PeopleSoft app in Office 365

For the purpose of eventually making our PS Financials system accessible from outside the firewall, we've been attempting to create an Office 365 app for PeopleSoft. Has anyone had any success with this, either through O365 or in a different way?

Our issue seems to be in the web profile related to virtual addressing. A user can get to a login page using the proxy address but from there they are either sent to a default screen saying their session has expired (which has the internal address) or they get an error about trying to access a cross-origin frame (which I think means that it's trying to switch back to the internal addressing). It's as if it won't keep that external URL.

I'm hoping someone has some experience with this. Thanks

What version of Peopletools are you using?
