It is possible to use an alternative DMZ server for individual AS2, X.400, HTTP(S) and all subtypes of FTP channels.
Preparing a partner channel
Create the central additional ID "ALTERNATIVE_DMZ" (if it does not already exist). NOTE A description can be found in section Additional IDs (central).
Open the channel you want to use with a dynamically assigned DMZ server and click on Additional IDs.
Create an entry "ALTERNATIVE_DMZ" and enter the IP or the URL as value. NOTE You can also use a constant %DMZ%, for example. That way you do not have to adjust all channels if the IP changes.
Sending via DMZ
If a used channel (this also applies to corresponding channels in the module "Asynchronous Sending Module (ASM)") has an additional ID ALTERNATIVE_DMZ, the alternative DMZ server stored there is used instead of the normal DMZ server at runtime. Of course, the option "Via DMZ" has to be available and set in the respective Response of the profile (or the ASM entry).
You should see the following entry in your log.
... Using new DMZ address 'vm-mac.local' for AS2 channel ...
