Help a network noob

[Nazarah24]

Hi folks i'd like to setup my Nvidia Shield tablet to stream but i'm having trouble getting it set up. My trouble is from my network setup i have a TP-LINK TD-8817 ADSL2+ modem behind my Asus N900 dual band router the from their Ethernet to a Linksys 8-Port Gigabit Ethernet Switch SE2800 then Ethernet to my streaming PC. I can't get it to play nice and work and i'm not sure how to properly forward ports on the router and the modem and how to get traffic to go through both the router and modem. I'd appreciate any help and advice you can give me i only know basic networking and would like to understand it better so i can solve these thing by myself thanks.

Well first of all, I would say that you'd want to see if you can bridge your DSL modem. This would pass your public IP address through to your Asus router (I assume your current configuration is Phone Line -> DSL Modem -> Switch port on modem -> WAN port on Asus router. We want to have your public IP address that is given to you by your ISP to be on your ASUS router's WAN port. This will prevent you from having to port forward through both devices. You'll be able to just do a single port forward in the asus router. 

 

I think the attached user guide might be for your modem and it gets into bridging a little bit on page 20. Once that's done I can guide you further.

Why not just do port forwarding on the TPLink modem?

Page 29 details how to do that exactly. Then you can just plug the wireless router into the modem via a LAN port and have the TP-Link do all the DHCP/NAT and disable that on the N900

This is currently how my modem is setup.

That'd work too, but the modem isn't as powerful or as nice as the Asus N900 which is why I figured we'd leave as few tasks to the modem as possible. Either way though.

 

Can you post a screen shot of the configuration in your N900 as well so we can see how you have it configured?

Those are just the internet settings for your DSL line.. they really dont tell much..

 

Do you have somewhere in the router where you can do DMZ or something like that?

I think the key is the encapsulation says that it's bridged. So I think the modem should be acting mostly as a media converter and should allow the router to share the public ip address which would make it to where the only place the port forwards would need to be configured would be on the N900. I'm not super familiar with this model so if that isn't the case I agree that a DMZ would also get us to the point where only one set of port forwards would have to be done.
