Iptables is not the best tool for packet capturing and I am not sure that capturing packets will answer your (routing) questions. You can use one of many tools, wireshark, snort, or tcpdump (to name a few). Your router may be able to track / log this as well. The details of packets is moderately complex and somewhat lengthy to expalain. Take a look at the ...


After some experimentation I was able to find the minimum required ports to resolve the agent-state: pending problem. Juju uses port 22 (ssh), juju state server uses port 17070, jujud uses port 8040. I am told this may not work with Juju set up in an HA mode because that uses different ports. Allowing these ports in ufw: $ sudo ufw status Status: active ...

This isn't actually an answer, but it was too detailed to be a comment, and may become an answer after more information is determined. When I read your post, I thought you were using your lan ip address (internal ip address), but after comparing the results of your commands vs my own, forcing me to look more closely, I see that you are trying to use an ...
