BIG IP <-> Internal VLAN <-> Cisco SW's <-> Serversoutside network is on another side of bigip, isn't it?
When ever we ping from outside network to those servers, I can see traffic hitting one of the self IP's but after that it times out.when pinging server, does it hit NAT or another object e.g. SNAT, virtual server?
