Dialup security and firewalls

Hi

I have a windows 2000 network where all communication passes through a hardware firewall.

I want to install a modem on one of the servers in order to be able to send sms messages from a package I have installed. Obviously this enables anotehr entry point into the network as the modem will have to dial up and it cant dialup through the firewall. What is the best way of securing the server?

Thanks

Greetings, arunuk!
  You can use a software firewall like ZoneAlarm. I use it with my dialup modem, and it blocks the probes into my computer.

Thought as much, I guess that incombination with allowing dialout only should be adequate
