The value of the object tIPFilterChainToSystemFilter specifies whether this filter policy is chained to the active IP system filter policy. The active IP system filter policy is defined as a row in tFilterSystemFilterTable that have the value of the object tFilterSystemFilterType set to 'fltrtypeselIp(1)'. The value 'true(1)' means this filter policy is chained to the active IP system filter policy. The system filter policy's rules are executed first before any rules of this filter policy are executed. The value of this object can be set to 'true(1)' only when the scope of this policy (value of the object tIPFilterScope) is 'exclusive(1)' or 'template(2)'. The value 'false(2)' means this filter policy is not chained to the active IP system filter policy.
