How to configure pppoe with macvlan interface? #181

onlymash · 2020-11-14T02:43:46Z

There are only macvlan-dhcp and macvlan-static in the examples, but macvlan-pppoe does not exist. I want to implement pppoe and dhcp for a single WAN interface.
I know this is possible in openwrt, now my router runs archlinux.

If it is possible in OpenWRT, then I would like to think it is within the scope of netctl :-).
Let's see whether it is already possible. If not, we need to find out how to do it manually and then implement it in netctl.

I am not entirely sure what you want. Would something like the following achieve what you are after?

/etc/netctl/MyPPP

Description='My PPPoE connection'
BindsToInterfaces=eth0
Interface=ppp1
Connection=ppp
User='example@yourprovider.com'
Password='very secret'

# etc.

/etc/netctl/MyMacVLAN

Description='Virtual LAN on the MyPPP connection'
BindsToInterfaces=ppp1
After=(MyPPP)
Interface=mac0
Connection=macvlan

# etc.

My configuration process is as follows.
Although the wan0.2 interface was created, if not specify the IP, the running state is failed

$ cat wan0.1
Description='Virtual LAN with random MAC address on interface wan0'
Interface=wan0.1
Connection=macvlan
BindsToInterfaces=wan0
Mode="bridge"
IP=static
Address="192.168.200.2/24"
Gateway="192.168.200.1"
DNS=("192.168.200.1")

$ cat wan0.2
Description='Virtual LAN with random MAC address on interface wan0'
Interface=wan0.2
After=(wan0.1)
Connection=macvlan
BindsToInterfaces=wan0
Mode="bridge"

$ cat pppoe 
Description='wan0.2 PPPoE connection'
Interface=wan0.2
After=(wan0.2)
Connection=pppoe
User='username'
Password='password'
...

$ sudo netctl start wan0.1
$ sudo netctl start wan0.2
$ sudo netctl start pppoe

$ netctl status wan0.2

Ah, so you want to run PPPoE inside the macvlan. How about this?

/etc/netctl/MyMACVLAN

Description='Virtual LAN for the MyPPP connection'
BindsToInterfaces=eth0
Interface=mac0
Connection=macvlan
Mode=bridge
IP=no

/etc/netctl/MyPPP

Description='My PPPoE connection'
After=(MyMACVLAN)
Interface=mac0
Connection=pppoe
User='example@yourprovider.com'
Password='very secret'

# etc.

After I add IP=no to wan0.2 and reboot the system, pppoe will fail

$ netctl status pppoe

wan0.2 interface is in the up state, pppoe stops the next action

joukewitteveen · 2020-11-18T21:32:23Z

Makes sense, I guess this is a situation where it is okay to add ForceConnect=yes to /etc/netctl/MyPPP.

Thanks, it solved my problem perfectly
