Microsoft I CS Mode Overview

MS I CS (Microsoft I nternet Connection Sharing) mode provides wireless AP connectivity to

SoftGate clients and I nternet Connection Sharing to an existing LAN through the SoftGate

hosts LAN adapter. When SoftGate is configured in MS I CS mode, SoftGate clients are

leased I P addresses using DHCP services from the SoftGate host. The range of I P addresses

assigned to clients in this mode are 192.168.0.0-255.

A typical scenario for configuring SoftGate in I CS mode is when the SoftGate host computer

is leased a single I P address from an I SP and multiple computers need to share a single

network connection through the I SP. The SoftGate host will provide wireless AP functionality,

DHCP service, and NAT services to SoftGate clients in such an environment.
