![]() The FRDM board normally comes up in original code as a 'web server'. Also the port I put on the request is 80 (http). I see WireShark captures that the SYN packet was sent out - both src and dest IP addresses are correct. Ip -net $ns1 addr add 10.11.11.1/24 dev veth1 NOTE that FRDM-K64 uses LWIP protocol stack, 'around' TCP/IP stack. Ip netns exec $ns1 iptables -A INPUT -m state -state established,related -j ACCEPT # add a rule inside NS so we enable conntrack (the traffic is forwarded over a VPN) When I observe the Connections page of the IP Firewall, I see the timer downcounting to zero even when there is matching traffic. Ip netns exec $ns2 sysctl -q 2.forwarding=1 state Established, Related and a rule that allows traffic outgoing from my LAN.
