Problem mit Firewall

Bolle

Newbie
Hi!

Hab nen Suse Linux 9 Rechner hinter einem ADSL-Router. Auf dem Linux-Rechner läuft mldonkey. Die Ports für mldonkey hab ich im Router angegeben, klappt auch wunderbar bis dahin. Der Esel rennt bis dato ungehindert. Wenn ich aber suseFirewall2 einschalte bekomm ich ne LOW ID, obwohl ich die gleichen Ports in die Firewall eingetragen hab wie im Router. Sobald ich die Firewall abschalte funzt mldonkey wieder.
Was mach ich denn falsch?

Port TCP 51314 und UDP 51318 sollen die mldonkey ports sein.


## Path: Network/Firewall/SuSEfirewall2
## Description: SuSEfirewall2 configuration
## Type: yesno
## Default: no
## ServiceRestart: SuSEfirewall2_setup
#
# 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="wlan0"

## 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="no"

## 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="no"

## 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=""

## 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="yes"

## 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:

# For IP protocols (like GRE for PPTP, or OSPF for routing) you need to set
# FW_SERVICES_*_IP with the protocol name or number (see /etc/protocols)
#
# Choice: leave empty or any number of ports, known portnames (from
# /etc/services) and port ranges seperated by a space. Port ranges are

#
FW_SERVICE_AUTODETECT="yes"
# Autodetect the services below when starting

#
# 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

#
# Choice: leave empty (good choice!) or use the following explained syntax

# A forward masquerade rule consists of 1) source IP/net, 2) the IP to which

# Optional is an target IP address on which should the masquerading be decided.
# You have to set the optional port option to use this.

# Example:
# 200.200.200.0/24,10.0.0.10,tcp,80,81,202.202.202.202
# The class C network 200.200.200.0/24 trying to access 202.202.202.202 port
# 80 will be forwarded to the internal server 10.0.0.10 on port 81.
# Example:
# 200.200.200.0/24,10.0.0.10,tcp,80
# The class C network 200.200.200.0/24 trying to access anything which goes

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

# 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_DEV_EXT="ppp0"

Das kann nicht sein, ppp0 gibbed bei Routerbetrieb nicht, da mußt Du die NIC eintragen, die zum Router geht!

FW_PROTECT_FROM_INTERNAL="yes" kannste auf "NO" setzen

Sonst isses eigentlich richtig eingetragen.

BTW: Warum willste die Firewall überhaupt laufen haben, wenn Du eh' hinter eiinem Router sitzt?

Hi!

Supi funzt 1A! RIIIIIIIIIIIIIIIIIIEßEN DANKESCHÖN!!

Mein Router unterstützt leider nur NAT+ und hat keine integrierte Firewall und da is mir Port forwarding alleine n'bißchen heikel.
