We do use SNAT - this NATs the source to the egress interface on the LTM.

The issue is that when the proxy gets the traffic it will forward to a new destination IP.

 

 

 

So even though the LTM SNATs using its floating IP, the Proxy forwards to a new IP, outside of the subnet and hence bypasses the LTM due to the default gateway not being the LTM.

 

 

 

If the proxies use the LTM as their default gateway the LTM would need to have some more routing smarts that is currently configured on our one.
