Here is a great website for reviewing ports and what they do. It's based off
of IANA but also includes what ports known malware uses.
http://www.bekkoame.ne.jp/~s_ita/port/port1-99.html
Check it out.

Quoting Lars Troen <Lars.Troen@sit.no>:
> DF,
> Port 264 is used for vpn clients (securemote/secureclient) for topology
> download.
>
> Port 1720 is not open by default. Keep in mind that tcp 1720 is also
> used for pptp connections. There could be a pptp server behind this
> port. Pptp also uses GRE (IP protocol 47).
>
> Or maybe they are using internet based IP phones? There used to be a CP
> vulnerability on this port:
> http://www.checkpoint.com/techsupport/downloads/docs/firewall1/r55/h323u
> pdate.pdf
>
> On port 264 the firewall offers a service to the clients. This service
> is however authenticated and you can't get anything from this service
> without authenticating first. Old versions of fw-1 accepted
> unauthenticated connections on this port. However, Checkpoint FW-1 can
> use other ports now for VPN clients. For example if you're using
> "visitor mode" the only port that will be open for vpn connections will
> be 443 (https). Checkpoint VPNs can also use udp 2764 and udp 500, tcp
> 1723 (l2tp), IP protocol 94 (old version) and IP protocol 50.
