underscores (

Enable NetBIOS
Broadcast over
IPSec
Select this check box if you the Zyxel Device to send NetBIOS (Network Basic Input/
Output System) packets through the IPSec SA.
NetBIOS packets are TCP or UDP packets that enable a computer to connect to and
communicate with a LAN. It may sometimes be necessary to allow NetBIOS packets to
pass through IPSec SAs in order to allow local computers to find computers on the remote
network and vice versa.
MSS Adjustment
Select
Custom Size
to set a specific number of bytes for the Maximum Segment Size (MSS)
meaning the largest amount of data in a single TCP segment or IP datagram for this VPN
connection.
Some VPN clients may not be able to use a custom MSS size if it is set too small. In that
case those VPN clients will ignore the size set here and use the minimum size that they
can use.
Select
Auto
to have the Zyxel Device automatically set the MSS for this VPN connection.
Narrowed
This is visible when you select any options in the
VPN Gateway
section except for
VPN
Tunnel Interface

If the IP range on the Zyxel Device (local policy) and the local IP range on the remote
IPSec router overlap in an IKEv2 SA, then you may select
Narrowed
to have the SA only
apply to the IP addresses in common.
Here are some examples.
