#9273 closed defect (worksforme)

No internet access on PC with cloned MAC address

Reported by: vargalex@… Owned by: developers
Priority: high Milestone: Barrier Breaker 14.07
Component: base system Version: Trunk
Keywords: MAC clone Cc:



I have a TP-Link TL-WR1043ND router with latest OpenWrt trunk installed. I have a DHCP WAN connection, but I need to clone my MAC address from my PC (my PC MAC address is registered by ISP).
After that, on the router and on other machines all works perfect, but my PC have no internet access. LAN works. When I change the MAC address of my PC, than all OK.
With stock firmware and DD-Wrt MAC cloning works without problem.

So the switch does not cope with the same mac on different ports while it handles it okay with dd-wrt or stock?

Yes, this is the situation. You can read about this here too:

I don't know that this type-specific, or global error.

I wrote wrong information (now I tested all the firmwares):

  1. With stock firmware works perfect the MAC clone
  2. With OpenWrt I have no internet access on PC with the same MAC Address
  3. With DD-Wrt I have no internet access on PC with the same MAC Address.

I can confirm this.

On the router, please try this:

swconfig dev eth0 set enable_learning 0

You can make it permanent by adding this to your "config switch eth0" section in /etc/config/network:

option enable_learning 0

I already fixed it by changing mac address on PC! :P But I will try your fix to see if it works.
