Routers / Switches :: Setup DMZ By Using Home Router To Prevent Attack?
May 5, 2011
Currently in my office have a TPlink wireless router (WR1043N), and Dlink 615 router.Below is my office's network organization.Internet-->TPLinkRouter(192.168.2.0)-->DlinkRouter(192.168.0.0)We want to host a demo website but we are afraid our network being attacked. So we wish to implement a DMZ network to hide our internal network from outside. My question is can i setup a dmz network with the above capabilities by using home routers?

I want to setup an home network with a wireless router and use multiple switches for wired connections through out my home. I currently have an Airport extreme hooked up to a cable modem and a leviton gateway hooked up to the Airport. The 2 computers connected to the Leviton are on a windows 7 homegroup and share fine, but won't share or discover any wireless device connected to Airport. My main goal is to have a wireless/wired network with all computers sharing information with each other. I want 2-3 wired switches/gateways with a min of 2 devices connected to each, connected to my wireless router whiich is connected to cable modem.

Is there anyway to block a DDOS attack? I dont know to much about DDOS attacks and how they work, but i think i understand a little bit of it. Is there no way to configure a firewall to detect rapid, spontaneous,continuous amounts of fragmented, random data coming from an IP address? Wouldn't the data coming in from a DDOS server be somewhat distinct from data that flows normally

I have 2 linksys routers installed on my home network. The primary router is a linksys WRT360n and is stationed inside the main home, while the 2nd is a linksys WRT160N located in my office. I've connected them via the lan to lan configuration and have disabled DHCP server on the 2nd. I can access the 2nd router via my primary PC but am unable to access the internet or see the primary from the PC connected to the 2nd router.

The router was working fine when it was setup but was disconnected for a short while. There is now no recognition of the router and the install cd was misplaced...

I am following instructions I found to set up my wirelss network, but am having trouble configuring my router. I'm specifically at a standstill, because I can't connect to http://192.168.1.1. I pinged the router and got a response and went to run/ip config to confirm I have the right URL for the router, but still not able to get to the URL.

My IPTV connection works fine so far but as soon as I start watching TV I can't use my WiFi connection anymore. My router is an "Alice Modem 1121" (SIEMENS S1621-Z220-A) with 4 LAN ports and a WiFi interface (4th LAN port provides the IPTV). It is directly connected by wire to my PC's ethernet card for the IPTV and the internet is provided via the WiFi. When I activate the LAN connection the WiFi and internet connction stays up and requests can be sent but nothing returns anymore. Another device (iPod) has no problems with accessing the internet while IPTV is in use. I also have a Netgear WNR1000v3 router which I tried to use as AP instead but it's exactly the same problem. Unlucky the Netgear router is not supported to use dd-wrt firmware yet (I've found a step by step guide to prevent multicast floods with dd-wrt/ebtables). But maybe the Alice Modem can handle this problem on its own. I read some stuff about VLANs and splitting them but I have no clue how that would look like.
The "nas_0_1_34" is for the IPTV.

Just bought myself an 825. I've got it set up and working, but how do I prevent wireless users from accessing the setup pages for the router?
I only wish wired access to the setup pages. I'm used to doing this on my old linksys, but can't find the setting on the new router.

I'm trying to set up my home network with two routers. One as the LAN router and the other as the access point. I have a really nice router and an older router, I'll just leave it at that. One router will be connected to the modem, the other in my game room for the wireless access point. I want to use the nicer, newer router as the LAN router or the wireless access point?

I'm wondering if anyone knows to set up the switch so that when I'm connecting via SSH, the switch doesn't prompt for a username if I supply one in the initial connect request? For example, we usually connect by typing something like the following at a command prompt:
ssh johndoe@10.10.10.10
Then the switch would prompt for a password. I've tried this on the Cisco SF302 but it still prompts for a username, and then the password.

Is blocking echo request to prevent ping sweep the same as having a firewall in stealth mode? And how could someone ping sweep from outside if you had a firewall at all?

Until recently when we changed the router at work, I can access work files from my laptop and notebook from home. It seems the problem is probably from my home wireless router supplier by-aol as I can access work from my laptop anywhere else except my home. But then I have been able to do so until the work router was changed so i don't know what could be wrong?

At my company, we lease 3 static public IP addresses from 1 ISP. We want to have 3 separate networks that each use one of the IP addresses. Network 1 is the computer network, network 2 is the VOIP network, and network 3 is the security camera network. I am trying to determine the best way to do this. I have come up with 2 solutions in my head, but I'm not sure if they will work or not. I would like to get some input. Solution 1:Solution 1 looks something like this. Fiber box -> Router-> 3 switches. There would be one WAN input on the router, that would have a static route to 3 different LAN ports. For example, address 24.244.208.101 would be assigned to LAN port 1, 24.244.208.102 would be assigned to LAN port 2, and 24.244.208.103 would be assigned to LAN port 3 (by assigned, I mean have a static route to it). Is there some type of router that is capable of doing this? Solution 2:Solution 2 looks something like this. Fiber box -> Switch -> 3 Routers. The ethernet cable would run from the Fiber Box to a switch, and then 3 routers would be plugged into the switch. Each router would have the Static information configured in them. Would both of these methods work? If so, which would be the best way to go?

