What are vmnet1 and vmnet8? Can you ping your gateway 202.88.160.161?
those are virtual nic's set up by vmware.

You are using Hathway's cable modem, and I recollect that it uses a netmask of 255.255.254.0, since the third octal value is different for your IP and Gateway. Maybe in your area it uses the same values. However if your laptop accesses the gateway, the entries may be OK.
#auto eth1 #iface eth1 inet dhcp
#auto eth2 #iface eth2 inet dhcp
#auto ath0 #iface ath0 inet dhcp

I have added a line for essid in /etc/network/interfaces but iwconfig shows it to be off/any
I am able to ping to and from my router machine to my laptop, it's just that when I run the iptables commands that the router machine is no longer able to access the net itself.
If you want a more easy firewall setup, use Arno's firewall. It asks questions during setup and you can configure it to your choice. You can also re-configure it using sudo dpkg-reconfigure arnos..... It will automatically start on your PC startup.
If I then do a /etc/init.d/networking restart, the router machine is able to connect to the internet but the laptop is cut off.
