OT: Selective routing and proxying

[Aryeh Friedman]

My significant other's employer (a public university) has payed for
subscriptions on many newspapers and other periodicals that normally are
pay-walled and allows anyone on the campus network (or VPN to it) us said
subscriptions if you use the library's proxy server.   There are other on
campus only services that they want to also access like virtual desktops
and network drives.  For privacy reasons we want to make so only access to
the said subscription and/or on campus IT services are routed via the VPN
connection/library proxy and all others go out our normal ISP.  Note we
also have and other VPN connection to one of my clients that due to privacy
regulations (HIPAA) must be used for all our work with them.

What is the best way to handle all this?  (Currently have 2 physical
FreeBSD machines in the house and 2 more running as VM's and one Windows VM
and one Windows physical machine... the VM's use bhyve)
