## Path: Network/Firewall/SuSEfirewall2 ## Description: SuSEfirewall2 configuration ## Type: yesno ## Default: no # # 1.) # Should the Firewall run in quickmode? # # "Quickmode" means that only the interfaces pointing to external networks # are secured, and no other. all interfaces not in the list of FW_DEV_EXT # are allowed full network access! Additionally, masquerading is # automatically activated for FW_MASQ_DEV devices. and last but not least: # all incoming connection via external interfaces are REJECTED. # You will only need to configure 2.) and FW_MASQ_DEV in 6.) # Optionally, you may add entries to section 9a.) # # Choice: "yes" or "no", if not set defaults to "no" # FW_QUICKMODE="no"

## Type: string # 2.) # Which is the interface that points to the internet/untrusted networks? # # Enter all the network devices here which are untrusted. # # Choice: any number of devices, seperated by a space # e.g. "eth0", "ippp0 ippp1 eth0:1" # FW_DEV_EXT="ppp0"

## Type: string # # 3.) # Which is the interface that points to the internal network? # # Enter all the network devices here which are trusted. # If you are not connected to a trusted network (e.g. you have just a # dialup) leave this empty. # # Choice: leave empty or any number of devices, seperated by a space # e.g. "tr0", "eth0 eth1 eth1:1" or "" # FW_DEV_INT="eth0"

## Type: string # # 4.) # Which is the interface that points to the dmz or dialup network? # # Enter all the network devices here which point to the dmz/dialups. # A "dmz" is a special, seperated network, which is only connected to the # firewall, and should be reachable from the internet to provide services, # e.g. WWW, Mail, etc. and hence are at risk from attacks. # See /usr/share/doc/packages/SuSEfirewall2/EXAMPLES for an example. # # Special note: You have to configure FW_FORWARD to define the services # which should be available to the internet and set FW_ROUTE to yes. # # Choice: leave empty or any number of devices, seperated by a space # e.g. "tr0", "eth0 eth1 eth1:1" or "" # FW_DEV_DMZ=""

## Type: yesno ## Default: no # # 5.) # Should routing between the internet, dmz and internal network be activated? # REQUIRES: FW_DEV_INT or FW_DEV_DMZ # # You need only set this to yes, if you either want to masquerade internal # machines or allow access to the dmz (or internal machines, but this is not # a good idea). This option supersedes IP_FORWARD from # /etc/sysconfig/network/options # # Setting this option one alone doesn't do anything. Either activate # massquerading with FW_MASQUERADE below if you want to masquerade your # internal network to the internet, or configure FW_FORWARD to define # what is allowed to be forwarded! # # Choice: "yes" or "no", if not set defaults to "no" # FW_ROUTE="yes"

## Type: yesno ## Default: no # # 6.) # Do you want to masquerade internal networks to the outside? # REQUIRES: FW_DEV_INT or FW_DEV_DMZ, FW_ROUTE # # "Masquerading" means that all your internal machines which use services on # the internet seem to come from your firewall. # Please note that it is more secure to communicate via proxies to the # internet than masquerading. This option is required for FW_MASQ_NETS and # FW_FORWARD_MASQ. # # Choice: "yes" or "no", if not set defaults to "no" # FW_MASQUERADE="yes"

## Type: string # # You must also define on which interface(s) to masquerade on. This is # normally your external device(s) to the internet. # Most users can leave the default below. # # e.g. "ippp0" or "$FW_DEV_EXT" FW_MASQ_DEV="$FW_DEV_EXT"

## Type: string # # Which internal computers/networks are allowed to access the internet # directly (not via proxys on the firewall)? # Only these networks will be allowed access and will be masqueraded! # # Choice: leave empty or any number of hosts/networks seperated by a space. # Every host/network may get a list of allowed services, otherwise everything # is allowed. A target network, protocol and service is appended by a comma to # the host/network. e.g. "10.0.0.0/8" allows the whole 10.0.0.0 network with # unrestricted access. "10.0.1.0/24,0/0,tcp,80 10.0.1.0/24,0/0tcp,21" allows # the 10.0.1.0 network to use www/ftp to the internet. # "10.0.1.0/24,tcp,1024:65535 10.0.2.0/24" is OK too. # Set this variable to "0/0" to allow unrestricted access to the internet. # FW_MASQ_NETS="0/0"

## Type: yesno ## Default: yes # # 7.) # Do you want to protect the firewall from the internal network? # REQUIRES: FW_DEV_INT # # If you set this to "yes", internal machines may only access services on # the machine you explicitly allow. They will be also affected from the # FW_AUTOPROTECT_SERVICES option. # If you set this to "no", any user can connect (and attack) any service on # the firewall. # # Choice: "yes" or "no", if not set defaults to "yes" # # "yes" is a good choice FW_PROTECT_FROM_INTERNAL="no"

## Type: yesno ## Default: yes # # 8.) # Do you want to autoprotect all running network services on the firewall? # # If set to "yes", all network access to services TCP and UDP on this machine # will be prevented (except to those which you explicitly allow, see below: # FW_SERVICES_{EXT,DMZ,INT}_{TCP,UDP}) # # Choice: "yes" or "no", if not set defaults to "yes" # FW_AUTOPROTECT_SERVICES="yes"

REJECTing means, that # for every illegal packet, a connection reject packet is sent to the # sender. # # Choice: "yes" or "no", if not set defaults to "no" # FW_REJECT="no"

## Type: string # # 27.) # Tuning your upstream a little bit via HTB (Hierarchical Token Bucket) # for more information about HTB see http://www.lartc.org # # If your download collapses while you have a parallel upload, # this parameter might be an option for you. It manages your # upload stream and reserves bandwidth for special packets like # TCP ACK packets or interactive SSH. # It's a list of devices and maximum bandwidth in kbit. # For example, the german TDSL account, provides 128kbit/s upstream # and 768kbit/s downstream. We can only tune the upstream. # # Example: # If you want to tune a 128kbit/s upstream DSL device like german TDSL set # the following values: # FW_HTB_TUNE_DEV="ppp0,125" # where ppp0 is your pppoe device and 125 stands for 125kbit/s upstream # # you might wonder why 125kbit/s and not 128kbit/s. Well practically you'll # get a better performance if you keep the value a few percent under your # real maximum upload bandwidth, to prevent the DSL modem from queuing traffic in # it's own buffers because queing is done by us now. # So for a 256kbit upstream # FW_HTB_TUNE_DEV="ppp0,250" # might be a better value than "ppp0,256". There is no perfect value for a # special kind of modem. The perfect value depends on what kind of traffic you # have on your line but 5% under your maximum upstream might be a good start. # Everthing else is special fine tuning. # If you want to know more about the technical background, # http://tldp.org/HOWTO/ADSL-Bandwidth-Management-HOWTO/ # is a good start # FW_HTB_TUNE_DEV=""
