PPTP troubles


New Member
I've been trying to get pptpd to work correctly on one of your OpenVZ vps, but I keep getting suck with the following error:

GRE: read(fd=6,buffer=8058640,len=8196) from PTY failed: status = -1 error = Input/output error, usually caused by unexpected termination of pppd, check option syntax and pppd logs

The PPP module has been enabled and GRE is forwarded in iptables, I've gone through all the things I thought could stop it from working but no luck.

I've read that a extra module is possibly required for iptables that specifically allows GRE and PPTP protocols but I couldn't find much info on it, does it exist?

Anyone know what I'm doing wrong? Is PPTP on OpenVZ possible?

The easiest way to resolve this is to use KVM virtualization instead of openvz containers.
