Heya Guys,

Just a quick one, we seem to have quite a few open ports on our WAN interface of our Ironport C100 (AsyncOS Version 6.0.0-746).

We did a port scan this morning and the results are:

Starting Nmap 4.20 ( ) at 2008-04-30 10:30 BST
Interesting ports on [our Ironport FQDN] ([our Ironport IP]):
Not shown: 4984 closed ports
21/tcp open ftp
23/tcp open telnet
25/tcp open smtp
80/tcp open http
110/tcp open pop3
119/tcp open nntp
139/tcp open netbios-ssn
143/tcp open imap
443/tcp open https
512/tcp open exec
513/tcp open login
514/tcp open shell
554/tcp open rtsp
993/tcp open imaps
1720/tcp open H.323/Q.931
3389/tcp open ms-term-serv
MAC Address: 00:D0:68:04:D2:6A (Iwill)

Nmap finished: 1 IP address (1 host up) scanned in 100.311 seconds

We've tried all of the ports and we're getting a connection refused message, but as I've already read shutting these ports off completely would stop quite a bit of the door knob rattling.

Any ideas?

That looks like you have scanned a windows box and not your ironport box maybe your exchange/mail server.

Ack, oops :oops:

My bad, you're right, wrong scan results in the wrong file.

I stand very well corrected, lol.
