Cisco :: Which DDNS Provider Works When Auto-updating IP Address Via 1801
May 28, 2013
I have been struggling to find a DDNS provider from which the IP address can be updated from a Cisco device.One does not seem to support it, (Free-DDNS) other must be paid for (No-IP.org) while the free version does not update the IP address in my case, etc, etc.The device that is directly behind my modem is a Cisco 1801 router.My question is, which DDNS provider works for you when auto-updating the IP address via the Cisco router?

I have two of the Wrvs 4400n V2 VPN (V2.0.2.1-ETSI) routers in different countries, one in the UK and one in Australia. They are permanently linked using the IPSec VPN tunnel and the dynamic DNS feature (DynDNS.org). I have found that the router in the UK does not update its IP address automatically to the dns website when the UK Internet service provider changes the WAN IP of this router. This makes the IPSEC tunnel go down until I telephone the UK location and ask to force the router to update its IP address with dyndns by restarting it or by using the routers configuration to re-save the password for dynamic dns.

I'm trying to use Cisco IP SLA to bench mark voice traffic peformance before and after I apply QoS to the network.
* I've setup IP SLA in both directions over a DSL connection between a 7600, and an 1801
* I've setup IP SLA in both directions over an Ethernet WAN link between a 7200 and another 7200
ip sla 1
udp-jitter 10.101.1.1 32770 source-ip 10.101.2.1 source-port 32770 codec g711alaw

ip sla schedule 1 life forever start-time now

I have a problem in that I'm not getting any meaningful data from the IP SLA statistics for Voice Score Values:, or any data for Latency one-way time: for any of my tests(x 4).
After a day of testing it seems the MOS score never changes from 4.34, and the ICPIF never changes from 1 ?Is there something wrong with my config? Is this working properly or could this be a bug?

I have a port on 7600 connecting via Single Mode Fibre to my service provider. Service provider has 1000-Full with auto-negotiate. I am seeing following output on my 7600. [code] if this interface is only capable of doing 1000Mb, how come it is showing 100-Full. If I change to nonegotiate option (both my side and provider side), link goes down. My provider has confirmed they have 1000Full their side.

I have Latitude E6410 and connect to internet through wireless network to Zyxel ADSL modem. My problem has started 20 days ago when I was connected then I was disconnected from internet. The status is as below:
- I can ping the modem which means the laptop the link between modem and laptop is working while I can not ping any address or website even the provider's DNS. At the same time, if I connect the LAN cable, every thing is working properly. I tried with different laptops and there was no problem. To resolve the problem temporarily, I have to restart the modem or change the IP for my wireless card. In this case it works for another 30-60 minutes. the issue is the same when I use different modem.

Last two weeks, I have had a problem connecting to public hotspots. My own WiFi network is fine, but while I am connected to any public hotspot I get the 'no internet access' message on the wifi symbol.While connected to my own network, ipconfig/all shows that I have an Autoconfiguration IPv4 address in the (correct) 192 range - but when connected to a hotspot, the address is in the 169 range, or occasionally (as in the instance below) in the 10 range. Clearly this is the problem, but I cannot figure out what has caused it. Is it hardware? Software? Malware? Or user error?I have run the Wireless Test and the log results are pasted below.

The public IP address of my 2800 router where all VPN clients terminate will change shortly. There are some technique to auto-change the client´s profile for clients to connect to the new IP address? I have seen that VPN 3000 concentrator is able to do this so i can´t get one of those right now

How Stuff Works "How Network Address Translation Works"."This is where NAT (RFC 1631) comes to the rescue. Network Address Translation allows a single device, such as a router, to act as an agent between the Internet (or "public network") and a local (or "private") network. This means that only a single, unique IP address is required to represent an entire group of computers." so let's say 6-7 pc's can have access to the internet using the same IP. doesn't this causes any problems? what if one of those pc's was used fore doing something illegal? how can they spot it later on? or what if 2 or more pc's access (from that subnetwork) access the same website with the same IP?

I'm working on a friends laptop that used to connect wirelessly to their network no problem, and all of a sudden it would no longer connect at all. It a 5 year old Gateway laptop running Windows XP Media Center. It just hangs at "Acquiring network access" and never connects. I'm pretty sure it's their network because it works on my home network perfectly, connects and stays connected.
Can you give me some pointers to do to the laptop and/or the network? I normally would start fresh with the wireless network, but they have a bundle package of AT&T (internet, phone & TV all-in-one) so the router is branded AT&T and don't want to mess any of that up.

Writing my first router config from scratch for an 1801. I have wireless devices able to connect & authenticate with WPA. Wired devices can talk with wireless devices & on both interfaces devices obtain a DHCP lease. I can ping web based resources from the FA0 interface; the problem is, LAN devices can't ping has FA0. I'm pretty sure (well a hunch) that this is going to be down to NAT

i have a cisco 892 router that is behind a NAT/ROUTER/DHCP device of the ISP.i need to configure DDNS but i get a privat ip on the Cisco "WAN" interface. i need a local ip/port to be available from the outside.i have configured de ddns service methode (Dyndns) [code] This wil send the private ip of de "wan" interface and that wil not work. <A> in de connection string wil be my private wan ip i get from the dhcp of the ISP .... ik can add a static rout on the ISP, but can not disable the router function (like bridging....) is it possible (with script or someting, MY IP LOOKUP) that the cisco router know's his real public ip, and that this ip is used to update Ddns ?

I have a Cisco 1801 that I am trying to set up for my DSL connection. I have configured the router but when I try to access a web site I receive the Http 404 page cannot be displayed error. I have checked my DNS server on the router & I believe that I have configured it correctly? I am hoping that one of you more experienced individual can take a look & tell me where I might have gone wrong. I have included the current running-configuration for your viewing pleasure.

