basically, is there anyway to find out  why my ip address of 192.168.20.1 wont allow me to connect out on port 25??

From the inside, make sure that the smtp server is working:

telnet 192.168.20.1 25

if you get the standard banner, then 'quit' and attempt the same from the outside.  get the log info for that test and tell us what it says.

What do the logs say when you try to connect?  Is this smarthost behind the inside interface?  Are you testing by IP address or fully qualified domain name?
