Routers / Switches :: Create 2 Networks On Same Cable Modem With A Firewall?
Sep 14, 2012
how do i create 2 networks using 1 cable modem and 1 router and i would like to add a firewall thinking of using xywall usg20 for the firewall..... the issue is i have a small business with 1 point of sale and1 back office computer.(network1) and i would also like to use an air port wifi to offer wifi to my cleints on a seperate network(network2) not allowing access to network1 and i want a firewall on network 1 to protect the back office and pos system
Trouble connecting to the internet wireless with Motorola SB6120 and Linksys WRT120N. The modem works directly with LAN but as soon as I try to use the router, I can connect to the network but no internet is available.
One of our office´s PC is connected to the network and shows 2 networks, but we have only one modem and one router....and no internet access only in that computer. I had restarted, disconnected, shut down and nothing.....what can I do? I also connected it to another cable form other computer working correctly and didn´t work.
I am trying to connect a Netgear wirless router to my cable modem. I have followed the instructions on the set up wizard but it fails to get a connection with the IP and DNS info I provide.I got the IP address info by connecting intially direct from the modem to the PC and then went to Run CMD and type ipconfig /all. I then started the set up wizard and followed the instructions, turning things on in specific order etc. After input the IP and DNS info it reports an error and tells me to check the address information is correct.My internet is a static IP connection (so it tells me and the IP information doesn't change).
My computer is not wireless so I have needed a wireless router from Time Warner. Directions tell me to connect to my computer. Will that solve the fact that my computer is not built in wireless?
We are a small office currently running a regular network (9 wired, 2 wireless) and also using the "guest" feature (7 wireless) on a Linksys E2000. We have a switch to connect our wired equipment to the E2000. If "A" is our regular network, and "B" is our guest network, is it possible to have 2 routers on 1 cable modem and still prevent network "A" from seeing Network "B" and vice versa?? We are looking to do this because we will soon be exceeding the maximum guest users (10) allowed by the E2000. We have another Linksys router in storage, I think it is a WRT54G, that we would use if this is possible.
We have kids in the house and I'd like to limit their internet access to certain times of the day but because of the great amount of devices they use (phones, tablets, laptops, etc.) the only way I could think of doing that easily was to set up two wireless networks: one that the adults could use 24/7 and the other that the kids could access during certain set hours.
Here's the equipment I'm working with:
DLink DIR 615 wireless router DLink DIR 515 wireless router Motorola Surfboard cable modem S85101U
I plugged the DLink 615 in, set it up for DHCP client and plugged it into the cable modem. I lef the default 192.168.0.1 IP address for the device. On that router, I also reserved the 192.168.0.199 IP address and assigned it to the DLink 515.I also gave the DLink 515 device the IP 192.168.1.1 so I could administer it.I set the DLink 515 to static IP and made the IP 192.168.0.199 and the default gateway 192.168.0.1.I plugged the DLink 515 into one of the LAN ports in the DLink 615.I set a schedule on the DLink 615 to shut down internet access to the DLink 515 at a certain hour and turn it back on at another time.Everything seems to work ok, but at least once a day we have to unplug and plug the routers to reset them.
I have a 192.168.1.xxx network connected to Verizon FIOS via Actiontec MOCA / router. I also have a 192.168.15.xxx network connected to Comcast via Motorola VT2442 router (used for Vonage) and a Motorola SB6121 cable modem.
Each network has it's own gigabit switch connected to each router. The two networks are physically separated but switches and routers are physically side by side.
What is the best configuration to allow devices on 192.168.1.xxx network to communicate with devices on the 192.168.15.xxx network (share printers, NAS, etc), but still have each network served by it's respective ISP, and each device still get it's dhcp, dns, gateway, etc from each respective router?
I have a need to have 2 seperate networks from my comcast cable modem.I was hoping to plug a 5 port hub into the cable modem and then plug both the wrt610n and the wrt54g into the hub. Seem that only one of the routers will get an ip assigned from Comcast.Is there a way to have one ISP cable modem and create two different home networks with the two linksys routers, thus two separate independent networks?
-Network 1: public household use and family (Jane's wireless laptop, household PC's etc).
-Network 2: private household/company use and separate from the public family network (company wireless laptop/company PC, un-secure media server).
how to create a password to access one pc to another pc .like i have 3 pc it is connecting throw switch .ip addresss is 192.168.1.1,192.168.1.2, 192.168.1.3 i want access from 192.168.1.1 to \192.168.1.2 like this here i want to create login password and how to remove password
My Motorola SBG901 Modem/Router combo has stopped connecting to the internet. I have done all the troubleshooting with Comcast and with Motorola and it is out of warranty, so I will have to purchase a new one.In the mean time, I wanted to use it only as a wireless router connected to my Scientific Atlanta DPC2100R2 modem. Is there anyway to do this? Is there a way to disable the modem in the SBG901? Simply connecting with the ethernet cords has not worked. I connected the DPC2100 to the SBG901 via ethernet cord. My computer was able to pick up a wireless connection but there is no cable connection.
