CirrusTCP monitor on two nodes fail erratically
Good day,
We have a setup of consisting of four LTM's, two for external clients in a dmz, two for internal clients on the local network.
Only the internal devices are in a HA group.

CirrusHi,
The best way to investigate this issue is creating tcpdumps on both external and internal F5 devices. When it fails, do you see the external F5 send an ICMP? If so, does the internal F5 receives the ICMP? Create a file you can import in Wireshark.
Are there any other devices between external and internal F5? Firewall or router? Can you see something there?
With these kind of issues tcpdump and Wireshark are the tools to use.
Good luck.
Martijn.
