FAQ and quickstart

[Jörg Thalheim]

The kernel module is most likely not loaded.

Make sure the following command returns something.

$ lsmod | grep wireguard
wireguard             126976  0
ip6_udp_tunnel         16384  1 wireguard
udp_tunnel             16384  1 wireguard
x_tables               28672  12 xt_hashlimit,xt_LOG,ipt_REJECT,ip_tables,iptable_filter,xt_tcpudp,xt_limit,ip6t_REJECT,ip6table_filter,wireguard,xt_conntrack,ip6_tables
ipv6                  389120  151 nf_conntrack_ipv6,nf_reject_ipv6,nf_defrag_ipv6,wireguard,nf_nat_ipv6

Since you are on archlinux, did you reboot after kernel upgrade?
