Wildcard Virtual Server question

ALL

 

I have a situation where I had define a wildcard virtual Forwarding ip with 0.0.0.0 network and any ports to allow to pass traffic for virtual servers not defined on f5. basically there are servers which had default route of LB and was used as router to pass traffic.

 

My question is in doing so will it affect any other vips and SNats or virtual server defined on the LB? It should not right? SO if I have a SNAT defined as snatpool with address translation 172.16.86.21 and address list 172.16.82.11 and 172.16.82.12 it should not affect this SNAT correct?

    A SNAT isn't a listener, and a virtual server won't be affected unless the client traffic matches its listening parameters. The general notion is that virtual servers are affected from most specific to least specific. For example, if you have two virtual servers, both wildcard (0.0.0.0/0), but one is listening on port 443 and the other on any port (0), port 443 client traffic will be answered by the more specific 443 VIP.
