IPv6 Internet Protocol version 6 (IPv6) configuration has the following items: IPv6 support - FW_IPv6 (yes/no) IPv6 outgoing configuration - FW_IPv6_reject_outgoing (yes/no/drop) Examples: FW_IPv6" FW_IPv6_reject_outgoing"no" FW_IPv6 defaults to the ipv6 support by the Kernel when the option is empty.Network interface can be assigned to zones by adding the interface name to the of the.How do I display / list all rules in the selected chain?Examples: FW_DEV_EXT"dsl0 fW_DEV_EXT"any wlan0 fW_DEV_INT"eth0 wlan1 the special string any can be used to tell SuSEfirewall to assign all interfaces that are not listed anywhere to the specified zone.If no chain is selected, all chains are listed.By default all unassigned interfaces are automatically assigned to the external zone.Using this method is especially convenient if a service needs multiple ports.If a particular variable allows to assign more entries, they are separated by space.The following configuration creates a custom rules file that does the necessary changes to the system configuration.Drop all - /22 /0.
Cp /root/bin/ Run Yast's /etc/sysconfig editor Set to /root/bin/SuSEfirewall2-custom Edit In our example, we want big fish games new releases to add some code to the fw_custom_after_finished function: fw_custom_after_finished # these are the rules to be loaded after the firewall is fully configured for i in /proc/sys/net/ipv4/conf do setproc.
Examples: FW_services_EXT_TCP"ssh" FW_services_EXT_TCP"ftp 22 telnet 512:514" FW_services_EXT_UDP"631 400:405" Alternatively packages may provide a configuration file that describes which ports need to be opened to run a specific service, see.
But this choice will also switch off several other security options.
SuSEfirewall2 is a stateful network packet filter also known as firewall.
Non-working items SuSEfirewall2 does not support all its features on IPv6.Example: Allow the network on the internal interface full access to the net.Drop all - /0, dROP all - /0, dROP all - /0.Shutting down the Firewall SuSEfirewall2: Warning: ip6tables does not support state matching.This enables SuSEfirewall2 to act also as a network router between three different networks or rather a LAN server that provides masquerading to the Internet (or other network).So the format is a space separated list of net, protocol,dport, sport,flags Example # This /0 restricts access via IPv4 only Supported flags are: hitcountnumber : ipt_recent -hitcount parameter blocksecondsnumber : ipt_recent -seconds parameter recentnamename : ipt_recent -name parameter Example: # Allow max three ssh connects.For example, if you don't want the restrictive filtering of the external zone in your wlan, but also don't fully trust the wlan so you can't use the internal zone, you could define a new zone: FW_zones"wlan".Extended IPv6 support disabled.Although SuSEfirewall2 has many features, YaST can't obviously configure all of them.
