Using a hub with a NAT dsl router

Hi,

I'm looking to share a broadband connection with my 4 housemates. I don't want my machine to act as a gateway.

I want to use a dsl router so any client can connect any time of the day with out the need for someone else to have their machine on.

I will use a dsl connection with 1 dynamic IP address that is assigned at dialup.

I have seen a 4 port dsl router that uses NAT. My question is, can I plug a hub into the 4 port dsl router to allow more than 4 simultaneous connections to the web?

Thanks

lrmoore is the resident genius here (not to mention damn quick to scoop the reply :) and I would 98% agree, but I would like to add that it can depend on the device.  Some will limit the number of users allowed at any one time (like sonicwall for instance).

Agree.  Be aware, you will either need to use a port which can do auto MDI-X or which has a little button which will turn it on or off.  This will cross the wires and allow the sends and receives to be on the right pins.  Otherwise, you will need to obtain a "cross-over" cable which will do the same thing as the MDI-X button - cross the sends and receives.

>>whats auto  MDI-X?

When a port will sense the type of connection (straight through or cross-over) and automatically reconfigure itself to match the type of connection.  Usually only available on newer equipment - usually costs a bit more.

Auto MDI-X automatically detects the port and or the type of cable used, in other words, you can connect any device with either sort of cable and it will automatically decide how to use it.

If you have another device, eg. a hub, with an uplink port, use this to connect it to a standard port on your original device (providing it allows the connection), this serves the same purpose as a crossover cable.

Any recommendations on what brand is best value for money when is comes to DSL routers?

I have a budget of around 50 pounds.

Any brands you recommend avoiding?

Linksys all the way..
Stay clear of NetGear
Stay clear of D-link

Highfive + Dolby Voice = No More Audio Complaints!

Poor audio quality is one of the top reasons people don’t use video conferencing. Get the crispest, clearest audio powered by Dolby Voice in every meeting. Highfive and Dolby Voice deliver the best video conferencing and audio experience for every meeting and every room.

I don't know what brands are common where pounds are in use.  I've had good results with Linksys and it's what our company has standardized on supporting for users.  

Personally, I don't think Microsoft, being a software company, does networking very well, so I would avoid Microsoft routers.  

D-Link, Netgear, SMC are all about the same - fine.

Found a good linksys wired dsl/router. It does however still require an external dsl modem.

Would that just be a standard USB modem or does it need to be something special?

Any modem that provides the same interface as your 'WAN' interface would be fine. Usually this means your DSL Modem will need a CAT5 or ethernet interface for the 'LAN'. If your DSL modem only has USB then it probably won't suit.

Word to the wise - avoid USB when talking networking.  Just get a regular Cat5 or 6 cable with RJ-45 connections and connect your DSL modem to the router.  Works like a charm.

...And FWIW, IMO at the bottom end of the market here, Netgear are USUALLY better (more reliable, faster, better interfaces and support) then Dlink, SMC and Surecom etc.

I can't believe it, I login to answer the question and there are already two answers!

If you only have a USB modem provided by your ISP (most have USB and CAT5 connection), try getting one from them with an ethernet connection, but don't mention your setup in a hurry, some ISPs don't like people sharing the connection, even though it happens all the time.  Most of the tech departments will be happy to work with you, although they're 'not supposed to'.

Yes, it'll work fine.  I have a 24 port switch sitting behind my cable modem.  For small installations I use Linksys and you can get it with a 8 port switch integrated.  I would avoid the hub as they are so yesterday.  A simple little switch works great and is really cheap.  I've had breat luck with the little netgears.
