How to add a static route to the other subnet?

Hello dear techies. There is a problem.
Router is D-Link DPN-R5402. The fiber connection. Firmware from Rostelecom with only one working LAN port. For a long time all worked on the Wi-Fi and LAN-1 was a piece of hardware with static IPS.
Now need to connect many wires. Stuck in LAN-1 router Asus RT-N12 C1 and got the following:
Dlink subnet:
Piece of hardware (was previously):
The ASUS subnet:

The actual problem is that needs to be done to the glands connected to the ASUS so she got the address from Dlink and talked with him as though connected directly. If someone will be, here is a screen of how static routes are in the admin panel of the ASUS

And a little bit of input:
the external IP of the ASUS (which is issued Glinka on Mac):
the current UI of the glands in the subnet of the ASUS:

With the ASUS it will not work, the device working in the network of ASUS ( can have an address from the network Dlink and surf the Internet or to other networks, if the ASUS is configured as a router. If the ASUS can work in bridge mode, then your problem will be solved, the ASUS is not their subnet, and all devices connected to the ASUS will be online Glinka ( If the ASUS there is no possibility of switching modes of the bridge/router, then the ASUS should disable the DHCP server and the cable from Dlink stick not in WAN port and LAN and then it will work as a switch that is identical to the operation of the bridge in your case, but you lose 1 port (WAN).
thank you. I had not thought of that to do. Now I play around - matilda.Schowalter commented on June 7th 19 at 15:41
Thank you very much. I have something really stupid. I wanted to get the undiminished functionality of the router ASUS, tormented with the settings. Bridge mode really is and it completely solves my current problem. Though in this case I lose many opportunities for detailed configuring of the router, Yes figs with him. - matilda.Schowalter commented on June 7th 19 at 15:44
Many providers allow users to change the settings on your router, call Rostelecom and ask them to configure Dlink as a bridge, and your ASUS will work as a router or do pokapatsya in the settings Glinka in search of the right functionality. It would be better if the ASUS has the desired functionality, and Glinka no. - Jaime_Brakus22 commented on June 7th 19 at 15:47

Default, usually, nothing to do, the traffic inside the network is allowed fully, that is, the network portion of the router works like a switch.

You place devices in a network. To disable Dlink or the ASUS DHCP server, even if it deals with one person.
What settings for switch no - cinemarena nonsense, "repeater" (repeater) completely different in case of wired network the so-called "hub" (i.e. a "dumb switch" which sends packets not in the right port and all) (Yes ,there are some repeaters - extenders, but this is different)
I think you didn't clear the problem. I had to add the switch to the functional Dlink, but I wanted like a pro to leave the switch all the buns and dignity of the router. but as in the router mode it is impossible to keep the original subnet of the source (WAN) it is logical that I replaced it and tried to force one of the devices on the port to operate in the external subnet Dlink, being connected to the ASUS. That is confused himself, not wanting to simplify the functionality to a simple bridge. - matilda.Schowalter commented on June 7th 19 at 15:43
I understand that links from the Internet comes just one, so to route two devices, as if there is no need. - matilda.Schowalter commented on June 7th 19 at 15:46
, route no. but drink this and not really know how a LAN network only 1 he (firmware Rostelecom rest under the console leaves and they do not work for local network). therefore Glinka useless router. but ASUS replaced it I can't because it's under the optics (Dlink) and ASUS is the most common. so you have to sculpt it (ASUS) to a bundle as a standard bridge and cut it. - Jaime_Brakus22 commented on June 7th 19 at 15:49
and I was referring to ASUS ;). It and newer and more powerful... - matilda.Schowalter commented on June 7th 19 at 15:52

Elementary. Set the router mode to "access point" and he immediately will become transparent and all hanging on this PC will go to lengths and gets a dhcp address.

I did - matilda.Schowalter commented on June 7th 19 at 15:45
