An LTM device has a virtual server configured as a Performance Layer 4 virtual listening on 0.0.0.0:0 to
perform routing of packets to an upstream router. The client machine at IP address 192.168.0.4 is
attempting to contact a host upstream of the LTM device on IP address 10.0.0.99.
The network flow is asymmetrical, and the following TCP capture displays:
# tcpdump -nnni 0.0 ‘host 192.168.0.4 and host 10.0.0.99’
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on 0.0, link-type EN10MB (Ethernet), capture size 96 bytes
