return traffic route for source address

Hello,

 

I have single bigip, 4 vlan, 4 nodos in cluster, the traffic passing through them is not changed(devices act as transparent)

 

I have some questions to them describe the diagram, this aplication intenet mobile 3g, I am, distributing traffic by ip source,with irules on vs ipfw 0.0.0.0/0, that directs traffic from the GGSN to member_pool (vip cluster 1 or 2), the incoming traffic not changed when passing through f5 and then radius servers, this is fine, ggsn->router-> vs ipfw 0.0.0.0/0 -> vip cluster ---> f5 --- > Radius, the Return traffic is ok, this problem is when the cluster switches the slave --> master, there is traffic that not returns navegation. Have I to add some special configuration for the return of traffic when the servers switch???

 

Thanks

 

trace capture

 

example:

 

incoming 172.29.72.65.request >172.29.148.3.3789: rad-account-request 20 [id 162] (DF

 

0ut 172.29.148.3.radius-acct > 172.29.72.65.3789: rad-account-resp 20 [id 162] (DF)
