

i deleted my tunnel, edited the conf file by adding the "Table=off" statement and import again.
Now i have a persistent Tunnel to my VPS, and can access this tunnel by selecting the interface like this:
# got my isp ip
curl ipinfo.io/ip
# got my vps ip
curl --interface wg1 ipinfo.io/ip
