Tracing traffic through an LTM.
How can I troubleshoot an LTM configuration where I see traffic proceeding from the backend of the LTM to the application node, and oberving the node responding by sending traffic back to the backend IP address of the LTM while not seeing the VIP of the application respond to the client?
Could I determine if the node is stomping on the automap SNAT and trying to send the traffic somewhere else ?
I have tcpdump-ed the backend to the node: tcpdump -ni vlan006 host 10.93.65.21 -s 0 -w ./be.cap
as well as the frontend to the VIP.
tcpdump -ni -frontend host 10.92.16.81 -s 0 -w ./fe.cap
The traces do in fact show what the application is observing but I don't know how to debugg it.
