currently i do a FortiMail Self study in a lab environment. i use a FortiMail Gateway behind a Sophos VM 9.306 Firewall.
everything is all right but, i created a DNAT Rule for the IBE Encrypted Portal Accsess. like Wan:8443 > FortimailGateway:8443
i can send encrypted Messages out and if i klick that Registretion Link on the reciped mail i get accsess to the web portal and can register myself. Like Chossing a password, Secret questions and so on.
But if after that i Enter my password to see the encrypted mail it tries to load the Webpage but no succsess.
It just loading and loading and loading all the time.
On the Sophos Firewall live log i see all the Dnats coming in without problem and nothing gets blocked.
Any Idea what could be a problem? is maybe something wrong with the Sophos firewall... but i mean it´s just DNAT.
i actualy had a strange behaivor on Sophos firewall activating DNAT for Exchange OWA. the connection was incredibly slow... like realy realy slow. i didn´t find out what was the problem. Trieng it out with a FortigateVM the OWA Connection was fast as usual.
Of course i do use correct Admin Ports. Otherwise i wouldn´t be able to Register a new IBE user.
as i said the strange thing is. He does allow me to register, and i see the window where i have to put my password to see encrypted file. but when i try to accsess it´s loading all the time. without sucsess.
Firewall show´s only dnat happening and no blocks or errors.
i will try it tomorrow with a FortiGate VM. could realy be a Sophos problem, if it´s true its realy weird.
