The one I opened a year ago the person I was subletting from at the time wouldn't allow me access to his router so I never followed up on the instructions as the point was moot. I wasn't able to make the necessary change. Even had I remembered posting that one I still would have started a new thread rather than bumping one that was a year old and based on different circumstances. 

I'm running Ubooquity on Win 10 on a desktop PC. I'm using Windows default firewall, and having had a similar issue with Plex (another media server), the first thing I checked was too see if Ubooquity was blocked there. I didn't see it listed at all, no block nor an exception, so I tried adding one but the firewall didn't recognize the .jar file so I couldn't add it. I'm not really sure if there's a diff way to add it to Windows Firewall or not. I usually don't mess with the Firewall that much. 

As for the router, I didn't need to do anything on it to allow Plex to go through, but I'm sure it uses a different port than 2202. I don't know routing well, but my level of tech understanding is pretty good. Over the last 25 years I've opened or forward ports when I had my own router (followed instructions since I don't do it every day, but routers are pretty easy, especially moderm firmware). My new roommate should trust me enough to make the change (or to make it himself for me if he doesn't want me in the router).

Cool, thanks. I'll let my roommate know before making any changes to his router. We're both good about keeping our machines and stuff pretty well protected. 

"the displayed remote IP is trivial to get anyway (open a browser while at home, type "what is my ip" in Google and pick any result)"

This answers my question. I didn't know that Ubooquity just used the public IP address of my computer so in the absence of finding that info in the interface or FAQs I didn't know where else to look. Maybe this could be added to the FAQs or to the quick setup manual for those like me who don't do any networking. 

Ok I'm looking at the pic and do NOT see the external address at all. By external, I mean if I'm on my Chromebook and not at home on my local network, what url do I put into my address bar to access Ubooquity? If it's in the screenshot above I don't see it.
