Ethernet Deployment In Metropolitan Areas To Access Networks

Jun 19, 2011

I hear a lot these days about ethernet deployment in metropolitan areas as access networks. Does this mean that there would be one big optical ethernet LAN (or MAN if you prefer) with fiber to the home connected by switches? Wouldn't this lead to massive spanning trees in large cities? One bad,configuration in the network would affect the whole network.Will all IP traffic have to travel to the core even if it is destined for an intra-MAN destination? I cannot imagine that a ARP broadcast in a large MAN is feasible.

Cisco WAN :: ASR1000 - Encryption Over Metropolitan Optical Ethernet

Mar 1, 2012

We're installing ASR1000 series (ASR1001 and ASR1006) routers on a new WAN and have a requirement to enrypt the traffic between the EIGRP neighbors.  Each ASR will be connected to the MOE with a gig interface and we will be using L3 on the interfaces with EIGRP as the routing protocol. We have advipservices-k9 IOS-XE
The ASR1006 is our datacenter WAN router and all remote sites have the ASR1001s.  The ASR1006 WAN interface will be configured with L3 subinterfaces, one to each remote location, using a /30 mask.
What is the best method to encrypt the traffic between the ASR1006 WAN interface and the remote ASR1001 WAN interface?

Cisco Wireless :: E4200 - Small Business / Wi-Fi Access In Public Areas

Oct 5, 2011

We are looking into the possibility of putting in some public wireless access in the public areas of our organization. Its a fairly small building in terms of public access and it needs to span 3 rooms in total. We have a spare BT line into the building - ADSL 2+ - and so will utilize that instead of putting them on our network. We would like to run some router based content filtering on the router - but would use open dns if this isn't possible.I could do to find a good wireless router that will cover the 3 areas . Its not a large budget project as there isn't going to be very highly utilized. We are looking Cisco kit - and have drawn up a few options. Initially we were going to go with the 1140's - but these are access points and as per my understanding aren't going to work with the phone line - as it needs to be a wireless router.
The next area was the Linksys E series (E4200) - they do look really good, and they have the content filtering which we like. What the power and range of the E series is? The only issue we might have is its a fairly old building and so some of the walls are pretty thick - one of which is wooden lined.It has the 3x3 mimo antennas and so guess it would provide some pretty good range/power. If the hardware is cheap enough then we may be able to setup the routers in repeater mode - however I'm not sure if the home devices can work that way? - I think max would be £300 - but that will be decided when I have some better numbers.

Black Areas Appear Over RDP?

Aug 22, 2011

An issue that we have run into is that on some of the machines, black areas appear over the screen at random times.These black areas disappear when the users mouse over and return when the mouse is moved back. The areas are usually small (about 30 pixels wide) and we have had to log the users off and on again.The machines that users are using are Thin Clients (HP and Wyse) and it seems to happen when certain programs are in use (Sage).

Cisco Wireless :: 1140 Access Point Channel Deployment

Apr 12, 2012

We are starting to greatly increase our access point density throughout our floors and I am wondering if we are using the correct channel assignments. We are using LAP 1140's and 3500's. We have some locations that have have anywhere from 4 to 9 floors in one location. These are consecutive floors that have 8 to 11 APs per floor. There are also other businesses in these buildings that use wireless as well. We use 802.11a/n and 802.11b/g/n. Right now the channels are set to the default, (36, 40, 44, 48, 52, 56, 60, 64, 149, 153, 157, 161 for 802.11a) and (1, 6, 11 for 802.11b/g/n). I was wondering that since we are increasing our density whether we should enable other 802.11b/g/n channels outside of 1,6,11. I know the other channels can overlap but with correct placement I am wondering if it would improve our wireless coverage since we wouldn't have 8 to 11 APs fighting for only 3 channels. Any experience with enabling other 802.11b/g/n channels?

Combining Ethernet And Wifi Networks

Dec 13, 2012

I'd like to know if there is some easy-ish way to combine wifi and ethernet in a network.Since a picture says a thousand words, here's what I want to achieve:I use the desktop computer as a file and media server using windows home group.I have the laptop running windows 7 connected to the TV.So far I've been using just wifi, but when I try to stream movies from my desktop to the laptop I get freezes and glitches.I can't connect both my desktop and laptop wired to the ADSL router, since it's behind a wall I'm not allowed to drill trough.I have a spare network switch and cables, so I was thinking I could connect the ethernet adapters on the desktop and laptop together trough the switch, I'm just not sure how to configure the computers.

