[RndTbl] Problems with setting up off-site backup via Shaw (residential)

[Kevin McGregor]

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:

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?
