I actually noticed this happen on earlier releases of UTM 9. I am now running the latest standard release. After noticing the UTM no longer shows up on traceroutes, I tried several combinations of settings on the Firewall->ICMP settings but no change. Am I missing something here? Under traceroute settings I have enabled "Gateway is Traceroute visible" but not the forward traceroute option. Other enabled options include "Allow ICMP on gateway," "Gateway is ping visible," "Ping from gateway"
