You can configure a tunnel interface to support Generic Routing Encapsulation version
1 (GREv1) encapsulation. When enabled, the interface encapsulates IP packets in the
tunnel in IPv4 packets using GREv1. You must specify the key parameter to append the
value to outgoing packets (incoming packets must have this value too).
You can use GRE to forward multicast packets through non-multicast aware routers and
devices.

You can configure the following address translation methods on the security device:
MIPs
VIPs
Mapping services and ports
DIPs
Port Address Translation
DIP with extended Interface
Incoming DIP for SIP traffic

A mapped IP (MIP) is a direct one-to-one mapping of one IP address to another. The
security device forwards incoming traffic destined for a MIP to the host with the address
to which the MIP points. A MIP is a static destination address translation that maps the
destination IP address in an IP packet header to another static IP address, enabling
inbound traffic to reach private addresses in a zone whose interface is in NAT mode.
When a MIP host initiates outbound traffic, the security device translates the source IP
