hi @ all,
i plugged together two asl boxes in order to excrypt voip traffic trough a vpn.
i configured the boxes so i can ping from int lan to the external interface of the remote fw.
made entrys for the vpn connection and entered two packet filter rules each to accept in and outgoing traffic from the remote net.
icmp forwarding activated
there are the error messages and logs of my two firewalls:
