Im having a serious problem here and need help urgently!!
Im sitting at a new customer where I have reconfigured their Small Business Server 2003.
Problem was that they have never used the Exchange email but were using a mail hotel of the ISP.
I have changed the DNS so it now points directly to the server.
I have verified that this is functioning.
The server was originally configured with two NIC, one of the NIC's pointing to the router (Zyxel Zywall5).
I have disabled this NIC and reconfigured the firewall to forward SMTP, HTTP, HTTPS to the server.
When I look at the firewall everything seems ok.
HOWEVER I can't get through to the server on SMTP from the outside.
When I try to Telnet the server on port 25 from the outside I get an error telling me that I could not get a connection.
When done from the INSIDE of the LAN Im allowed access??
I belive this to be a router issue but I cant figure out WHAT?
