Jun 12, 2012

My first time programming a Cisco ASA - Anyways I''m trying to setup up Ethernet 0/6 to be a DMZ Connection When I add port 0/6 to DMZ it gives me an error saying "The IP Address X.X.X.X /Subnet Mask cannot overlap the subnet of interface outside"So my question is I have an outside connection already configured - How can I make a DMZ connection with the same subnet mask with a different IP?

Setup A Wired Ethernet Connection To A Wireless Belkin Router?

Feb 24, 2011

I'm trying to set up a wired ethernet connection to a wireless Belkin router. The wireless router works fine - I have several devices that will connect wireless with no problem. The hp desktop I'm trying with the wired connection is showing that the ethernet connection is working, but it's not asking for the wireless network name or security code, and the internet will not work?I made sure the desktop was set up to automatically obtain IP addresses, then I did the "ipconfig /flushdns / ipconfig /release and ipconfig /renew commands, but it still won't work.

Linksys Wireless Router :: E2000 Setup Via Ethernet Connection For Mac?

Sep 18, 2012

I recently purchased a Mac and wanted to reset my wireless router and set it up using my mac. However, when I downoaded the software to set it up again, it said it was not compatable with my Mac OS (X Lion 10.7.4). I am sure there is a way to manually set it up via an ethernet connection, but I am at a loss as to how to do that. The wireless router is working just fine, I am able to connect to the internet wirelessly and there's nothing wrong with my internet service, however the wireless router is not secured.I have my Mac connected to the wireles router via an ethernet cord.

Cisco Switching/Routing :: / Routing Over A Point To Point Ethernet Connection?

Feb 15, 2012

I have 2 data centers miles apart. They are on a Paetec  MPLS. I have a Lightower point to point Ethernet link between the two data centers as well.  At data center A, I have a Paetec managed router ( The subnets behind that router are, and I also have a Cisco 1841 that is configured with fa0 addressed as and fa1 as Fa1 is the one end of the point to point Ethernet link to data center B.At data center B, I have a Paetec managed router ( The subnets behind that router are, and I also have a Cisco 1841 that is configured with fa0 addressed as and fa1 as I want to happen is any traffic headed from data center A destined for or to be routed through the point to point Ethernet link. I had Paetec add routes in their managed router to route any traffic headed for and to my Cisco 1841 ( wanted to do the same for traffic destined for and from data center B. Paetec added the appropriate routes to the router at data center B.Now, if I trace from data center A to, I see this:

1   <1 ms   <1 ms   <1 ms
2   <1 ms   <1 ms   <1 ms
3     4 ms     4 ms     4 ms
4     3 ms     3 ms     3 ms
So the routing seems to be ok. However after it hits, it gets lost after that.Am I missing something? Is this a misconfiguration on Paetec’s routers?

Cisco Switching/Routing :: 6500 Ethernet Sub-interfaces Over Metro Ethernet

Feb 20, 2012

I curently have 2 Data centers connected with a Metro Ethernet Connection.  Each Data Center has 6500 with Sup720s.  The Metro Ethernet connection is currently conected by a L3 routed interface. I now need to enable VRFs between the locations and want to determine the best way to adjust the Mero.  I was considering adjusting the routed interface to use Ethernet sub-interfaces.  Each VRF would be given a different subinterface over the Metro Ethernet connection.  I have done this on internal LAN connections but am concerned about exteding across data centers over Metro E.

Cisco Switching/Routing :: How To Use DNS On ASA5505

Sep 25, 2012

I have an internal server that is running DNS.  I have that server configured to foward out to OpenDNS.  I am using OpenDNS to do web filtering for my internal network.  It looks as if the relay is not working in the router and that it is not fowarding those dns requests from my internal DNS server and out to openDNS.  I have went back and added the name-server option for and (OpenDNS), but that has not fixed my problem. 

Here's my running config:

The error is Failed to locate egress interface for UDP from voice: to I can't understand why it even mentions IP 192.168. 1.200/ 137... I reset the unit configuring it from scratch and still no go. I have no given a static route to the out yet.. I need to get inter-vlan routing working first. [code]

Cisco Switching/Routing :: ASA5505 - Gateway Of Last Resort - Layer 3 Switch

May 23, 2012

I'm building the below network configuration:
WAN -------- ASA5505 ------<802.1q trunk>----- L3 switch -----<802.1q trunk>----- L2 switch w/ VLAN support
The following VLANs exist on the ASA and both switches: VLAN 10 (, VLAN 11 (, and VLAN 99 (
The ASA5505 performs the following functions: routing to/from the WAN, firewall, NAT, and DHCP for each VLAN.  It has an interface on each VLAN (10.10.x.2) for a DHCP server.
The L3 switch provides inter-VLAN routing and layer 2 switching.  The L2 switch provides layer 2 switching, with VLAN support.
What should the default gateway on the L3 switch be?  Should I set the IP of the physical interface connected the L3 switch to the ASA5505.

Cisco Switching/Routing :: ASA5505 / Network Design With Multiple Gateways?

