# Back to back serial

## Question

Asked by depenz on 2015-08-05 in Serial-to-Ethernet & ConfigTool.

Hi, I have two WIZ107SR that I hope to connect back to back. I.e. I want to use a serial connection to bridge two ethernet networks together. Assuming this can be done, can anyone give me the settings for the WIZnet devices. On the remote ethernet network, there is a device with ip number 192.168.20.9 (although this can easily be changed), and I’d like to connect to it (i.e. ping it) from the local ethernet network across the wiznet/serial link. Many thanks for any help, and please feel free to ask any questions to clarify the physical configuration, or anything else.