We are in the process of switching to a new internet provider in our office and have run into some problems. Our old setup was with AT&T, where they provided a managed router which linked to our internal switch and also provided NAT to the internal IP of our email server.Our new setup right now is just the internet coming in through a cable connected to a switch, we were told we needed to provide our own router. Someone donated a Cisco 2900.What should our proper set-up be? Should the internet come in directly to the router and then to our switch, or should it go to the switch they provided, then the router, and then our switch?Also, there seems to be some confusion about whether or not we need anything else to get the internet to work. There are slots for network cards in the router. Does it come with at least one built in we can use, or do we need to provide one?

I had this small internet cafe with 15 units pc. and browsing the web is not that stable. i have to unplug the internet modem everytime i can't connect to the internet.I think it has something to do with the settings that was in the router since it was just configured by a tech guy which i think not 100% sure of what he did, though it can connect to net for sometime but most of the time it is down.

Although we have a moderately wired house with cat6 cables runs in many of the rooms that all end in the basement, I am currently having trouble since I cat stream audio and video files from my desktop in the den to the netbook and receiver in the family room. All computers are hooked up by cable.I have tried a friends advice to plug in the exact IP address of the desktop (and vice versa on the netbook) but still the netbook cat find the desktop nor can the desktop find the netbook. I have tried home sharing in Windows 7 to no avail as I have been prompted to initiate a home network both on the netbook and the desktop when I think it is suppose to be initiated on one machine and same home network joined by the other.DSL Modem --> Linksys WRTGL router running Tomato --> switch -->various rooms (cont.)Family room (one of the various rooms) has a Buffalo WZR-HP-G300NH AirStation (with one USB port) --> 1) netbook and 2) Denon AVR receiver (with network capabilities)I have a switch in the den and the desktop and laptop computers can read off each other through folder/drive sharing even with Kaspersky Internet Security running in the background so I'm sure it's not Kaspersky meddling with my network sharing. If both are on the wireless network, the netbook can access the desktop and vice versa.Is it possible for the netbook to read off the desktop based on my current set up? I can't bring the desktop down as we use them in the den and will not have room for it in the family room. I am not inclined to purchase a stand-alone HTPC at the moment if there is a network sharing

I have VOIP and was provided a modem, a Tilgen Router (Vood 452_A). I also currently have a Linksys WRT54G router. I also have a home surveillance system with a DVR that can be accessed via the net. I am trying to allow the ports to open so that traffic can navigate down to the DVR.My IPs:My VOIP has provided me with 6 static IP addresses. For sake of this issue they are:
67.xx.xxx.153, through .158My subnetmask is set to:
255.255.255.248My Settings:
The Modem is connected to world. To the modem I have the Tilgen Router connected. The Tilgen is set with an ip of .153 and the subnetmask listed above. DHCP is turned on and has IP range set for .154-.158. It is set in Bridge Mode with NAT and Firewall turned off. To that I have the WRTG54G router connected and assigned the router an Static IP of .154.. The cable is going into the Linksys WAN port.From a computer connected to a LAN port on the WRT54G, I see my public IP as .154, currently my internal IP is 192.168.1.15 so I believe I have to assign one of my Static IPs to this PC, however when I try to connect to the Linksys Router (.154) from the outside web, I am get a time out error. (also from a ping test.) My thoughts are to assign the Linksys to DHCP and use a range of .155-.158 to give each lan item a static IP. My question is will this work? Will each item in the network have its own IP and if I forward the port to the DVR that i needed, ie 80 for web client or 6100 for desktop client, will that forward through?Or do I set it to Router Mode and use the Tilgen to assign the ips.
On the Tilgen I also have an option for a DHCP relay or to turn off DHCP.
For clarification here is the setup chain
Broadband/DSL Line>>Tilgen Modem>>(LANPort1)Tilgen Router(LAN Port2)>>(WAN) Linksys(LANPort1)>>DVR/Computers
Found this walkthrough on setting the WRT54G into a Switch. If I did this, in theory the VOOD would assign those computers/dvr connected downstream via the WRT54G a static ip from my range set on the router. Then in theory I would not need to port forward port 80 since the DVR would be on its own public IP.?

We recently moved 8 pc's from a room where they each had port on the switch to a room where there is only one port for all of them. I setup a DLINK DIR632 Router in there and they connect thru the one port thru the switch to the gateway which gets them out to the internet.The problems is I need to be able to remote desktop into these 8 PC's and I need them to be able to print to the network printer. I am using a Linksys WRT54G Broadband router as the gateway connecting the switch to the internet. The DLINK's dhcp server is on for the 8 PC's. The Linksys' dhcp server shows the DLINK as IP 192.168.1.19 on the network.I know I have to use advanced routing settings but I'm not sure about how what to make the subnet mask and IP's on both routers. I believe I need to turn off the dhcp server on the DLINK and have the Linksys' dhcp server serve all of the PC's but I'm not sure if thats the best way or if its possible.. I don't want to hack out fix only to find it breaks 3 days later.I used to do this stuff all day long in the 90's but its been a while and to me its like calculus.

I have a Dell switch setup with 2 Vlan's. Vlan 1 is to the network. Vlan 20 is going to be for wireless access to the internet. How do I configure the switch/router so that Vlan 20 only connects to the internet and not the network? I will later want to have a 2nd SSID that I want to connect to both the internet and network.
