Setting up PCAnywhere to work

I need to communicate with someone who can help me set up PC Anywhere to work across the Internet and connect with my box behind a firewall. I am using a Raptor Firewall and would like to set up PC Anywhere to communicate with my mahcine when I am not at work. I am the only person in the IT department and it’s critical to be able to do this. My version of Raptor doesn’t have VPN capabilities and they don’t want me to upgrade it. Can anyone help? Email me at Esemposki@diamondsystem.com if you can. Thanks in advance!
