Setting up port forwarding with linksyssmartwifi.com for Duck DNS

Configuration
1

I’m having trouble getting my router to forward myname.duckdns.org:8123 to my Pi3 running hass.io. I’ve seen a lot of different guides on this, but it sounds like all router software have a slightly different way to do it. Here’s what I know:

  • I have a Linksys WRT1900ACS that comes with the linksyssmartwifi.com interface. (I’m hoping this is a fairly common interface that someone can help me navigate.)
  • myname.duckdns.org is correctly forwarding to my router admin page. When I add the port (myname.duckdns.org:8123), Chrome gives me: “This site can’t be reached” ERR_CONNECTION_REFUSED
  • In linksyssmartwifi.com, I attempted to set this up by going to Security -> Apps and Gaming -> Single Port Forwarding and set up a record with the following details: App name: hassio.local / External Port: 8123 / Internal Port: 8123 / Protocol: Both / Device IP#: my Pi IP / Enabled: checked – does this sound like the right place and details to anyone?
  • I’ve verified that I’m entering the correct IP for my Pi by browsing to that address and logging in to the interface.

Any advice? Anyone with a linksys router using the linksyssmartwifi.com software set this up before? Thanks!

Can you access the router via 192.168.1.1?

Yes. I get that same Linksys Smart-Wifi interface from that location.

Thank you. I already have a configured router and am familiar navigating the interface. But where do I go to forward DuckDNS? I’m looking at the following:

On a wim, I tried connecting to myname.duckdns.org:8123 while I was at work, and I can access it now. I haven’t changed any settings though, so I’m assuming I just have an issue with myname.duckdns.org:8123 working within my home network. Any ideas what that could be? I’d love to be able to use the same link regardless of where I am.

Your router needs to support loop-back in order to allow connecting to an internal address via the public domain. Most home routers do not. As a work around, create a custom DNS entry (if support by your linksys) where myname.duckdns.org points to the internal IP of your Pi3.

When I am at home I connect direct to the ip/port of the computer running HA and use the duckdns address when I’m out or at work.

Home: 192.168.X.XXX:XXXXX
Out: XXXX.duckdns.org:XXXXX

Thanks for your feedback. I was able to get it to work by disabling “Filter Internet NAT redirection” under Settings > Firewall tab > Internet filters

I’m unaware of the security consequences, so I’m not sure if this is a good solution for the long term, but I thought I’d respond anyway. myname.duckdns.org:8123 now works from in or outside the network.

There is a way you can send a screenshot of your firewall settings?
I have the same issue and I my Filter Internet NAT redirection is disable.
