TP-LINK R605 loopback/Hairpin NAT problem

Model: ER605 (TL-R605)  
Hardware Version: V1
Firmware Version: 1.3.0

Hey I have a question, because I have a router R605 to it connected 2 fiber optics under wan and wan1


Under wan2/lan and wan3/lan I have a NASA DS420+ connected and under wan4/lan I have my PC connected.

 

The problem is that I have hooked up everything in OMADA to which I have installed on NASA, I think it doesn't really matter, but I will add that way.

 

and now the problem is that I have a public IP address to which I can enter from outside but I can not enter it inside this lan network.

 

That is to say, if I am at home I can enter NASA only under IP address 10.0.0.240 but I can not from IP. 123.123.123.123 (example)

 

If I am away from home I can safely enter from 123.123.123.123.123 (example)

 

Soft:
Omada - the latest that is available
TP-LINK 605 1.3.0 - also the latest, I changed to 1.1.1 to 1.2.0 also gave nothing.

 

Do you know perhaps how to solve this problem?

 

I will add that in another house I had fiber from Orange with a public IP address and this problem did not exist.

Read the changelogs

 

EDIT:  nvm you have the V1... Junk it and buy a V2.

I wrote to my network provider, specifically to the person who deals with public IP addresses, I learned that they changed something in the local configurations, I have to wait a few days they will determine if it is on their side.
