Got an ACE 4710 with a basic config that seems to work for all traffic except large downloads.
I've attached the current config
As I mentioned I can do normal HTTP to a standard destination like google or SSH through the ACE or ICMP
If i try to get a large file from the server side of ACE, then a trace shows that the first and subsequent 1460Byte packets dont go through ACE
I've thought of parse lengths, but i cannot see any that seem to affect the generic L4 maps that I am trying to use
