WAN Settings

This page can be used to configure WAN specific settings like the Maximum Segment Size (MSS).
The MSS corresponds to the largest amount of data (in bytes) that the router can handle in a single,
unfragmented TCP segment. In order to avoid any negative side effects the number of bytes in the
data segment and the headers must not add up to more than the number of bytes in the Maximum
Transmission Unit (MTU). The MTU can be configured per each interface and corresponds to the
largest packet size that can be transmitted.
