Cisco Firewall :: 3560X Gateway Address For All Of Current Devices
Jul 18, 2011
I have an AT&T Router that is my gateway to the internet, I have no access to it. I do have the inside ip address of it which is on my private LAN. Just for shiggles we will call it 10.25.240.1 255.255.248.0. That is my gateway address for all of my current devices.I have this shiny new ASA that I want to throw in there to eliminate a proventia and a sidewinder.
The diagram shows two stacks, these are my virtual server clusters with 3560X switches with the vlans configured, and several more switches all configured with vlan 832, connected to a 2950, which is connected to my internal 2600 router. I have 4 Vlans running on 4 different ip ranges, all controlled by the internal router, with only one vlan, let's say 832 that is trunked to the outside world. That vlan has 172.16.1.x 255.255.0.0 network attached to it. All is well, and traffic is routing behind the internal router, but I cannot seem to figure out how to get the traffic to pass thru the ASA. [code]

I have the dhcp server setup and working on our main 3560x.
The only problem is that it is not assigning the dhcp clients a default gateway.
I was not able to find it in the Cisco documentation and a google search is not useful either.

I have DSL, a firewall, patch panel and hubs.The network was already in place by three previous techs. I am not sure how the current setup is done there is no configuration map.The users in office 1 are all connected to a patch panel that then connects to hubs The second office users connect to a hub that then connects to the patch panel then connects to another hub.The internet is connected to a router that will be replaced with a firewall. Should it be setup like thisdsl modem > firewall > patch panel > hubs > Nodes

I have an existing ASA Firewall that is configured with an inside interface and an outside interface - communications is working fine in this configuration.I am trying to add a DMZ interface that will be connected to a 3560x switch - the new ASA and Switch configuration are below. [code] I cannot ping from a computer on the LAN (10.10.10.3) to the IP address of the DMZ Switch on VLAN 510 (10.50.10.1).I can, however, ping from the DMZ Switch (10.50.10.1) to the workstation on the LAN (10.10.10.3)

I have an ASA 5520 with a DMZ with private addresses that I SNAT to my outside network. From inside the DMZ I can reach servers by both the internal private IP and the public IP, except if the IP is from the server trying to connect. So, say I have server1 and server2. I can connect from server1 to server 2 with both public and private, but can't connect from server1 to server1' using the public IP. ASA logs show that packets are being denied due to land attack. DNS doctoring is not an option for me.

I just moved into a new place and the cable company supplied me with a Motorola sbg6580 gateway and I have a netgear wnr3500l router with dd-wrt. because of location I have computers plugged into both devices (htpc and game consoles in the gateway, desktops in the netgear). how would i configure the gateway and router so everything sits on a single network AND the netgear with dd-wrt handling all the heavy lifting (port forwarding mostly)

We are switching over to a new ISP and the settings from the old ISP Statstic IP,DNS, is on the Cisco 891 router. Question can I just edit the settings that are already on the Cisco 891 router. I clicked on the CCP exress Went to the Task Internet(Wan) Address type is set for Static IP which I can change and the subnet I can change. In the DHCP it is enable DHCP server on the Lan interface VLan1 and I want to keep the Starting IP address and Ending IP address. For the Section DOmain Name Server (DNS) Primary DNS and Secondary DNS I can change it. Where do I type in the Gateway address. I clicked on the Routing and I only see checked Enable dfault Route and checked INterface Fastethernet8. I don't anywhere that I need to type in the Gateway address anywhere in the CCP Express.

My ISP is changing out all the ADSL routers in our area and they have blocked the Default Gateway Address, so we can not access it via Web Browser. This is frustrating because they changed our Wi-Fi password, instead of just keeping what we had like an Einstein. They said they did it because of Hackers

I am on a University campus and they have provided the following to connect to the internet along with DNS server addresses:
IP Address: 192.168.25.24
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.254.1
When I connect my computer, it gives an error that the IP address and subnet mismatch, but it still connects to the internet just fine. However, if I try to put these settings into the DIR-655 along with my computer's MAC address, it gives me the error "WAN gateway IP address 192.168.25.24 must be within the WAN subnet" and requires I change it.

Client is having 1 file server running small business windows server 2003. Server is not configured with domain, it is working only on workgroup. We have around 15 users who are using that server as file server only. Now my main question is do i need to configure DNS server in that server?we also have internet connection running (have problem in that also, will explain next time) with wireless router to connected with switch. So do I need to setup dns in server also or just put static ip (I prefer static then dhcp) & dns server from ip will be ok? If I put dns which I got from ISP, so will it create any problem with using those file from server?the second question is..
What IP address, Default gateway and dns address I should use for Server & also client pc.
router ip - 192.168.1.1
server ip - 192.168.1.10
Currently no DNS setupcurrent configuration - Server
IP - 192.168.1.10
subnet- 255.255.255.0
gateway - 192.168.1.1
dns - 213.42.20.20 (from ISP)
dns2 - xxx.xx.xx.xx (from ISP)current configuration - Client
IP - 192168.1.111(to 115)
subnet - 255.255.255.0
gateway - 192.168.1.1
dns 1 - 192.168.1.10 (File Server)
dns 2 - 213.42.20.20 (from ISP)

