Cisco Security :: 2800 - Internal Wireless OWA Isn't Working
Nov 18, 2011
I'm running an exchange server beings my 2800 router and its all working well i have setup NAT and OWA is working well when external and on the internet but when the phones are on the internal wireless OWA isn't working and if u telnet the external ip on that forwarded port it doesn't forward i believe this is the fact the port forward rule "ip nat inside source static tcp 10.0.100.7 443 interface Dialer0 443" is for the dialer interface only and as I'm internal nothing but I'm show to forward any request on that port.. ill include the config below
!!no logging buffered!aaa new-model!!aaa authentication ppp default local!!!!!aaa session-id common!clock timezone WST 8 0clock calendar-valid!dot11 syslogip source-route!!ip cef!ip dhcp excluded-address 10.0.200.1 [code]......

I have a 2800 with one Gigabit interface connection to our Lan and the other interface connected to the internet with a public IP address. Now I'd like to setup the router to resolve both internal and external DNS requests. Thus requests like www.google.co.za and LocalLanPcName should be resolved to their public and private IP's respectively. [code] When I ping any name the only DNS server that is ever queried is 192.168.1.200 (it does resolve internal name correctly though).
None of the other servers are attempted to resolve the name. It does not matter if I specify a FQDN or not.
How do I setup the router so that my internal resolution is handled by 192.168.1.200 and .201, while external resolution is handled by 41.160.36 and .37. Or alternatively, how do I configure it to at least try all 4 specified name-servers for resolution, and not fail after trying the first one unsuccessfully.

setup a DHCP server on a WLC 2504. I'll try to resume my configuration:
I have 2 networks: inside users (vlan 1) and external users (vlan)
My controller uses the port 1 to connect to the switch, which has a trunk with WLC.
I have two routers, one using vlan 1 (192.168.3.0/24) and one using vlan 10 (200.X.X.X). All ports to these routers are access ports on their respective vlans.
I have 2 SSID, one for inside, other to outside. Inside is working very well.
To the outside I created a DHCP escope and already set the IP of the management interface 192.168.3.119.
Managemente interface (vlan 1 inside): 192.168.3.119/24
Outside interface (vlan 10): 200.X.X.195 - Default gateway 200.X.X.X.193
I alredy checked the DHCP Proxy in Advanced option.
See the output of the debug client:

I have been trying to create a Guest WLan on my 4402 WLC system and have found several confilcting documents explaining the procedure. During this process I have notices that although the current corp wireless works, there was never a virtual interface created for it. Instead it uses the same Wlan/Vlan as the ap manager and managemnt interfaces. Could this by why I cant seem to get the Guest access working? or is this not a problem after all since the wireless does work.

We have 3 internet links from different providers connected to configured WAN 1,2,3 in RV016. A remote client needs to connect to a internal VPN Server behind RV016, so we use one-to-one NAT to publish the internal server ip to a Valid IP from WAN3 and setup protocol binding in Multi wan to all trafic (TCP and UDP) from the internal VPN address exits with WAN3.
So, the remote client tries to connect to VPN using this ip Address from WAN3 and sometimes work and sometimes not. It's clear to us that the problem lies in the response from RV016 not coming always from WAN3, because if we disconnect the two other links (WAN1 and 2) Its works flawless.

Just got a new router. All of my devices connect fine to it except for the desktop that is using an external Linksys wireless adapter (WUSB54AG).The desktop is running Windows XP (Home Edition) SP3.The latest driver for the adapter has been installed (3.0.18.0).I am able to connect if security on the router is turned OFF.The router has 3 security options:
1) WPA-PSK (TKIP)
2) WPA2-PSK (AES)
3) WPA-PSk (TKIP) + WPA2-PSK (AES)
My understanding (from Linksys tech support) is that the device SHOULD be able to connect using WPA-PSK (TKIP). My Linksys Monitor indicates that the device is connected to the access point but not the internet (when I used WPA-PSK (TKIP). The IP address that is assigned is 169.254.3.129 and not the expected 192.168.1.x.When I turn security OFF on the router, the device can connect and I am assigned a "good" IP address (192.168.1.x).

I have a WRT610N (v2) router and I recently updated the firmware to the most current version 2.00.01 build 15. I can no longer set WPA2 security for both bands (used to work just fine). Every time I try to save settings for WPA2 for the 5 GHz band, it tells me it was successful but then displays that the security mode is disabled (and it shows up on my computers list as not having any security enabled. If not, where can I get a copy of the old firmware that worked?

I am setting up ssh on my 871 router and I get prompted for only a password. I have typed in the correct password and it doesnt let me in. I also have telnet enabled and with telnet I do get prompted for both username and password and I am able to login. I would like to setup ssh so that it used the local username and password. This is what my vty has.
line vty 0 4
access-class 23 in
privilege level 15

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.

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?

I am having issues figuring out how i can make AppleTV,Airprint, Airplay, etc show up on Ipads that are connected to the wireless network. The controller is at a main site which is seperated by 2800 series routers at the remote sites over 100Mbs links. Ipads connect and tunnell back to the main site. I've tried enabling FlexConnect but the devices still get the main site's addressing so i'm guessing they are still tunneling unless the AP loses connectivity to the controller. I have two SSIDs (staff and students). I have tested with just setting the staff to FlexConnect. Do I need to set both SSIDs to FlexConnect to make them dump data locally? AppleTVs are connected wired to the local networks and get addressing associated with that building.

I have a Linksys WRT610N wireless system with WPA-PSK security and this works fine with several computers but now one computer detects the wireless security as WEP and can thus not connect to the router. I have tried to manually connect to the router with correct security WPA-Personal (TKIP) and correct password but then the computer says "settings saved on this computer for the network do not match the requirements of the network".How can I get the computer to detect the correct security? The computer is running Windows 7 home premium.

The two controllers are having two internal DHCP servers with the same range in LAN (enx1,enx2). but i have specified which is primary DHCP server(enx3) in WLAN interface.
Now if a new user added into network, will he get IP address from primary dhcp(WLC) or AP connected WLC.
if two users connected to 2 diff AP's which are connected to 2 WLC will get the same IP address? since having same address pool configured.

I have an 891W with the internal AP. I want to update the AP's software but can't find anywhere to get it on Cisco's site. If I go to Download All, Routers, 800 series, 891W all I can choose is IOS, IOS ROMMON and upgrade to LWAPP. If I go to Wireless Wireless integrated service routers, 800 series, 891W I get IOS and IOS ROMMON.

I am wondering if the folowing is a valid configuration:
WLC2504
AP2600
I need 3 SSID/VLAN, 1 for corporate devices, 1 for coporate smartphones, 1 for guest.
Port 1 on the 2504 should be used for management and corporate devices and connect to the corp network. Port 2 is for smartphones/guest and will be connected to a Cisco ASA 5515 that is connected to a second ISP.
Corp devices should get IP from an Windows DHCP. Smartphones/guest should get IP from the WLC. Is this possilbe? I read this in a document "To use the WLC as a dhcp, you need to enable DHCP proxy as it is required." Some how I am imagining that this will mess with the Windows DHCP. Is it better to use the ASA as DHCP for smartphones/guest?
