I just configured the first interface of my C150 ESA with ip address, default gateway,listener, RAT and SMTP routes. I want my IronPort to handle mail for another domain with a totally independant netwotk (subnet and mail servers...). Can I configure the second interface the same way I configured the first one (obviously with all the good settings...;-)) ? Does it work? Is there no problem of IP or SMTP routing ?
To be short, I want to do two "one interface configuration" scheme with my ESA (which has two physical interfaces) and not a "two interfaces configuration" scheme
