Need help with a SNAT irule

Hello all.

 

 

I need some help with a SNAT irule for the Exchange implementation with F5.

 

According to the F5 Exchange document; I need a SNAT irule so that the exchange clients get NATed to the same IP address while connecting to the exchange VIP.

 

 

I created a SNAT pool with 9 IP addresses (10.162.93.38 to 10.162.93.46) and applied the SNAT pool to the Exchange VIP, I also created the irule below to use the SNAT pool:

 

 

when CLIENT_ACCEPTED { snat 10.162.93[expr ( [getfield [IP::client_addr] "." 4] % 9 ) 1 ] }

 

 

It doesn't work. the clients don't get NATed to an IP on the SNAT pool Please Help!!!
