NimbostratusChange source IP address of outgoing traffic
I have a server which I would like the source IP to change per flow/conversation. Ideal situation is the source IP would be taken from a pool. I'm still learning iRules and any help would be appreciated! I want each conversation to have a different source. even if the destination is the same.

Take a look at the snat

and snatpool commands

With these you can dynamically assign a single SNAT IP or one from a pool that will effectively change the source address of that connection.
giltjrWhich IP address?
Client <---- Address1 ---> F5 <----- Address2 -----> Pool Member
Do you want the IP address that the F5 uses to communicate with the client with (Address 1, also the VIP address) to change?
Or do you want the IP address that the F5 uses to communicate the the pool member (Address 2) to change?
What type of traffic is this, HTTP, SSH, FTP, something else? The reason I ask this is that for HTTP you may add overhead to both the F5 and the pool member by doing this.
