Whether such routing through 2 network interface cards is possible?

Question

Computer networks

Good evening, dear connoisseurs!
Attention, question!
There are 2 computers of wines 10:
1) 192.168.10.10/24; -1 network card
192.168.20.10/24 - 2 network cards
2) 192.168.20.20/24
SQL server is installed on host #1 and machines from *.10.0/24 access it perfectly, it is necessary that they see it from the network *.20.0/24 10th subnet.
Tried on host #2 gateway 192.168.20.10
tried also on host #2 route add 192.168.10.0 mask 255.255.255.0 192.168.20.10.
Where to dig and is it possible at all?

Answer 1

There is no need for routing. Judging by the description 192.168.20.20/24 directly connected both on the first and on the second machine.
A firewall may be an obstacle to the passage of traffic. Check your firewall settings.

Answer 2

For Windows, the RRAS service is needed, it is present only in server OSes.

Answer 3

Only4You , yes, allow several sql addresses and that's it

Answer 4

How many machines are on the 192.168.20.0/24 network?
If there is only one - why such difficulties?
On the first machine, combine both setevukha into a bridge and give the second machine an IP from the range 192.168.10.0/24
As for access to SQL, most likely the firewall does not let it.
Check that port 1433 is in the exceptions
On the host, I understand Win10? How does he identify networks? (enterprise or public network)
