Port scan show a lot of open ports
-
Bit of an urgent one. I’ve only just set up my SSG5 so I’m monitoring a few things. I’m alarmed to see that when I do a port scan there are loads of open ports. I expected to see only the ports open based on the policy (25, 443, etc) instead I see 1, 2, 3, 4, 5, 6, 7.
How do I close them?

Thanks, this was indeed a bad port scanner. I ended up going to Shields Up to test the firewall and it was fine.

Sounds like something is misconfigured, or whatever you are using for a portscanner is generating false information. Try scanning with nmap:
nmap -sT -n -p 0-65535 <ip address="">If it has the same results, post your config.</ip>
