2.2.3 Interface to Interface (From VPN Tunnel)

This example shows the flow from a VPN tunnel though the ZyWALL, not to the
ZyWALL or to another VPN tunnel (VPN concentrator).
Ethernet -> VLAN -> Encap -> ALG -> DNAT-> Routing -> zFW -> IPSec D ->
ALG -> AC -> DNAT-> Routing -> FW -> IDP -> AP -> CF -> AV -> AS -> SNAT -
> BWM -> Encap -> VLAN -> Ethernet

2.2.4 Interface to Interface (To VPN Tunnel)

This example shows the flow to a VPN tunnel from a source other than the
ZyWALL or another VPN tunnel (VPN concentrator).
Ethernet -> VLAN -> Encap -> ALG -> DNAT-> Routing -> FW -> IDP -> AP ->
CF -> AV -> AS -> SNAT -> IPSec E -> Routing -> BWM -> Encap -> VLAN ->
