Windows VPNs are not so reliable (as Windows are not so reliable)
Also PC platform is not excellent network device...its better to use special network devices ... Cisco Routers has no hard drives (all is stored on flash) - so probability of crash is much more lower...
Cisco router has also much more better encrypting performace for IPsec VPNs

So its plus for Cisco routers..
What is reason for deploying Windows VPN???
I see only one case when use Windows VPN - its place syslog server on Win server and create Ipsec VPN for log messages - its good from security reasons
