DFW-L2-Regeln zeigen unbekannte MAC-Adresse
Nach der Konfiguration einer Layer-2-Firewallregel mit einem MAC Set als Quelle und einem anderen als Ziel festgelegten MAC zeigt der Befehl „getrules“ auf dem Host das Ziel-MAC Set als 01:00:00:00:00:00/01:00:00:00:00:00 an. Beispiel:
[root@host1:~] vsipioctl getrules -f nic-1000052822-eth1-vmware-sfw.2
ruleset mainrs {
# generation number: 0
# realization time : 2018-07-26T12:42:28
rule 1039 at 1 inout protocol tcp from any to any port 1521 accept as oracle;
# internal # rule 1039 at 2 inout protocol tcp from any to any port 1521 accept;
rule 1039 at 3 inout protocol icmp from any to any accept;
rule 2 at 4 inout protocol any from any to any accept with log;
}
ruleset mainrs_L2 {
# generation number: 0
# realization time : 2018-07-26T12:42:28
rule 1040 at 1 inout ethertype any stateless from addrset d83a1523-0d07-4b18-8a5b-77a634540b57 to addrset 9ad9c6ef-c7dd-4682-833d-57097b415e41 accept;
# internal # rule 1040 at 2 in ethertype any stateless from addrset d83a1523-0d07-4b18-8a5b-77a634540b57 to addrset 9ad9c6ef-c7dd-4682-833d-57097b415e41 accept;
# internal # rule 1040 at 3 out ethertype any stateless from addrset d83a1523-0d07-4b18-8a5b-77a634540b57 to mac 01:00:00:00:00:00/01:00:00:00:00:00 accept;
rule 1 at 4 inout ethertype any stateless from any to any accept;
}
Die interne OUT-Regel mit der Adresse 01:00:00:00:00:00/01:00:00:00:00:00 wird standardmäßig so erstellt, dass ausgehende Broadcast-Pakete verarbeitet werden, und weist kein Problem auf. Die Firewall-Regel funktioniert wie konfiguriert.
