Traceroute % Loss

When I perform a trace route to a host behind the firewall (FortiGate 601E)

- i see a 75 % loss at hop 19 which is the external port of the firewall . Should I be concerned about this ?

19.|-- 203.126.222.xxx 75.0% 4 260.6 260.6 260.6 260.6 0.0

20.|-- 203.126.222.yyy 0.0% 4 259.1 262.1 259.1 267.2 3.6

However, if I traceroute only up to the firewall external port, I see 0% loss.

17.|-- 203.126.222.xxx 0.0% 4 263.5 262.5 262.0 263.5 0.7
