Steve,
I have added that port. Maybe is enough. Please try this. You need to update
nDPI then recompile ntopng
Cheers Luca

Hi Luca,
Is there some reason this can't be identified from the fact it is UDP to well
know port 4500?
The whole ipsec nat-t specification is defined in an RFC.
http://tools.ietf.org/html/rfc3947
I can get a tcpdump but I don't control the endpoints so it will difficult to
get the
initiation part, would that help?

all protocols in nDPI should be reliable with the exception of Skype and
Bittorrent that have some heuristic as you can see. Please provide me a trace
(full packet size) in pcap format and I will debug this problem

Hi Luca,
nDPI is mis- identifying ipsec nat-t traffic as skype - port 4500 is the
default port for ipsec nat-t.
