I've been trying to set up off-site backups from my home (site A) to another person's home (site B).
My home internet (i.e. site A) is provided by Shaw. Site B has internet services provided by Telus, which is provided by Altima Telecom... which is provided by Shaw (as near as I can tell).
Both sites have a server running TrueNAS. In the past I had this setup working, although the internet providers were different at the time. It involved forwarding a port by the router at site B to the destination server within site B. I haven't been able to get this to work since the change in providers. The destination simply doesn't respond no matter what port-forwarding settings I use.
I ran a traceroute from site B to google.ca: Tracing route to www.google.ca [142.251.211.227] over a maximum of 30 hops:

Trace complete.
From site A to site B, the traceroute shows:

Can anyone explain what I'm seeing here? E.g. Why does the site B IP address appear twice? Why all the following request timeouts? I've used the WAN IP address of site B as the destination and set up port forwarding from that router to my remote NAS box, but as I said there is never any response.
Does anyone have any suggestions as to what to try next?
