Hello I am really need your help.
My current ISP is AT&T and I am changing to another ISP because I need better speed and better price.
My new ISP sent me some information, they say that I need to do some changes on my server.
My network is very simple, my sbs 2003 has an exchange server that download our emails from our Email provider (my server doesn't connect directly to the internet), I do not have VPN, so we have asigned IPs Public but we do not use them.
I am sending an attachment with my current router cabling and addressing diagram(from AT&T) and the values that I have on my server. Based on this information what are the changes that I need to do on my side(server).
The tecnician came and confused me about the IPs Public.
Thank you for your help
