Pfsense shows twice in traceroute
traceroute to dallas.testmy.net (18.104.22.168), 30 hops max, 60 byte packets

why does pfsense show up twice?
Are you behind a double nat? Just because it resolves to pfsense does not mean it actually is pfsense.
What is the IP address pfsense WAN interface?
The wan interface is my public ip address. I have not configured any nat at all
Packet capture on your WAN filtering on that 75. IP and do it again, then stop the capture. I suspect your next hop router responds with source IP 192.168.1.1 on its TTL expired in transit messages. The response time shows it's likely coming from your upstream gateway.
