Hi Guys,

Just installed Windows Small Business Server 2008 Standard, with Service Pack 2.

Now trying to get Exchange Server 2007 to send external emails to my ISPs smart host.

The SBS machine has IP:192.168.1.220, I have a ADSL router at IP:192.168.1.1 and a test client running XP Pro at IP:192.168.1.89

I have temporarily disabled the Firewall in SBS 2008.

So; if I do;

telnet 80.168.45.10 25 from the XP machine I get this;
220 relay.clara.net ESMTP [relay05]

telnet 192.168.1.220 25 from the XP machine I get this;
220 FACTORYSRV.nsl.local Microsoft ESMTP MAIL Service ready at Tue, 30 Mar 2010 16:13:42 +0100

telnet 192.168.1.220 25 from the SBS machine I get this;
220 FACTORYSRV.nsl.local Microsoft ESMTP MAIL Service ready at Tue, 30 Mar 2010 16:14:53 +0100

telnet 80.168.45.10 25 from the SBS machine I get this;
Connecting To 80.168.45.10...Could not open connection to the host, on port 25: Connect failed

I even setup a SMTP server on a client PC and telneted from the SBS machine onto the client using port 25.

It appears that SBS 2008 won't let me connect using port 25 to a server on an external network, has anyone experienced this before?

Thanks.

Do you have any hardware firewall between your SBS box and the internet, or
just the ADSL router?

Did you finish configuring the SBS box using the wizards? Specifically the
CTIW?
