Outbound SNAT matching inbound Virtual Servers

Hi,     Our customers are always asking us for a load balancing solution that provides bi-directional correspondence between a virtual server address (inbound) and the SNAT address being applied...

There really is no way in iRules to enumerate all pools and their members. You can get the list of members of a known pool name using the "active_members" command with the "-list" parameter. (Click here)

 

 

As cmbhatt mentions, you would need to create some relationship in the configuration between the source and the desired address translation for an outbound flow. The most reliable way is the class list he mentioned. You can alternatively build origin SNATs containing all the servers associated with each VS address, but they would have to be deleted & re-added if the list changes.

 

 

The simplest way would be if each customer has their own VLAN - you can apply a SNAT to only a specific VLAN, and it will translate all traffic arriving on that VLAN to the SNAT address.
