The server is running inside a docker, the client is running on Ubuntu 18.04. I'm not being able to send all the traffic through the tunnel. If I bring up the wg0 interface on the client and try to connect to a website, it doesn't work. However, ping 8.8.8.8 works. Any idea what is going on?
When brought up, `wg-quick` executes the following command on the client:
# wg-quick up wg1
[#] ip link add wg1 type wireguard
[#] wg setconf wg1 /dev/fd/63
[#] ip -4 address add 10.13.13.2 dev wg1
[#] ip link set mtu 1420 up dev wg1
[#] resolvconf -a tun.wg1 -m 0 -x
[#] wg set wg1 fwmark 51820
[#] ip -4 route add 0.0.0.0/0 dev wg1 table 51820
[#] ip -4 rule add not fwmark 51820 table 51820
[#] ip -4 rule add table main suppress_prefixlength 0
[#] sysctl -q net.ipv4.conf.all.src_valid_mark=1
