Network question

okey, so here is the question. I have an exsiting network at a friends company. This company however is owned by 2 different people and there about to have a fall apart. So now the two people are mad at each other and wants to be on a different network. This is where i would need the help.

1. They have broadband internet from a cable modem and a router, then connected to a 10 port switch.

Since boss A doesnt want to share anything with boss B, but yet they want to share the internet connection, can i just install a second network card on all of Boss B's computers and set up a file server on there side, while holding onto the shared internet connection of A?

Or better yet, can i just drop another switch to the router, and then pull out all of BossB cords on the original 10 port switch and just move them over to another 10 port switch?

I was thinking of just setting up different domains entirely, but it seems like Boss B wants her own file server that Boss A cant access, and they want DHCP on the network so they can just add more computers and take them off at any given time.

Boss A had the ip of each computer configured and having to call Boss A's tech to come out everytime they got a new station is the problem. Not to mention that Boss A's server tends to fail every now and then, and Boss A is being cheap to replace the server with a new one.

Any suggestions or comments is greatly apreciated!
 
You could possibly (it depends on the ISP, it worked with verizon DSL at my parents' house) put a switch behind the cable modem and hand two routers off of that. One router for each boss. The networks would be separated, but utilize the same internet connection.
 
so i could do this then your stating?

Cable Modem -> Switch first -> Router A / Router B -> switch 1 to router A and switch 2 to router B?

Pretty much. 🙂
 
LOL.

I wonder what more serious problem is?

The fight over the company, or being so cheap that they can not add another Connection.

In any case, you can buy two inexpensive Routers ($20 a piece) and connect them to the main Router.

Example: Main Router 192.168.0.1

Regular Port 1 on Main Router to one new Router?s WAN Port and configure the Router's LAN side to 192.168.10.1

Regular Port 2 on Main Router to second new Router WAN Port and configure the Router's LAN side to 192.168.20.1

Any thing on the Main Router can be shared by both Networks.

Any thing a secondary Router would stay segregated.

Wouldnt i have to disable DHCP on the secondary routers tho? I thought overlapping two routers with DHCP would cause conflict. :\

YES i know i wish the two people would just grow up and just replace the file server instead of BOSS B being hella angry and Boss A and buying a privite file server for herself.

*sigh* sometimes people should remember there still not inside the stupid sandbox fighting over the shovel. :\
 
nope, Jacks config would work great with the 3 routers. DHCP is only served on the LAN side, and you are connecting WAN of routers 2 and 3 to LAN of router1
 
sorry for being so noobish in networking. This is one area i am not totally informed in.

So according to jack i just need to disable the DHCP on the primary router? and enable them on the secondary router? and i can have two independant networks sharing 1 internet?
 
you could leave it on everything, as your WAN ports for you secondary routers probably default to DHCP. THe big thing is tho change the LAN addresses/DHCP scopes for all 3 to something in different subnets.

192.168.0.0 255.255.255.0 for router 1's subnet
192.168.1.0 255.255.255.0 for router 2's subnet
192.168.2.0 255.255.255.0 for router 3's subnet

Take a look at this page, it is written for another purpose and has only one secondary Router, but the principle is the same as what you need to do.

Or, you get get a cisco switch (29xx series) and set up Vlans. With that you definitely don't have to worry about them accessing each other's stuff.