I'm trying to set up an 1801 router with two WAN interfaces, fastethernet0 and fastethernet1. On the LAN side, I have two subnets. One subnet's internet traffic should be routed over fastethernet0, the other over fastethernet1.I've setup some route maps to accomplish this. I can surf the internet using subnet 192.168.2.0/24 fine, all traffic goes out of fastethernet0. However, and this is where the problem is, if I try to reach the internet using subnet 192.168.3.0/24, all packets go out interface fastethernet0 with the source address of fastethernet1!When I'm surfing the internet, from subnet 192.168.3.0/24, packets should be going out fastethernet1, now they're going out fastethernet0.

I have two offices - see attached diagram. They use 192.168.0.0/16 for private IP addreses.They're connected via site-to-site VPN. Mostly works well, except some traffic doesn't return and I think it's due to NAT?When a workstation in remote office tries to access web servers in the local office which using private IP addresses (e.g. .64.40), traffic never returns. The web servers in question are also accessible publically - the Cisco 1801 in local office has a static route:
Local1801# ip nat inside source static tcp 192.168.64.40 80 111.111.111.2 80 extendable
The problem seems to be with the local 1801 router. tcpdump confirms that return traffic exits out of ods1's external interface and tcpdump confirms that traffic does not come into remote workstation's interface (neither with .64.40 as source IP nor 111.111.111.2 as source IP)
Remote887# show ip nat translations - none.
Local1801# show ip nat translations
Pro Inside global Inside local Outside local Outside global
tcp 111.111.111.2:80 192.168.64.40:80 192.168.10.254:54990 192.168.10.254:54990
What I don't understand is why a nat translation entry is created. My understanding is that it should only happen when ip packets are sent to 111.111.111.2:80 I don't see that any packets would be sent to this IP address when accessing the site across the VPN - in fact the VPN peer address used is not this one.I cannot figure out why on earth this website cannot be accessed via private IP. I have tried clear ip nat translation * on both routers with no luck.

I have a number of Cisco 1801 routers connected to BT UK’s ADSL2+ Annex-A Wholesale Broadband Connect [WBC] services. The routers are experiencing connectivity issues. There is a cisco product bulletin that defines v4.0.0.18 as the version of ADSL Firmware required on the Cisco 1801 when connecting to this BT service.I would like to upgrade the ADSL Firmware for these routers but I cannot find v4.0.0.18 for the Cisco 1801 on CCO. All the 4.0.0.18 downloads appear to be for various flavours of 800. The Cisco product bulletin shows the 1801 as having the same chipset as the 857,867,877 and 887. Can I use the Firmware from one these 800 models? The MD5 Hash for the code suggests all of the these 800 model use the same code?

I have a Cisco 1801 Router, but whenever there is anything plugged into the integrated 8 port switch for example two computers, I cannot get them to ping each other. All of the ports are on the same vLAN.
I am a Cisco newbie, so sorry if this question/query is really basic. Is there anyway I can test the integrated switch to see if it is faulty.

My client has about 15 public IP addresses for their WAN network. All the internal network IP will be dynamic NAT to these 15 IP addresses to communicate to Internet. Since they are dynamically NAT, if anybody want to access my client internal network from outside internet, we usually advise them to use the whole range of IP.
The modem router used to dynamically NAT these 15 IPs are Cisco 2800.
I am thinking of the configuration using WAN DDNS on this Cisco 2800 for combine these 15 IPs to a DNS name by DDNS method (or any other way beside the DDNS) so that outside people can use one DNS name instead of whole range of IP. In case there is limitation of configuration of some outside people can use only one setting instead of one whole range of IP, they still can access by using one DNS name.
How to implement this on Cisco 2800?

I am trying to configure TZO DDNS on my 1941. The DDNS lines in the configuration file were provided one year ago by TZO support for a 1811W router, which was working befor i migrated to the 1941. I have attached a config file and a debug file. The unusual part of the debug file is session id 0x95. I thnk this is the format the router would use if it had been configured using CCP. I had tried CCP initially but it didnt work, so I deleted it from the configuration and used CLI instead. Session ID 0x96 is the call the router is making using the CLI configuration, as seen in the attached config file.
I am not sure where the problem is here. it appears to be logging on to TZO. It also appears that the router name is being added to the logon ID in session 0x95...ie instead of myname.net the router is sending cisco1941.myname.net ---not sure if this is relevant or not. It also appears that the update happens? At least that'w what I can garner from the log file.

Network Setup
===========
2 Site to Site VPN tunnels has been established, it is a hub and spoke topology. The hub is ASA5520 and the 2 spoke are a 1841 and 1801 router. The tunnel is able to pass traffic, it's a full tunnel VPN.The tunnel randomly disconnect for no reason. When I check the logs I can see some errors :
%CRYPTO-4-RECVD_PKT_INV_SPI: decaps: rec'd IPSEC packet has invalid spi for destaddr=x.x.x.x, prot=50, spi=0x5F822579(1602364793), srcaddr=y.y.y.y
%CRYPTO-4-IKMP_NO_SA: IKE message from y.y.y.y has no SA and is not an initialization offer
The actual address have been replace by x.x.x.x and y.y.y.y. I frequently have to peform clear crypto isakmp on the spoke routers to revive the VPN tunnels. Is there a way the tunnel can be re-establish again without manual intervention?This keep happening on a random basis and I have living with it for years. I have looked at cisco website troubleshooting tips and but no luck in finding out how to resolve it.
Below is my config on one of the spoke router:
