# Nodogsplash Configuration File
#
# Parameter: GatewayInterface
# Default: NONE
#
# GatewayInterface is not autodetected, has no default, and must be set here.
# Set GatewayInterface to the interface on your router
# that is to be managed by Nodogsplash.
# Typically br0 for the wired and wireless lan on OpenWrt White Russian.
# May be br-lan on OpenWrt Kamikaze.

GatewayInterface wlan0
# FirewallRuleSet: authenticated-users
#
# Control access for users after authentication.
# These rules are inserted at the beginning of the
# FORWARD chain of the router's filter table, and
# apply to packets that have come in to the router
# over the GatewayInterface from MAC addresses that
# have authenticated with Nodogsplash, and that are
# destined to be routed through the router. The rules are
# considered in order, and the first rule that matches
# a packet applies to it.
# If there are any rules in this ruleset, an authenticated
# packet that does not match any rule is rejected.
# N.B.: This ruleset is completely independent of
# the preauthenticated-users ruleset.

FirewallRuleSet authenticated-users {
# You may want to open access to a machine on a local
# subnet that is otherwise blocked (for example, to
# serve a redirect page; see RedirectURL). If so,
# allow that explicitly here, e.g:
# FirewallRule allow tcp port 80 to 192.168.254.254
# Your router may have several interfaces, and you
# probably want to keep them private from the GatewayInterface.
# If so, you should block the entire subnets on those interfaces, e.g.:
#FirewallRule block to 192.168.0.0/16
#FirewallRule block to 10.0.0.0/8
# Typical ports you will probably want to open up include
# 53 udp and tcp for DNS,
# 80 for http,
# 443 for https,
# 22 for ssh:
#FirewallRule allow tcp port 53
#FirewallRule allow udp port 53
#FirewallRule allow tcp port 80
#FirewallRule allow tcp port 443
#FirewallRule allow tcp port 22

# These rules apply to packets that have come in to the

# are not on the BlockedMACList or TrustedMACList,
# are *not* authenticated with Nodogsplash. The rules are
# considered in order, and the first rule that matches

# any port 80 request to this remote host.
# Note that the remote host's numerical IP address must be known
# and used here.

