    Dear Sir,

    I am beginer in Juniper.I would lke to know how to clustering IPS devices.

    I want to use SRX 1500 as IPS device.

    i have experience in SRX 340 clustering.

    But i don't know how to cluster IPS.And I don't want to change my network design and IP addressing.

    I mean in firewalls,i can use transparent mode for my design.i don't i can't use or not tranparent is support in IPS .

    Please help me  and explain or if can i get reference links,please provide me.

    Hello,

     

    I do not think SRX340 and SRX1500 chassis clustering and IDP support has any difference.

    I also came across few instances where SRX1500 cluster was configured in transparent mode.

     

    Regards,

    Yes, there are a number of feature restrictions in the various chassis cluster modes.  One of them is that bridge domains cannot be used in transparent mode chassis cluster. 

    This is listed at the top of page 46 in the detailed  Chassis Cluster feature guide.

    Hi,

    i would like to create IPS HA active acitive (in tranparent mode) for two router.

    Please see i prepare below configuration. It is correct or not ?

    I haven't done layer two zones in a while so I don't have the details handy.  But the security zone assignments are by subinterface so these need to include the dot and unit number.

    set security zones security-zone outside interfaces reth0
    set security zones security-zone outside interfaces reth2
    set security zones security-zone inside interfaces reth1
    set security zones security-zone inside interfaces reth3

    And of course the vlans need to be configured.

    And the reth ports placed in trunk mode.
