Question Remotely access a local LED board Wi-Fi

[LucasBen]

Hello! strange question here.

I have two LED boards in my business. I constantly change the content on this device... so i have to use a tablet and connect to local wifi to send messages to the board everyday.
Sometimes i'm travelling, and it's inconvenient to send other people to do this. So I was looking for an alternative to remotely access both Wi-Fi networks from my personal computer.

I have a raspberry pi 2w in case it's part of the solution.

Greetings!!

I would suggest getting a newer PI4 or PI5 and setting up a VPN server on that. Then you could run a VPN client like OpenVPN on your tablet and it would behave just like you were on the local network.

As mentioned above a VPN of some kind is your solution. Anything else is pretty high risk, you don't really want any device that does not have extremely good built in security directly accessible from the internet. Kids really love to hack those led sign boards to display inappropriate messages.

Depending on your router you might be able to use that as the VPN.

The biggest question before you look for any kind of remote access is do you have a public IP. You do not want to post it here but almost all routers will show you the IP address that is assigned to the WAN interface. Although you can look up what public/private ip means it tends to be easier to just compare the IP you see on the wan interface with a site like whatsmyip.

If they are the same they you can look at doing some kind of vpn. If they are different then things get rather tricky. There are other forms of vpn that can run without a public IP but I will avoid any discussion of the details at this time because vpn setup can be tricky without this added layer of complexity.

Use a VPN -- ZeroTier, TailScale or Netbird.

No public IP required.
