Hi ajay_kumar,
Can you enable packet tracing :
set security flow traceoptions file DebugTraffic
set security flow traceoptions flag basic-datapath
set security flow traceoptions packet-filter MatchTraffic source-prefix 192.168.41.1/32 destination-prefix 192.168.5.102/32
Then can you try pinging using this command :
>ping interface reth1.0 192.168.5.102
And provide us with the output from the log file DebugTraffic ?
