Hi, I am new to this.

I have a PLC (Programmable Logic Controler) and a computer that I want to reach through a NAT one-to-one.

It seem to work but I cannot ping anything on the LAN side and the computer on the LAN cannot access Internet

The WAN1 is static at 10.114.13.65 with a mask 255.255.255.0 and the gateway is 10.114.13.1
The LAN is 192.168.0.1 with a mask 255.255.255.0

The PLC is 192.168.0.10
The computer is 192.168.0.11

The gateway for both of the equipement is 192.168.0.1


The NAT is like this :

Original IP :

- 192.168.0.10
- 192.168.0.11

Translated IP :

- 10.114.13.70
- 10.114.13.71

Interface :

- WAN1
- WAN1

Description :

- PLC
- PC

From the Maintenance/Diagnostics menu of the TL-ER6120 I can ping the PLC and the PC on the LAN and I can ping web sites from the WAN1

From the network 10.114.13.xxx I can ping the router 10.114.13.65 but I cannot ping the PLC or the PC at 10.114.13.70 and 71.

Does someone can help me to be able to access internet with the PC and also, is ther a way that I can ping the LAN side from the outside ?

Thank-You

>>>is ther a way that I can ping the LAN side from the outside ?You cannot ping LAN side from outside. It's still NAT relationship between 192.168.0.10 and 10.114.13.70.

Thanks' for the answer. My concern was that I wasn't able to ping th 10.114.13.70. But I manage to resolve my problems. I just had to put the right DNS in the client. After that, everything seems to work, I have acces to the Internet and the client is now "pingable".
