Hi,

I didn't go through the configuration (I will check) but it seems some communication issue with between server and router.

Hello,

I would agree with Deepak. Try and configure 'no keepalive' under the virtual template:

interface Virtual-Template1
description **PPTP_TUNNEL**
ip unnumbered GigabitEthernet0/0
ip mtu 1400
ip tcp adjust-mss 1360
load-interval 30
peer default ip address pool PPTP

no keepalive
ppp mtu adaptive
ppp encrypt mppe auto stateful
ppp authentication pap ms-chap-v2 ms-chap
