Model: ER605 (TL-R605)  
Hardware Version: V2
Firmware Version: 2.0.1

Hi, 

Hi,

I have an Airtel fiber connection with a static IP. The LAN configuration in that airtel router is DHCP with IP series as 192.168.7.x .

 

In the ER605, I have setup the WAN as static IP with the configuration as 192.168.7.2 . 

 

The LAN configuration in router is 192.168.25.x . All the devices connected to router work fine - LAN / WAN. 

 

Now, I need to access one of my servers using the public IP.

 

For that I have referred to your article and configured it as below.

https://www.tp-link.com/in/support/faq/2153/

 

Interface: WAN

Original IP: 192.168.25.53

Translated IP: 122.x.x.120

DMZ Forwarding: Enabled

 

Now, I can access my server (192.168.25.53) using the public IP. 

However, if I login to my server, I am unable to use the internet on that server. 

 

 

Any help would be appreciated

Can you describe your network layout simply? Is there double NAT in your network? 

Can you ping through the 8.8.8.8 from server side?

Just striving to develop myself while helping others.

  @Virgo 

Hi,

Here it is:

 

I am not able to ping 8.8.8.8 from 192.168.25.25. However, if I disable 1:1 NAT on ER605, internet works on 192.168.25.25 .

 

Please let me know in case you need any other information that could be useful.

Can you enable DMZ on the Airtel gateway for testing?

  @Virgo Hi,

I did.

I tried setting it to 192.168.7.2 and 192.168.25.25 as well. Didn't work.
