Can anyone share a working setup for a Fortigate (60C-80C) (FortiOS 4 MR2) for an SBS 2008 server.
Especially to make the firewall accept SMTP traffic (25) on both Wan Interfaces?
When using only one Wan you can use a VIP (Virtual IP) to forward all traffic on port 25 to the server but you can do this only once per port.
There is an example on Fortigates knowledge base but this assumes a seperate SMTP server in the DMZ.
Can it be done without the DMZ? Any examples?
I have made all the ISP side changes with 2x diffrently weighted MX (and corresponding A records) pointing at the correct Permanent IP addresses on Wan1 and Wan2?
Any suggestions would be appreciated.
