1 Firewalld Thomas Woerner Red Hat, Inc. NFWS 2015 June 22
2 Introduction Central firewall management service using D-Bus Supports IPv4: iptables IPv6: ip6tables Bridges: ebtables Sends signals for all actions over D-Bus Run-time and persistent configuration Default configuration (fallbacks) Services Zones 2 firewalld NFWS 2015
3 Services Options Port (ranges) with protocol Netfilter helper modules Destination address (range) for IPv4 and/or IPv6 Nearly 70 built-in services Adaptable via D-Bus, files 3 firewalld NFWS 2015
4 Service Examples dns <service> <port protocol="tcp" port="53"/> <port protocol="udp" port="53"/> </service> tftp <service> <port protocol="udp" port="69"/> <module name="nf_conntrack_tftp"/> </service> https <service> <port protocol="tcp" port="443"/> </service> dhcpv6-client <service> <port protocol="udp" port="546"/> <destination ipv6="fe80::/64"/> </service> 4 firewalld NFWS 2015
5 Zones Options Services Ports (ranges) with protocols Rich language rules Internet Control Message Protocol (ICMP) blocks Masquerading Port/packet forwardings Completely adaptable 5 firewalld NFWS 2015
6 Zones Zone can be seen as a complete firewall Initial default: public One zone per connection with NetworkManager ZONE=<name> in ifcfg file or NM configuration One zone per interface or source address (range) Internal firewall rule ordering according to action log deny allow 6 firewalld NFWS 2015
7 Zone Examples public <zone> <service name="ssh"/> <service name="dhcpv6-client"/> </zone> drop <zone target= DROP > </zone> custom <zone> <interface name="em2"/> <source address=" /24"/> <service name="ssh"/> <service name="ipp-client"/> <service name="dhcpv6-client"/> <rule><protocol value="ah"/><accept/></rule> </zone> 7 firewalld NFWS 2015
8 Rich Rules Source address (range): optional Destination address (range): optional One Element Service, port, protocol, icmp-block, masquerade, forwardport Limit: optional Logging: optional Log and/or audit Limit: optional One Action: accept, reject, drop Limit optional 8 firewalld NFWS 2015
9 Rich Rules Examples Allow new IPv4 and IPv6 connections for service ftp and log 1 per minute using audit rule service name="ftp" log limit value="1/m" audit accept Allow new IPv4 connections from address /24 for service tftp, log 1 per minute using syslog rule family="ipv4" source address=" /24" service name="tftp" log prefix="tftp" level="info" limit value="1/m" accept New IPv6 connections from 1:2:3:4:6:: to service radius are rejected and logged at a rate of 3 per minute. New IPv6 connections from other sources are accepted rule family="ipv6" source address="1:2:3:4:6::" service name="radius" log prefix="radius" level="info" limit value="3/m" reject rule family="ipv6" service name="radius" accept 9 firewalld NFWS 2015
10 Direct Interface More complex rules, globally, not in zones Rules ip*tables/ebtables syntax priority for rule ordering added to _direct chains for netfilter built-in chains or own chains Passthrough rules (For highly experienced users) Used by libvirt and docker 10 firewalld NFWS 2015
11 Direct Interface Examples Create custom chain blacklist in raw table for IPv4, log and DROP firewall-cmd --direct --add-chain ipv4 raw blacklist firewall-cmd --direct --add-rule ipv4 raw blacklist 0 -m limit --limit 1/min -j LOG --log-prefix blacklist: firewall-cmd --direct --add-rule ipv4 raw blacklist 1 -j DROP Add black listed IPv4 address to blacklist firewall-cmd --direct --add-rule ipv4 raw PREROUTING 0 -s /24 -j blacklist Persistent direct configuration <?xml version="1.0" encoding="utf-8"?> <direct> <chain ipv="ipv4" table="raw" chain="blacklist"/> <rule ipv="ipv4" table="raw" chain="prerouting" priority="0">-s /24 -j blacklist</rule> <rule ipv="ipv4" table="raw" chain="blacklist" priority="0">-m limit --limit 1/min -j LOG --log-prefix "blacklist: "</rule> <rule ipv="ipv4" table="raw" chain="blacklist" priority="1">-j DROP</rule> </direct> 11 firewalld NFWS 2015
12 Future Plans Tracing mode ipset support Security environments (zone interaction) Direct rules in zones nftables support 12 firewalld NFWS 2015
