scanport utilities show port 25 open.

Hi, everybody.


My problem is that when I made a scanport no matter what app I used, always show me the port 25 open.


All traffic through the port 25 is filtered by the EWS.


I know is sound crazy, so, I show you a example:


If I made a scan port to the google DNS server ( that have only the port 53 open, show me the port 25 open:


Dunkelheit:/home/esvom # nmap


Starting Nmap 6.01 ( ) at 2013-04-18 13:01 CST

Nmap scan report for (

Host is up (0.051s latency).

Not shown: 998 filtered ports


25/tcp open  smtp

53/tcp open  domain


Nmap done: 1 IP address (1 host up) scanned in 7.88 seconds


If I take the source IP and I make an exception so that does not pass through the EWS, show me the correct information, only the 53 port open.


The EWS is in Transparten Bridge mode.


Any suggestion will be appreciable.
