Ubuntu server connection failed sometimes for different subnet client
I am using vmware 6.5
Machine-1 Ubuntu server 16.04
# The primary network interface dor virtaual Machine-1
auto ens192
iface ens192 inet static
address 172.16.3.133
netmask 255.255.0.0
gateway 172.16.3.1
dns-nameservers: 172.16.3.254 172.16.3.253
Machine-2 Ubuntu server 16.04
# The primary network interface dor virtaual Machine-2
auto ens192
iface ens192 inet static
address 172.16.3.134
netmask 255.255.0.0
gateway 172.16.3.1
dns-nameservers: 172.16.3.254 172.16.3.253
Machine-1 pinging Machine-2 always. There is no connection issue. (same subnet)
My client machine is windows 10 and my network information is like this:
IPv4 Address. . . . . . . . . . . : 172.16.161.80
Subnet Mask . . . . . . . . . . . : 255.255.252.0
Default Gateway . . . . . . . . . : 172.16.160.1
I can connect to Machine-1 using Putty. But my connection failed after several minutes. (Putty error: Network error software caused connection abort)
So I open Machine-2 using Vmware UI and pinging to Machine-1, then I can connect again from my Windows machine. I mean network interface looks as if it is sleeping for different subnets.
If any client has different subnet, this issue is occured. We can not solve this problem.

Check if you have any software in Windows 10 that "protects" your network connections like anti-virus or anti-malware as they have been known to interfere with VMWare.
But my connection failed after several minutes.
By default SSH will often close inactive connections unless you specify that they should be "keep alive"

We use Sophos protection. But as I specified, If Machine-1 or Machine-2 pings continuously to any machine in local network, the windows client machines connections does not abort.