When it comes to fiber optics my knowledge is very limited. All I know is that they can carry data at high bandwidth for a long range at blazing speeds etc.My boss has asked me to link several buildings to the network and I am led to believe that joining them through fiber optics to be best since we are expecting a lot of data traffic between.I have done the normal RJ-45 networking with Gigabit networking in my organisation but need your assistance on how to join each of the buildings through fibre optics.So far this is my plan.Draw up the fiber optic lines from the main building to each building.All the buildings have Gigabit Cat6e cabling and network in each.I am planning on using a single mode media converter to convert the end of the fibre optic to the normal RJ45 connector and plug it to each switch at each of the ends of the fiber optic cable .Am I going in the correct direction?I don't even know the gadgematics required except for the cables them selves, crimping tools, the media converter. There is about 300-400 metres in between of each building from the main building.Also, I believe that we need to create cross over cables as in the normal way we do in connecting 2 switches. Your input is very valuable to me.
Using a Linksys E2000 and Linksys WRT54GL (both flashed to most recent firmware), I am trying to set up Network "A" and Network "B" on one modem. I do not want either A or B to be able to see each other for security purposes. Both are secured networks for the wireless connections and have different SSIDs.
After online research, and the inability to find my exact question answered, this is what I did and I'd like to know if I'm missing anything to keep A and B completely separate. Or, if I've done anything that will cause any problems on my network. [code]
I disabled the ability to change settings using wireless connection on both routers.
My workplace currently has one AD Forest. Slowly we have drifted in to two slightly separate businesses and my boss wants us to create a new AD Forest and segregate the users doing each business. Although we will all be in the same office, each side will authenticate to a different DC. The problem is, that we have some resources that still need to be shared and I would like to share them as eloquently as possible without converging the networks too much. The two networks will be in the same server rack but they will logically appear as this:Forest1.local (original)
-Cable Internet -- Router A (192.168.1.x) -- 48-port switch A -- PC/Phones/Domain Controller AForest2.local (new)
-Cable Internet -- Router B (10.1.1.x) -- 48-port switch B -- PC/Phones/Domain Controller B.
The problem I have is that the users in the "new" network need access to a shared folder, shared customer DB, and shared printers on the original Domain Controller, named "DC A" above. I have complete control over both networks but cant figure it out the best way.My main concern is physical access between the networks. How will a pc on the 10.1.1.x network know where printer 192.168.1.2 is? I thought about creating a forest trust in order to assign proper permission but how will they resolve the names on a different subnets? The two "routers" are just simple SOHO type routers so I cant do much there. I thought about connecting the two switches together but don't know if that would work. Wouldn't the data just get passed to the default gateway (router) anyway. The router would then just drop it. I also though about using the 2nd NIC in each DC and connecting them in each other's subnet. But again Im not sure if it matters if the DC's can reach each other or if the PC's would have to be able to reach the other subnet etc. I also thought about just creating some kind of VPN (hamagachi) or whatever to go out into the internet then back into the other router to the network.The problem is wouldnt every computer wanting to access the shared folder have to have this setup. I would like to limit setting things up on workstations and just limit config to the DC's if possible.I basically just want users in subnet two to be able to map a drive and access printers on DC in subnet one.
Two networks. NetA: IP subnetID 10.101.x.x subnet 255.255.0.0. Devices have static-assigned IP's. Only DHCP runs on wireless AP for wireless client connection. IP addressing scheme set by hardware vendor, so not under my control. NetB: IP subnet 10.x.x.x subnet 255.0.0.0. Campus LAN and also not under my control. DHCP supplied addressing. how to get NetA devices to route to NetB?I would like to be able to provide Internet access (via NetB)to NetA devices.
I live in a school residence with a roomate and we both have an internet connection in our rooms but it's two separate networks since we can't see eachothers pc on the network. Both our pcs are connected to a switch and those switches are connected to the two internet connections. I would like to know how to bridge those two networks using a router in the living room. I would also connect a printer and an xbox to the router so we can both access the printer, the xbox can access both pcs and we can access eachother's pc.
