Im behind 2 routers, I can only access the router's configuration from the router that I am directly connected to right now by going to 192.168.2.1

Is there a way to connect to the other router too instead of putting a cable directly from that router in my or another computer?
It's for port forwarding.

Im seriously confused. Maybe diagram what you mean?

Like this is what a see from your description

Computer 1,2,3 etc ----> First Router -----> Second Router (for port forwarding) ----> Modem

And you can only access First Router by 192.168.2.1.

Why do you want to go through 2 by the way?...

Also is my diagram correct?

Yes

My pc ----> 1st router which I can access -----> Second router -----> Modem

To succesfully open a port, I have to open the port on both routers right?

yes... but i still would like to know why you want to open both?

I have an idea, id like to know why you want 2 routers first.

Well, if you think about it. He may be in a college and he has a router in his dorm. And the college has a router behind the network hub.
Or same thing for work maybe?

You will have to port forward on both routers.

Yes I figured that but I need to know if it's possible to access the second router from my computer.

I'll repeat my question

My PC -----> router ------> router ------> ADSL modem

From my PC I can access the router directly connected to me by going to 192.168.2.1 in my browser, but is it possible to access the second router from my computer too? I know I can directly connect the second router to a computer and then access it by going to the router's default IP but I can't swap the wires because they're in the ceiling :/

I have the same problem, I'm using two routers.

Computer 1,2(both of them are mine, in my room). -> Router 2 -> Cable to Router 1 -> Modem.
I can only access Router 1. Not Router 2.
Any ideas?

Okay well i just want to say that it is pretty stupid to purposely have to routers... from what i read at least...

I think this is what your going to have to do...

1st) Port Forward the first router normally.

2nd) Unplug the first router and switch it with the second

3rd) Portforward the second router but instead of puting 192.168.x.x put your first routers IP address

I think that may work..

I tried to use 2 routers before, it went.

computer -> wireless router -> router -> modem.

Don't use the WAN port on the second router, just use the LAN port on it to connect to the main router, and everything will work fine, as though it were just a switch. If you're trying to segregate computers on your network, you'll have to put them on a different subnet, and set up port forwarding, to forward the port the admin utility the primary router uses, to the IP of the PC you want to access it from router. A lot of routers use port 80, and if you forward all communications from port 80 to your secondary router, you'll be in for a fun surprise when you try to use the internets. Disable the DHCP function on the secondary router to prevent IP conflicts. Because of the way residential routers function, it may not even be possible to access the admin panel of the primary routerbecause of the way the NAT handles traffic, I can't say that I've ever tried it. You shouldn't have any problems at least networking them though if you remember to disable the DHCP on the secondary router, and set different IP's on the routers.

I need to access the second router from my computer, I CANNOT PUT THE CABLE DIRECTLY IN THE SECOND ROUTER because all the cables are in the ceiling/floor (depends from what store you look at it) and I can't move them.

Oh well, then you cant...

Also... Now is the time to tell us why you want to do this...? Seeing as port forwarding is equal in security (IMO... but maybe not?) and possibly better (less to travel through).
