If I run a traceroute from a client on my internal network to any Internet address, the first hop after my Opnsense box is always * * * then I get a normal result i.e. a bunch of addresses inside my ISP then on to the destination.
My question is can I do anything about this? Is it some setting I have 'wrong' in Opnsense or could it be the cable modem that's connected to my ISP that's the issue?
Here's an example:
$ traceroute 8.8.8.8
traceroute to 8.8.8.8 (8.8.8.8), 64 hops max, 52 byte packets

The next hop is the gateway for your opnsense machine so probably it does not respond to pings. Im assuming that the gw on your opnsense box is your ISP. If its your own equipment then you can enable pinging.
