Hi Gareth, Could you please also check that all the following are set to 1, I appreciate you've confirmed that the one for tcp is set to 1, and by default the one for raw is also set to 1:
sudo sysctl -a | grep l3mdev If not, sudo sysctl net.ipv4.raw_l3mdev_accept=1 sudo sysctl net.ipv4.udp_l3mdev_accept=1 sudo sysctl net.ipv4.tcp_l3mdev_accept=1 Thanks Mike
