Characteristics

• 3

-party firewall provides NAT, Firewall and DHCP to PCs

• WAN interface has one free IP address:

− The EdgeMarc is assigned one IP address from the WAN subnet

− Other address(es), including the one already being used by the 3

-party

Firewall/VPN device, are bridged through the EdgeMarc to its LAN interface.

• EdgeMarc LAN interface uses two VLANs

− VLAN #2730 with private subnet for phones (associated with EM LAN port 4).

This LAN uses standard 802.1 frames.

− VLAN #2 with a public subnet for the 3

-party VPN / Firewall device (associated

with EM LAN port 3). This LAN uses standard 802.1 frames.

Limitations

• This configuration requires two drops per cube or office.

− DHCP is used separately for PCs and Phones, requiring two broadcast domains.

Two broadcast domains means two LANs.

• This configuration is only possible on Edgewater appliances that provide VLAN

support (200/250/4300/4500/4600 Series EdgeMarcs).
