Load Balancing with External Pool members

Hi Manny,

 

 

Make sure to add a TMM route to the non-local hosts and use SNAT (automap is simplest) on the virtual server.

Hello Aaron,

 

 

I did, and it worked,, I can balance traffic on external nodes, thanks!, now, the only problem is that those servers use Google Analytics,, now it seems Im hitting them with my LTM IP, instead of with the customers IP.

 

Im afraid the stats are going to be affected.

 

 

 

I wonder is that has a workaround.

 

 

 

Thanks

If you make the LTM the gateway for your servers, then you won't need to snat the traffic and the source IP will be visible for your servers. Otherwise, you can in the HTTP profile (or in an iRule, but go with the profile first) insert the X-Forwarded-For header which will pass the client IP to the server. Your servers will need to be configured to retrieve from the header.

I cannot make the LTM the default gateway, because the Nodes are on the Internet with Public IPs, (hosted on Third-Party web hosting facilities).

 

 

But I like the other option, about "retrieving the IP from the header",, and I think I can work on the iRule.

 

 

Is there documentation on how to do that on Apache and Tomcat?

 

The Nodes are administered by someone else and I will need to tell them what to do or where to find information about that.

 

And those are the servers they run.

 

 

 

Thanks

Hi Manny,

 

 

SOL4816 has details on how Apache and IIS can parse the XFF header for logging. It might be possible to adapt that for Google Analytics.

Thanks a lot Aaron,

 

 

I will take a look at that
