# Uruk version compatibility of this rc file
# (actually, likely works with version=20071030 too)
version=20140319

# Log denied packets, which are targetted at one of our IPs.  Do not log
# blocked broadcasts.

###############################
# define our network interfaces
###############################

# List of network interfaces.  lo should not be in this list (see below). For
# every interface <if>, variables ip_<if>, bcast_<if> and net_<if> should be
# defined.
interfaces="eth0 eth1"

# List of network interfaces we want uruk to leave alone: all traffic on these
# interfaces will be trusted and accepted.  By default, interfaces_unprotect=lo
#
interfaces_unprotect="lo sit0 eth3"


###############################################
# assign IPs and networks to network interfaces
###############################################

# this helper sets ip_<if> and net_<if>
. /lib/uruk/init/autodetect-ips

# alternatively, explicitly list adresses manually, by setting ip_<stuff>,
# ip6_<stuff>, net_<stuff> and net6_<stuff>, like this:

ips_eth0=default
# For each interface <if> in interfaces, ip_<if> and net_<if> should be
# defined

# 192.168.0.0/16 (aka 192.168./16) . Used to decide wether a
# packet for this interface is spoofed, and therefore should get dropped.

# full names only.

#####################################################
# finally, define allowed services, sources and ports

# in a variable ports_<if>_{tcp,udp}_<s> .

# A valid source is 192.168.6.26, another valid source is 192.168.6.0/24.
# One can add DNS domainnames like gandalf.example.com too: iptables will
# perform a DNS lookup
# Supply IPv6 addresses like e.g. this:
