CSS11503 to ACE4710 and server side NAT

Hello everyone,

We have a CSS11503 that is currently being used to accept incoming HTTPS and SSH connections on a specific VIP and then PAT those client connections.  I understand that it also PATs the server initiated connections.

I converted the configuration using the CCS-to-ACE configuration tool, added lines for logging, and switched over to it.  Now, the server initiated traffic is apparently not having the PAT applied.  The "range" portion of the "ip address 10.yyy.yyy.34 range 14" and "ip address 10.yyy.yyy.2 range 30" didn't translate, so I can add those ranges as rservers in the ACE4710.

Here is the current "in progress" configuration for the ACE4710.  Please note the we currently have only one server for incoming connections for testing purposes.  After I add the remaining rservers for the ranges, will this be an equivaqlent configuration to the CSS11503 configuration above?

Question: Here is the current "in progress" configuration for the ACE4710.  Please note the we currently have only one server for incoming connections for testing purposes.  After I add the remaining rservers for the ranges, will this be an equivaqlent configuration to the CSS11503 configuration above?

You need to do two things.

1) Add the remaining rservers for the ranges.

2) Put them in serverfarm.

For example :

rserver host vsuiteFrontEnd-B

  inservice

  ip address 10.yyy.yyy.4

  probe SERVICE_ICMP_PROBE

serverfarm host rule-vsuiteFrontEnd-A

  probe SERVICE_ICMP_PROBE

  rserver vsuiteFrontEnd-A

    inservice

  rserver vsuiteFrontEnd-B

    inservice

That should help you to achieve your desired result.

Hope that helps.

regards,

Ajay Kumar
