Configure OPT Port Upgrades
The SOHO 6 uses two methods to determine if the external port 
connection is down:
• The link to the nearest router
• A ping to a specified location.
The SOHO pings the default gateway or other location designated 
by the administrator. If there is no response, fail-over takes place.
When this feature  is activated, these actions automatically occur:
•  If the external port (EXT) connection fails, the optional port 
(OPT) connection is initiated and used
• If the optional port (OPT) connection fails the external port 
(EXT) connection is opened and used
• If both connections fail the SOHO 6 repeatedly tries both 
external and optional ports until a connection is made
There is no automatic return to the external port (EXT) if this port 
comes back online unless you use PPPoE to assign IP addresses. 
Once the fail-over has switched to the optional port (OPT), the 
administrator has to change the configuration back to the external 
port (EXT) when it comes back online.
If you use PPPoE, you can set an inactivity timeout, which disables 
any inactive TCP connections until traffic resumes. For information 
on setting up PPPoE, see “Configure the SOHO 6 External 
Network for PPPoE” on page 34. If your 
external port (EXT) 
connection fails, the optional port (OPT) connection is initiated and 
used. The optional port (OPT) stays connected until the TCP 
connection is not active (timeout). When traffic resumes, the 
SOHO attempts to connect with the external port (EXT) first. If this 
connection is active, the external port (EXT) becomes the active 
port again. If the external port (EXT) is still unavailable, the SOHO 
attempts to connect with the optional port (OPT).
