Snat-translation all statistics = zero

Hi, I've configured a typical snat that i'm using for a couple of 'internal' hosts to translate to an address on the 'external' vlan which happens to be a vip address.

 

When doing a tcpdump I can see traffic hit the f5 and then translate the source, it looks good. But the snat statistics do not show anything.

 

running v11.4.1 Only other configuration on the box of note is an ip forward 0.0.0.0/0 with no snat configured on it.

    I've done some further testing, on v11.3.0, and it looks like the following takes place: 1/ Ip forwarding will have precedence over the snat in regards to processing the traffic 2/ if the ip forwarder has a snat it will also have precedence 3/ if the ip forwarder does not have a snat attached then the global snat will convert the source address on the traffic allowed through via the ip forwarder.

     

    Statistics back this up as well on v11.3.0, but not on v11.4.1 Statistics show, traffic increments on ip forwarder VS. if no snat applied to ip forwarder: Statistics show, traffic increments on snat-translations on 11.3.0, not on v11.4.1
