Trouble with switch

AndyRN · October 3, 2015

I'm not sure where my problem is. I have included a drawing of my home network. The issue is, almost nothing works when connected to my switch. The only thing I have successfully working off my switch is my Chamberlain garage door gateway. I have to connect everything to the router if I want internet access or if I want to be able to see it on the network. Today I tried to connect my Magicjack to the switch and it wouldn't work. Hooked the NAS to the switch and I can't see it. (The NAS spits out that my I.P. for the NAS is 0.0.0.0)

I appreciate any help. When it comes to networking I am helpless.

1. put the switch behind your router.

2. ?

3. profit.

you should NEVER hook up a device straight up to your modem without a router in between.

even if only to save up on public IPv4 address space.

I really dont see any problems hooking anything directly to a modem - its pretty common practice in SMBs (not with unmanaged switches tho)

But yeah, change the router and the switch' position and maybe install an access point for wireless where your router is now..

well... a lot of ISPs have a very limited amount of public IPv4 adresses to give out, so they limit the amount each user can claim.

before my isp switched to modems with built in routers they had pretty much the setup OP described, allowing for up to 4 IPv4 addresses per client.

times have changed tho, and especially with the "we're all out of addresses" issue in NA, ISPs are really screwing down on the usage of public addresses.

When I originally bought this switch and my new ASUS router last year, this is what I did; however, nothing worked. couldn't get on internet, couldn't see plex server, couldn't see NAS. Then I hooked up the way I had shown and it worked except I couldn't use the switch. Then life got in the way and I just let it be. Now I was out of connections on the router and I needed the room. So after I posted this question, I tried to do connect it one more time, the way you suggested, and now it works. Go figure. Thanks.

Because most people only have 1 public IP? Also most devices cannot act as their own gateway. This is the main purpose of the router afterall. Additionally, since only one IP address is available NAT is needed, which is usually performed by the AIO (router).

We can also see here that all the devices are meant to be on one local LAN but with the way this is set up it cannot be achieved.

You guys are sweet I do know these things and a bit more, that is why i said what I did - you are both totally right in your obvious statements

Almost no private customers will get a solution with a Service gateway like a Cisco ISR 880 or 890 series (or some fiberunit like the one LMG has or a sonicwall or a Juniper SRX) or a solution as the above with a modem, a L3 switch and 2 public IPs (one for management and 1 for the customers disposal)
