The address involved is the PAT address for one subnet, so yes, it could 
well have been a conversation initiated by a host on our network, but when 
I checked the translation tables were empty.  Unfortunately, the logging is 
so verbose (for translataions) that we don't have it enabled, so we can 
only tell if a conversation is active.

In any case, it looks like my surmise about BigIP was correct.
