Bug Description
When VM1 does a traceroute to VM2, I see that the first set of 3 UDP packets with TTL = 1 is being answered by vRouter with its own IP address instead of GW IP Address.
VM2 = 40.40.40.3
VM1 = 30.30.30.3

Please see below:

3 40.40.40.3 (40.40.40.3) 5.406 ms 8.606 ms 8.576 ms
Please note, this is a service chain scenario and both VMs and vSRX are on the same compute.
I think for a customer VM, the underlay should not be visible and hence the VM should not see the IP-Fabric details.
Please fix it such that vRouter responds back with GW IP instead of its own IP.
Greetings,
Sandeep.
