Maybe the PIX is forwarding 25/tcp and 110/tcp to another server? A mail server in particular. Do you run Exchange? What are the banners when you telnet to those ports from an external machine? Mike.
-----Original Message----- From: Peter Rodger [mailto:prodger2008 () yahoo com] Sent: Tuesday, March 08, 2005 1:27 PM To: security-basics () securityfocus com Subject: Port open - help Hi, all I just use nmap to scan our Citrix servers and found out ports 25 aqnd 110 open through public addresses. I can use telnet ip 25/110 and ports are open. But, no 25/110 services are installed on the Citrix servers. I used nmap to scan the Citrix servers using internal IP and ports 25/110 are not open. We use PIX 500 as a firewall. I did not open 25/110 for the Citrix servers on the firewall. Why are 25/110 ports open and how do I solve them? Thanks for any help!
