Cisco Routers :: DDNS Service Configuration String RVS4000
Apr 15, 2012
How to to successfully configure and connect to a DynDNS account with RVS4000? This was working fine for me until recently when I think I upgraded the firmware to 1.3.3.5.I am trying to connecting to DynDNS.org service. In the past, I used the following string for the Hostname which worked: 'mysubdomain.domain.com&system=custom' (including small quotes). According to the RVS4000 documentation, all you should have to do is specify the host name with DynDNS but this clearly is not accurate.

I am trying to set up DDNS for my network. Right now there are only RV180W for DDNS providers (DynDNS, TZO, and 3322).I wanted to use a free DDNS provider, however DynDNS and TZO are now pay only (or only a short free trial via credit card). 3322 seems untrustworthy, as Google is reporting that it is a security risk?Anyway, my question is: "Is there a way I use another DDNS service other than the ones offered by default in my RV180W?"

I am trying to set up my rv042 to use the ddns service. The rv042 is directly connected to the ISP provided modem on WAN port 1. The problem is that instead of seeing the internet IP the rv042 is using the ISP sub net assigned IP.
LAN IP : 192.168.1.1 WAN1 IP : 192.168.12.9 WAN2 IP : 0.0.0.0 Mode : Gateway DNS (WAN1) :DNS (WAN2) : 192.168.12.1 DDNS(WAN1 | WAN2) : Off | Off DMZ Host : Disabled

I have found cisco's config for dynamic DNS on an ASA. However, I have seen many articles that the ASA doesnt support the HTTP update method that most dynamic dns services use.

I'm trying to setup a VPN tunnel between a Cisco RVS4000 on our side and a Cisco ASA5520, to connect a machine on our local network to a test server on the target side.
We have all the settings setup correctly and the tunnel is up and running, however, our local machine can't connect/ping to their server. I've tried a trace route both from the machine and from the RVS4000 itself, and they both get stuck after getting past 192.168.1.1. Is there any routing or NAT-ing that I need to do on our router? Or is there a problem somewhere else?

Purchased the RVS4000 in 11/2012 to work behind a NVG512 in (pass thru mode). I'm running firmware version V2.0.2.7. For whatever reason once or twice a month I lose access to the internet. Sometimes it's AT&T fault but other times my RVS4000 dosen't behave well. I finally took screen shots of every screen I configured in the RVS4000 to make it work in my environment. Last night we lost internet access again. Before unplugging everything I looked in the RVS4000 and found that my WAN setup had reverted back to a default Automatic Configuration - DHCP instead of the Static IP that I had previously saved.
It seems that my RVS4000 is losing just that WAN setting (port forwarding and Static IP Mapping data and VPN client data is still intact.

We have an RVS4000 router at two ends of a VPN tunnel. The VPN tunnel is working fine, however a phone at the remote site drops calls, even though they sound clear and unblemished. I have set highest priority on the port the phone is hooked up to at the remote site, and have set a priority for upload traffic on both routers, but the phone stills drops calls after 2 to 3 minutes.

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.

I am attempting to configure DDNS on an 1811W, but my configuration fails. Apparently,it is not connecting to the TZO server, because when I run <show ip ddns update> in telnet, the message "update destination not available, although rh.tzo.com can be pinged. I am attaching a copy of the config file. the ip name-server entries are my IP DNS, and the url/user name/ key entry was provided by TZO support.

I just purchased a RV016 router, upgrading from an older Linksys router only to find out that there was no support for TZO DDNS. I have used TZO for years now and don't really want to change to another service. Any way to request this from Cisco engineers for future firmware upgrades?

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.

my RV042 is not able to propperly update my ddns. If you try to resolve my dyndns subnet kitus-network.dyndns.org you will get 192.168.0.2. How can I make the router update my ddns with the real public ip rather than the private ip it "sees" on the WAN interface?

Region : UnitedStates
Model : TD-W8960N
Hardware Version : V3
Firmware Version : 1.4.0 Build 111130 Rel.54317n
ISP : century link
How do I test my routers ddns? My computer went down. So, my adsl ip address changed. I caused the modem/router to reboot. But the new ip wasn't sent to the Host (dyndns.org). I had to update my ip manually on [URL].

I have 2 internet connections in my office one via Verizon Fios and another one via the local cable company. On the fios connection I have an RV042 VPN router and on the Cable company connection I have an rvs4000 router, I would like to know if there is a way I can connect the 2 so I can share a printer I have on one of the 2 networks from the other network without using the VPN feature, like via an ethernet cable connected between the 2 and some kind of static route maybe?

I recently configured CISCO 3310 box with MSE version 7.2. Services are up and running in the box, I could add the MSE to WCS and also able to track the location using WCS. However, I could not connect the third party software to MSE web services to get the location information there. When I hit the server url "https://<my mse>" I get list of possible services like:
Error 404 - Not Found.No service matched or handled this request.
Known services are:
http://my server:8880/hs/
http://my server:8880/mdp/
http://my server:8880/admin/
[code]....
I browsed through the documentation (CAS_71.pdf) and found a text saying:
Note Port 80 will be enabled on the MSE if the enable HTTP command was entered on MSE. Ports 8880 and 8843 will be closed on the MSE when the CA-issued certificates are installed on the MSE. I am running the test system so I do not really want to install CA signed certificate, so I used self signed certificate and restarted the server, but it did not work.

