Table 111.

Key Name | Value Type | Default Value | Value Description
--- | --- | --- | ---
    fwmark
    uint32
    0
| The use of fwmark is optional and is by default off. Setting it to 0 disables it. Otherwise it is a 32-bit fwmark for outgoing packets. Note that "ip4-auto-default-route" or "ip6-auto-default-route" enabled, implies to automatically choose a fwmark.
    ip4-auto-default-route
    NMTernary (int32)
| Whether to enable special handling of the IPv4 default route. If enabled, the IPv4 default route will be placed to a dedicated routing-table and two policy routing rules will be added. The fwmark number is also used as routing-table for the default-route, and if fwmark is zero, a unused fwmark/table is chosen automatically. This corresponds to what wg-quick does with Table=auto. Leaving this at the default will enable this option automatically if ipv4.never-default is not set and there are any peers that use a default-route as allowed-ips.
    ip6-auto-default-route
    NMTernary (int32)
| Like ip4-auto-default-route, but for the IPv6 default route.
    listen-port
    uint32
    0
| The listen-port. If listen-port is not specified, the port will be chosen randomly when the interface comes up.
    mtu
    uint32
    0
| If non-zero, only transmit packets of the specified size or smaller, breaking larger packets up into multiple fragments. If zero a default MTU is used. Note that contrary to wg-quick's MTU setting, this does not take into account the current routes at the time of activation.
    peer-routes
    boolean
    TRUE
| Whether to automatically add routes for the AllowedIPs ranges of the peers. If TRUE (the default), NetworkManager will automatically add routes in the routing tables according to ipv4.route-table and ipv6.route-table. If FALSE, no such routes are added automatically. In this case, the user may want to configure static routes in ipv4.routes and ipv6.routes, respectively.
    peers
    array of 'a{sv}'
| Array of dictionaries for the WireGuard peers.
    private-key
    string
| The 256 bit private-key in base64 encoding.
    private-key-flags
    NMSettingSecretFlags (uint32)
| Flags indicating how to handle the "private-key" property.
