Description (partial)

When using ACL with specific IP address for ESP/UDP ( IPSEC VPN)  traffic, the packet capture utility does not capture the traffc but when we do ip any any, we see the traffic. The same traffic is seen in the show conn.

ACE 4710

Issue: When we run a packet capture utility, we don't see any traffic captured by the ACE.

--> Tried using IP host statements in the ACL.
--> Tried any any with port (udp any any eq 500)
--> The show conn shows UDP traffic connections in the sh conn stats and the lb stats increment.
--> Strangely, there is no packet/ traffic seen on the ACE captures.
--> Reload DOES NOT solve the issue.
