Modifying a rule in a policy
You can modify a rule within an existing policy.
After logon, you must first search for the policy using the filtering feature:
 
		GET http://localhost:8082/7.2.1/elements/fw_policy?filter=HQ Policy 
	 
After the policy is found, you can retrieve a specific type of rule with the following request:
 
		http://localhost:8082/7.2.1/elements/fw_policy/56 
	 
 
		GET http://localhost:8082/7.2.1/elements/fw_policy/56 
	 
- fw_ipv4_access_rules — Retrieves all Engine IPv4 Access rules
- fw_ipv6_access_rules — Retrieves all Engine IPv6 Access rules
- fw_ipv4_nat_rules — Retrieves all Engine IPv4 NAT rules
- fw_ipv6_nat_rules — Retrieves all Engine IPv6 NAT rules

        "comment": "Set logging default, set long timeout for SSH connections",
        "is_disabled": false,
        "key": 2543,
        "link":
        [
            {
                "href": "http://localhost:8082/7.2.1/elements/fw_policy/56/fw_ipv4_access_rule/514",
                "rel": "self",
                "type": "fw_ipv4_access_rule"
            }
        ],
        "parent_policy": "http://localhost:8082/7.2.1/elements/fw_policy/56",
        "rank": 4,
        "read_only": false,
        "system": false,
        "tag": "514.0"
}The result has ETag: MjU0Mzk4MTEzMDYyMzMyMzYxMTg= as the HTTP response header.
This rule seems to be a comment rule (no source/destination/service attributes are defined), so you could update the comment, for example:
 
		PUT http://localhost:8082/7.2.1/elements/fw_policy/56/fw_ipv4_access_rule/514 
	 
The new JSON content with the updated comment and If-Match: MjU0Mzk4MTEzMDYyMzMyMzYxMTg= as the HTTP request header returns a 200 HTTP response status code and the following in
            the HTTP response header: 
 
		http://localhost:8082/7.2.1/elements/fw_policy/56/fw_ipv4_access_rule/514
