I am burdened with fixing a major problem at my place of work: We cannot get consistency from a VPN connection that we need with our State. I am slightly skilled with computers, but no where near most of you posting here. Please forgive any ignorance that I convey with my questions.
We run the Cisco VPN client Version 4.8.00.440 on a handful of machines on our network.
They are supposed to communicate with our State (NC) to establish a secure tunnel to allow our department to run a program that communicates with the State. We use the VPN so that we are able to connect to the State computer via the internet. This saves us money and is much quicker. The downside is that the State now will not help us with our connection because they say that any problems we are having is due to our method of connection (i.e. our ISP for the broadband we connect with).
Our ISP (broadband) is generally reliable - we have had some outages, but none that we can't live with. We have a backup ISP (DSL) so we are covered for any major outage, however our VPN problems exist whether we connect with broadband or DSL, leading me to believe this is the root of our problems.
I have done research to try to fix this problem, however I have not succeeeded. I am looking for ANY and ALL. I will list configuration settings when requested, because I am just not sure where to begin.
Basically, the VPN will timeout and kick the users out of the VPN. I have adjusted the peer response to the max of 480. I have tried to up the MTU to 1500. Then I read a posting that suggested that changes needed to be made of both sides of the VPN to really work.
Please post any and all suggestions. I am a novice but I am trying very hard to resolve this problem that is affecting us in a horrible way. We are a public saftey agency and we really need to get this resolved.
Thank you in advance.
