- Error 806: The VPN
connection between your computer and the VPN server could not be
completed. The most common cause for this failure is that at
least one Internet device (for example, a firewall or a router)
between your computer and the VPN server is not configured to
allow Generic Routing Encapsulation (GRE) protocol packets. If
the problem persists, contact your network administrator or
Internet Service Provider.
- How to fix?
Cause: PPTP uses GRE (Generic Route Encapsulation) protocol to
encapsulate the VPN payload in a secure manner.This error
generally comes when some firewall in path between client and
server blocks GRE Protocol (i.e. IP protocol number 47).
Try following to resolve this error:
Allow both outgoing and incoming Protocol 47 (GRE) on any in
between firewalls. If that is not possible, deploy SSTP based
VPN tunnel on both VPN server and VPN client – that allows VPN
connection across firewalls, web proxies and NAT.
