Sonic should not be blocking ICMP traffic towards any customer addresses (except for brief periods during DDoS mitigation). The traceroute in the superuser post shows traffic dying before (or right after) leaving the private IP space on the connection (10.x.x.x/8). That looks to be VPN/far end behavior and unrelated to Sonic's network. There are circumstances where some of the Sonic routers along the path won't respond in the traceroute, but they just show up as "* * *"s in the path.
Please provide some specifics and traceroutes if this still appears to be an issue.
My traceroute to scubbo appears normal, although the attached device itself does not appear to be responding with TTL exceeded (acceptable residential gateway behavior). Below that, you'll see a successful ping to the WAN address.
