Recent enhancements to IP Security (IPsec) VPN simplify firewall policy configuration for VPN connectivity. Dynamic Multipoint VPN (DMVPN), IPsec Virtual Tunnel Interface (VTI), and site-to-site VTI allow the confinement of VPN site-to-site and client connections to a specific security zone by placing the tunnel interfaces in a specified security zone. Connections may be isolated in a VPN DMZ if connectivity must be limited by a specific policy; if VPN connectivity is implicitly trusted, VPN connectivity may be placed in the same security zone as the trusted inside network. This paper offers basic configuration guidelines for the relevant portions of IPsec VPN configuration.
