I have a peculiar problem as described below.
Two sites with a linux (Raspbian Jessie Lite) based routers each having network as stated below
Site1
Raspberry Pi Router 1
eth0 192.168.1.101/24
eth1 192.168.230.1/24
Computer1 connected to above router with address 192.168.230.103 Gateway is 192.168.230.1
Site2
Raspberry Pi Router 2
eth0 192.168.1.102/24
eth1 192.168.231.1/24
Computer2 connected to above router with address 192.168.231.103 Gateway is 192.168.231.1
Router 1 configuration
/etc/iproute2/rt_tables on Router 1
.
.
.
1 eth0
2 eth1
/etc/network/interfaces file on Router 1
source-directory /etc/network/interfaces.d
auto lo
iface lo inet loopback
allow-hotplug eth0
auto eth0
iface eth0 inet static
hwaddress ether b8:27:eb:89:27:4f
address 192.168.1.101
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
up ip route add 192.168.1.0/24 dev eth0 table eth0
up ip route add default via 192.168.1.101 dev eth0 table eth0
up ip rule add from 192.168.1.101/32 table eth0
up ip rule add to 192.168.1.101/32 table eth0
allow-hotplug eth1
auto eth1
iface eth1 inet static
hwaddress 00:e0:4c:53:44:58
address 192.168.230.1
netmask 255.255.255.0
network 192.168.230.0
broadcast 192.168.230.255
up ip route add 192.168.230.0/24 dev eth1 table eth1
up ip rule add from 192.168.230.1/32 table eth1
up ip rule add to 192.168.230.1/32 table eth1
I also applied IP Forwarding through following commands as a root user echo 1 > /proc/sys/net/ipv4/ip_forward Also, in the /etc/sysctl.conf file , I set net.ipv4.conf.all.forwading=1
Configuration for Router 2 is exactly same with appropriate addresses set. In effect, the setup is
Computer1<------>Raspberry router1<------->Raspberry Router2<------> Computer2 Configuration is a simple lab setup without internet and NAT Problem From Computer 1, I can ping router 1 interfaces 192.168.230.1 (No problem) and 192.168.1.101 and I can ping Router 2 interface 192.168.1.102. But I cant ping the LAN side interface of Router 2 that is 192.168.231.1 and obviously, I cant ping computer 2 at 192.168.230.103. Same problem occurs from Computer 2. Both Computers run Ubuntu 16.04 LTS.
I alternatively also tried adding routes on each router (Route of Router 1 specified below)
route ip add -net 192.168.1.0 netmask 255.255.255.0 eth0
route ip add -net 192.168.230.0 netmask 255.255.255.0 eth1
route ip add -net 192.168.231.0 netmask 255.255.255.0 eth0
However, the result is the same. Can anyone give me working configuration for the same.
Thanks and regards in advance
