I have a pair of ASA5520 units at the remote end of a site to site VPN tunnel.
I have an NMS package managing/monitoring all of my devices at the remote end, including the ASA units themselves. However, although I can get access to and reports from the active unit, I get nothing from the passive unit.
On the active unit I can get SNMP, run ASDM, ping, etc from my end of the tunnel. On the passive I get none of these.
Can anyone give me any suggestions as to the cause ?
