Port scan usually means attempting a tcp connect to each 'port' on the firewall.
It is also often over a range of IP addresses.
As portscan tools go, I find nmap most useful (http://www.insecure.org/nmap)
but watch out, because portscans can crash a firewall. (Yes, I've done it, scan
out, connection table overflows, and 'boom')

These may be the listed services, but that's largely irrelevant to the firewall.
At a guess these will be some firewall control services since I know a number in
the 250+ range are used.
