Cisco WAN :: Configuring Linksys Router To 851W Router?
Oct 25, 2012
I have a CISCO 851W router in the garage that I want to connect to my Linksys router in the office, which is connected to the internet.The 851W is connected from it's WAN port to Lan port 1 of the Linksys router. Now, currently that ethernet cable is a straight-through cable. Does it have to be crossover? If so, I can fix that.
I want the default gateway for the CISCO router to be 192.168.2.1. I am not sure how to configure that. [URL]

I am very new to using the CISCO IOS. Here is the situation: I have a CISCO 851W router in the garage that I want to connect to my Linksys router in the office, which is connected to the internet. The 851W is connected from it's WAN port to Lan port 1 of the Linksys router. Now, currently that ethernet cable is a straight-through cable. Does it have to be crossover? If so, I can fix that.So I have no idea how to give the 851W internet access I am a total CISCO noob. I will leave it to you guys to recommend what IP to assign the router and subnet.

I need to front-end my ISP's router with another, giving me a DMZ. I have bought an EA2700 for this but I can't find how to configure it.
I plan to have the DMZ network as 10.1.2.0/24, with the ISP's router at 10.1.2.254 and the EA2700's "upstream" connection as 10.1.2.1. The internal network (where most of the clients reside) will then be 10.1.1.0/24, with the EA2700 itself at 10.1.1.254 and a DHCP range 10.1.1.100 upwards.
On the basic setup screen I've set the Internet connection type to fixed IP, 10.1.2.1; I've set its default gateway and DNS1 as the ISP's router at 10.1.2.254. Then further down in network setup I've entered the *internal* address 10.1.1.254 and set the DHCP range and netmask appropriately. I'm getting the error message "The IPv4 address and gateway are not in the same subnet mask". But the only gateway I've entered is the one by which the *EA2700* knows how to route upstream traffic, viz the ISP's router at 10.1.2.254. Or am I misunderstanding?
More fundamentally, can the EA2700 be configured in this way?

We have network that uses a Cisco router and use a WAP54G to access the network wirelessly.
We use static IP address so if someone wants to use the wireless an IP address has to be assigned to it and be manually configured for IP Address, Gateway, Sub Net Mask and DNS.
This is becoming unwieldly, but it is safe. Is there any way to config the WAP54G as a router that would automatically assign an IP address in a range just for wireless devices.
Therefore the wireless devices could be set up as DHCP and we would use WPA/WPA2 encryption with a passkey, instead of just assigning static IP addresses.

I recently bought an EA2700 in hopes that it will make my connection faster, stronger signal and stable. However, this is not the case. The connections keeps dropping and the range is the same as my Verizon-FiOS router. Anyway, I'm hoping that a fix be distributed to address this issue. I can't return my router to the vendor anymore.
Now, since I have two routers, I want to be able to leverage EA2700's dual-band feature and the Guest-access feature but I can't make this as a main router since my FiOS router should still be able to supply IP addresses to my cable boxes, thus, I can't configure it as a Bridge. I'm thinking if I just split the IP distribution as follows:
FiOS router: 192.168.1.2-110
EA2700: 192.168.1.111-150

I have a Linksys WRT54g router that works fine, but the signal is not very good on some points of the house.So I bought a TP-Link 740n to use as a second router. My idea is to connect both routers with a 10 meters lan cable that I have, to make the signal better on points that are distant from the main router (Linksys) or separated by walls. When job is done, will I see two different networks (one for each router) on my laptop or only the "original" signal (WRT54g)?

I am following instructions I found to set up my wirelss network, but am having trouble configuring my router. I'm specifically at a standstill, because I can't connect to http://192.168.1.1. I pinged the router and got a response and went to run/ip config to confirm I have the right URL for the router, but still not able to get to the URL.

I'm considering purchasing the "Cisco Linksys - E1200 Wireless-N Router with 4-Port Ethernet Switch". Before I do, however, I want to know how to configure it as a wireless bridge to my existing wireless network.I have a hardware device with only an ethernet connection (no wireless option avaialble). I want to connect the device to a wireless router / access point, in this case it would be the e1200, and then connect to my existing wireless network. The e1200 would be acting like a client of the existing network.I found this article but Step 8 is causing concern. I do not want a wired connection. The two routers must connect wirelessly.

I have looked up the command sequence for port mirroring and it seems pretty straight forward however in my case the command will not execute.
I have a 851W with 12.4T
If I do: #monitor session 1 source interface fa 4 (wan port)
i get the response invalid input detected however if I do the same command for fa 1, fa ,2 and fa 3 they work
Using the ? shows the valid entries are [0-4] for fastethernet
I just want to monitor WAN traffic with WireShark, particularly DDNS requests, with a spare PC connected to a free lan port.
I would use a hub on the Wan connection but unfortunately I do not have one at the moment.

