ADFS 2.0 Client Access Redirect iRule

Hello,     I'm setting up Microsoft ADFS 2.0 in our environment and one requirement is to 1) handle load balancing for federation servers (inside our network) as well as 2) handle load balancing...

Ok, I figured this out with the help of F5 Support.

 

 

The biggest thing is that I just needed to edit the Virtual Server "Configuration" (Advanced) so the "SNAT Pool" is set to "Auto Map" to get the traffic to route properly back through the F5 BIG-IP Application Delivery Controller.

 

 

However, I also simplified the rule since the Virtual Server will only be contacted by users attempting to access our Federation Servers:

 

 

when CLIENT_ACCEPTED {

 

if { [IP::remote_addr] starts_with "10." } { pool ADFS_Internal_Pool }

 

elseif { [IP::remote_addr] starts_with "Public IP Range Matching Virtual Server IP." } { pool ADFS_Internal_Pool }

 

elseif { [IP::remote_addr] starts_with "192.168." } { pool ADFS_Internal_Pool }

 

elseif { [IP::addr [IP::remote_addr] equals 172.16.0.0/12] } { pool ADFS_Internal_Pool }

 

else { pool ADFS_External_Pool }

 

}
