I made two changes now.

 

 

1) On the virtual-address 0.0.0.0 i enabled ICMP-Echo.

 

This now allows me to ping across the wildcard virtual server for the proxies to access the internet etc.

 

 

2) I then set SNAT to Automap and now everything works.

 

 

So basically for me to disable SNAT Automap i will need to create a route on the routers that route all proxies traffic to the F5?

I know this is a little old, but I just want to make very clear that, when you enable ICMP-Echo on a 0.0.0.0 Virtual-Address, you are not actually performing a ping Through the BIG-IP. The virtual-address is responding directly. And because 0.0.0.0 will encompass ALL IP Addresses, this means that the BIG-IP will ICMP Respond to ALL IP Addresses This is generally an undesired behavior, and can cause a large amount of confusion.
