Can ping Self-IPs but cannot ping VirtualIPs
We've set up a new interface for internal load balancing on our BIG-IP 3600s.
New VLAN created, added correct VLAN tag, assigned to an interface, added a new route for our internal server subnet.
We can ping the SelfIP of both devices in HA and the floating IP address for that VLAN, but we cannot ping any virtual server IP addresses.
We can ping the nodes from the appliances and the health monitors return the nodes as healthy. Not using SNAT or automap. No ACL's, no connectivity profiles. We've stripping the Virtual Servers down as to basic as possible.
However, we're stuck as to why the VirtualIP addresses cannot be pinged.
Routing on our core router for that subnet is setup correctly, according to network engineer.
We're wondering if its a return path isssue? But we've run tcpdump and can't see any connections to the Virtual IP, but can see traffic to the self ip addresses.
Ideas where to look next? Thanks guys.
