Dears experts,
When I installed (ironport ESA C670) and customize the ports (25,53,443,80) to Cisco ESA C670 (one arm - input and output) it was work correctly for mail incoming and outgoing to exchange mail 2013.
Now I cannot open the pag (https://mail.mydomain.com) from out site , because I do not have the port 443 for exchange server!, the traffic incoming from out site by public IP address NAT to private IP address to Ironport with ports (25,53,443,80)
components:
in the last : one server for web and mail with One public IP
now separated : one server for web with public IP address
: one server for exchange mail 2013 with another public IP
: ESA C670
how can I solve it?
Best regard for all experts
