Negotiation timed out - issue with windows IKE2 VPN

  • 772

This is a complete new one for me.

We've got a VPN (cert based) running happily on the domain. However after a while of working ok (and usually after I get to home to the other side of town) I find I cannot connect to the VPN anymore.

The following error occurred in the Point to Point Protocol module on port: VPN1-125, UserName: . Negotiation timed out.

Obvioulsy I've googled a bit but I cannot seem to understand what to do. Has anyone come across this issue and resolved it please?

I'm not a sysadmin (we are a three man company) but it's only me it seems to happen to. The other two use windows 7 professsional as client while I use windows 7 ultimate. All the machines are on the domain.

  1. Have you completely blocked ICMP on your home firewall? Has your home ISP blocked all ICMP traffic?

    See What might prevent IKE handshake success in building an IPSEC tunnel?

    It is mostly about Cisco VPN, but the same things will affect any IPSEC VPN.
