We do similar and are not seeing any issues on 13.2.
When our SMs are in NAT mode, they get the DNS servers from their DHCP
server, and propagate the DNS server addresses to their clients. I have
not seen one instance of this not working; and we have quite a few on
13.2 now.
Likewise, we also upgraded the SMs first, then the APs. Works as
advertised.

It’s a choice you make, do you want the SM to hand its own address out
via DHCP and act as the DNS server, or do you want the SM to hand out
your DNS server IP addresses via DHCP? We do the latter, and manually
enter those DNS server addresses into the SM. Most of our residential
customers have their own WiFi router behind the SM, this way it gets
handed our DNS server addresses and probably acts as a DNS proxy itself.
But that is just our preferred way of setting it up. I don’t believe
any of this has changed since many FW versions ago on PMP100.
The reason I asked was, if you are disabling DNS proxy on the SM, then
you are using the same configuration we are and I am surprised that
13.2 broke it for you. If you are enabling DNS proxy, I don’t think
we do that anywhere, so I would be unaware if 13.2 broke it.

It’s set to the default upon flashing, which appears to be disabled.
TBH if it is something that should be enabled, then it should have
been by default with the release IMHO.

You have DNS Server Proxy enabled or disabled on the SM?

*Subject:*[AFMUG] Cambium 450 13.2 issues
We’ve seen a few issues with the new 13.2 firmware for the 5.4/5.7 450
equipment. Here is the bucket list –
·If an AP is on 13.2, but an SM is on 13.1.3, there is the possibility
that the SM cannot update because it is stuck in 8x/1x mode and
throughput is significantly decreased. Manually going to the customer
site and updating can bring the radio back up
·In some cases, SM’s after the update come back online with a better
signal but a decreased throughput and modulation rate than what was
previously viewed on 13.1.3
·Behind a NAT’d SM, it does not appear that DNS is being properly
passed by the SM to a customer’s router. Manually setting the
customers router to our DNS servers (instead of relying on the NAT’d
IP address) appears to resolve the issue. Manually setting the DNS IP
address to the NAT’d SM’s IP does not resolve the issue.
We have since rolled back from 13.2 to 13.1.3 which was stable with
our particular network configuration. I have no intention of rolling
forward to 13.2 again for Cambium testing purposes (sorry guys)
however I would be able to answer any specific details to our
configuration if it is helpful.
