Not reassembling fragmented packets to the same Pool member

Hello Community,

 

We have configured a standard VS with an irule that is checking ISO8583 frames on the packet to make the forwarding decision which is working fine when we received not fragmented packets.

 

At some point we started to receive packets that are being fragmented(same server source) on the network coming to the same VS however in this case at the back end side we are seeing that complement from that fragmented packet is being treated like a different packet thus is being sent to a different pool member which responds with a RST.

 

Is there any way to reassemble the packet and send all that fragmented sequence to the same pool member?

 

Thank you for all your responses.
