VPN Concentrator 3020 - Problem with LAN-to-LAN tunnel
I'm trying to build a LAN-to-LAN tunnel using my Cisco VPN Concentrator 3020 and another piece of hardware (used the free Linux distribution IPCop and an Instagate). I can get the tunnel be build, but then the tunnel is being disconnected and I can't get a clue what is going wrong. I hope somebody here can help me a little bit.
I will take the IPCop (which should work before 1 feb this year) as example.
am using the following settings:
IKE Proposal IKE-3DES-MD5
IKE Encryption: 3DES
IKE Integrity: MD5
IKE Grouptype: MODP-1024
ESP Encryption: 3DES
ESP Integrity: MD5
ESP Grouptype: MODP-1024
This is what the Concentrator gives in his log files:
