i'd need to understand if it is possible to use masquerading in a selective way.
i use a meg appliance to manage a domain, mydomain.com, and a subdomain, mysubdomain.mydomain.com.
Subdomain is used only for traffic in tls from and towards a particular external subdomain, exsubdomain.exdomain.com.
My need is this:
when an account on mydomain.com, for example email@example.com, sends a mail to exsubdomain.exdomain.com, outgoing mail has to be trasformed in a way that the sender is changed in firstname.lastname@example.org; when the account email@example.com sends mail to other destinations, no sender change is required. So a selective sender address rewriting from @mydomain.com to @mysubdomain.mydomain.com is required.
I tried to use classic masquerading configuration but i have seen that in this way all outgoing traffic is affected by masquerading, not only traffic towards exsubdomain.exdomain.com as required.
So i tried to use a custom protocol preset, but because my appliance is in explicit proxy mod it is not possibile to use criteria as destination mail address, destination ip address or destination host name.
What version of MEG are you using? I looked at version 7.6.3 and 7.5.4 in my test setup and both allow destination IP and destination host name as variables for address masquerading preset rules. Destination mail address isn't an option though. Both of my appliances are in explicit proxy.
Hi Ryan, i'm using 7.6.3.
I have spoken about destination mail address to mean destination criteria in general.
As you see in and in https://kc.mcafee.com/agent/index?page=content&id=KB71202 destination IP and destination host name as variables for address masquerading preset rules are present but not used when meg is in explicit proxy mode.
