Ebtables examples

EBTables can filter EtherTypes that IPTables can't. For example, there are no IPTables filters that can specifically drop X25 or NetBEUI or IPX frames. At the same time, an IPTables rule can specify to drop all packets, except IPv4. In such a case, IPTables drops all packets other than IPv4 packets, but I don't understand whether the same. For example we can specify that frames received on interface eth0 should be brouted - they will be firewalled in higher OSI layers, for example by iptables. Rules & chains & tables: Ebtables uses rules to decide what action to perform with frames. These rules are grouped into chains, and these are grouped into tables. Write your password, hit Enter, and get the list of iptables rules and their specification as shown in the presented output image below. $ sudo iptables -S.
