Hey,
.1 seems to be a checkpoint firewall (264 is a checkpoint port)
I'm pretty sure that NAT rules in checkpoint can be configured to behave
like this on purpose (or by mistake)

Gr,

Subject: NAT is present?

Iīm 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 donīt 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?
