ER8411 v1.0 Firmware 1.3.6 issues
Hello,
I had my ER8411 v1.0 on 1.2.3 Firmware for a long while. I decided to upgrade today to the latest (1.3.6) and since the update i have connectivity issues. On my mac and iphone AppStore login, iCloud login, PeperLess vToken app are not connecting and giving me a timeout. I did a full restart, not helped, no issues in the logs of my OC200. This issue was not a problem on 1.2.3. If i connect my mac to a hotspot it works, i connected it directly to the ISP router all fine. Any advice? can i downgrade back to 1.2.3 even if it says its ireversable?

@cykz some systems, especially Windows, do ignore DHCP option 26, resp. do not ask for DHCP option 26 - so for testing purposes you may set the MTU via CMD with admin rights for a Windows machine
netsh interface ipv4 set subinterface “Your-LAN-Connection" mtu=1492 store=persistent

I had a similar issue, I disabled DNS under IDS/IPS and everything went back to normal.

Well I will RMA the device now. Its 20 months old, and Just now i've been using the PPPoE feature figuring its broken. You can't tell me having to configure MTU on endpoints is a desired feature.

Same here. Some pages - depending on the browser load really slow and in fragments - while other connections (e.g., confirming AppleIP on the iPhone, or some Smart Home Apps (Miele)(iPhone)) don't work at all. Error message from all Apps: "no internet connection".
On the Pages which load slowly, I can see a persisting TLS handshake status message in the footer line of the browser (Firefox) with pages then loading bit by bit. Same pages in MS Explorer load endlessly, much longer than in Firefox.
No problems with a VPN Service turned on.
No issues with 1.2.x versions.

Dear All,
Is there already an official solution available/in sight?
I did a few tests and for me the workaround "disable DPI" seems to work - but that could not be the final way to go?
My configuration and tests:
2 sites (A & B), software-controller on site A
Both sites almost identical setup: Internet - ER8411 - OPNSense as transparent bridge - OMADA switches and clients
Both sites connected via PPoE (DE: 1&1 (site B) and vodafone (site A))
Test pages/Apps: www-dot-commerzbanking-dot-de: took almost 2 mins to be fully operational; Miele-Smarthome: did not load at all, terminated with "Not connected to the internet", Update pages OPNSense: took over 30 mins to show updates but failing to download files and to update
- First step: "rebooting" of both sites => did not help
- Disabling DPI - site A => did not help
- Changing controller SW to 6.1.0.10 => did not help
- Disabling DPI & restart of ER8411 site A => helped
- Disabling DPI & restart of ER8411 site B => helped partially (commerzbanking works, rest not)
I am now OK with site A but still working on site B.
Both sites worked fine without any problems before the 1.3x update. Thnik the update to controller version from 5 to 6 was without any impact.

The alert "ARP conflict detected" indicates that there are two clients with the same IP address in the topology. Please check for any IP address conflicts.
