Cisco Wireless :: 2504 - Guest Network Completely Isolated From LAN
Jan 28, 2013I recently got my Cisco wireless system working a few days ago and am back with a guest network. Our wireless system includes one 2504 controller and 2 2602i access points. So, I want a wireless guest network completely isolated from the LAN.
Here is what I have done.
I have created a new internal network and assigned 192.168.2.1 to an unused port on the firewall and 2.2 to a new controller interface with vlan 10. I can ping both 2.1 and 2.2 from the firewall and the controller. Basic network connectivity is working. The DHCP server is setup on this same firewall and configured only for this port. This address is referenced in the controllers interface.
A new w lan was setup and enabled. The proper interface group was selected on the w lan. I have left the default layer2 security.
As far as AAA servers tab in this wlan, this is where I am a little confused. I wish to just have a single log in for this guest network. I wasn't sure what to do so I went over to the Security tab and created a "local net users" account. I do not know how to reference the use of this under wlan, security, aaa servers. Should I check the box that says "local eap authentication"?? If so, I don't have a profile name in the drop down. What I'm looking for is the username/password to be stored locally on the controller itself since there will be only 1 account.
Under wlan, advanced tab, I do not have "Allow AAA override" checked. Should I?
Lastly, when I try to connect the client, it is not pulling a dhcp address. I wasn't sure if authentication was required before dhcp or the other way around so I'm not sure what to trouble shoot first, authentication or dhcp.
Connecting To Isolated Networks With The Same Network Id
Nov 24, 2011Basically, the issue I am having is we have a class b network ID of 172.16. We had a new phone system installed last year which needed to be on an isolated network as our switches do not have QoS on them. Plus they are quite bad...
Some genius decided to use the same network ID on the new phone system as our current network but they are totally isolated networks.
This is where my laziness comes into play... We use a laptop connected to the phone system's network to connect to configure the phones etc but I would like to do this at my desk. So what I have done is configured a wireless access point on the phone systems network so I can connect to it on my laptop to theoretically make changes to the phone system on my PC, but also staying connected to our network for obvious reasons... I do have some networking knowledge, and I am assuming the routes are going to be completely wrong because of the same network ID issue not allowing me to connect to the phone system on my laptop. But I am not sure if I can add a static route to resolve this.

Recover Forgotten Wireless Network Key?
Nov 6, 2011I'm using Windows 7 Ultimate. Now I created a Wireless Network from my Router, but I forgot the password. It is WEP encryption. The only way I can connect to the wireless network is if I disable the security in my router config.

View 1 Replies View RelatedCisco Switching/Routing :: 3750X - Isolated SVI For Management
Jan 18, 2012I have a stack of 3750-X that are used to both switch traffic inside V LAN and also to route a couple of WAN ranges from our up link provider to the DMZ v LAN.Now I'd like to have a SVI Vlan1 with an IP in the "management v LAN", but I'd like that SVI not to be rout able.
More exactly :
- no traffic should ever exit that interface that's not the generated by the router itself (ssh/snmp/...)
- no incoming traffic on that interface should be forwarded anywhere
- I'd also like to have a different default gw to be used by traffic generated by the switch itself. (for eg, ssh traffic coming from any another sub net like 10.2.0.0/24 to the switch SVI Vlan1 ip 10.1.0.1/24 should be routed back through the Vlan1 gw and not through out up link ptp gateway)
I think I can achieve the first two with ACLs on the SVI. But not sure about the last one ...
D-Link DAP-1522 :: Ethernet Ports Isolated In Bridge Mode
Jun 13, 2012I have a DAP-1522 in my den that I am connecting as a bridge to a Netgear WNDR3800 that in turn is connected to a cable modem in my living room. I have multiple PC's connected to the DAP-1522 via the Ethernet Ports. All the Ethernet connected PC's are getting IP addresses from my Netgear WNDR3800 via DHCP and can access the Internet fine. The weird thing is the PC's connected to the DAP-1522 through the Ethernet ports can't see each other - they are isolated from each other. I can see the DAP-1522 hard wired PC's from a laptop connected wirelessly through the Netgear WNDR3800 but the PC's wired to the DAP-1522 can't see each or communicate to each other via IP, though they can communicate to anything else on the Netgear WNDR3800 wireless network or Internet.Only the PC's connected to the DAP-1522 via the Ethernet ports are isolated from each other. Very strange. This is a problem because I have a NAS device I want to connect to the DAP-1522 that will be shared by the PCs in my den. I do software development and want access between the PC's and NAS device at Ethernet Gigabit speed. I am using default configurations for the DAP-1522. It appears that firmware for the bridging function if funky. I am on firmware version 1.41. The hardware release is A1.Not sure if it is an issue with the DAP-1522 or the Netgear WNDR3800.

