Introduction
Things I have done with a WRT54GL router running ddwrt custom firmware:
- Single router with 2 subnets each with seperate vlan, IP block, DHCP server, and firewall rules.
- VLAN trunking
- QoS traffic prioritization based on IP address
- WPA encrypted wireless point to multipoint bridging
Things I may implement in the future:
- Multiple wireless networks on the same router with different SSIDs and different vlan tags
Details
Adding a third vlan and network
These steps assume you already have two other vlans configured.
Add ports to the new vlan
nvram set vlan4ports="0t 5t" nvram commit
Create a startup script to load firewall rules and configure the interface
echo '
#!/bin/ash
PATH="/sbin:/usr/sbin:/bin:/usr/bin:${PATH}"
iptables -I FORWARD -i br0 -o vlan4 -j ACCEPT
iptables -I FORWARD -i vlan4 -o br0 -j ACCEPT
iptables -I FORWARD -i vlan4 -o vlan1 -j ACCEPT
iptables -I INPUT -i vlan4 -j ACCEPT
ip addr add 10.7.1.7/24 brd + dev vlan4
ifconfig vlan4 up
' > /jffs/etc/config/vlan4.startup
chmod 750 /jffs/etc/config/vlan4.startup
