Our ISP has assigned a small (/29) block of routable IPs to our WAN. Our LAN consists of private IPs
The goal is for when our mail server makes an outbound SMTP connection, it goes out on a predictable IP address, so we can designate a PTR DNS record.
I'm assuming an 'ip nat inside source static..' statement would be what we want? Do we tie it to the SMTP protocol?
Any input/direction would be helpful. Thank you
