I am not getting VPN reports for Cisco firewall's?
We can setup two kind of VPN's in Cisco firewall's as below.
- Remote Host VPN:
This is between a User PC and the Cisco firewall's. User PC could be anywhere in the Internet. There are various technologies used to accomplish the same. Firewall Analyzer supports the following types.
- IpSec:
Firewall Analyzer supports IpSec remote host vpn in Cisco firewall's. Following are the sample logs generated:

<134>Oct 20 2005 20:58:01: %PIX-6-603105: PPTP Tunnel deleted, tunnel_id = 26, remote_peer_ip = xxx.xxx.xxx.xxx
- Site-To-Site VPN:
This vpn connection will be established between firewall to firewall. In most of the cases, this connection would have been established before the Firewall Analyzer installation. Also Cisco firewall's do no hint about the traffic that is going through this Site To Site VPN tunnel in the logs. In the Firewall Analyzer VPN Reports, there is no support for VPN connection types. However, in the Traffic Reports, you can filter the report using the IP Adresses assigned to the VPN connections to get the VPN traffic reports.
