So, using a standard off the shelf UNMANAGED gigabit switch (just a cheapie), I have a scenario that I need to know about before I go and buy a whole lot of equipment.Ok so let's start off and say it's a perfect world and the workstations connect at a full 100 Mb/s and the server connects at 1000 Mb/s.So I'm looking at having say, four or five workstations connected to the gigabit switch (at 100Mb/s) and also a gigabit connection from the switch to the server. In this scenario, taking into account everything I've said above, would each of the workstations get a full 100 Mb/s to the server, or would everything be limited to 100 Mb/s total? I could see potential for the server to only talk to one of the workstations at a time and only at 100 Mb/s, but hopefully all four could communicate to the server simultaneously.
I think it was three or so years ago that I first went shopping for a top-notch gigabit wireless router/switch for home. I wanted VPN tunneling or at least pass-through, gigabit switching on the 4 ports, wireless n (preferably dual band) and the works. I wanted it to be fast (using a high speed business- class connection at home serving content back to my office at work) and I wanted it to be reliable.
So, I got what seemed to be the cream of the crop at the time, a Linksys WRVS4400N. If you know anything about this model, you know what a disaster it turned out to be - garbage firmware, constant reboots, terrible support, none of the features worked.
I fiddled with it for over a year, including one warranty replacement, before giving up, throwing it in the trash (literally) and thinking, maybe I'll try a "gamer" unit... so I got a Dlink 4500 with the crappy OLED display. It was faster. Most of the advertised features work. But, it wasn't reliable - lots of software bugs, each new firmware would break something new, terrible support, and almost daily power cycling because it would freeze.
That's because the Netgear WNDR3700 had shown up and was going to be the cat's meow. It was fast, seemed to run cool versus the previous two, had a reasonably fast UI and was bonafide dual band. Looked great. But as before... I made the mistake of putting it on autopilot with firmware updates, and the factory firmware was replaced by a series of increasingly unstable builds. Now, several of the features I bought it for don't work, the 5GHz band is dying, support is terrible, recent FW seems to have broken VPN passthrough and yet again I go online and see a five star router now turning into a 2.5 star clunker.
Are gigabit consumer routers uniformly junk? They all launch with great expectations, then fall flat on their face within 12 months, their fall from grace bracketed by atrocious support on one side and terrible firmware developers on the other. I've tried three top models from three of the largest manufacturers over the last four years and have had the same experience each time. Meanwhile, I go back to my $40 WRT54G and it just works.
My question: if I'm looking for something fast, reliable and not prone to getting in my way, do I need to simply call it a day and go up a few rungs on the ladder? Maybe a Sonicwall TZ2xx unit? (I've installed these in field offices for years, they work great.) Or a used Cisco Aironet plus a switch? Photo printers occasionally aside, I've never had so many problems with "premium" consumer electronics products as I do with gigabit wireless routers....
I upgraded my fireware and now the router don't do anything, I can't even login into it using [URL] which a hard wired connection. How do I get logged into the router to try and put the old version of firmware back on it?
How can I tell if the ATT Data Service on my iPad is going through an ATT Carrier Grade NAT router or proxy server? Why I can't tell.
1. iPad does not have an interface that shows the assigned address on the Data Connecton or access to any terminal commands.
2. The reported ATT (Cingular) address is 166.147.103.208 if you use a What-Is-My-IP type of service. On a Verizon (not ATT) iPad I can ping all the way back to the iPad and turning the iPad off stopped the Ping Response . . . but there is no answer when I ping the ATT iPad 166.147.103.208 and Trace Route to the iPad stops answering at the border of the ATT network.
3. If I make a page request on an IIS web server from the ATT iPad, the web server logs 166.147.103.208 (see above) as the source address and logs the iPad as the source device, but 166.147.103.208 could still be an ATT proxy, not the iPad because some NAT routers change the source IP address to themselves.
We want to use an ATT Hotspot as the the permanent always-on home internet service where there is no other option (except satellite). We need dynamic DNS at the home, and that requires a routable public address on the ATT-hotspot. We are guessing the iPad and HotSpot would be using the same ATT network.So how can I tell if the iPad has an ATT address that can be reached from the internet (no proxy's or carrier grade NAT routers)
Is there an easy way to detect NAT devices - specifically home wireless routers like those from NetGear or D-Link or Linksys - on my network? I've shut down the ones that are easy to find by looking at the hostnames on the DHCP server, walking around with my phone and capturing the MAC address of the AP then finding a matching MAC address one number higher or lower. But there are still more out there evading me and I need to shut them down.I've read about a method using SFlow/Netflow, but my old Cisco 3750 and 2950 switches don't support that. I've read about a plugin for a Linux based firewall, but I use a Cisco ASA.
