shorewall-exclusion 5 exclusion Exclude a set of hosts from a definition in a shorewall configuration file. !address-or-range[,address-or-range] Exclusion is used when you wish to exclude one or more addresses from a definition. An exclaimation point is followed by a comma-separated list of addresses. The addresses may be single host addresses (e.g., 192.168.1.4) or they may be network addresses in CIDR format (e.g., 192.168.1.0/24). If your kernel and iptables include iprange support, you may also specify ranges of ip addresses of the form lowaddress-highaddress No embedded whitespace is allowed. Exclusion can appear after a list of addresses and/or address ranges. In that case, the final list of address is formed by taking the first list and then removing the addresses defined in the exclusion. Example 1 - All IPv4 addresses except 192.168.3.4 !192.168.3.4 Example 2 - All IPv4 addresses except the network 192.168.1.0/24 and the host 10.2.3.4 !192.168.1.0/24,10.1.3.4 Example 3 - All IPv4 addresses except the range 192.168.1.3-192.168.1.12 and the network 10.0.0.0/8 !192.168.1.3-192.168.1.12,10.0.0.0/8 Example 4 - The network 192.168.1.0/24 except hosts 192.168.1.3 and 192.168.1.9 192.168.1.0/24!192.168.1.3,192.168.1.9 /etc/shorewall/hosts /etc/shorewall/masq /etc/shorewall/rules /etc/shorewall/tcrules shorewall(8), shorewall-accounting(5), shorewall-actions(5), shorewall-blacklist(5), shorewall-hosts(5), shorewall-interfaces(5), shorewall-maclist(5), shorewall-masq(5), shorewall-nat(5), shorewall-netmap(5), shorewall-params(5), shorewall-policy(5), shorewall-providers(5), shorewall-proxyarp(5), shorewall-route_rules(5), shorewall-routestopped(5), shorewall-rules(5), shorewall.conf(5), shorewall-tcclasses(5), shorewall-tcdevices(5), shorewall-tcrules(5), shorewall-tos(5), shorewall-tunnels(5), shorewall-zones(5)
