Problem between F5 CGNAT and Graylog Server

Hi,

I didnt come across such a problem.

However, best way to troubleshoot to find the root cause is to take packet captures::

Here is the command you could use to get packet captures F5:

tcpdump -vvni 0.0:nnnp -s0 host <IP_Address_of_Graylog> and port <PORT_of_Graylog> -w /var/log/file_name.pcap

Hope this helps,

Nag