# EmptyRuleSetPolicy directives
# The FirewallRuleSets that NoDogSplash permits are:
#
# authenticated-users
# preauthenticated-users
# users-to-router
# trusted-users
# trusted-users-to-router
#
# For each of these, an EmptyRuleSetPolicy can be specified.
# An EmptyRuleSet policy applies to a FirewallRuleSet if the
# FirewallRuleSet is missing from this configuration file,
# or if it exists but contains no FirewallRules.
#
# The possible values of an EmptyRuleSetPolicy are:
# allow -- packets are accepted
# block -- packets are rejected
# passthrough -- packets are passed through to pre-existing firewall rules
#
# Default EmptyRuleSetPolicies are set as follows:
# EmptyRuleSetPolicy authenticated-users passthrough
# EmptyRuleSetPolicy preauthenticated-users block
# EmptyRuleSetPolicy users-to-router block
# EmptyRuleSetPolicy trusted-users allow
# EmptyRuleSetPolicy trusted-users-to-router allow
# Parameter: GatewayName
# Default: NoDogSplash
#
# Set GatewayName to the name of your gateway. This value
# will be available as variable $gatewayname in the splash page source
# and in status output from ndsctl, but otherwise doesn't matter.
# If none is supplied, the value "NoDogSplash" is used.
#
# GatewayName NoDogSplash
# Parameter: GatewayAddress
# Default: Discovered from GatewayInterface
#
# This should be autodetected on an OpenWRT system, but if not:
# Set GatewayAddress to the IP address of the router on
# the GatewayInterface. This is the address that the Nodogsplash
# server listens on.
#
# GatewayAddress 192.168.1.1
# Parameter: ExternalInterface
# Default: Autodetected from /proc/net/route
#
# This should be autodetected on a OpenWRT system, but if not:
# Set ExtrnalInterface to the 'external' interface on your router,
# i.e. the one which provides the default route to the internet.
# Typically vlan1 for OpenWRT.
#
# ExternalInterface vlan1
# Parameter: RedirectURL
# Default: none
#
# After authentication, normally a user is redirected
# to their initially requested page.
# If RedirectURL is set, the user is redirected to this URL instead.
#
# RedirectURL http://www.ilesansfil.org/
# Parameter: GatewayPort
# Default: 2050
#
# Nodogsplash's own http server uses GatewayAddress as its IP address.
# The port it listens to at that IP can be set here; default is 2050.
#
# GatewayPort 2050
# Parameter: MaxClients
# Default: 20
#
# Set MaxClients to the maximum number of users allowed to
# connect at any time. (Does not include users on the TrustedMACList,
# who do not authenticate.)
#
# MaxClients 20
# ClientIdleTimeout
# Parameter: ClientIdleTimeout
# Default: 10
#
# Set ClientIdleTimeout to the desired of number of minutes
# of inactivity before a user is automatically 'deauthenticated'.
#
# ClientIdleTimeout 10
# Parameter: ClientForceTimeout
# Default: 360
#
# Set ClientForceTimeout to the desired number of minutes before
# a user is automatically 'deauthenticated', whether active or not
#
# ClientForceTimeout 360
# Parameter: AuthenticateImmediately
# Default: no
#
# Set to yes (or true or 1), to immediately authenticate users
# who make a http port 80 request on the GatewayInterface (that is,
# do not serve a splash page, just redirect to the user's request,
# or to RedirectURL if set).
#
# AuthenticateImmediately no
# Parameter: MACMechanism
# Default: block
#
# Either block or allow.
# If 'block', MAC addresses on BlockedMACList are blocked from
# authenticating, and all others are allowed.
# If 'allow', MAC addresses on AllowedMACList are allowed to
# authenticate, and all other (non-trusted) MAC's are blocked.
#
# MACMechanism block
# Parameter: BlockedMACList
# Default: none
#
# Comma-separated list of MAC addresses who will be completely blocked
# from the GatewayInterface. Ignored if MACMechanism is allow.
# N.B.: weak security, since MAC addresses are easy to spoof.
#
# BlockedMACList 00:00:DE:AD:BE:EF,00:00:C0:1D:F0:0D
# Parameter: AllowedMACList
# Default: none
#
# Comma-separated list of MAC addresses who will not be completely
# blocked from the GatewayInterface. Ignored if MACMechanism is block.
# N.B.: weak security, since MAC addresses are easy to spoof.
#
# AllowedMACList 00:00:12:34:56:78
# Parameter: TrustedMACList
# Default: none
#
# Comma-separated list of MAC addresses who are not subject to
# authentication, and are not restricted by any FirewallRuleSet.
# N.B.: weak security, since MAC addresses are easy to spoof.
#
# TrustedMACList 00:00:CA:FE:BA:BE, 00:00:C0:01:D0:0D
# Parameter: PasswordAuthentication
# Default: no
# Set to yes (or true or 1), to require a password matching
# the Password parameter to be supplied when authenticating.
#
#
# PasswordAuthentication no
# Parameter: Password
# Default: none
# Whitespace delimited string that is compared to user-supplied
# password when authenticating.
#
#
# Password nodog
# Parameter: UsernameAuthentication
# Default: no
# Set to yes (or true or 1), to require a username matching
# the Username parameter to be supplied when authenticating.
#
#
# UsernameAuthentication no
# Parameter: Username
# Default: none
# Whitespace delimited string that is compared to user-supplied
# username when authenticating.
#
#
# Username guest
# Parameter: PasswordAttempts
# Default: 5
# Integer number of failed password/username entries before
# a user is forced to reauthenticate.
#
#
# PasswordAttempts 5
# Parameter: TrafficControl
# Default: no
#
# Set to yes (or true or 1), to enable traffic control in Nodogsplash.
#
# TrafficControl no
# Parameter: DownloadLimit
# Default: 0
#
# If TrafficControl is enabled, this sets the maximum download
# speed to the GatewayInterface, in kilobits per second.
# For example if you have an ADSL connection with 768 kbit
# download speed, and you want to allow about half of that
# bandwidth for the GatewayInterface, set this to 384.
# A value of 0 means no download limiting is done.
#
# DownloadLimit 384
# Parameter: UploadLimit
# Default: 0
#
# If TrafficControl is enabled, this sets the maximum upload
# speed from the GatewayInterface, in kilobits per second.
# For example if you have an ADSL connection with 128 kbit
# upload speed, and you want to allow about half of that
# bandwidth for the GatewayInterface, set this to 64.
# A value of 0 means no upload limiting is done.
#
# UploadLimit 64
# Paramter: GatewayIPRange
# Default: 0.0.0.0/0
#
# By setting this parameter, you can specify a range of IP addresses
# on the GatewayInterface that will be responded to and managed by
# Nodogsplash. Addresses outside this range do not have their packets
# touched by Nodogsplash at all.
# Defaults to 0.0.0.0/0, that is, all addresses.
#
# GatewayIPRange 0.0.0.0/0
