Ok. I was able to get it to work.

Things to note:

• With current version of Raspbian (JESSE/LITE), the use of /etc/network/interfaces is obsolete. But keep it as it is used by if-up and if-down scripts.

My Setup

• Gave Raspberry Pi's eth0 a static IP address, connected to router's WAN port.
• Gave router a static IP address on the same network with the Raspberry Pi as the gateway.
• Installed dnsmasq [sudo apt-get dnsmasq] on the Raspberry Pi.
• Configured packet forwarding [net.ipv4.ip_forward = 1] in /etc/sysctl.conf
• Configured routing using iptables
• sudo iptables -t nat -A POSTROUTING -o usb0 -s 192.168.2.0/24 -j MASQUERADE. usb0 is the source interface. One can add a post-up script in /etc/network/interfaces to automate this.

Here's what I did:

/etc/network/interfaces

auto lo    
iface lo inet loopback 
iface eth0 inet manual    
auto wlan0 
iface wlan0 inet manual

        auto br0 
        iface br0 inet static
        address 10.1.1.13
        gateway 10.1.1.1
        netmask 255.255.255.0
        bridge-ports wlan0 eth0
        bridge-stp off
        bridge-fd 0
        bridge-waitport 0

auto usb0

The raspberry PI's eth0 is connected to the router's WAN and the latter gets its WAN IP address from the phone.

I confirmed all clients connected to the router can talk to each other and have internet connection.
