Networking – vpn error occurring when trying to connect to a server

pptpvpnwireless-networking

I am running windows 7 and at my workplace I have created a PPTP dial-up connection so I can connect back to my workplace but I persistently receive a 807 error:

"The connection between your computer and the VPN server was interrupted…"

I resolved this issue by:

1) Right clicking the VPN connection. Select Properties.

2) Click Security tab. Make sure Type of VPN is set for Automatic (mine was set for PPTP)

This resolved my issue. Hopefully it will yours.

Your connection times out (LCP: timeout sending Config-Requests), which could be caused by your router not allowing PPTP connections to pass through from WAN to a host behind NAT. Check your router configuration whether PPTP pass-through is enabled and forwards to the machine you want to tunnel from.

I've finally found the holy grail:

This page says the following:

Issues With DD-WRT GRE Forwarding PPTP

A quick fix for DD-WRT not forwarding GRE PPTP packets.

Add the following commands to the startup commands (Administration->Commands):

/sbin/insmod xt_connmark
/sbin/insmod xt_mark
/sbin/insmod nf_conntrack_proto_gre
/sbin/insmod nf_conntrack_pptp
/sbin/insmod nf_nat_proto_gre
/sbin/insmod nf_nat_pptp

As a side note, I'm not sure why the Professional machine was able to connect correctly and at this point I don't really care now that I have a real solution that isn't enabling the DMZ.
