pls share your /etc/network/interfaces

i am at my wits end. i have searched high and low for a configuration for 2 physical ethernet adapters with softether. here's my config:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp
hostname vpnserver

auto eth1
iface eth1 inet manual
up ifconfig $IFACE 0.0.0.0 up
down ifconfig $IFACE 0.0.0.0 down

softether runs on a hyper-v vm with 2 virtual network adapters plugged into the same virtual switch. eth1 allows mac spoofing, with vlan set to trunk and 0,1-1000.

eth0 doesn't allow mac spoofing. vlan is set to access with a vlanid.

i have a pfsense vm running on the same virtual switch (vlan trunk, 0,1-1000). it serves as a dhcp server.

now i bind my hub to eth1. user cannot connect because there is no dhcp server connection.

i can see that eth1 is not working as expected. what's the correct config?

Did you try packet capture?
