Is it possible to configure unencrypted PPTP on the Cisco 891?

Question

VPN

This router is available, an external static IP is registered and everything works, now the provider is forcibly transferring from static to pptp and the person who set up cisco says that it is impossible to do this on this model. Is it really? Itself when with cisco had no business, I will be glad to any material on a subject.

Answer 1

Cisco 881, IOS 15.1(4)M4. PPTP is configured according to the instructions from cisco.com via vdpn and the Dialer interface
