I have a lan-to-lan tunnel between two sites working well but i have an intermitent problem when we connect more than one person from one site (VPN3020) to the same server in the other site (Checkpoint). The tunnel remains ok but there is no application traffic (in an intermitent way). I saw in the VPN logs that there is a continuous renegotiation of the phase 2 just when the problem appears (in the file attached). This log is repeted the same every second. The tunnel is ok in both sides and there is no problem when is used by only one person.
I didn't find a solution. I have a Check Point firewall and I had to change my Lan to Lan tunnel fron de Cisco VPN to the firewall, where the tunnel works correctly. If you found a solution, please tell me. Thanks.
