Scan to email issue with gmail

Hi all,

I'm a new one on Xerox forum  from Xerox Morrocco, and i need your help about scan to email using gmail server on new xerox mfds.

before on XWC7220 the scan to email works correctly using gmail smtp but after th customer has set a static IP to use a VPN on his office.

and the MFD can't send the email.

My question : is there any relation between th static IP and gmail smtp to fix this problem  ??
