How could I connect to my gateway behind my router?

So I have my main desktop, secondary desktop, a router (Netgear Wireless-N 150 Router WNR1000), and a Xfinity SMC Gateway (SMCD3GNV). My internet connection comes from the wall too my Gateway, which has 4 Ethernet Ports and wireless capabilities. Then port-1 is connected to my Netgear router, and port-2 is connected to my secondary desktop. Then on the router port-1 is connected to my main desktop.
Is there any way to access the device webpage for my gateway on my main desktop? My Windows network map stops at my Netgear router.
Specific Information:
~Main Desktop
-Windows 7 64-Bit
~Netgear Router

~SMC Xfinity Gateway

Am I missing any necessary information?
Answer #1
As far as I know, only way to do it would be to connect the pc directly to the Gateway if you have it in bridged mode.
Answer #2
Your setup doesn’t make any sense,You don’t need the extra router (Netgear),The SMC alone would do (It is a VOIP wireless N router
with an integrated cable modem after all)
Answer #3
I have my second router because I want to disable the wireless on the SMC and open all ports, I plan on allowing incoming connections to my secondary desktop. But I definitely don’t want my main desktop wide open. If you have a better suggestion I’m open to anything.
If I can’t move up the line, can I move down? Is my secondary desktop able to view my Netgear?
Answer #4
Not following,What exactly are you trying to achieve? Do you even know how routers work? You got no practical
reason to use the Netgear in addition.
Answer #5
Not following,What exactly are you trying to achieve? Do you even know how routers work? You got no practical
reason to use the Netgear in addition.It’s in essence a DMZ for the secondary desktop. Though we need more information to help. Do you plan on running a server or something on the secondary desktop? DMZs are not necessary if you forward the ports unless you absolutely require the computer to be 100% open.
Answer #6
Change the ip adds of each box to what you want, then log into them
Answer #7
Thanks andy1033! They both were on 10.0.0.1. I changed that and was able to connect to the SMC webpage.
Now, I have to figure out the password.
What are the reasons for the SMC to have a battery slot on the bottom?
And -paroxysM^ I plan on hosting quite a few things, I enjoy trying new things out so I will be installing and uninstalling a bunch. I want to learn how to build a webserver from the ground up, and I’ve got a few other ideas as well. FTP, Music Streaming, VMWare with remote connection, and anything else I come across that I find interesting. So for me, it is easier to just throw everything wide open. Plus, It is just for myself and 2 friends so I’m not too worried about incoming connections. Plus my router, firewall, should help with that. Someone also recommended Snort, so I am going to look into that.
