I want to use TLS Encryption on my SMG Appliances . For this I want to buy a Certificate from a well know third party company however I need to generate a CSR . When you generate a CSR , you can only mention one Common Name whereas we want to generate a certificate which can support upto 7-8 Host Names ( Subject alternative Names) and be usable by 4 SMG MTAs .
How can I do this via SMG Certificate Settings GUI .
