#
# With this option you may allow access to e.g. your mailserver. The

#
# Please note that this should *not* be used for security reasons! You are

# is compromised - your full internal network is compromised!!
#
# Choice: leave empty (good choice!) or use the following explained syntax

# A forward masquerade rule consists of 1) source IP/net, 2) destination IP

FW_FORWARD_MASQ="" # Beware to use this!

# Keep the routing set on, if the firewall rules are unloaded?
# REQUIRES: FW_ROUTE
#
# If you are using diald, or automatic dialing via ISDN, if packets need

# not turn off routing and masquerading when stopped.
# You *might* also need this if you have got a DMZ.
# Please note that this is *insecure*! If you unload the rules, but are still

# Common: "ftp-data", better is "yes" to be sure that everything else works

# Are you running some of the services below?
# They need special attention - otherwise they wonŽt work!
#
# Set services you are running to "yes", all others to "no", defaults to "no"
#
FW_SERVICE_AUTODETECT="yes" # Autodetect the services below when starting
#
# If you are running bind/named set to yes. Remember that you have to open
# port 53 (or "domain") as udp/tcp to allow incoming queries.
# Also FW_ALLOW_INCOMING_HIGHPORTS_UDP needs to be "yes"
FW_SERVICE_DNS="no" #effies aangepast was yes!!!!
#
# if you use dhclient to get an ip address you have to set this to "yes" ! AANGEPAST!!! was no
FW_SERVICE_DHCLIENT="yes"
#
# set to "yes" if this server is a DHCP server
FW_SERVICE_DHCPD="no"

# 13.)
# Which services accessed from the internet should be allowed to the
# dmz (or internal network - if it is not masqueraded)?
# REQUIRES: FW_ROUTE
#
# With this option you may allow access to e.g. your mailserver. The
# machines must have valid, non-private, IP addresses which were assigned to
# you by your ISP. This opens a direct link to your network, so only use
# this option for access to your dmz!!!!
#
# Choice: leave empty (good choice!) or use the following explained syntax
# of forwarding rules, seperated each by a space.
# A forwarding rule consists of 1) source IP/net and 2) destination IP
# seperated by a comma. e.g. "1.1.1.1,2.2.2.2 3.3.3.3/16,4.4.4.4/24"
# Optional is a protocol, seperated by a comma, e.g. "5.5.5.5,6.6.6.6,igmp"
# Optional is a port after the protocol with a comma, e.g. "0/0,0/0,udp,514"
#
FW_FORWARD="" # Beware to use this!
#
# 14.)
# Which services accessed from the internet should be allowed to masqueraded
# servers (on the internal network or dmz)?
# REQUIRES: FW_ROUTE
#
# With this option you may allow access to e.g. your mailserver. The
# machines must be in a masqueraded segment and may not have public IP addesses!
# Hint: if FW_DEV_MASQ is set to the external interface you have to set
# FW_FORWARD from internal to DMZ for the service as well to allow access
# from internal!
#
# Please note that this should *not* be used for security reasons! You are
# opening a hole to your precious internal network. If e.g. the webserver there
# is compromised - your full internal network is compromised!!
#
# Choice: leave empty (good choice!) or use the following explained syntax
# of forward masquerade rules, seperated each by a space.
# A forward masquerade rule consists of 1) source IP/net, 2) destination IP
# (dmz/intern), 3) a protocol (tcp/udp only!) and 4) destination port,
# seperated by a comma (","), e.g. "4.0.0.0/8,1.1.1.1,tcp,80"
# Optional is a port after the destination port, to redirect the request to
# a different destination port on the destination IP, e.g.
# "4.0.0.0/8,1.1.1.1,tcp,80,81"
#
FW_FORWARD_MASQ="" # Beware to use this!
#
# 15.)
# Which accesses to services should be redirected to a localport on the
# firewall machine?
#
# This can be used to force all internal users to surf via your squid proxy,
# or transparently redirect incoming webtraffic to a secure webserver.
#
# Choice: leave empty or use the following explained syntax of redirecting
# rules, seperated by a space.
# A redirecting rule consists of 1) source IP/net, 2) destination IP/net,
# 3) protocol (tcp or udp) 3) original destination port and 4) local port to
# redirect the traffic to, seperated by a colon. e.g.:
# "10.0.0.0/8,0/0,tcp,80,3128 0/0,172.20.1.1,tcp,80,8080"
#
FW_REDIRECT=""
#
# 16.)
# Which logging level should be enforced?
# You can define to log packets which were accepted or denied.
# You can also the set log level, the critical stuff or everything.
# Note that logging *_ALL is only for debugging purpose ...
#
# Choice: "yes" or "no", FW_LOG_*_CRIT defaults to "yes",
# FW_LOG_*_ALL defaults to "no"
#
FW_LOG_DROP_CRIT="yes"
#
FW_LOG_DROP_ALL="no"
#
FW_LOG_ACCEPT_CRIT="yes"

