DGFV338 Primary LAN The Primary LAN settings can be defined on the GUI of the DGFV338 (Network Configuration, LAN Setup). If DHCP is required ensure that the correct Starting IP address and Ending IP address are configured including the DNSs settings. - Netgear GS748TS | Shared access to the Internet for multiple VLANs - No routing - Page 5
LAN to the DGFV338 the Multi-homing option should be used. This can be accessed via the GUI (Network configuration, LAN Setup, Multi-Homing) PCs with an IP address within this range will need the IP address, Default Gateway and DNS servers (if different from the Default Gateway) manually set. - Netgear GS748TS | Shared access to the Internet for multiple VLANs - No routing - Page 6
are created on the Smartswitch via the GUI (Switching, VLAN, Basic, VLAN configuration). To complete the scenarion 3 VLAN will need to be created. The two pictures below show the creation of VLAN20, and the results of the creation of all the VLAN required to complete the scenario (VLAN20, 30, 40) - Netgear GS748TS | Shared access to the Internet for multiple VLANs - No routing - Page 7
can be assigned via the GUI (Switching, VLAN, Advanced , VLAN membership). Three options are available: - No membership (no simbol appearing in the gray box underneath the port number) - Untagged membership (U) - Tagged membership (T) In order to - Netgear GS748TS | Shared access to the Internet for multiple VLANs - No routing - Page 8
, Port PVID configuration). It is important that the PVID matches the VLAN a port is member of, unless such port belongs to multiple VLANs (in which case the PVID must still be set and be unique, but can match any of the VLAN IDs). In our scenario the following PVID will apply: Ports 0/5 - 0/6 (PVID - Netgear GS748TS | Shared access to the Internet for multiple VLANs - No routing - Page 9

GS700TS FS700TS – Access to the Internet on multiple VLANS using Multi-
Homing
This document describes how to obtain Internet access on multiple VLANs using one Internet
gateway capable of managing multiple IP subnets (Multi-homing).
The procedure described can apply to all the Smart Switches and VPN Firewall with new Web
Interface (defined as the one with the Menus appearing horizontally on top).
