Dual-WAN for DD-WRT

Releases

Pre-Releases

DISCLAIMER

  • This is in no way fully-tested

  • Some or all of this repo will need to be modified dependent on your router's hardware

  • Use at your own risk

  • DD-WRT's base WAN currently must be disabled

  • You may give up some GUI features using this script; but everything can be implemented just with terminal commands and well placed, well named scripts

  • UPNP hasn't been tested, but likely will not work

    • This is more of a feature than a problem since UPNP shouldn't be trusted anyways

Testing

Hardware

  • Netgear R7000P

Software

  • DD-WRT v3.0-r51679

Methodology

  • This repo is a modified version of a DD-WRT Wiki Article

  • Some differences are:

    • This repo moves away from the net-tools dependency

    • Vlans should be setup using swconfig (which has a GUI in newer builds)

    • wan* aliases are treated as hotswappable rather than binding to a vlan

    • lowered numbered wan (i.e. wan0) have priority over higher numbered wan and therefore all wan must have a priority number

      • That being said the current configuration sets aside your lan's *.64/27 block of addresses as being higher numbered wan priority

      • The config assumes a lan subnet 255.255.255.0 and as such only reserves the following subnets besides the aforementioned:

        • *.0/26

        • *.96/27

        • *.128/25

    • an ntpclient ip address must be set, no domains

    • dns cannot be pulled from ISP, must be set statically in nvram

    • do not use any nvram variables reserved for dd-wrt's base wan, this may inadvertently enable the base wan which will mess up the routing tables

      • except for wan_dns a space separated list of dns servers

    • this repo is preconfigured for dual-wan on interfaces vlan2 & vlan3

      • both those interfaces unbridged, and support Masquerade / NAT

    • this repo assumes connmark is enabled in your device's kernel/iptables and does not load any kernel modules for this purpose

Confirmed Working GUI Features

  • Port Forwarding
  • Port Range Forwarding
  • Everything else except obviously anything pertaining to WAN
  • Also, UPNP probably won't work (not fully tested)
  • DMZ may work given some edits to the firewall script
  • DD-WRT base firewall probably is dead when using this, rely on the firewall script

This is probably an incomplete list
