multiple dhcp ips on a single interface

I bought orange pi one and I mount ubuntu 18.04.

I and my friend setup as below.

but we can didn't ping.

ping -c 4 -I vir1 [login to view URL]

and we don't know it is right or fault.

so, can you fix our fault?


# Primary interface

auto eth0

iface eth0 inet dhcp

up ip link set dev eth0 promisc on

# Macvlan interfaces

auto vir1

iface vir1 inet dhcp

pre-up ip link add link eth0 address 02:cd:ab:00:10:01 vir1 type macvlan

post-down ip link delete vir1

auto vir2

iface vir2 inet dhcp

pre-up ip link add link eth0 address 02:cd:ab:00:10:02 vir2 type macvlan

post-down ip link delete vir2

pptpd setup

sudo apt-get install pptpd

local/remote ip

/etc/[login to view URL]

localip [login to view URL]








cbd pptpd 1234 [login to view URL]

cbd2 pptpd 1234 [login to view URL]


iptables -t nat -A POSTROUTING -s [login to view URL] -o vir1 -j MASQUERADE

iptables -t nat -A POSTROUTING -s [login to view URL] -o vir2 -j MASQUERADE

/etc/[login to view URL]

/sbin/iptables-restore < /etc/[login to view URL]

IP forwarding

/etc/[login to view URL]


sudo sysctl -p


/etc/ppp/[login to view URL]

ifconfig $1 mtu 1500

sudo chmod a+x /etc/ppp/[login to view URL]

sudo pptpd restart

And, my final goal is that use many ip throuth pptp.

When I receive same subnet ips. Does that also have no problem?
