You must ensure that WireGuard kernel modules are available on every node, both servers and agents, before attempting to use the WireGuard Flannel backend.


CLI Flag and Value | Description
-------------------|------------
`--flannel-ipv6-masq` | Apply masquerading rules to IPv6 traffic (default for IPv4). Only applies on dual-stack or IPv6-only clusters. Compatible with any Flannel backend other than `none`. |
`--flannel-external-ip` | Use node external IP addresses as the destination for Flannel traffic, instead of internal IPs. Only applies when --node-external-ip is set on a node. |
`--flannel-backend=vxlan` | Use VXLAN to encapsulate the packets. May require additional kernel modules on Raspberry Pi. |
`--flannel-backend=host-gw` | Use IP routes to pod subnets via node IPs. Requires direct layer 2 connectivity between all nodes in the cluster. |
`--flannel-backend=wireguard-native` | Use WireGuard to encapsulate and encrypt network traffic. May require additional kernel modules. |
`--flannel-backend=ipsec` | Use strongSwan IPSec via the `swanctl` binary to encrypt network traffic. (Deprecated; will be removed in v1.27.0) |
`--flannel-backend=none` | Disable Flannel entirely. |
