How to setup blynk local server with port forwarding in the router

Okay, so you do have a Double NAT situation because the second hop is to 10.10.100.1 which is a private IP address.

This means that port forwarding won’t work, unless you are able to get your ISP to provide a static IP address that is outside of their Double NAT system.

As I said, a static IP will only be worth buying if it is outside of the Double NAT system. You still need the port forwarding, which is set-up now, but you don’t need the DDNS account and updater.

ok, now the conclusion is that I will have to get a static IP from the ISP which is outside their DOUBLE NAT configuration.
so, now let me get back to you as soon as I get a static IP
.

so,if i get my static IP then port forwarding is not going to be a trouble at all right?

From what you’ve shown in the screenshots, you’ve already set it up correctly.

Pete.

which screenshots to be specific?

Pete.

ok, sir, I will get back to you as soon as I get my static IP.
