Hi Anton,Hi everyone,
I'm not at all confident that I understand what's going on here with the various routers.
I own an Asus AC-3200. Is RMerlin's 384.6 (or stock 3.0.0.4.382.50624) likely the end of the line for firmware updates for this router?
Thanks,
Anton

Hi all,
Just a quick and hopefully simple question from me.
I'm at work and want to upgrade to 384.7 remotely and my question is, will I have to change anything with regards to my DDNS address that I use to access the router after it reboots itself?
RMerlin: unless uPnP is considered low priority, I hope you can take a look at the issue or suggest some troubleshooting steps so that we can at least get the idea why uPnP suddenly stopped working since 384.6.
I should admit that I'm in double-NAT. There's only an Asus router behind the ISP router-modem. ISP modem has uPnP enabled since the beginning (3 years ago), and the Asus router has been usually set as DMZ host.Working normally for me. Are you in a dual NAT setup? Any customization done to your firewall configuration?
Nat behind Nat is ok....firewall behind firewall not so much. I would use the firewall on the Asus router.What else would you think I may test: try disabling the firewalls on (both) ISP modem and/or the Asus router for a while?
Ideal setup would be your Asus in the DMZ of your ISP modem, better is to bridge the modem.Nat behind Nat is ok....firewall behind firewall not so much. I would use the firewall on the Asus router.

kernel: nf_conntrack: automatic helper assignment is deprecated and it will be removed soon. Use the iptables CT target to attach helpers instead.
I seem to have this same issue. DOCSIS modem. After rebooting my RT-AC3100 the internet is out. I have to manually reset the entire network to regain connectivity.
Check that your DNS resolvers can do DNSSEC. If you enable DNSSEC and the DNS servers do not fully support DNSSEC, when you reboot the router the NTP Server URL will not be resolved and the router can't set its time (has no internal clock) and even though the router gets an IP address from the WAN DHCP it will not allow a connection. Quad9 (9.9.9.9 and 149.112.112.112) does work with strict enabled. Clean Browsing should work, too. You might be able to use an IP instead of a URL in the Time Server setting.)
Solution
DNSSEC: strict unsigned validation - Changed back to "No" - fixes the issue.
I performed a factory reset, and reconfigured from the ground up manually.Same setup here. AC-87U went from .5 t o .7. Issue arose when connectivity actually failed. Router page reports internet status disconnected although it's actually working just fine (typing this message) after reboot of router.
I get this on Network Analysis: ping: bad address 'www.facebook.com'
Looks like the router itself is not resolving addresses properly whilst connected HW does ?!

I searched the SNB forums and found the same question asked 10 times and never a reply. Anyone know what and why?
Secure use of Connection Tracking Helpers

..."Following the preceding remarks, it appears that it is necessary to not blindly use helpers. You must take into account the topology of your network when setting parameters linked to a helper."

"...However, it is a boolean value and something has to go there on boot, and the kernel has no way to remember what its state was when (and if) it was last booted. So, it picked 1."
Ok. But unless CentOS patches their kernels in this regard, it will eventually get there as well. This is a mainline kernel change, so it should reach everywhere eventually. Some distros might have better defaults, but Ubuntu 12.04 didn't at least.
Really, on an AC86U? Here is uname output (Cloudflare thinks I'm trying to spam the forums)so essentially, in a nutshell, we have an old kernel
