I personally suspect you don’t see it discussed as even a possible solution very often because (security implications aside) in most use cases, locking down to IPs isn’t useable for a mobile workforce. VPNs (in addition to having a high level of security) work extremely well for both mobile and home-based workers.
Have a look at Zerotier, we have been using it for some time now, and it's great! can host on some firewalls and also on Devices such as mobiles and PCs.
I think Todyl may be similar... a product I've been looking at seriously.
