Linksys Router and Checkpoint Firewall

I have recently installed a LinkSys 4 Port Cable/DSL router at home. I have not been able to configure the router settings so I can VPN into corporate network. We are using a checkpoint firewall at work and a SecuRemote client. LinkSys firmware v. 1.38.5. SecuRemote v. 4. Anyone know what I need to do???? HELP!!!!
