Hi,
I have done a static from dmz to outside on my firewall and I have created an access-list on the interface outside where I permit only incoming traffic to the host through the port 443.
I have done a portscan and it seems that ports 25 and 110 TCP and some udp ports are opened. If I do telnet on the tcp ports there is a connection, but on the server there are no services for that ports.
How I can hidden the TCP and UDP ports from the portscan? Why the outside acl is bypassed? I have a PIX 515 IOS 6.3.
Thanks in advance fro your help
