Routers / Switches :: How To Secure Network Connections
Oct 2, 2011
My itty bitty manual just shows on how to hook up my router via cable modem...nothing on how to secure it. I go into setup of the router and see where one can add info but am at a loss what to enter. I tried, merely by guessing, applied the info, and screwed up my networking. I couldn't even get into my router to revert back, cause i couldn't get on line...finally i reset manually my router and all is well again, except when i see a list of nearby network users, mine is the only one that says unsecured.

2 routers in series, is one more secure. I recently asked about setting up two routers in series as routers, one wireless one not. It was my understanding that the computers on the second router would not be visible to computers on the first router, the wireless one. My assumption was that this would make it more difficult for someone who got access to the wireless router to also access those computers on the second router.

I'm not sure about my title, it;'s the best I could come up with. I have approximately 7 computers, two iPhone, and iPad, wireless printers and a network attached storage. Most are connected over via wifi, the exceptions being one pc, the nas and a printer. I plan to add six more devices plus some ip cams. The way the router or network is configured whenever a guest connects to our wifi they can "see" our computers. I haven't been able to tell if they can see the files or just the name of the computer. Question 1: How can I tell if the guests are able to access the data on our computers or networked drive? Question 2: If I add a switch will I need to do anything special with regard to security?

We are planning 3 Internet Connections into our building. 1 will be for actual Internet traffic, 2nd for Voip phone system, and 3rd for internal network for Active Directory...etc. Oh the AD servers are controlled by another business so technically this line is still considered and outside line and is a T1. What I need to know is how best to make this all work so that our internet phones use the VOIP system, computers can log into the domain and access that network but use the Internet network for actual internet traffic? We were considering a series of managed switches and creating 3 VLAN's but I'm thinking we instead need a new router that all 3 networks connect to and dishes out DHCP to computers and phonesn example network is below.192.168.1.x ----> Internet (all computers use for internet traffic)72.10.10.x ----> VOIP (All physical and software phones use this network)10.10.10.x -----> Connection to external company that controls our network and has domain controllers, mainframe...etc.

Does the Host file allow connections to your computer?Although I have placed some server names into the host file, Wallwatcher 5.0 is indicating that those servers have made connections. This didn't seem to be a problem before I took some online advice to add servers to my host file. I use iptables on a WNDR3700 router with DD-WRT firmware. In the iptable rules I've also blocked these servers. One example is cnbc7.net and a couple of U.S. Akamai servers.

Had laptop connecting wirelessly perfect with no problems. We then added another laptop and PSP 3 to the house hold. Any of the 3 devices will connect to the internet via wireless but ONLY one at a time. If you are connected with one and turn on one of the others it will kick the one off that you were on and only 1 device can use wireless at a time?

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.

I have a D-Link DIR -655 wireless router connected to my Time Warner Cable modem upstairs. Downstairs I have a PS3, Wii, Logitech Revue and a HP laptop. I get low signal strength downstairs(many walls) and would like to run an Ethernet cable downstairs to my devices. What hardware do I need downstairs to hard wire those devices? Not sure if router or switch and what kind. Do I need to make any changes to my existing D-Link wireless router? I want to keep the wireless available for cell phones and the HP laptop.

I am currently playing Football manager 2011 with a friend via a network game. The game will work perfectly if I connect my Laptop to the modem directly and bypass the Wireless. However if I try to play the game while connected to the wireless then my friend is unable to connect to the game. This is becoming an issue as for me to be able to play the game I have to turn the wireless off which is getting on the nerves of other family members

I have followed directions and forwarded the two ports to the local machine. I looked in the router setup to find my current public ip address from Comcast say its 98.221.99.99. If I am on the same network as the machine that is receiving the port forwards, and I type http:// 98.221.99.99 in a browser, the forwarding works fine.If I am external/not on the same network, typing http:// 98.221.99.99 in a browser times out. I have tried http:// 98.221.99.99:9000 too (9000 is the port I need forwarded) and that doesn work either.But, I do have remote management enabled for the router and if I am external/not on the same network and I enter http:// 98.221.99.99:8080 in a browser, I get the router login screen and can enter my user name and password and login to the router just fine.

I am able to access the internet. I am running Windows 7 on my laptop and have a wired connection between it and my intergrated router. The internet works fine, but it seems to think that I am not connected to the network. I'm not certain it realized that I even had a network, since when I try to activate media sharing it just gets stuck at "Identifying Network". The whole purpose of this is to be able to play music from my computer on my Xbox 360, alternative solutions for this goal would be good too.

I have been involved in the Networking of a museum with a set of "Show" computers which display video, and for this reason cannot have anti virus installed becuase of the performace hit, and also the risk of pop-ups on the videos. They do however need to be connected to the internet as some are interactive and allow people to send simple emails, and they all need to allow remote support when things go wrong.It seems the networking was not thought out very well initially, and there is a single wireless router which serves the staff and public on a secured wireless network, but also serves the "Show" machines via a wired connection from one of its ports, which then connects to a master switch which serves the show machines.Now the wired and wireless is on the same network, and everything shares the same IP subnet (192.168.1.xxx), and this is not a good situation in terms of the securuty of the show machines on the wired network. So I need to work out a way to totally separate the wireless network (which will be very prone to people opening viruses in their emails etc), from the wired network (which will be the show machines which wont be touched by anyone).
I want to achieve this in the simplest and easiest way, and have been reading about the possibility of setting up a second wired router behind the current wireless one, with a different subnet IP address, to which the "Show" machines could be connected. The WAN port on this second router would connect to a LAN port on the wireless router, and thus the show machines could get their internet, but separated from the dangerous wireless network.Does this sound like a sensible start? Will the fact that the wired router (and show machines) are on a completely different subnet to the wireless router (and wireless devices), mean that the wired network will be protected? Or do I need to do more? And is this likely to work?
