Re: Adding a Linksys Wireless ROuter to Network

["Jones, John (US)" <John.Jones@xxxxxxxxxx>]

Since you're not really using it as a router, do not use the "internet"
port.  Just connect the WAN cable to any of the bundled switch ports on
the unit.  Also, when you're in the WRT's config blocking port 25, be
sure to use some version of WPA for wireless security.  At this point
you're really using it as a Wireless Access Point (WAP) with a switch
rather than as a full-fledged router/internet gateway.  

As the WRT has little in real management capabilities and it's really a
consumer-oriented product I would have recommended a small switch + a
real WAP.  There are Cisco products that would integrate with your
others and allow remote management etc.  Or, for an all-in-one,
something like http://www.securecomputing.com/index.cfm?skey=1558 .
It's feature-overkill but it isn't that expensive and is designed for
commercial environments.  And it has an access point mode.
