I have been trying to setup a PPTP VPN with the Cisco RV215w router and have discovered that CISCO won't permit a 192.168.1.x network when a PPTP VPN is setup. I am well aware that I can't have an identical subnet at the other end, and have made accommodations for that. The copy machine people have installed some equipment and I don't have access to those machines to change the subnet on them. Hopefully there is a work around for this!
Are you on the latest firmware (1.2.0.15)? If not, you are most likely running into bug (CSCuh20473).
This bug does not allow you to add a zero to the local subnet.
I hope this helps.
Regards,
Chris