May 30, 2012I have an ASA that houses 11 VLANs, and I am trying to add a 12th.One of the VLANs is for PCs that have internet only access.The new VLAN will be similar, but for multifunction printers only.VLAN 99 is for internet only and works fine, I can ping the gateway of 10.99.3.33 from any PC in that VLAN.I am creating VLAN 98, modeling it after VLAN 99, and I cannot get a PC in the vlan to ping the gateway of10.98.3.17.Both switch and ASA show the new VLAN 98 as UP, switchport is UP/UP.I have deleted and recreated VLAN 98 a few times, but I cannot get a PC VLAN 98 connectivity.Once it is working on the core switch, I will add it to the trunk to the IDS switches. VTP is not in use, everything is manual. [code]

May 6, 2012My core switch is a 6509-e and my IDF closets have 3750's.I have a couple of vlans currently setup, that can communicate with each other.VTP is setup Client/Server where as my core is Server, all IDF's are Client.
What i'm trying to do is create an isolated VLAN. I want to setup a DHCP scope and use helper address. When i plug in a client to that VLAN, i want it to get an IP, but not have any other network access.
Is this possible to do without switching to Transparent mode? If not - what reprocussions will i see by switching to transparent mode?
Cisco Switching/Routing :: Private Vlan / Etherchannel And Isolated Trunk On Nexus 5010
Feb 9, 2011I'm not sure if I'm missing something basic here however i though that I'd ask the question. I recieved a request from a client who is trying to seperate traffic out of a IBM P780 - one set of VIO servers/clients (Prod) is tagged with vlan x going out LAG 1 and another set of VIO server/clients (Test) is tagged with vlan y and z going out LAG 2. The problem is that the management subnet for these devices is on one subnet.
The infrastructure is the host device is trunked via LACP etherchannel to Nexus 2148TP(5010) which than connects to the distribution layer being a Catalyst 6504 VSS. I have tried many things today, however I feel that the correct solution to get this working is to use an Isolated trunk (as the host device does not have private vlan functionality) even though there is no requirement for hosts to be segregated. I have configured:
1. Private vlan mapping on the SVI;
2. Primary vlan and association, and isolated vlan on Distribution (6504 VSS) and Access Layer (5010/2148)
3. All Vlans are trunked between switches
4. Private vlan isolated trunk and host mappings on the port-channel interface to the host (P780).
I haven't had any luck. What I am seeing is as soon as I configure the Primary vlan on the Nexus 5010 (v5.2) (vlan y | private-vlan primary), this vlan (y) does not forward on any trunk on the Nexus 5010 switch, even without any other private vlan configuration. I believe this may be the cause to most of the issues I am having. Has any one else experienced this behaviour. Also, I haven't had a lot of experience with Private Vlans so I might be missing some fundamentals with this configuration.

Nov 15, 2012I have an Acer 7750G, running Windows 7,connected to our home network using a Dynex router. At the moment this is the only laptop in the house that is having problems with connectivity. Starting yesterday, it only connects intermittently. When I run diagnostics, it says the following problems have been fixed but it either solves the problem for a few minutes only or not at all: "Problem with wireless adapter or access point" or "Default gateway is not available".
IPV6 connectivity also shows 'no internet access' and sometimes IPV4 reports no internet. I've unplugged and rebooted the modem and router a few times but that hasn't solved the problem.
Edit: I ran troubleshoot again, and it says the following issue is not fixed: "Wireless Network Connection 2 does not have a valid IP configuration".

Jul 8, 2012I recently bought a Linksys E1200 router. During the set-up, while setting security up, we stupidly by-passed right by the WEP key it generated. This then booted us off the connection since we changed it, and since we didn't get the WEP key, we no longer can enter it in and connect to it. We tried entering in the default IP using another connection but it will not work.

View 1 Replies View RelatedAsus RT-N16 - Couldn't Recover My Password?
Apr 4, 2013I couldn't recover my password so I just created a new account.I just recently bought the ASUS RT-N16 since I switched to a different ISP that provided only a modem.
The problem: Some computers in the house will connect no problem to the network and without trouble. Other computers will be able to connect to the network but it will be restricted. When you go to the internet browser it shows an Asus logo and says: "the cable for ethernet is not plugged in". All the computers are wireless and in fact I am writing this while connected to the RT-N16 (wirelessly). Also, sometimes a computer will boot, I will go into the browser, it will show me that message, I unplug the RT-N16, plug it back in and the internet works again. This happens everyday.
P.S. I would also like to note that I tried connecting to the internet network with a nexus and it showed me the same error while I tried connecting with a samsung galaxy S2 and everything worked just fine. Also we got like 5 computers at home and I'd say 1 computer always connects fine, some don't connect regardless of whether you restart the router or not and some computers work only when you restart the router so I have very mixed feelings about this one...

I now can't log on to any account including the administrator.I don't have the recovery disk. MS suggests a parallel installation of XP to provide access to the files on the disk. I can do that with any Linux CD. I don't have any data I want to recover. That was all stripped off before I got the PC. I do want to keep all the applications. If I reinstall XP, I will loose all the applications. I now know I can only logon to the administrator account if the PC is connected to the domain server. If I can restore the domain name, I can log on to the PC again.Where is the domain / group info kept and in what format?Is there a way of using a Linux CD to manually edit the XP files to restore / add a domain??
