Cisco Security :: 3560G / NAC Setup / Authentication Not Working?

Nov 22, 2009

I am trying to get a NAC demo running and am having some issues with a Layer 2 OOB, Virtual GW configuration. Currently I have 3560G switches and would like to assign ports to a vlan based on user roles.
 
My Auth VLAN is 110 and maps to VLAN 11
Guest VLAN is 11      (172.16.1.0/24)
Employee VLAN is 1
NAS Mgmt VLAN is 20 - CAS is 10.10.20.5 (this ip is setup on both eth0 and eth1 per documentation for L2 OOB Virtual GW)
NAM Mgmt VLAN is 30 - CAM is 10.10.30.5
Untrusted (Eth1) switchport is setup as a trunk allowing only vlan 110 and has a native vlan 999 to blackhole traffic.
Trusted (Eth0) switchport is setup as a trunk allowing vlan 1, 11, 20 and has a native vlan 998 to blackhole traffic.

I also setup a Managed Subnet on the CAS with IP 172.16.1.254 and VLAN 110.Switchport controlled by NAC is access vlan 110. When a machine connects an snmp trap is sent to CAM and is forced into vlan 110. If I try to put the port in another vlan CAM puts it back to 110 immediately. This all seems to be working well.The machine connected to the port gets a DHCP address from VLAN 11. When I initiate traffic from this machine, everything is blocked. If I open a web browser I do not get an authentication page. I also installed CCA 4.1.10 on the machine but it does not find a discovery host and the Login option is grayed out. The only way to get this machine to send traffic is to add a filter for it and force it to the ALLOW option. I did setup a default web login page but I seem to be missing something to get authentication to work. I am running version 4.1.8 with a demo license. The host running CCA is Windows Vista.

Security / Firewalls :: Block Software With Password Bypass?

Sep 2, 2011

I am currently running a Windows 2003 Server Edition and I have an issue, we run a small piece of software for controlling the nights takings which connects to the tills database on the network.This piece of software is not password protected and is held in a safe, however it has come to our attention that an employee may have taken possession of a copy of this application and we need to block the application been run on the network.Now this is were it gets difficult, I know to stop the application I could just use the Software Restriction Policy with Hash Rules which would solve that. However the problem is that sometimes people WILL need to run this software on the network and not get blocked.These people may not have their own accounts etc so I am trying to workout a way that we can allow someone to bypass the software restriction policy with a password prompt, is this possible or is their another way around this issue?

Cisco Application :: ASA 5505 To Bypass WCCP For Specific Public IP Address

Jun 29, 2011

Currently using WCCP with squid for content filtering. One of our sites we connect to needs to see the connection coming from our public IP address, not the proxy server IP. I've created a acl in squid for direct lookup, but the website gets angry with the X-Forwarder-Header squid attaches to each packet. Is there a way in a cisco ASA 5505 to bypass wccp for a specific public ip address or url?

Cisco Switching/Routing :: 3560G - IOS DHCP AP Loosing IP Address

Nov 13, 2012

Not sure if this is a problem with the switch or the wireless AP connected to the switch, but I have a couple of 3560's, one is a 3560G and the other is a 3560, both have phones and wireless ap's connected to them.  The ap's on both of these switches continue to loose there ip address and thus disconnect from the controller.  This happens about once a week, but the odd thing is that the phones never loose there ip address.  All of my other 3560s and 3560g's that have AP's and phones connected are working fine.

Cisco Security :: ASA 8.4.1 Destination Address NAT?

Jul 15, 2012

i have a situation where i have a deployed asa5505 running 8.4.1.The client has an existing mail server that is located on their lan and has Port Nat's configured for the normal mail ports,  25,110,993,587 etc.
 
This works fine for mail inbound and for any user popping mail off the server externally or visiting the webmail interface from outside the network.However when users inside the LAN try to connect through the ASA back inbound to the IP on the External Interface of the ASA they are unable to do so.
 
One solution i came up with is Split DNS.   and well this works it rely's on the users not changing their dns servers.I was wondering if it's possible to do some sort of NAT that rewrites traffic destined for the above ports on the external IP to the Internal LAN Ip instead.

Cisco Security :: C3800 / Filter Traffic By Mac Address?

Jan 23, 2011

Is it possible to configure cisco router like C3800 or catalyst switches like C4500 or C2960  to filter traffic based on allowable mac addresses only? I would like only to allow those devices that belongs to the domain, meaning if a user connects a computer or any devices that concerns network which I have not allowed the mac addresses, it will be denied access to the network. However, any of the allowable devices could able to use any port of the switch, meaning I dont want to associate an allowable Mac Address to a physical port on the switch.

Cisco Security :: 5505 Outside Traffic Not Destined For Outside Address Showing Up

Apr 11, 2011

why I would be getting traffic on my outside interface that has a destination address which is not my assigned outside address? I recently set up my ASA 5505 on the network and gave it an available outside address of say 192.x.x.250 on interface vlan 100. When I assign vlan 100 to e0/0 and bring the port up, I start seeing lots of traffic pour into the ASDM Syslog with various destinations belonging to my subnet but that are not actually destined for my specific outside address of 192.x.x.250.They are showing a destination of say 192.x.x.85 or 192.x.x.29.

Cisco VPN :: Use Proxy Bypass On ASA 5510?

Oct 25, 2012

We have a custom web application which is heavily relying on javascript. We're trying to access it via the webportal but this application does not load correctly (it barely shows a white page).
 
the link is [URL] and SUBIF-ISP2 is the public interface facing the internet. This is the rule as displayed by the CLI:
 
proxy-bypass interface SUBIF-ISP2 path-mask oursubdirectory target [URL]
 
Despite having this command in place, nothing changes. I tried multiple combinations adding the xml and hostname rewrite or changing the interface but nothing, the page is the same like if this rule was not applied.

Belkin Routers :: N600 - Security System Is Not Working

Nov 1, 2012

A N600 Router Model F9J1102v1 router first installed in July 2012 with WPA-PSK, MAC Address Filtering and "Self Healing" enabled would not allow a new PC to connect via an RJ45 port. Belkin support ask for the unit to be reset to factory settings which is done and the Security system re-enabled again. Valid MAC Addresses start to be added and midway a PC is discovered in the Network without its MAC address added. Closer scrutiny reveals that another unknown device has also found a way into the router and that the 'Block' option on the MAC list is also failing to work. Anyone think of what one should do with this security shambles other than turn the thing off quick?
