Model: TL-R600VPN  
Hardware Version: V4
Firmware Version: 4.0.3 Build 20190227 Rel.48206

Hello all, 

       I have configured TL-R600VPN at a site. That router has a static public IP address (let's assume 1.2.3.4) and I can access that router from the Internet with that IP address. Private network range is 172.21.0.0/16 and we have a internal server 172.21.6.1/16 which is a local web server. 

 

Now our requirement is that we have 2 additional public IP address (1.2.3.5 and 1.2.3.6). So we want to bind 172.21.6.1 to 1.2.3.5. 

 

So if anyone access from the Internet with 1.2.3.4 then router should be accessed and if anyone accesses it with 1.2.3.5, then internal server 172.21.6.1 should be accessed.

 from Internet, http://1.2.3.4 ---> Router page 

                        http://1.2.3.5 ---> Server Web page

 

I  implemented One-to-One NAT for this. And when I checked from whatismyip.com website, it showed me my 1.2.3.5 translated IP. 

 

But when I tried to access from Internet, http://1.2.3.5, Still i get router page. 

 

 

Please help me in this.

 

Regards, 

Patel Sagar

Dear @sagar002100,

 

You may upgrade the firmware of the TL-R600VPN router for checking.

And refer to the FAQ to configure One-to-One NAT. https://www.tp-link.com/support/faq/2153/

@Fae

Hello,

 I Configured one-to-one NAT for my web server and it's working fine when I access it from the Internet with its public IP address. But now I am facing another issue. Issue is that when i stay in my local (Private) network and I try to access that web server with its public IP address, I am not able to access it.

 

So I checked that when I am inside to my local(private) network, then I have to access it with its private IP address which is 172.21.6.1/16 and when I am out of my network (over the Internet) then I have to access it with its public IP address.

 

So my concern is that why I am not able to access that server with its public IP address when I am inside to my network.

 

Actually we have an application for the same web server and for that we have to put public ip address in to the settings. Our headache is that we have to change IP address in the application every time. Please suggest something for this.

 

 

Regards,

Sagar Patel
