I have several remote sites using ASA5505 terminating on a FPR2140 ASA. All worked fine until i moved the VPN's to a new internet feed. Now all traffic, SNMP etc work ok but pings dont work so monitoring system cant show them as up.
one site is still working. they all have the same config applied at both ends. Attached is the packet trace for the working and a none working site. why does icmp not get through the encryption.