# only change/activate this if you know what you are doing!
FW_LOG="--log-level warning --log-tcp-options --log-ip-option --log-prefix SuSE-FW"
#
# 17.)
# Do you want to enable additional kernel TCP/IP security features?
# If set to yes, some obscure kernel options are set.
# (icmp_ignore_bogus_error_responses, icmp_echoreply_rate,
# icmp_destunreach_rate, icmp_paramprob_rate, icmp_timeexeed_rate,
# ip_local_port_range, log_martians, mc_forwarding, mc_forwarding,
# rp_filter, routing flush)
# Tip: Set this to "no" until you have verified that you have got a
# configuration which works for you. Then set this to "yes" and keep it
# if everything still works. (It should!) ;-)
#
# Choice: "yes" or "no", defaults to "yes"
#
FW_KERNEL_SECURITY="yes"
#
# 18.)
# Keep the routing set on, if the firewall rules are unloaded?
# REQUIRES: FW_ROUTE
#
# If you are using diald, or automatic dialing via ISDN, if packets need
# to be sent to the internet, you need to turn this on. The script will then
# not turn off routing and masquerading when stopped.
# You *might* also need this if you have got a DMZ.
# Please note that this is *insecure*! If you unload the rules, but are still
# connected, you might your internal network open to attacks!
# The better solution is to remove "/sbin/SuSEfirewall2 stop" or
# "/sbin/init.d/firewall stop" from the ip-down script!
#
#
# Choices "yes" or "no", defaults to "no"
#
FW_STOP_KEEP_ROUTING_STATE="yes"
#
# 19.)
# Allow (or don't) ICMP echo pings on either the firewall or the dmz from
# the internet? The internet option is for allowing the DMZ and the internal
# network to ping the internet.
# REQUIRES: FW_ROUTE for FW_ALLOW_PING_DMZ and FW_ALLOW_PING_INTERNET
#
# Choice: "yes" or "no", defaults to "no" if not set
#
FW_ALLOW_PING_FW="yes"

#
# 20.)
# Allow (or don't) ICMP time-to-live-exceeded to be send from your firewall.
# This is used for traceroutes to your firewall (or traceroute like tools).
#
#
# Please note that the unix traceroute only works if you say "yes" to
# FW_ALLOW_INCOMING_HIGHPORTS_UDP, and windows traceroutes only if you say
# additionally "yes" to FW_ALLOW_PING_FW
#
# Choice: "yes" or "no", defaults to "no"
#
FW_ALLOW_FW_TRACEROUTE="yes"
#
# 21.)
# Allow ICMP sourcequench from your ISP?
#
# If set to yes, the firewall will notice when connection is choking, however
# this opens yourself to a denial of service attack. Choose your poison.
#
# Choice: "yes" or "no", defaults to "yes"
#
FW_ALLOW_FW_SOURCEQUENCH="yes"
#
# 22.)
# Allow/Ignore IP Broadcasts?
#
# If set to yes, the firewall will not filter broadcasts by default.
# This is needed e.g. for Netbios/Samba, RIP, OSPF where the broadcast
# option is used.
# If you do not want to allow them however ignore the annoying log entries,
# set FW_IGNORE_FW_BROADCAST to yes.
#
# Choice: "yes" or "no", defaults to "no"
#
FW_ALLOW_FW_BROADCAST="no"
#
FW_IGNORE_FW_BROADCAST="yes"
#
# 23.)
# Allow same class routing per default?
# REQUIRES: FW_ROUTE
#
# Do you want to allow routing between interfaces of the same class
# (e.g. between all internet interfaces, or all internal network interfaces)
# be default (so without the need setting up FW_FORWARD definitions)?
#
# Choice: "yes" or "no", defaults to "no"
#
FW_ALLOW_CLASS_ROUTING="no"
#
# 25.)
# Do you want to load customary rules from a file?
