A list of firewall rule examples for IPv4 and IPv6 addresses.
The following statements are examples of firewall rules.
If you do not specify a protocol, the rule assumes and uses the “any”
protocol.
IPv4 examples
- adapter A ip src addr xxx.xxx.x.x
- x is a number in the IP address
- adapter A ip src addr xxx.xxx.x dst addr any tcp
src port 20 dst port 80
- x is a number in the IP address
- adapter any ip src addr any dst addr xxx.xxx.xx.x
- adapter any ip src addr any dst addr any icmp type
8
- tcp
- adapter B icmp
- udp
IPv6 examples
- adapter A ipv6 src addr x:x:x:x:x:x:x:x
- x is one to four hexadecimal digits of the eight 16 bit pieces
of the IP address
- adapter A ipv6 src addr x:x:x:x:x:x:x:x dst addr
any tcp src port 20 dst port 80
- x is one to four hexadecimal digits of the eight 16 bit pieces
of the IP address
- adapter any ipv6 src addr any dst addr x:x:x:x:x:x:x:x
- adapter any ipv6 src addr any dst addr any icmpv6
type 128
- ipv6 tcp
- adapter B icmpv6
- udp
