Hello,
I would suggest to not use the flag all in the flow traceoptions. This logs a lot of background noise.
Use the traceoptions flag basic-datapath. Additionally, also setup the filter for anything destined to 10.10.3.29 as well.
set security flow traceoptions file alg_deny files 2 size 1m world-readable
set security flow traceoptions flag basic-datapath
set security flow traceoptions packet-filter packet_filter1 source-prefix 10.10.3.29
set security flow traceoptions packet-filter packet_filter2 destination-prefix 10.10.3.29
Regards,
Vikas
