Description

Idle timeout

By default, the SnapGear appliance dials-on-demand (i.e.

 

when there is traffic trying to reach the Internet) and

 

disconnects if the connection is inactive (i.e. when there is

 

no traffic to/from the Internet) for 15 minutes. If using dial-

 

on-demand, this value can be set from 0 to 99 minutes.

 

Selecting Stay Connected will disable the idle timeout.

Redial setup

If the dial up connection to the Internet fails, Max

 

Connection Attempts specifies the number of redial

 

attempts to make before discontinuing . Time Between

 

Redials specifies the number of seconds to wait between

 

redial attempts.

Statically assigned IP

The majority of ISPs dynamically assign an IP address to

address

your connection when you dial-in. However some ISPs use

 

pre-assigned static addresses. If your ISP has given you a

 

static IP address, enter it in Local IP Address and enter the

 

address of the ISP gateway in Remote IP Address.