Apr 11, 2013

remote location on MPLS circuit terminated on a Cisco router that has Internet connectivity through Central Site router.  We are installing a cable modem at the remote location that is to be used  as the Primary Internet Connection but still be able to use Internet through MPLS if the cable Internet goes down.  We want the failover/fallback to be handled automatically.
We have an ASA5505 for the cable Internet which then feeds into the ISPs modem. 
At first I was thinking about getting a module for the remote router so the cable Internet could be terminated on the remote router as well but that introduces a single point of failure.  I would also like to firewall both the MPLS and the cable Internet but if I do so on the ASA there is another single point of failure.

Cisco Switching/Routing :: Sub-50ms Protection Switching At Ethernet Layer (ERPS G.8032)

Jul 24, 2011

It is understood that sub-50 ms ERPS convergence can be achieved with certain HW/SW combinations.
1) What are the platforms supported (and with what FW/SW) has this been tested ?any results that can be shared?
2)  Link failure detection in GigE on Copper is slower compared to GigE  over "pure" Fibre; so no sub-50ms would be possible with Copper ring sub-50ms convergence achievable with "combo SFP ports" ?

Cisco VPN :: ASA5505-SW-UL Any Connect Setup And Able To VPN Into Office

I have a Any Connect setup and able to VPN into my office.i bought a ASA5505-SW-UL that is unlimited user (UL) software license but now the vendor tells me that: From the ASA you can saw the unlimited license is for inside hosts, instead VPN client's, by default, ASA 5505 included only 2 VPN client's and can supported up to 25 VPN client's, your license look only default 2 VPN client's. If need more VPN client's connect, you have to purchase the additional VPN client's license. I am just wondering his statement TRUE/FALSE, because i thought ASA5505-SW-UL means unlimited license

Cisco VPN :: Setup A Remote Access VPN On ASA5505 Firewall

Jun 2, 2013

I have setup a Remote access VPN on my ASA5505 firewall through the ASDM wizard.I can successfully connect with the Cisco VPN client. My firewall also shows me the VPN session and shows incoming Rx packets. However, Tx packets remain 0, so no traffic is going out. My ASA5505 is configured as router on a stick with 25 different VLAN's. I want to restrict traffic to one specific VLAN using a crypto map.When I issue a ping -t command on my connected Windows box, the firewall log shows me the following message:
"IKE Initiator unable to find policy: Intf outside, Src:, Dst:"
"This message indicates that the IPSec fast path processed a packet that triggered IKE, but IKE's policy lookup failed. This error could be timing related. The ACLs that triggered IKE might have been deleted before IKE processed the initiation request. This problem will most likely correct itself." [code] I have really no idea what's going on. I have setup a Remote access VPN countless times but this time it shows me the error as described above.

Cisco Switching/Routing :: 2960 / SG 300 Switch - VoIP Setup - Asymmetric Routing Not Working

May 21, 2013

I have a Cisco SG 300-20 as the core switch, layer 3. It is on VLAN1 and for VLAN2 (VOIP). All the ports are set in trunk mode. DHCP relay is setup on this switch.
The phones connected into a layer 2, Catalyst 2960-S switch. All ports are set in trunk mode. Default gateway on it is set to
DHCP for both VLANs is provided by a Windows Server 2008 R2 server (the relay IP
There is also an ASA 5510 in the mix which is It has a route added to it for the network to go to the SG 300 (
Just the two switches can ping each other on the 192.168.5.x network when I "add vlan 2" to the trunk port that is connected between the SG 300 and the 2960. The phones don't get DHCP on the 2960 switch. And I cannot ping 192.168.5.x from the ASA or anything else on the 192.168.4.x network.
After a bit of reading on intra-vlan routing for the SG 300 switch, I am thinking the SG 300 has to be the "center" of things so I need to make it to be the gateway for both VLANs and change the ASA to for VLAN1, etc. And I really can't do asymmetric routing with this switch.

Cisco Switching/Routing :: 3560G - How To Setup Per Vlan Routing

May 14, 2013

I'm trying to set up per vlan routing on a 3560G switch but it's not performing as I would expect. I've got a server on the 109 vlan with a address and a default gateway of this address is an HSRP gateway and currently resides on When I traceroute through to my user PC on the internal network it receives a response from However, it is then denied by an ACL on the internal firewall which has been applied to interface Eth0/0. It should arrive at the firewall on Eth0/2.109 as it has the address.
My goal here is to route traffic on the 101 vlan to a seperate interface on the internal firewall from 109 vlan traffic. I'm either doing something wrong or these routing commands aren't designed to work in the way I'm expecting (I couldn't find any documentation on the ip route command where it is followed by different gateways for different vlans)
interface GigabitEthernet0/12
description Internal-FW Eth0/2
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 109
switchport mode trunk(Code )

Cisco Switching/Routing :: 892W / LAN Versus WAN Ethernet

Feb 14, 2012

I own a Cisco 892W router. The router has 2 WAN ports and 8 switch ports. Now I know -
-WAN ports can create sub interfaces, assigne IPs, cannot be assigned to a VLAN - sounds very much like a routing port. (sh interface gives - Hardware is PQII_PRO_UEC)
-Switch ports are for VLAN assignment, trunking, IP assigment etc,. (sh interface gives Hardware is Fast Ethernet)
I know they are different but at the same time confuced what the difference are? I also know on some 3xxx series switchs you could say "no switchport" and translate a switch port to a layer 3 port. But on 892W you can't do this? Struggeling to understand the difference.
