Routing Question

You attempt to ping a machine at IP 10.1.0.11 and get nothing back.
Your host ip is: 192.168.1.110 with on a /24 subnet
The router has two interfaces 192.168.1.1/24 (eth0) and 10.1.0.1/24 (eth1)
The remote machine has two interfaces 10.1.0.11/24 (eth0) and 10.2.0.11/24 (eth1)
The routing table for the remote machine is:
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 10.2.0.1 0.0.0.0 UG 0 0 0 eth0
10.1.0.0 0.0.0.0 255.255.255.0 U 1000 0 0 eth1
What might be the problem and why?
How could you correct it by only modifying the remote machine?

Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 10.2.0.1 0.0.0.0 UG 0 0 0 eth0
10.1.0.0 0.0.0.0 255.255.255.0 U 1000 0 0 eth1

What might be the problem and why?

To reach the 192.168.1/24 subnet, the routing table should have the routers reachable IP as the default route (0.0.0.0) but instead it has 10.2.0.1 which is not an interface on the router.

How could you correct it by only modifying the remote machine?
On the remote machines routing table, change the default gateway (0.0.0.0) route (currently set as 10.2.0.1) to 10.1.0.1/24

Its a static route issue:
0.0.0.0 10.2.0.1 0.0.0.0 UG 0 0 0 eth0
10.1.0.0 0.0.0.0 255.255.255.0 U 1000 0 0 eth1
network 10.1.0.0 should be route to eth0

The interface eth1 with IP 10.1.0.1/24 is down that's why connection not possible.

First check the running Routing Protocol configuration on router or static rouring entries, then check the System firewall and route print/ route add