Cisco Firewall :: 2911 Difference Between The Firewall Areas

Oct 4, 2011

I recently inherited a Cisco 2911, that appears to have had Firewall rules imported into Externally Defined Rules. ACL's are currently allowing/disallowing traffic. However, there are no firewall rules configured. To meet compliance we need to have Packet Lavel Inspection (Firewalled) rules. There are two areas in the router, under ACL area, and under Security. What is the difference between these two Firewall areas?Are both areas providing packet level inspection?Can I build Firewall rules (within the Security area) to replace the ACL's?

I have two separate network with their own internet access as shown below I want to keep all setting of the left network unchanged. I can change the IPs and setting of the right side network.I want to be able to access all devices of the two network from my computer but in the same time the two network work as usual with no problems ( the same when they are sperate).One option is to set the LAN of modem 2 to and connect one of the LAN port to LAN port of the Mkrotik router. Set the WAN of my private home router as

Cisco :: No DR / BDR Concept In EIGRP Multi-access Networks?

Jul 8, 2012

Why is there no DR/BDR concept in EIGRP multiaccess networks? If the purpose of a DR/BDR is to limit excess traffic when there is a change in the topology, why isn't there one in EIGRP? I understand that DR/BDR share LSAs and not routes but the concept is still the same: there is a change in the topology and the change gets flooded to all neighbors, those neighbors in turn flood it to their neighbors on the multiaccess network thus causing excess traffic.

Cisco VPN :: ASA 5520 8.2(3) - Allow Remote Clients To Access Other Networks

Oct 24, 2012

I have an ASA 5520 8.2(3) and allowing my remote client-to-site-vpn clients to access resources directly connected to my ASA on separate lower security interfaces (not the outside) besides just clients on my internal networks.  Someone mentioned to me configuring 'VPN on a stick' however from what I've read this seems to be only applicable when it comes to split-tunneling back out the outside interface (could be off on that).  Is this possible on other lower security interfaces as well, and if so what would a mock config that accomplishes that look like (acl's, nat, etc)?  Also, if I want internal users to be able to connect to these remote clients once they are active, are there any nat statements necessary (such as nonatting them) or are the vpn clients just seen as internal clients from the rest of the internal network's standpoint by default?

ASUS Netbook Cannot Connect To Wireless Networks - Limited Access

Oct 19, 2012

I have: ASUS Netbook with Windows 7 Starter.

As of last night, I cannot connect to any of the wireless networks I use every day (my personal home network or my school's WPA2).

The signal strength is very good, but it says "Limited Access" next to the network name. Apparently "Limited" means "No" because I am not connected. Here's what happened:Lavasoft Ad-Aware was blocking a site that I needed to access. I haven't used Ad-Aware in months, and it did not even appear to be running. So uninstalled it with Add/Remove programs in the control panel. BUT, mid-way through the uninstallation, I got a blue screen and my computer restarted. When my computer booted back up, I could no longer connect to my home's wireless. I'm at school now and I cannot connect here either. Ad-aware is gone from the add/remove programs list, but there is still an Ad-Aware folder in Program Files. The folder still has a bunch of stuff in it, including adaware.exe. I dont see an uninstaller (but i havent really investigated that yet). so now i can't connect to any network. Here's What I've TriedRan troubleshooter. Useless. Turned off my netbook's wireless. turned it back on. Device manager says my Network Adapters are working fine. No yellow or red icons next to them. also tried resetting stuff with the command prompt. something about winsock and netsh. I don't know what I was doing though. just following instructions from other people on yahoo answers when i googled the problem.

TP-Link WR740N Router / Unnecessary Home Networks With No Internet Access?

