BorderManager and Cisco….VPN service

We have a existing Cisco Pix acting as our firewall-NAT device. I want to put Bordermanager VPN service around this device. Called Cisco and Novell tech support and they both want control of the main link to the internet. #1 has anyone solved this? #2 Does anyone use Cisco PIX as thier VPN to a Novell netowrk? …… If you can help let me know….. Thanks
