Translate port how does it work

If there is a VIP with 1.2.3.4:80 service 80 and pool memebers also with same port 80 . Then will this setup work with translate port enabled ?

Yes that should work. Port translation is enabled by default and allows the virtual server to send traffic to whichever port has been configured on the pool members (in situations where the VIP port is different from the pool member port e.g. SSL offload).

 

Because when above configuration is applied this sends request to some different port on the same server in my case port 82 .

I know of no reason why that would happen. It's definitely not normal.

 

When i disabled port translation then it started going to the current service 80 on the back end server .

That is expected since the VIP and pool member are using the same port number port translation is not required.

 

Is this the only VIP that is experiencing this issue?

 

Is this a "standard" type vip?

 

Are there any irules, local traffic policies, or profiles assigned to the vip?

 

Hi Scott,

 

thanks for reply .

 

these are the setting on virtual : virtual abc { translate service disable pool abc destination 1.2.3.4:http ip protocol tcp rules SNAT2VIP persist source_1800 profiles { http-xff {} tcp-lan-optimized { serverside } tcp-wan-optimized { clientside } } }

 

no irules , only this VIp .

 

Thanks

 

rules SNAT2VIP

This means there is an iRule named SNAT2VIP assigned to this vip. Can you post the code of that iRule?

 

can you post persistence and pool configurations?

 tmsh list ltm pool abc
 tmsh list ltm persistence source-addr source_1800

Hi after looking at this post, i have a question on pool configuration

 

Can we configure a pool members serving same services on different ports under a same pool?

 

EX: PL_Test

 

1.1.1.1:6700 1.1.1.1:6705

 

Please suggest me.

 

Thanks.
