Script to turn a WRT54GL into a 5-port switch

#!/bin/sh
# Script: Turn a default WRT54GL (with openwrt) wap into a 5-port router.
# Author: Jason Miller
# Status: Not done yet. Routing needs to be added.
# End Configuration:
# WAN PORT: 10.0.0.23
# Port 1: 192.168.1.1
# Port 2: 192.168.2.1
# Port 3: 192.168.3.1
# Port 4: 192.168.4.1
# NOTES:
# - It is a VERY good idea to disable the IPTables init script first.


# It's good to have stuff written to non-volatile files in the event that something
# gets dorked up and you need to reboot to see what happened.

ERROR=/etc/out.err # For error messages

# For whatever reason, the port labels on the WRT case
# do not match the internal IDs of each port in the switch.
# We are also doing VLANs 11-15 instead of 1-5 because I
# really didn't want to take the extra time to debug
# the use of VLAN 1 (which is reserved by the default
# configuration).
