That is very likely a transparent proxy/cache showing that behavior. All HTTP/S traffic, irrespective of the 
destination is being redirected to a cache server. 

Try a HTTP echo command and see if you get output. It may reveal the make of the appliance or cache software.

Subject: NAT is present?

I´m pen-testing a subnet, and when i scan the open ports i get something
similar to this:

*.*.*.1

PORT    STATE SERVICE
80/tcp  open  http
264/tcp open  bgmp
500/tcp open  isakmp


*.*.*.2
PORT STATE SERVICE

80/tcp  open  http
              https
*.*.*.3

PORT    STATE SERVICE
80/tcp  open  http
              https

All the host of the subnet seems to have http and https open but when i
try to connect to it a lot of then don´t back a response.
I thing that the .1 (seems to be a router) have NAT and open http and
https por all the hosts (up or down) .
Can someone help me?
