Cisco ACE - NAT bounce back rule for ORACLE

[CSCO11061734]

Hi Kanwal,

With reference to the previous thread.

Please find below the answers to the questions you had posted.

1) What is the initial URL client will come with?

http://ofrv.a.b/portal/page    The client types in this URL which redirects to the URL mentioned in the 2nd question.

2) Is it just going to redirect it to http://ofrv.a.b/portal/page or https://ofrv.a.b/portal/page?

http://ofr1.a.b:8090 and http://ofr2.a.b:8090

The real IPs are 172.x.x.114 and 172.x.x.115 respectively.

What are the servers to which the traffic would be loadbalanced?

172.x.x.114 and 172.x.x.115 respectively are the real servers.  The client accesses the VIP 172.x.x.140 on 80.

Is this the serverfarm?

YES.  This is the serverfarm.  

I apologize for starting a new thread here.  But I'm unable to update that thread due to site maintenance.

Hi Sbegum,

I have a VIP redirecting to 2 real servers 172.x.x.114 and 115 respectively. The url to be accessed is

http://ofrv.a.b/portal/page. This has to be redirected to the 2 servers on ofr1.a.b and ofr2.a.b on port 8090.

Few questions:

1) What is the initial URL client will come with?

2) Is it just going to redirect it to http://ofrv.a.b/portal/page or https://ofrv.a.b/portal/page?

What are the servers to which the traffic would be loadbalanced?

Is this the serverfarm?

serverfarm host Reports-SF2-5

  probe OFR-HTTP3

  probe OFR-HTTP4

  rserver OFR1-Server 8090

    probe ICMP_PROBE1

    inservice

  rserver OFR2-Server 8090

    probe ICMP_PROBE1

    inservice

Let me know and i will send a configuration sample.

Do I require a NAT statement in the configuration.  If yes what should it be ?  The loadbalancer and the client IP's gateway is 172.x.1.1.

Any help is greatly appreciated.

Thanks and regards

Hi,

These are two different URL's.

http://ofr1.a.b:8090 and http://ofr2.a.b:8090 which means that  you would need two different VIP's plus you cannot have two redirect URL's. Let's say you come with http://ofrv.xxx.com then ACE can redirect you to http://ofrv.xxx.com/test but it cannot redirect to two different URL's unless the client itself is coming with two different URL's on two different VIPS.

Hi,

Please note that we cannot have two different VIP's as the client will access only one link.  If there cannot be two different redirect URL's then what is the other way to configure this requirement.  The cisco ACE has to load balance between Real IPs 114 and 115. 

Please advise.

Thanks and regards

Hi Sbegum,

We can match different host names using class-map type http and using HOST header value but i do not think of a way for  ACE to redirect client URL to two different URL's. I don't see the logic why the user who is coming with same URL should be redirected to two different URL's? What are we achieving with that?

May be if we know the full requirment we can think of a way to work on it.

Kanwal
