Two seperate networks sharing one internet connection, How?

Hi all,

A friend of mine runs a home business employing part time staff. He's got 8 computers dedicated to the business, running W98, W2K, WinXP on a peer to peer network. Everything on the network runs fine.

Currently only 1 machines is connected to the internet via a dial up connection, it's not shared at all, anyone wanted to surf the web must be at this workstation. He's planning to get ADSL very soon.

Ultimately he wants to share this ADSL line with all the 8 networked machines.

He also have 3 kid's computer that he'd like to be able to surf the web via this ADSL connection. However, he doesn't want the kid's network to be able to access / interfear with the business network.

How would I be able to achieve this? Putting the kid's network in a different subnet? That means I would need to have 2 routers in the network? If that's the way how should the routers be configured? I think I have a general idea but just wanted some confirmation.


Thanks
 
two routers will work, as long as the second router can work with a private IP as its WAN address.
A router two inside interfaces will also do it, allowing two distinct LAN segments.
 
skyking: So you're saying that not all routers can support a private IP on its WAN port? A router with 2 inside interface??? Meaning routers that can support 2+ different subnet / class of address for its internal LAN ports? Ok so I should point the second 'internal' router to the first 'external' router as a gateway? I should connect the WAN port of the 'internal' router to one of the LAN port on the 'external' router?

Macro2: By ACLs+switch you are referring to NTFS's ACLs? Well I've thought of that one too but it's a bit hard when there are W98 machines involved. Or are you referring to something that I don't know?! 😱

Thanks for the input. Will start to look up some routers now. Since his ADSL connection includes a modem + router device I will just need to get him a second router.

Yes, some routers do not accept a 192. or a 10. for a wan addy.
Yes, hook the wan port of the second router up as a client to the first. make sure they are set to different gateway settings.
I have done this with the microsoft wireless router successfully.
 
Hi

skyking: Thanks for the info. Now I'll go answer my friend with confidence 😀

Macro2: Unfortunately I don't have much if any knowledge in configuring a Cisco router. I'll take a look at them anyway for self education :light:. Still thanks for teaching me something new.
