I met the same prolem with vyos 1.2.0. EPA2

Sorry, It's my cable was broken.

No ISP problems. Vyos always has the problem that when i install a new vyos on a server with a intel network adapter which has 4 ports. Every time i need to change the mac address of each network interface. I'm sure it's a bug that got the wrong mac address of each interface(eth0-eth4, not pppope interface).

Dear, Hagbard
Seem like that i found the problem that mac address of each interfaces had been switched randomly after upgrade rc7 to rc8.

Sorry. When i upgrade rc7 to rc9 is okay. but when i reboot to rc8 and then reboot to rc9. it failed again.

@dongjunbo Perfect. So it looks like that you have a valid ppp session established (session id 0x5d58). Does 'sudo ip sh a' show you a ppp0 interface or something similar? I tested the ppp client shipped in rc7 and rc8 and it appears it works as expected, so we need to find out what's going wrong on your side.

If you want to me run the command on rc8, I need to do it on Monday. Because When i reboot it. my lan connect to vyos will be lost.

Sorry for late responding.
I run the command on vyos 1.2 rc7 :
Here are the output:

@hagbard it's not really about server, but about client
wondering if we may need ppp for client part
