I've recently replaced an 1801 with an ISR4331. I previously had a PPTP VPN set up for occasional remote access to a server inside the network while not at the site from laptops or mobile phones. I have copied the config across to the new router and while the VPN will establish I'm unable to send any traffic across it.
! Default L2TP VPDN group
! Default PPTP VPDN group
ip address 10.0.2.129 255.255.255.255
ip local pool VPN-POOL 10.0.2.130 10.0.2.142
ip unnumbered Loopback4
zone-member security inside
peer default ip address pool VPN-POOL
ppp encrypt mppe auto required
ppp authentication chap ms-chap-v2 VPN-Auth
After some searching I can see suggestions that PPTP is not supported on the ISR 4K, I am also getting the following error during set-up.
%FMANRP_ESS-4-FULLVAI: Session creation failed due to Full Virtual-Access Interfaces not being supported. Check that all applied Virtual-Template and RADIUS features support Virtual-Access sub-interfaces.
I am not really looking for a super secure/complex solution involving 3rd party applications, have I missed something obvious or do I need to look for an alternative?
After some time away from this issue I managed to get the appx trial sorted out however I'm still not able to get traffic across a VPN.
If mppe encryption is enabled the router logs an error saying full virtual-interfaces are not supported. If I remove that the session comes up and I can see traffic passing (via an ACL) however it doesn't seem to reach the client device.
