I have managed to get a pix 506 firewall (OS version 6.3(3))to communicate with an snmp monitor on the far side of a vpn tunnel. I would like to use snmp to monitor the state of the vpn tunnels on my pixes (even something as simple as "current state = QM_IDLE", for example) but I've been unable to find anything that would allow me to do that. The only MIBS that show up on my snmp monitor are for general system info - like contact information - and interface status. Is there a way to monitor a pix's vpn tunnels using snmp?