Aug 3, 2012

I've been having this issue for quite some time on my Windows 7 SP3 x64 machine. It's a desktop, connected via ethernet to a TP-Link WR740N router, that also provides wireless coverage. My ISP is a local one (the country is Latvia), and it offers a decent 100 MBps up/down optical fiber internet service. Now for the problem - there is only one home network on my computer, that seems to work, and that is 'Network 2'. Whenever I have to reboot the router for whatever reason, it attempts to reconnect, but sometimes reconnects to a 'Network 3' and once even to a 'Network 4' and 'Network 5'. None of these other networks have internet access. I tried to run the diagnostics tool on the issue, and usually it told me that there's a problem with the default gateway. Additionally, twice I've had the issue of the computer completely freezing when connected to one of the Internet-less networks (eg 'Network 3'), and trying to disable the network adapter, forcing a restart that consequently caused a fail boot - from there on I had to use System Restore to actually get my PC to function.

The way I've been fixing it, apart from random rebooting, reconnecting, and hoping for the best (that it decides it wants 'Network 2'), is by putting in the Resource Mini CD that came with my router, and running the Wizard for the WR740N router. It has 4 steps, the 2nd of which is 'Installing the router' (configuring the network adapter), at which point, my internet starts to work (always connects to 'Network 2'). If, I however, decide to continue this process to the step 'Configure router', and attempt to set up my wireless connection, it will begin to reset itself, and once again connect to 'Network 3', leaving me without internet access.

Cisco VPN :: ASA 5510s / Remote VPN Users Need To Access Networks Connected By Static VPN

Oct 23, 2012

I have five (5) sites all connected via static VPN tunnels.  They are all using Cisco ASA 5510s running 8.4(4)1. Any internal IP on each site can ping any IP on a remote site, because of the static VPN tunnels.  I have the external IP (routeable) addresses connecting to each other.

Site A: /24
Site B: /24
Site C: /24
Site D: /24
Site E: /20

I have remote users who connect using Cisco AnyConnect 3.1 to Site E.  They get a static IP within the /24 subnet (vpnpool00) and can access anything in the /20 subnet. So far, so good.No management wants users to access devices within the other sites, specifically Site A using teh same AnyConnect connection.  In other words, they get an Ip address of say, and now need to access a server on Site A's subnet or have checked my NAT statements and they appear to allow this, but so far when I do a ping I get the following:  Routing failed to locate next hop for ICMP from outside: to inside: What am I missing?  Is there a NAT statement that is wrong, or an access-list statement or possibly a static route?

Cisco Switches :: ESW-520 / Setting Up Two Separate Networks With Access To Shared Resources?

Jan 19, 2013

We have a two separate businesses in the same building who will both need access to shared resources and the same internet connection. They will need to remain on separate subnets and cannot communicate directly to each other. The current switch is a Cisco ESW-520-48P and we are looking at purchasing an SG-300-20P for the new business moving in. Heres how we envisage setting it up:
ESW-520 will host Company A's network. Workstations, servers etcSG-300 will have two VLANS. VLAN1 will host all Company B's network. Workstations, servers etc. VLAN2 will host the shared resources such as printers. The internet gateway is a UNIX based system with 3 NICS. 2 NICS are taken up by ADSL connections while the other NIC is the LAN, which would connect to VLAN2 on the SG-300. We would like to define which ADSL connection to route through depending on which subnet traffic is originating. The ESW-520 will need access to the shared resources and internet gateway on VLAN2 on the SG-300.

Linksys Wireless Router :: How To Link Two Networks WRT54GL - Unable To Access Printer

Sep 18, 2011

I just bought a WRT54GL which is working perfectly. I needed it to extend my home network for my kids (I have not a very fast internet connection and my kids are eating all of it... With the WRT54GL I can choose how much they can have. So my own network has a netgear modem and a netgear wifi access point which is  in this network : 192.168.0.x.

This network is not blocked in any way (just password protected). For my kids network, the WRT54GL gives addresses in this network : 192.168.1.x and is limited in speed. Everything is perfect, I have internet connection on both of my network, There is just the problem that I cannot access my printers, my servers, my computers.... that are on the 192.168.0.x network from 192.168.1.x. Is there a solution ? I already tried to force the WRT54GL to go to 192.168.0.x network but no more connection. Should I "bridge" the two networks ? How can I do it ?
