This is a networking question, not a Python question. You'll probably
get better results on a forum focused on networking.

Your router's address, 10.10.9.2, is another RFC 1918 address, just
like 192.168.1.3. Are you attempting to connect from elsewhere on the
10.* network, or elsewhere on the internet? If the latter, you
probably have to deal with a second level of NAT.

The easiest way to test: Can you talk to (eg ping) the router,
10.10.9.2, from the computer that's unable to reach your server? If
not, there's your problem.
