If you do not need access to that server from the outside, then the ports should be safe to close. Closing the ports should not affect internal access to the server.

Port 25 = mail traffic
Ports 80 and 443 = web traffic
Port 1723 = VPN traffic

As I look again at port 443 (SSL VPN) it can be used for other secure sites, so take care about closing it. You probably can, but just check the outcome. .... Thinkpads_User

If you close off port 80 it will stop web traffic. That seems to me to be unnecissarily restrictive. You probably can safely leave 443 open without big issue. I do not have issues with ports 80 or 443 at my clients (Juniper Netscreen Firewalls). .... Thinkpads_User

neil40m does have a point - 80 and 443 are safe to close if you are not running any other web sites on the server.

25 is safe to close if you do not have a e-mail server running.

987 and 1723 are safe to close if you don't host VPN.
