Re: ER605 ER7206 v1 - DHCP Server May Fail With 1.2.0 and 1.2.1 Firmware [Updated on Jan 30th 2023]

I don't know if this is related but most of the reserved addresses that I entered using Firewall/Anti ARP Spoofing page do not appear in the reserved addresses of the LAN pages. Furthermore, if I try to update in the LAN Reserved page, nothing happens AND if I try to click "Disable" on the list of addresses it says "Invalid MAC or IP address".

On your Firewall / IP-MAC Binding page, have you clicked the icon "Export to DHCP Address Reservation" below to make the address appear in the LAN / Address Reservation page?

Do you still have devices that are getting duplicate IP addresses since your last reboot? If yes, what are those devices?

Dear @Supadone,

Unfortunately, the issue still exists for me. After the upgrade to the beta I restarted the ER7206, but some devices didn't get an IP address assigned... Back to 1.2.1 at least that works again.

 

To better assist you, I've created a support ticket via your registered email address, and escalated it to our support engineer to look into the issue. The ticket ID is TKID230203174, please check your email box and ensure the support email is well received. Thanks!

Dears, good morning!

I have an ER7206 model with the beta bios version available (1.2.3 Build 20230118 Rel.42096) and the problem persists. The devices do not get IP automatically by the DHCP server enabled on the equipment. I can only browse if I enter an IP reservation for the workstation, without this reservation the device simply does not get the IP.

Before beta update, the devices didn't get any IP information from DHCP, after the update the devices get only gateway and primary DNS.

I need a solution to this problem as soon as possible because I have part of a client's operation stopped.

I still cannot use mDNS on gateway. Option is greyed out. Is that normal? Can you confirm mDNS will be activated on ER605v1 in a future update?

 

Yes, mDNS will be supported on ER605v1 in the subsequent update.

 

  @Fae Hello. will there be Steful ACL as well for ER-605 v1? I have 8 deployed to multiple clients, and the mDNS and Stateful ACL will be a great feature addition to these OG routers :)

I would expect Stateful ACL will be supported as well.

@ioannis_compet

I have the same issue when I run the AI WLAN optimization feature. (reproducible)

 

You can try to force provision your router to see if that fixes your problem.

OmadaLinux v5.13.10 R605 V1:1.3.0 - Build 20230511 R.51317 SG2008P V1:V1.0.8 Build 20230602 R.73473 SG2008P V3:V3.0.5 Build 20230602 R.73473 3 x EAP245 V3:V5.1.0-Build 20230104 R.79433

  @Fae yes that is the only way I can get the reserved addresses with the descriptions. Device descriptions cannot be entered in the Network/ LAN reservation dialog.

 

There is no correlation to the duplicate addresses. Sometimes it's a fire TV device, sometimes an Alexa device or smartphone or watch.