I have looked at the Cisco Feature Navigator and according to the output with IOS 12.4(15)T1 thru T13 there is support for multiple SSID's and the feature "Multiple Basic Service Set ID" should be supported.
When I try to invoke that command mbssid on my Dot11 interface I get 'Invalid' response. Am I missing something here? Is the Feature Navigator misleading me or am I doing something wrong?
All I want to do is broadcast both SSID's that I currently have configured. Currently only one guest mode SSID is allowed and broadcast.

I bought a Cisco 851W router from a coworker about a year ago and tried setting it up at my home with nothing but headaches. I finally gave up and went with DD-WRT and have yet to look back (my $40 router outperforms this thing on so many levels, but I'm getting off-topic!). I recently re-discovered this beast and pulled it out of storage to see if I could get a test network setup at home to practice on. I checked for any IOS updates and downloaded (and installed) the lastest image (c850-advsecurityk9-mz.124-15.T15.bin). I consoled in and verified the initial 10.10.10.1 IP was configured in the VLAN1 interface and directly connected a PC to one of the switchports and pulled a 10.10.10.2 address. I pull up SDM from my browser (I have used FF, IE, and Chrome, all with the same results. Java version is the latest, 6 Update 26.) and it launches the initial configuration wizard. I go through the steps and get up to the DHCP Configuration (after LAN, before Internet/WAN setup) and try to click Next and nothing happens. It doesn't freeze as I can easily go Back, but can never move forward beyond the DHCP configuration. Pressing Cancel on the wizard just shuts down SDM as a whole and exits.
In my troubleshooting steps, I did notice that as soon as I click Next in the DHCP configuration, nothing will happen in the wizard, but the SDM window in the background will automatically present the "Apply Changes" and "Discard Changes" buttons, which weren't there in the previous steps. Of course, neither of those are clickable due to the wizard being open. I really don't want to configure this thing from scratch using the CLI if I don't have to..is there ANY way I can bypass the SDM Wizard at all? Also, I'm running SDM Express, would downloading ASDM and trying to connect from there make any difference?

I have been trying to get my 851W to work with DDNS for a long while now. In fact I walked away from the problem in frustration and loaded DD Client on a Linux box until I had time to re-visit this. The folks at Zone Edit were not able to offer much with CLI problems.
When I debug DDHS updates I get to a point where the the router tries to resolve the DDNS update address and fails.So I have a number of questions:
a) Is this error the result of lack of DNS server names written to the config?
b) My WAN interface is a DHCP client to my modem. If the DDNS updater does need to resolve a name, shouldn't the DNS server info be provided by the DHCP process for the WAN interface? How do I ensure that name servers are automatically assigned for the DDNS updater to use?

We have 7200 router on which two links from different ISPs are terminated. Right now one link is primary and the second one is redundant.Now we have procured our own IPs and plan to run BGP with both the service provider. Can we configure GLBP on the router so that both the links can be simultaneously used and when one goes down the other takes the full load.

I use the cisco 871 router as a firewall to my home-office. I have configured two vlans for each seperate port. That is, FE0 configured as VLAN 10 ----> connected to Layer 2 Switch, FE1 configured as VLAN 20 ----> connected to another Cisco Layer 2 Switch,FE2 not in use, FE3 not in use and FE4 is connected to WAN.I got 100Mbps speed from the ISP, but I can see that I only get 50mbps even connected to VLAN 10 or VLAN 20.Does configuring two VLANs on Cisco 871 router divides the bandwidth (to Internet) into half?

configuring my Cisco 2951 router. There are three routed interfaces that I need to configure: one for the internal LAN, the second for another private subnet that connects to a Data Centre and the third for the WAN connection. I have configured the Ge0/0 interface as the LAN interface with the internal network 10.17.0.0/24. I have also configured my WAN interface Ge0/1 for internet connectivity. Now, I need to configure the third interface Ge0/2 that will connect to the Data Centre. This will be a private point to point switched ethernet link. The Data Centre will host a secondary domain controlller. So, I want it to be on the same network as the internal LAN, i.e., 10.17.0.0/24. I want to be able to see all other devices that will be located at the Data Centre just like I would see all devices connected to the internal LAN.The problem I am facing is that Cisco 2951 does not allow me to configure two routed interfaces to be on the same subnet. Is there any way to work around this problem and configure both the internal LAN and the Data Centre private network to be on the same subnet.

I've created two configurations. One for the router side and one for the AP point side. However, I am having trouble getting the internal AP to bridge to the router properly. It is my understanding that the Wlan-GigabitEthernet is the internal interface connecting to the AP and the BVI1 together. I can't ping any ip address on the router side from the ap and the radio is active and we can see it but it seems that it doesn't give an ip address. [code] Is it a VLan issue or an ip issue but I could use a second opinion. I've included both configurations.

We are having problems configuring NAT on our Cisco 1921 Router. Below is the running config. The problem we're having is for example our FTP server 192.168.1.16, cannot be accessed from its outside IP address, which is NATed on the router. The server is verified to be up and running and when we do a show debug ip nat, we see the router is translating outside users attempting to access the ftp server to it's correct internal IP address.
