Hi Lobak,

 

as Alexandre already wrote, no iRule will be required.

 

But I guess there was no SNAT AutoMap configured for your virtual server.

 

Without SNAT the server will return the response according to it´s routing table.

 

If the server´s gateway does not point to the BIG-IP you will see an asymmetric traffic flow and the client will simply discard the responses (as they are not coming from the virtual server).

 

Applying SNAT will force all server´s responses through the BIG-IP.

 

Thanks, Stephan
