<div><div dir="ltr"><font face="Tahoma,sans-serif" color="#000000">Dave,<br><br> It is very hard if not impossible to port check a udp port remotely. Port checkers will show erroneous info on udp ports. tcp ports should show correctly on a port checker. You are right in checking a TCP port like http or ssh and see if they work. The BBB has httpd running for lsnodes but if you simply send a web browser to your BBB's local IP address you will get -<br></font><br><font face="Tahoma,sans-serif">THIS IS A TEST !
<br><br>If you are not using port 80 then make sure you put the port in the url -<br><br>Ex - <a href="http://192.168.1.100:8080" target="_blank">http://192.168.1.100:8080</a><br></font><font face="Tahoma,sans-serif"></font><font face="Tahoma,sans-serif"><br></font><font face="Tahoma,sans-serif">on the web browser. If you have port 80 (or whatever you have changed it to) forwarded to your BBB anyone on the Internet should also get that by going to your public IP. </font><font face="Tahoma,sans-serif"><br></font><font face="Tahoma,sans-serif"><br></font><font face="Tahoma,sans-serif">You could also setup ssh which defaults to port 222. If you port forward 222 (or whatever you have it set to) anyone on the Internet going to your public IP at that port should get your login. No need to actually login. If you get the login it is working.</font><font face="Tahoma,sans-serif"><br></font><font face="Tahoma,sans-serif"><br></font><font face="Tahoma,sans-serif">You might also check and make sure that both of you have each others node entry in your rpt_extnodes file.