Lastnight I power cycled my cable modem, and router in an attempt to get a Slingbox to work. What ended up happening is that after the modem and router came back online all the computers on my wired home network changed their default gateway to the IP of the modem and not the router. Two of the computers are fixed now, but one of the laptops is still not able to get to the internet using DHCP. I can use a static IP with the correct default gateway for the router, and succesfully get to the internet, but then I can't see my server on my netowrk. And the same is true in reverse, in order to see my server I have to go back to DHCP, but I can't get on the internet
I'm going to move offices into a shared situation with 3 companies. Each company will want its own private network so there's no snooping between companies. I am planning on using VOIP for the phone system (Nextiva cloud based). Is it possible to set up the system so that each company has access to the VOIP system but yet remains sequestered in the their own network for everything else. I was hoping to do this with one data port at each workstation using Cisco SPA-303 phones. The way I understand this, is that the phone plugs in to the data port and you daisy chain the workstation off from each phone. Is this possible to do this while having the system I described? Another wrinkle is that I'd also like all the networks to be access shared printers.
I have Multiwan router with 1 port WAN and 4 DHCP Cable modem connected to SF 300-8. I want to connect 4 modem via VLAN through switch. I define Vlan2,3,4,5 on router also in Switch. port 1 on the router as trunk and the other port 2,3,4,5 as Vlan2,3,4,5 with VLAN mode Access. I tag port 1 on every VLAN also Untagged for each port. I having problem when I check the status from multiwan router. all IP address is the same (duplicate). what I want is each VLAN has own DHCP Address. Is that any miss configuration ?
Currently, my Cisco DPC3010 cable modem is connected directly to one of the Ethernet ports on my Linux router. All works quite well that way. However, I'm curious to know if there's some what to separate the router and cable modem over 2 switches?
The coax enters the house in my living room and connects to the CM there. The router is also sitting in the living room, and it's connected to a Cisco SG200-18 switch. I have Ethernet running from my living room to my basement, where a Cisco SG500-24 switch sits. The two switches are connected via a 2xGigE port channel.
I want to move the router into the basement. Ideally, I'd like to move the CM down there with it, but I don't have the necessary coax run. So for now, that's out. But... can I go from something like this:
I tried it, complete with a separate VLAN specifically for the CM traffic. And the VLAN was properly trunked between the two switches. But for some reason, the router was unable to communicate via IP to the upstream. I'm not sure if there are config bits I need to set on the SG200 that the CM is connected to? I thought I'd read somewhere that CMs don't like broadcast technology such as LLDP and/or CDP, so I disabled both of those on its port. Did I miss something else perhaps? Or am I trying to do the impossible?
For what it's worth: the IP connectivity is static. There's no DHCP running between my router and the upstream cable provider. The cable modem is literally acting as a L2 coax-->Ethernet convertor, more or less.
everything was all good, my brother went crazy and unplugged everything.it effects our house phone too, that could be the problem.i just dont know what wires went where. all the wires are the same color.but i know which is which. just again, dont know where.i would like to get it done before he gets home later on.
i have a cable modem and i want to connect 2 diferent wireless router .when i connected i dont have internet trought LAN ports just wireless and i need have internet in those LAN ports.
My network currently consists of one cable modem, and one linksys router.i was given a Belkin N router as a gift, and instead of returning it for a different brand ive decided to keep it. i would like to essentially use a splitter or switch in between my current router and modem.This is the plan. Keep modem and linksys router in the den, use a splitter or switch to split the signal from the modem to each router. Use a 50+ foot ethernet cord running from the splitter or switch through the attic and into another room.
In my office we have concrete walls and very limited wiring. The way it is set up is we have a Verizon DSL Modem that comes in then I have a router with it that splits the signal to 4 other routers that each split the signal 2 to 3 more times. I have to use routers so that it assigns IP addresses.I bought a new D-Line N300 Wireless router with USB imput. I want to attach my Home Media Network Hard Drive Cloud edition to the 1st router (attached to the modem) and then share the data off that hard drive with everyone connected to the sub routers.
I have a SRP547W that I have configured the following way:
LAN 192.168.15.1/24 VLAN1 LAN 10.10.10.1/24 VLAN10 LAN 10.10.2.1/24 VLAN100 PPPOE ADSL Software DMZ going to 10.10.10.x and another to 10.10.2.x - this is working OK
I now want to use the Advanced Firewall features to block all ports except those that I need as the software DMZ forwards everything. When I try to create the rules I get "the values are invalid" message no matter what I try.
I want to create explicit allow rules, followed by a deny all rule for each of the IP addresses used for the software DMZ
Have I got the Subnet Mask Correct for the Destination IP? Or should it be 255.255.255.0? It doesnt make a difference either way

Having some issues getting a site to site VPN connected between two RV042. Any experience getting this to work behind a Motorola SBG9000.Will I be able to get this working? Or will I have to organise a cable modem through my ISP instead
I have linksys router connected to my cable modem. I want to change it Belkin AC900. How can I keep the linksys connected until I have tested set up for Belkin AC900 router.
My Comcast cable modem does not have a 2nd port needed to connect my Belkin AC1200 wireless router. Is there another way to configure this or are my options to either buy a new cable modem or try to upgrade it through Comcast?
