Hello T0nyP , No need to identify your gateway when performing traceroute , F5 does this path trace according to Routing table. > you can force your F5 appliance to check the path by using "traceroute -s " as you did.
> I checked this option in F5 bash and it doesn’t work as you said , but there is no need to identify the gateway or next hop , F5 uses ( the gateway or next hop from the "forced source ip " subnet that you identified in your command ".
> I want to say even if you specified the gateway , and overwrite the one which specified in f5 routing table/next hop , it is a wrong practise to use and it shouldn’t work.
> this is my explanation according to what I understood. Kindly clarify more , I will follow up with you. Regards
