    I can trying to config two routers with RouterB in it's own network.

    RouterA=router for house
    RouterB=router for my room

    Both for LAN and Wireless

    Connection between the two are from switch of RouterA to uplink of RouterB

    RouterA:
    Set to have DHCP
    192.168.A.1
    255.255.255.0
    192.168.A.1

    In advanced routing, it is set as gateway:
    192.168.B.0
    255.255.255.0
    192.168.A.105

    RouterB:
    DHCP disabled
    Static @ 192.168.A.105

    192.168.B.1
    255.255.255.0
    192.168.A.1

    Nothing in advanced routing. Do I need to set this part up? I've tried selecting both gateway and router (not filling out the table) but seems the same.

    My computers are set for static ip using RouterB info and I have a chunk of ports fowarded from RouterA to RouterB. I also have these same ports forwarded on RouterB to my specific computers.

    I have no problems with connections inside my network accessing the internet and gaming but when I am accessing my computers from outside, remoting in, ftp, etc, I cannot seem to get a connection; it seems to be dropping packets.

    What am i doing wrong?

    Thanks

    Why do you need a router for your room only? Having 2 routers in your house is going to have conflicts with the signal

    If you send it up properly, there would be no problems :).

    RouterB is mine which I've had for quite a while and has served me well. I see no reason to buy more junk if I dont need it. I have multiple PCs on both wireless and wired. I also want to secure them. Without RouterB I would have no wireless and only one wired. My setup solves all this.

    Nice link for a one network setup... but RouterB is on it's own subnetwork...

    The easiest way to do it is to have a Router and then a hub. No setup, no conflicts. Yay hubs.

    i would suggest a switch over a hub. a hub shares its bandwidth, while a switch gives each computer full bandwidth to it.

    pb,out.

    2 Routers basically are used to secure 1 network to another network and enabling specific boardcast and also used by companies. By the way, it may persists some latency on your network. :)

    Correct me if I'm wrong for below configuration.
    I hope this might help you.

    Thanks! Finally a real response.

    A few questions...
    The route command at the end of your post, is that for ALL computers regardless of which router it is connected to?

    Also for the routes, are they both in gateway? Gateway + router?

    You said "Optional, enable Wireless either Router A or Router B." Does this mean you cant on both (I need it on both since the wifi signal apparently doesnt travel between floors)?

    I fail to see how your configuration is different from mine though... Only difference is with w.x.y.z, I am changing y.

    The route command which I used before is to share access among your PC in DMZ. Which route? Router or PC?

    I believe you can enable Wireless for both Routers because, in my experiences, it seems both routers have its own subnet and different signal. Therefore, it shouldnt be a problem to enable both Wireless.

    IP ADDRESSSSSSING. This may require some study on IP addressing on how to use subnet. If you familiar with subnet then you are free to assign any IP you wish.

    Do you able to provide me, all your setting? I also wanna learn more about networking.

    I'm very appreciate if you would correct me.... ;)

    Router vs gateway selection. Linksys app lets you select this option in the advanced settings. I selected gateway and where I put the routes. This part in your msg would go on the page I'm talking about
    Static Route:-
    Destination: 192.168.100.128
    Mask: 255.255.255.128
    Gateway: 192.168.100.2

    But there is also a Router which you can select. If you select this, below there is RIP and below that you can add the routes.



    My current setting are still the same as my original post where A = 1 and B = 5. Since I can actually access the internet without problems I have not tried to change anything yet. The problem is accessing my computer from the outside, ftp, web server, etc. For this, it takes more time since I need others' help or coming here to work to test it :). Will report back when I get some results.

    I had miscommunication with you.. And now I got it. My apology! ;)

    You means you're not able to access FTP, SMTP, POP and bla bla from outside right? If i'm not mistaken.
    Is there any port forwarding selection in your router? Or you have done that?

    ok in a situation like yours I let router A do all the work and configure router B to simply be a switch. ok this is my post I copied from another post of mine because I'm lazy right now. assuming your personal box is a linksys:

    step 1: log into linksys box and give it a new IP, I usually use one after the other router so if the router defaults to 192.168.1.1, then give the linksys 192.168.1.2 so you know how to get back to it. After you do that you'll have to log back into it on its new IP.

    step 2: disable the DHCP

    step 3: change the mode from "gateway" to "router" (very poorly worded by linksys IMHO but its what you need to do, should be labeled router/switch or something of that effect).

    step 4: plug the cable from a LAN port on router A to a LAN port on the linksys(router B), NOT the WAN.

    step 5: you can disable the firewall and such on router B as well if you want since all traffic is going through router A.

    That turns the linskys into an access point essentially leaving the first router to handle all the routing and IPs, done it countless times in many installs.

    No need to mess with different net masks and **** unless you are trying to keep the networks seperate from each other.