I'm setting up a large rambler house with a large footprint, and the only broadband connections are at opposing points of the house. Right now, I'm using two Linksys WRT54GS routers running Tomato in a WDS setup. A router, positioned in the middle point of the house, acts as a wireless access point so that the computer on the far end of the house can pickup the wireless signal. (One WRT54GS on its own doesn't have the power to go all the way across the house.)
I would like simplify things with a single, hi-power, hi-speed router at one end of the house. I know I can get better speeds with Draft N routers, but I need more signal strength as well. Are there any products currently available that can perform much better than my WRT54GS routers right now?
I need to go about 125 feet, through a number of walls.
We are deploying ACS 5.2 to replace our ACS 4.2 in production. I have two wireless networks setup as WPA2-Enterprise. One points at the ACS 4.2 and the other at the ACS 5.2. Both use the same SSL certificate with the same CN. Both authenticate Windows 7 clients. However, Windows 8 CP will only authenticate to the ACS 4.2 and not to ACS 5.2. The error it gives is:
11051 Radius packet contains invalid state attribute
It also shows no authentication method (most of the time).
Occasionally, I get a request that actually shows an authentication method of PEAP (EAP-MSCHAPv2) which is what it should be. On those requests, I get error:
24444 Active Directory operation has failed because of an unspecified error in the ACS.
Both ACs 4.2 and ACS 5.2 are pointed at the same Windows AD source.
We are using D-Link DSS-16+ Ethernet Hub Switch and the broadband modem (1Mbps) is directly connected to the hub and it's currently working.Now we have a D-Link Ethernet Router DIR-100 (got it free when we bought the PCs) and an extra broadband modem (from the our home) and I was planning to add it in our shop. I will still be using our current network connection, but I was planning to add the router and that extra modem for the server. I want to use the modems separately; the first one for the 14 computers and the extra one for the server. how to config them?
I'm planning to build a home network total of 11 computers including a server the other 10 units as client..i have a wireless router with 4 ports & a 8 port switch,i have read it before that i can connect my switch to 1 of the ports of my router and it can use my internet connections. anyways i was wondering if i can still use the other ports of my router as i would like to connect my server directly to the router and not on the switch so that i will be able to connect all the 11 units on my network, and also control it through my server using a client software.
Its just a basic question, I have a FS726T switch, and wanted to know how the clan thing should work.
Group A are ports 1-8 Group B are ports 9-16 Group C are ports 17-24
Internet is on port 26
I want each group seperate so 3 vlans... but does port 26 need to be in all 3 vlans for.them to receive internet? Is it possible to have 1 port in 3 vlans?
Would that keep them from seeing each other and still access the internet?
I have setup an Asus RT n16 with 3 computers that support gigabit ethernet and a media server on one floor. On the other floor I have set up a fast ethernet switch (connected to my asus router) which is connected to several fast ethernet enabled computers.
Would the fast ethernet devices slow down the entire gigabit networking to 100mbps connections on my floor - similar to how a wireless n network running at 300mpbs must slow down to 54mbps when a wireless g device is connected to it?
on my home network I currently only run an Airlink101 AR675W router. We have a couple issues with this. The router for one is in my basement and there are points in my house that have low signal strength, especially upstairs in the far corners of the home. Second is I am currently running my home PC as a media center but it is set-up wirlessly so streaming is clunky and jittery. Also on this network is 3 X-box's wired, a PS3 running wirless, 2 PC's wired in, 2 wirless laptops and the afore mentioned wirless PC. A lot of weight for the network. What I want to do is move the router upstairs, hardwire it into my wireless PC (the one doing the streaming) and connect a second router (an identical make and model I am buying this weekend) downstairs which will be basically used as an "expansion" of the wirless and a switch for the hardwired devices downstairs. would this be better than simply moving the wirless router upstairs (hardwiring my PC) and putting a 5 or 8 port switch in downstairs for the X-box's and 2 wired PC's there?
I got a retired Zyxel Zywall USG200 from work. Its working just subs ran out. Was thinking of putting it on my home network, any reason not to? I'm a sys admin, not network engineer, so while I'm capable I'm not an ace with this type of equipment.. Which is why I want to mess with it. I'm currently RTFM and it seems pretty straight forward. If it seems like a viable piece of equipment I'd like to use it full time. How bad can I break the internets and subject myself to the wrath of my wife's downed internet connection =D if I plug it in between modem and the switch?
We have the following architecture for Internet access:
LAN ---- CISCO-CHASSIS----FIREWALL-----INTERNET
My concern is about PAT, for LAN users Internet access: I would like that PAT is performed by Cisco chassis(in my case, a C4500), not by firewall (which means: local IP addresses for flows from LAN to Internet are all natted with the same public IP address).Are there some drawbacks to this design? I guess there is no problem for classical flows, but what about flows with specific comportment (such as FTP) on Cisco routers?
