And i cant seem to get remote desktop working through the Ethernet 0/1 port. I will attach a network diagram with basic information. It any one needs more info I will suply it. PLZ Help.
Firstly the email. It could be a NAT problem between your local server IP and an external public IP address, so you may need to look into this. It could also be that you don't have reverse DNS setup so that your NAT'ed IP address doesn't resolve to a hostname. Some ISPs will not allow you to send email unless your IP resolves to a hostname.
Another common problem could be that you are using the wrong ISP SMTP mail server to send email. This is only applicaible if you are using your ISP's mail server as a relay rather than sending out email directly.
Your RDP issue sounds very much like a NAT config problem.
The following documentation should be able to provide you with a walkthrough on how to sort this out.
To summarise, check your NAT configs for both email and RDP problem. Ensure that your SMTP mail servers NAT'ed IP (Internet facing IP) resloves to a hostname and lastly if you are using your IOSP as a mail relay to send email confirm you are using the correct SMTP mail server name.
