Cross-Subnet Samba Connection

[snakeplisken47]

So, I bought an R3 shortly after my last forum post (Thank you, Fraiser and Darkness! It has given me some issues, but nothing so bad that it's made me want to stop using it forever). However, I now have a bit of a complicated issue.

For some context, below I (hopefully) list most of the useful information.

My Setup:

ISP > Asus Router LAN PORT > R3 WAN PORT

I have a Samba share set up on my Asus router.

• Asus Router Model: RT-AX88U
• Asus Router Firmware Version: 2.438
• R3 Gateway: 192.168.77.1
• Asus Gateway: 192.168.50.1
• DumaOS Version: 4.0.540
• App Version: v4.0.192

Hopefully, that covers most of the important details.

The Issue:

I’m currently attempting to access the Samba share on the Asus router from my R3. I've tried the following configuration without success and have also attempted the inverse setup on the Asus router.

The odd part (which is likely due to my own lack of understanding of how this works) is that I can ping 192.168.50.* IPs from the R3.

Route Configuration:

• Route Name: Asus
• Network IP: 192.168.50.0
• Subnet Mask: 255.255.255.0
• Gateway: 192.168.50.2
• Metric: 2

Thanks for your attention! Sorry if I sound stupid—I kinda am.

You don't need a static route, have you tried without this?

Yes, Windows just (Does what i presume is ping it?) try to connect, fail, repeat

Have you got the R3 in the Asus DMZ? You'll need to do that really I think to have it working properly

I Added the R3 to the Asus routers DMZ, and it still appears to be exhibiting the same behavior, im sure the issue is glaring me in the face and im either too in-experienced or to blind to see it

Have you set a static/reserved IP for the media server so it doesn't change? Check if the IP has changed from what you entered on the PC and update it if necessary and set the IP as reserved on the router and that should do it

The Samba share is hosted on the router as far as im aware, its literally just a Seagate drive plugged into the usb 3.0 port on the Asus router

Oh I see, that makes more sense, well you put the share in the DMZ when you needed to put the R3 IP in the DMZ on the Asus, that may be it. Make the change and then see if you can access it when connected to the R3.

The R3 IP IS in the DMZ, As you can see here, wouldnt 192.168.50.1 be the samba share IP, AND the gateway? because the R3 Has 192.168.50.2, and thats whats in the DMZ

[Netduma Fraser]

My mistake, misread. Does it say in any documentation for the samba/share feature that in order to be used devices have to be connected to the router?