I'm currently running 8.3(2) on my 5520s in an active/standby config. The 5520s have the 2GB RAM upgrade and 256MB flash card. Are there any CPU limitations in going to 8.4? I read the release notes but didn't seen anything about CPU. I heard through the grapevine that a 64-bit processor may be needed. We currently have the Pentium 4 Celeron 2000 MHz CPU.
I'm trying to use a 5520 to test something but the bandwidth seems pretty low for the product I'm testing over it. Can anyone tell me if there is a bandwidth limitation by default? I'm seeing 1.5mb/s average with spikes to 6mb/s or so. On the ASA5550 I was seeing usage up to 80mb/s.
I am experimenting with a Cisco 871 router. The router has 4 LAN ports and 1WAN port.What are the limitations wrt to the LAN ports when it comes to routing. Is the WAN port the only port that supports routing?
I've setup a Cisco Secure ACS server 5.1 in VMware ESXi everything seems to be working fine, however under the options for Policy Elements > Authorization and Permissions > Device Administration > Command Sets there is a command called "DenyAllCommands" that was there when i first installed the ACS. Is there any way to remove this? When I try to remove it i get an error that thats it can't be removed or modified. I'm writing a report on the Cisco ACS for university, if this is a limitation of the evaluation licence I will need to reference it. If this is a limitation and provide a link to a cisco page that confirms this.
......................Computer 3 Router 1 points to a VPNRouter 2 access to the internetComputer 3 needs to access router 1 (VPN). Both Computer 2 and 3 are in a different room than computer 1, and router 1. Computer 2 is networked via cat5e to router 2.Is is possible to have Computer 2 and 3 share the cat5e, yet access different routers?
I recently got a Static IP from my service provider, I'm working from home & configured a FTP server in my PC.
I have to transfer huge files say around 40 GB of data as I'm a Multimedia professional. I was using my web server, before for file transfers but there are lot of limitations to huge transfers.
My client, who is downloading using my Local Server says, it takes 3 mins to download a 9 Mb file, which took 17 sec before, when it was done with the webserver.
Does this have anything to do with my Internet connection speed as my speed is 1 - 2 Mbps. If not is there a possibility to increase my transfer speed ?
we have a RV082 and have the DMZ option enable for a range of IPs within the same subnet of WAN IP and this works great. I have another range of Public IPs from our ISP that is not in the same subnet of the WAN IP and do not see a way on the RV082 to include this 2nd bank of Public IPs in the DMZ. Our ISP internet feed plugs into the RV082 WAN port and we have a switch pulgged into the DMZ port of the RV082 that is used to connect the public devices in the current DMZ. Both banks of Public IPs from our ISP come over via the ISP internet feed plugged into the WAN Port. My question is, if I cannot configure a DMZ rule to allow this 2nd range of Public IPs to "travel" to the RV082 DMZ port.
We are looking into replacing our current Windows NLB configuration with a SLB solution as NLB creates some nasty multicast traffic.
We are currently curious about the limitations for running SLB without a dedicated ACE Module, will it handle line-rate speed (1 and 10 gbit) with SLB?
Does VSS introduce any limitations for SLB? Any other pitfalls/limitations we should be aware of?
Hardware info: 2x WS-C6509-E in VSS with VS-S720-10G (VS-F6K-PFC3C) running s72033-ipservicesk9_wan-mz.122-33.SXI7
I have found that there are only few configuration to the Cisco Aironet 600 OEAP. The settings are just for basic configuration for a wireless network when it is in autonomous mode.
A need for a Wireless LAN Controller to perform advance settings.
Also, there are no firmware available in Cisco. No upgrade/downgrade firmware avalaible for download.
What are the limitations of Net flow v9 support on the 7600 platform for the SR code releases?
I know that Flexible Net flow is only available on newer releases with some newer hardware. Flexible Net flow gives you the ability to provide full support for Netflow v9 as well as IPFIX.
However, the documentation indicates that Net flow v9 is still supported in the SR code. So I am just trying to find out what are the limitations in how Net flow v9 is implemented without "Flexible Net flow". The Cisco TAC was unable to provide me any documentation about this.
on ACSv5.2...are there any limitations on the number of users that can be imported via CSV file...i.e. will the ACS handle 250,000 internal users for example?
I have a ASA5505 that i have running asdm 6.4 on it and have tried setting up some DHCP scopes for the interfaces.I have the security plus key.I set up 4 interfaces all with different subnets and all with different DHCP being doled out by the firewall for the time being.Anyway, 3 of the 4 work.I have tried to change interfaces wondering if there was an issue with that phy device.I tried enableing the subnet that would not work first and it didnt matter still would not issue dhcp.the other 3 work fine.Is there a limitation to the amount of scopes that will issue dhcp for an asa5505 ?
Our company is planning to buy one of cisco ASA 55xx series.But there is still one question left about DHCP pool limitations.Here I found some information about licensing for DHCP on ASA 5505: [URL]In other words, we don't have any information about ASA 5510, which contains DCHP pool licensing.
