Overview of Match Conditions in Firewall Filter Terms
In the from statement in a firewall filter term, you specify characteristics that the packet must have for the action in the subsequent then statement to be performed. The characteristics are referred to as match conditions. The packet must match all conditions in the from statement for the action to be performed, which also means that their order in the from statement is not important.
Each protocol family supports a different set of match conditions, and some match conditions are supported only on certain routers. For example, a number of match conditions for VPLS traffic are supported only on the MX Series Ethernet Services Routers.
