Routing RTNETLINK answers: No such process

Hello,

I have a opensuse Linux server with two nics.
eth0 = internal network with 172.16.1.24
eth1 = external network with ip 172.19.3.2

Internal networks: 172.16.0.0/16, 172.17.0.0/16 and 192.168.0.0/16.
External network: 172.19.3.0/16

The default gateway is 172.19.3.1 on eth1.

IP Forwarding is disable. Only a Proxy Server on this server ist running, so only local access to the external network is required. But all hosts in the several local subnets must reach the server.

My problem is, that the internally networks 172.17.0.0/16 and 192.168.0.0/16 on eth0 I can't reach.

Only the 172.16.0.0/16 network is reachable.

Code:
ip route add 172.17.0.0/16 via 172.16.0.1 dev eth0
RTNETLINK answers: No such process
 
ip route add 192.168.200.0/16 via 172.16.0.1 dev eth0
RTNETLINK answers: No such process

eth0
Code:
BOOTPROTO='static'
BROADCAST=''
ETHTOOL_OPTIONS=''
IPADDR='172.16.1.24/16'
MTU='1500'
NAME='82566DM-2 Gigabit Network Connection'
NETWORK=''
REMOTE_IPADDR=''
STARTMODE='auto'
USERCONTROL='no'
PREFIXLEN='16'

eth1
Code:
BOOTPROTO='static'
BROADCAST=''
ETHTOOL_OPTIONS=''
IPADDR='172.19.3.2/24'
MTU='1500'
NAME='LNE100TX'
NETWORK=''
REMOTE_IPADDR=''
STARTMODE='auto'
USERCONTROL='no'
PREFIXLEN='24'

Please give me hint.

Thank you.

Felix

VLAN-INTERFACES(5)						   File formats 						VLAN-INTERFACES(5)

NAME
/etc/network/interfaces (vlan) - vlan extensions for the interfaces(5) file format DESCRIPTION
/etc/network/interfaces contains network interface configuration information for the ifup(8) and ifdown(8) commands. This manpage describes the vlan extensions to the standard interfaces(5) file format. Primary extensions exist to make and destroy vlan interfaces, secondary extensions exist for ipv4 interface manipulation which are gener- ally needed when using (a lot of) vlans. VLAN CREATION
Vlan interface definitions exist of the vlan interface name, and an optional 'raw-device' parameter. Vlan interfaces are numbered 1 to 4095. You have the option to have interface names zero-padded to 4 numbers, or just the plain digits without leading zero. The following example shows four ways to create a vlan with id 1 on interface eth0. They all result in different names. iface eth0.1 inet static address 192.168.1.1 netmask 255.255.255.0 iface vlan1 inet static vlan-raw-device eth0 address 192.168.1.1 netmask 255.255.255.0 iface eth0.0001 inet static address 192.168.1.1 netmask 255.255.255.0 iface vlan0001 inet static vlan-raw-device eth0 address 192.168.1.1 netmask 255.255.255.0 # We don't have br support out of the box iface br0.2 inet static vlan-raw-device br0 address 192.168.1.1 netmask 255.255.255.0 # Aliases are ignored iface br0.2:1 inet static address 192.168.1.1 netmask 255.255.255.255 EXTRA IFACE OPTIONS
Usually someone who uses vlans also wants to do some other manipulations with the ip stack or interface. vlan-raw-device devicename Indicates the device to create the vlan on. This is ignored when the devicename is part of the vlan interface name. ip-proxy-arp 0|1 Turn proxy-arp off or on for this specific interface. This also works on plain ethernet like devices. ip-rp-filter 0|1|2 Set the return path filter for this specific interface. This also works on plain ethernet like devices. hw-mac-address mac-address This sets the mac address of the interface before bringing it up. This works on any device that allows setting the hardware address with the ip command. AUTHOR
