Hi everyone;
The goal of this thread is to provide a simple straight forward guide to setting up a VLAN on a WNDR3300. I have dug through the post that would seem to lay everything out however I still have some conflicting info. I will do my best to lay this out so anyone can understand what the commands are and simply what you need to enter. I will combine everything into a single post. Credit will be given to all who help. In advance a big thank you to all who can help sort this out.

Router: Netgear WNDR3300
Build: 17201 - mini
Goal: VLAN1 = Ports 1,2,3 and WiFi - DHCP enabled + access to WAN only
VLAN2 = Port 4 - DHCP enabled + access to WAN only

Please keep in mind I have not tried this yet as I don't know have to remove these settings. Likewise I have two different firewall settings and I am not sure which is correct. Also I have no access to a VLAN GUI page.

1. Telnet into the router - run these commands

2. Setup VLAN2
Code:
nvram set vlan0ports="3 2 1 5*"
nvram set vlan2hwname=et0
nvram set vlan2ports="0 5"


3. Assign IP to VLAN2
Code:
[url]nvram set ifconfig vlan2 192.168.0.1 netmask 255.255.255.0
nvram set ifconfig vlan2 up[/url]


4. Setup firewall so VLAN1 and VLAN2 can access the internet yet are separate
NOTE: I have two configurations between the two listed references and I am not sure which to use. I need clarification on this.

Code:
nvram set rc_firewall="

iptables -I INPUT -i vlan2 -j ACCEPT
iptables -I FORWARD -i vlan2 -o vlan1 -m state --state NEW -j ACCEPT
iptables -I FORWARD -i vlan2 -o ppp0 -m state --state NEW -j ACCEPT
iptables -I FORWARD -i br0 -o vlan2 -j logdrop
"

OR
Code:
nvram set rc_firewall="

iptables -t nat -I PREROUTING -i vlan2 -d 192.168.1.0/24 -j DROP
iptables -t nat -I PREROUTING -i br0 -d 192.168.0.0/24 -j DROP
iptables -I FORWARD -i ppp0 -o vlan2 -j ACCEPT
iptables -I FORWARD -i vlan2 -o ppp0 -j ACCEPT
"


5. Enable DHCP on VLAN2 - NOTE Conflicting info again; please clarify
a. In the Setup>Networking page, in the Ports section, select "Unbridged" for VLAN2 and supply the following settings: IP Address - 192.168.0.1, Subnet Mask - 255.255.255.0.
b. In the Setup>Networking page, in the DHCPD section, under Multiple DHCP Server, click Add and select "VLAN2" as the interface. (Once the page refreshes, it should also show the IP address of the interface. i.e. - "Interface vlan2: IP 192.168.0.1/255.255.255.0"

OR

a. Services Tab
DNSMasq->Enable
Local DNS->Enable
Additional DNS Options: interface=vlan2
dhcp-range=192.168.0.100,192.168.0.149,1440m