We have a pair of Cisco 6513 switches, to which a selection of Wintel/Linux/UNIX servers are attached, but we have some connections that we can't identify and the data centre is a remote lights-out operation operated by a 3rd party in another country. determining which server NIC ports connect through (via patch panels) to which ports on the Cisco switches.In particular, I have a UNIX (HP-UX) server that has 4 dual port NICs (ie. 8 LAN ports), of which only one is assigned an IP address, but I can see that the other ports have connectivity at level 2 (HP-UX has a "linkloop" command that is analogous to an IP "ping" but takes a MAC address, and I get a response from each when I check from another server). This means that I know that there is a physical, electrical, and level 2 connection.The one server port with the active IP address set up shows in the switches address table ("sh mac-address-table") and it gives the port it is attached to. But the remaining 7 ports do not have IP addresses assigned and so are not listed in the table.

I have an AP541N-N-K9 Dual Band Access Point which I'm having some issues with. We have a few users with Android and iOS devices and they want to connect to our corporate network but when we configure the wireless network details in both OSs none of the devices get an IP address. We have an MS AD/DNS/DHCP infrastructure. On looking at the logs of the access point I can see the devices successfully authnticating but then I see the connection being disassociated and deauthed. A few seconds later the device attempts to get an IP address again and the same thing happens again. This loop just keeps on going forever. If we connect to the AP with an MS OS everything is fine.

we use LMS 4.2.1 and we noticed a strange behaviour when starting a discovery. From aprox. 160 devices some devices are displayed as IP Address instead of hostname. Every device is DNS resolvable and has a value for "hostname". I´ve tried every possible option in the global discovery settings but some devices have the IP instead of their hostname. how to fix this?

In mucking around with my 4500 I accidently deleted the ip address that I use to get into it with telnet and CNA. I have a console cable hooked up to and I'm in that way but the commands I got off the internet did not work. Those commands were set interface sc0 10.x.x.x/xx and set interface me1 10.x.x.x/xx. It didn't like interface and I notices when I did a set ?

I lost it on my old laptop. Figured it was time to get a new computer anyways, we bought a new one, along with a Playbook. Both the new computer and the Playbook have had this problem, though they were able to fix it.They all use Wi-Fi.

hrome threw me a DNS lookup failed. I go into my network settings and I noticed that I had limited connectivity. It would switch between no network access and no internet access every few seconds. After a bit of fiddling around, I got it to connect through assigning myself a static IP. This isn't exactly convenient because I use this computer on multiple networks. When I try to have it on automatic IP, I get no IP address or default gateway when I do an ipconfig /all. It would appear that my router quit assigning my laptop an IP for no reason whatsoever. DHCP is enabled on the router, and all other devices work fine. What could possibly be the problem here? I'm 99% sure it's not an IP conflict either. It's not being MAC filtered because I'm on the thing right now posting this through a static IP. It's not my A/V because it's worked great in the past. Perhaps I should also mention it occasionally says "unidentified network" instead of the SSID

I have added all of the devices to DCR and they show up with their hostname value in all of the device trees except for the fault manager views. In all of the fault manager views the hostname is not being used for the Devie Name field, rather the IP address is being used.

I would like to know what ip addresses I should see in this table. Shouldn't my default gateway IP have the same mac address as my computer or router? There are 2 different ip address/mac addresses from different a ISP than mine. I have a cisco DPC3825..I suspect a someone is spoofing my DNS.

We have a server connected to a 3560 switch which in turn connects to 6500s. The gateway interface is on the 6500. We will be changing the 6500s so the mac address for the gateway will change, however the IP address will remain the same. As we change out the 6500s the uplink connections to the 3560 will go down. This will flush the old mac address from the 3560.When the 3560 removes a MAC address does it update servers so they have to relearn the correct MAC address?

I've came across IP address that aren't enough for some users in the company. The IP addresses are more than enough to cater to the user's notebook or PC. However, some users does not know that there are actually limits to the IP we have, so quite a number of them actually uses their mobile / pads to tap the company's wireless.
I was wondering if i could restrict that particular user from tapping onto the network. I know it sounds a bit impossible because DHCP doesnt have that smart function to block whoever we sees deemed as a "nuisance".

My Speedtouch 516v6 modem does'nt provide gateway adress to the TP-Link router. The modem can work in bridged mode or routed mode and I want to use routed mode. TP-Link has PPPoE mode but I would like to use a dynamicIP mode in which the router obtain network parameters from the modem and it does, but it does not obtain a gateway address.

I have an Amilo Pa1510 (Windows XP) and I can connect to the router but not surfing (browser doesnt load any website). I have tried the commands "ping" to my IP address and it works but ping to the default gateway IP address doesnt work either.I am using the same wireless connection right now with my smartphone. I have downloaded an app that executes the ipconfig command in my Android. I have used the same gateway IP address in my laptop but it didnt work either. I have tried to set automatically the IP addresses in my laptop without success too. I have turned off and on both laptop and router and also checked in the system window that all the processes such as DHCP and DNS servers are automatic and enabled.
