INNER MAIL: EXCHANGE 2013
MAILGATEWAY : PVM

Employees connect to the mail gateway from the Internet through the mail client through port 25, and SMTP cannot pass the authentication
 
Yes - the PMG is meant to be used by other mail-servers, and is not a proxy for your users who use SMTP-Auth

Simply let them connect directly to port 587 on the Exchange (preferably via a VPN)

I hope this helps!
