I bought a new wired network card whose chipset is intel 82576,it is time to set my old pc as a formal router now.
My home network diagram：
internet --> optical modem --> in : network card built in mother board (pc1)
--> out : new bought wired network card ----> an other pc (pc2) connected with it via cale
Show configuration file in pc1:
cat /etc/config/network
config interface 'loopback'
option ifname 'lo'
option proto 'static'
option ipaddr '127.0.0.1'
option netmask '255.0.0.0'
config globals 'globals'
option ula_prefix 'fde9:d92f:dfe0::/48'
config interface 'lan'
option type 'bridge'
option ifname 'eth0'
option proto 'static'
option ipaddr '192.168.12.1'
option netmask '255.255.255.0'
option ip6assign '60'
config interface 'wan'
option ifname 'eth0.2'
option _orig_ifname 'eth0.2'
option _orig_bridge 'false'
option proto 'pppoe'
option username 'xxxx'
option password 'xxxx'
option ipv6 'auto'
option keepalive '0'
Why can't ssh pc1 from pc2 with ssh ?
ssh root@192.168.12.1
Show ip addr in pc2:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host

Is the new wired network card be activated?
I show the network setting in my pc2 :
cat /etc/network/interfaces
source /etc/network/interfaces.d/*
auto lo
iface lo inet loopback
auto dsl-provider
iface dsl-provider inet ppp
pre-up /bin/ip link set enp6s0 up # line maintained by pppoeconf
provider dsl-provider
auto enp6s0
iface enp6s0 inet manual
