I have the following problem. I cant ping 8.8.4.4

ping -I ens192 8.8.4.4

PING 8.8.4.4 (8.8.4.4) from 192.168.4.44 ens192: 56(84) bytes of data.
^C

ping -I ens192:1 8.8.4.4
ping: invalid source address ens192:1

My network consist of 1 Network interface and on second virtual on top of it. And two gateways for it. Both gateways need to be configuerd.

I checked befor and the google server is reachable with the normal gateway line in Debian. From both Gateways.
So how do i get it to work ?

My interface config file

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto ens192
allow-hotplug ens192
iface ens192 inet static
 address 192.168.4.44
 netmask 255.255.255.0
 post-up ip route add 192.168.4.0/24 dev ens192 src 192.168.4.44 table rt1
 post-up ip route add default via 192.168.4.1 dev ens192 table rt1
 post-up ip rule add from 192.168.4.44/32 table rt1
 post-up ip rule add to 192.168.4.44/32 table rt1

auto ens192:1
allow-hotplug ens192:1
iface ens192:1 inet static
 address 192.168.4.201
 netmask 255.255.255.0
 post-up ip route add 192.168.4.0/24 dev ens192:1 src 192.168.4.201 table rt2
 post-up ip route add default via 192.168.4.3 dev ens192 table rt2
 post-up ip rule add from 192.168.4.201/32 table rt2
 post-up ip rule add to 192.168.4.201/32 table rt2

A couple of things:

• Pass the IP address of the interface on -I. I.e. -I 192.168.4.201
  


• The default route on the second interface says dev ens192 instead of dev ens192:1
  


• I guess that you either can't ping 192.168.4.1 and 192.168.4.3 or there is some additional configuration that's not shown here.
