Connection loss Client -> F5 BIGIP LTM

Hi

1)

Assuming that the  3 application servers (windows server 2003), which are behind the F5 BIGIP are in the same Physical location as of F5, Protocol Profile (Server) should be LAN optimised and not WAN optimised.

Depending on where Clients are, you should use appropriate Protocol Profile (Client) profile.

2)

Depending on how much load BigIPs currently are under, if you filter for packets of specific client experiencing issue, it will be safe.

You can use following command::

tcpdump -vvni 0.0:nnnp -s0 host <client_IP> -w /var/tmp/file_name.pcap

This will capture packets on both client and server side

Hope it Helps,
