Solved Home network setup help needed please

Specs: Windows 7, i7-3770 3.4GHz / 8 gigs
Hi all, I am setting up a small network at home and need some help. I have a Bell Connection Hub which is a modem + router device with an ip 192.168.1.1, 255.255.255.252. Since it's feature is no where near my D-Link DIR-825 router, I enabled the DMZ on the Bell Hub and assigned it to the D-link router so the Bell Hub is basically used as a modem only. The ip of the DIR-825 is 192.168.2.2, 255.255.255.224 and it's connected to an Asante GX5-2400W switch. Everything is connected through cat.6 cables except a couple of wireless devices. The switch needs an ip and gateway subnet and that's what confused me most. Since this is the first time I'm setting up a network and I only have little knowledge in networking, could someone please direct me to the correct settings on those three main devices? Also, how should I set the ip range? I would like to add a NAS for file storage and sharing in the near future so please include that in the equation as well (if applicable).

Thanks a million.

✔ Best Answer
You should see if you can configure the bell to bridging not nat. This way the dlink will get the public ip address instead of the bell. No dmz needed.

Since you are using subnet 255.255.255.224 which results in only 30 available ip I would recommend the following

Router 192.168.2.1
Switch 192.168.2.2 [you don't need a gateway or dns entries. This is just for local access/management]
Router dhcp scope 192.168.2.3-30

Thanks a lot wanderer for the fast reply. I will try to bridge the Bell Hub and follow your recommended settings. You mentioned local access/management to the switch, it does have a lot of control of the network options. Will I still be able to simply key in the switch's ip address on any computer in my network and get access to it if I don't provide a subnet? BTW, are the ip and subnet of the Bell Hub ok to keep as is or it doesn't matter?

Thanks

You need to provide the subnet mask. It just doesn't need a gateway or dns entries. Not like you want it on the internet [that would not be good]

If the bell is in bridge mode it won't have a ip address anymore and will act just as modem passing the public ip to the router.

If you can't put in bridge mode the present ip scheme is correct.

Thanks again wanderer but may I ask you what the switch's subnet should be set to?

According to the forum at BELL, the connection hub doesn't have a bridge mode but can be set to a "pass through" mode by hard resetting it to default and let the router handle s the pppoe. I will also try that, hope everything works happily together.

Thank you.

This is the subnet mask you are using
255.255.255.224
You would use it also on the switch.

if your router supports pppoe on the wan interface you can dump the first router all together. It appears your dlink does support pppoe

Hi wanderer,

I have setup my network as you recommended and everything is working fine. Thank a lot for your help! There is one more question I would like to ask. While punching in the numbers into the switch, I kept getting a message saying the subnet must match to the gateway's and it refused to accept my subnet unless I also give it the gateway IP, and without another choice, I satisfied it. Will it actually put me at any kind of risk if the switch is holding the gateway's info? I may a bit of a paranoid but it's always better be safe than sorry.

Thanks.
