I have realized there is a delay of at least 3 or 4 hours in displaying my posts here. My reply here will not show up until quite a few hours later.

The router Fios-G1100 does not have an option for PPTP.

I have verified that RRAS is running and PPTP is enabled.

In the event viewer, there are no entries for RRAS. There is only one for System:

A connection between the VPN server and the VPN client 72.74.77.135 has been established, but the VPN connection cannot be completed. The most common cause for this is that a firewall or router between the VPN server and the VPN client is not configured to allow Generic Routing Encapsulation (GRE) packets (protocol 47).

 

I tried to use an Android device with WF turned off to make a connection (type IKEv2/IPSec MSCHAPv2), but nothing happened on the server side.
