    What happens if you disable 'Detect HTTP loopback' on the 'Misc' tab of 'Filtering Options'?

    2015:03:22-22:01:31 DVicSophosUTM01-1 httpproxy[10600]: id="0003" severity="info" sys="SecureWeb" sub="http" request="0xd0d30800" function="p0f_read_response" file="p0f-client.c" line="162" message="p0f: no matching host"
