1. John I appreciate your concern but it is a VERY temporary solution
for the moment, I do plan on getting a reliable firewall for all
locations but you also have to realize that some of these sites are on a
limited budget and sometimes you have to do what you can, and kinda
"McGuyver" it.  Besides the Linksys has a "builtin" firewall.  Anyways
aside from the secuirty issues what could possibly be prohibitong yahoo
email from arriving to these clients?

Oh brother. You do not know what you are doing, do you?

 

1. If you are using the included Internet Connection Firewall that comes
with Windows XP and Windows 2003 server, you do not understand. You CAN
NOT USE THAT! That is a basic basic basic dumb firewall that is only a
stop gap measure.

2. Generally speaking, (unless you purchased the cheap version,) ISA
2000 is included with Small Buisness Server 2003.

3. You are using a Linksys (what, DSL,) basic router that is not a
firewall. 

 

Some one needs to take some time and think about security.

 

Operating an Exchange e-mail server, or any flavor of e-mail server on
the Internet, REQUIRES dedication and understanding of the ramifications
of doing so. This includes taking basic standard security steps at the
very least.

 

For the Exchange server on SBS, disable the ICF and configure ISA server
and publish the Exchange server properly.

On the other client behind the Linksys, 86 the Linksys router, break
down and get a SonicWall TZ170 and configure the SMTP and POP3
protocols.

One is Win2k3 small biz srvr (Not ISA) built in firewall and the other
client has a basic linksys setup.
