Cisco VPN connection problems.
 

I need to connect to my work using VPN and have tried the following:

* Using the Cisco VPN client for Linux
* Using kVPNC
* Using VMWare with a WinXP Image and the Windows Cisco Client


My work requires use of a user certificate. I had it working fine before on an older windows laptop but that got a bad virus so I need to way to just VPN in from linux.

Progress from the linux side:
-The user certificate I was given was base64 which the linux Cisco VPN client didn't like so I converted it over to DER and it imported fine. I stuck a valid connection profile under /etc/opt/cisco-vpnclient/Profiles which is in this form:

[main]
Description=
Host=myworkhost.com
AuthType=3
GroupName=
GroupPwd=
enc_GroupPwd=
EnableISPConnect=0
ISPConnectType=0
ISPConnect=
ISPPhonebook=
ISPCommand=
Username=username
SaveUserPassword=0
UserPassword=
enc_UserPassword=
NTDomain=
EnableBackup=0
BackupServer=
EnableMSLogon=1
MSLogonType=0
EnableNat=1
TunnelingMode=1
TcpTunnelingPort=443
CertStore=0
CertName=
CertPath=
CertSubjectName=cn=My Work
CertSerialHash=<certificate thumb print>
SendCertChain=0
PeerTimeout=90
EnableLocalLAN=0

When I try to connect I get this:

Initiating TCP to ***.***.***.***, port 443
Secure VPN Connection terminated locally by the Client
Reason: Failed to establish a VPN connection.
There are no new notification messages at this time.

Any ideas on this?

From the windows side

I managed to get everything installed and the certificate imported in my VMWare image (which is connected through my network using NAT) but when I try to connect I get the following error:
Secure VPN connection terminated locally by the Client.
Reason 412: The remote peer is no longer responding.

It is if the response is getting block when trying to get back through to VMWare?
Any ideas?

I have no idea whether this is at all related to your issue, and I am not exactly an expert. I had a really hard time establishing the connection to a MS-PPTP (where the VPN Server is a Cisco 3000 Series VPN Concentrator).

It turned out that I had to tune the MTU or MRU parameter in my Linux VPN settings. In my current, working setting, they are both at 1500. (I believe the default was 1418 or so.) I had a very hard time fixing this as there was almost no info in the forums.

Good luck.
