Some of the numeric range and bit-field match conditions allow you to specify a text
synonym. For a list of all the synonyms for a match condition, do any of the following:
If you are using the J-Web Filters Configuration page, select the synonym from the
appropriate list.
If you are using the CLI, type a question mark (
To specify the bit-field value to match, you must enclose the values in quotation marks
( ). For example, a match occurs if the RST bit in the TCP flags field is set:
" "
tcp-flags "rst";
For information about logical operators and how to use bit-field logical operations to
create expressions that are evaluated for matches, see "Understanding Firewall Filter
Match Conditions" on page 3255.
On Juniper Networks EX Series Ethernet switches, you can apply a router firewall filter
to both IPv4 and IPv6 traffic. You can apply firewall filter match conditions to IPv6 traffic
on Layer 3 interfaces, aggregated Ethernet interfaces, and loopback interfaces. Table
417 on page 3244 describes the match conditions you can specify when configuring a firewall
filter for IPv6 traffic.
