John (or Tom), 
 
If I can get this problem fixed and my paycheck secured,  you can be as
offensive and harsh as you may wish. 
 
When I connect the Internal adapter (192.168.1.xx) local network
directly to the router, I receive email.
 
When I connect the  External adapter (12.249.21.225) internet directly
to the router, I receive no internet mail.
 
the TZO software is online and connects as 12.249.21.225 either if I
connect the Internet cable to either internal or external adapters.
Thanks to the good Doctor, I was able to resolve setup issues with the
ISA on the TZO filters. Even TZO didn't know how to do that correctly.
The only change I make, is enabling the External adapter (12.249.21.225)
and making it the default gateway while removing the gateway address
from the Internal adapter. When I do that, I lose the ability to receive
email from TZO. And John, we use the Linksys, it forwards port 25 to
192.168.1.xx to create a DMZ with a public web server that is off the
SBS2000 server. 
 
Another strange item is that when we are in multihomed mode, we cannot
reach  or ping the Link Router. We ping it only if we are single homed
with the internal adapter using the Linksys 192.168.1.1 as the gateway.
Moreover; in either mode, the server and ws browser reach the internet.
