Network Device with different Default Gateway (probably too complicated for you)

[NickNPSConsulting]

Hi Everyone. Hopefully this is the correct place for this. 

 

I purchased a new smart home device that is basically an RF blaster. I have some storm shutters that are remote controlled with a 433hz RF Radio Frequency and I always wanted to control them remotely when out of the house. For this reason, I bought a "MoesGo WiFi RF IR Universal Remote Controller" which allows me to send the radio frequency remotely to my storm shutters. 

 

The odd part is though that the device has a different default gateway than my router and for this reason, if I want to use it inside of my home, I have to turn off my phone's WiFi for it to work if im on my home's Wifi. This obviously took a long time to figure out... 

 

Has anyone ever seen this and have any ideas on how to fix it? Its not possible to change the IP address from within the app. 

 

Screen shot is below.

 

THANKS

What is your external IP (i.e. the one given to your modem by your ISP)? Google "my IP" if you don't know.

Damn. You’re correct - that is my external IP address. I didn’t even realize it because it used to always started with a 73. 
 

So Maybe the only way to get it to work is to reserve that IP address for that device and do a port forward? I hate doing that  because I feel like I’m opening a door to everyone.

The Top screenshot is a screen shot of my Linksys routers app. The bottom one is a screen shot of the RF blaster from within the app.

Yup. The proper way around it is to use an FQDN that you resolve yourself when inside your network to point to a local address, but resolves to your external IP when out in the world.

You can do a "hacky" workaround if your firewall gives you that level of control, where instead of allowing packets destined for [public ip]:[RC unit port] from inside your network to reach it, you redirect them back inside to the correct local address, but it's a pain to maintain if you don't have a static IP.

You've already done that, or it wouldn't work when you are off the local wifi, probably via some UPNP mechanism.

 

TBPH, If I was looking to control hardware remotely, I'd be doing it via a key only SSH session, that way whilst the "door to everyone" is visible, it's clearly locked shut.