When attempting to configure access controls from the advanced menu I enable the access control checkbox. I then follow the configuration wizard completing each step as directed by the wizard. When I complete the wizard and try to save the rule I get the following error message regardless of how I complete the wizard. "Name can not be empty string". Yes, cannot is misspelled in the message. I have tried every combination of choices in the wizard and many combinations of naming the rule to no avail.
This did work properly on a previous firmware version, probably 1.04 or 1.05. I have not tried back loading to the previous versions to see where it did or did not work. I don't know how well the router goes back and don't really care to reload all the settings again by hand if the automatic recovery doesn't work.I want to use this feature to control what hours certain machines on the network have access to the internet.

I'm looking fot a way to do static URL blocking with ASA and when the URL is blocked present a "Web Page" to the user saying that it's been blocked.
So, i was wondering if i can use the http parameter "spoof server string" to replace the original URL sent by the user for another URL that points to an internal web server holding a basic page saying "Your URL request has been blocked".
The point is to have a way to tell users that the page they are trying to browse is blocked by a policy.

Ive set up a rvs4000 with two vlans, one as a bussiness network and the other as a guest network. Everything works fine and the networks can not see each other. I would like to add wifi and I would like to do so with keeping both networks separate. I have a used 1130AG access point and was wondering if I could use this single AP for both networks. If so, how would I go about doing so? Is there a better suited AP for my needs?

I have an RVS4000 running V2.0.2.7 firmware that gives me an "Invalid Character(s) Found" error message when I try to edit an existing ACL.
I'm trying to deploy 57 of these routers and would like to be able to use a pre-built config dropped onto each router.
I initially planned on editing the exported config with a find&replace for my local LAN addresses. Since that didn't work the next reasonable solution would be to edit the ACL list (much more tedious, but still better than hand-entering every ACL on all 57 devices).
when this bug will be addressed? Alternatively, if there is an offline configuration editing tool I would be one happy camper to have it!

I have an RVS4000, not installed. How can I tell from the unit or the packaging that it is a v1 or a v2, without installing and switching it on (which I don't want to do now) ? Are v1 branded Linsys and v2 Cisco ? Can you tell from the date on the package (mine says copyright 2011) ?

I don't know if my vendor mislead me, but I need to do this: There is a public subnet in my office, not a 192.168.x.x, but a real Public IP.The reason is that we do VOIP and those are only servers. I installed a RVS 4000 in that location, and assigned a PUBLIC Ip to BOTH the WAN and LAN, since when I connect from outside, using either QickVPN or another identical router, I need to be assigned one of the PUBLIC Ip's on the remote LAN. That is the whole idea of the project, to locate servers remotely and make them use our set of PUBLIC IP's. Well, so far I cannot connect either with the Quick VPN client, or using the VPN Wizard. It goes and creates the tunnel, without error, but when I click test, it fails.

We have backup and other traffic over our vpn which is affecting our ip phone service between two sites. Our consultant suggested implementing QOS over the VPN to give the phone traffic priority. Is this possible with the rvs4000. Is there any good source saying how to do it. Is the setup of the QOS on this router similar to another router where this has been discussed.

I have problem with bandwidth management on my RVS4000.
That is the way how i done it:
All traffic (TCP & UDP on all ports)

Guaranted download speed 1kbps
Maximum download speed 5000kbps
after saving setting and rebooting router I have maximum download speed on my PC 12000kbps, Why QOS doesnt work ?

I am getting ready to setup an RVS4000 so we can use the VPN functionality of it, but I am not quite sure of the correct way to integrate it into our network though. I do not need site to site, just the client portion of it for a few salesmen/off site people to use. I have never used or setup a VPN before, so I'm learning everything as I go along.
We are in the middle of switching our ISP and I am waiting to set this up until the new service is live so I can test it prior to moving the rest of the company to the new ISP.
We are switching to Comcast, and will have 5 static IP's available to use. Currently, the firewall does all our NAT and is the forward facing device on our network. I would like to leave the firewall in place (although I am setting up a new firewall for the new internet connection) and have th RVS 4000 sit behind it and receive VPN traffic from a WAN to LAN rule We currently have a 192.168.100.0/24 network.
Do I need to setup another /24 network for the VPN to function behind (and still have access to the 100.X network), or is there a way to allow everyone who connects to receive a 100.X ip address from our DHCP server. I'm not sure how to set everything up with the WAN/LAN connections on the RVS4000 to acheive this.
We are running a domain on a 2008R2 server. The clients will be using laptops that are already part of the domain, if that will make a difference.

I'm having an issue with a Linksys RVS4000 which doesn't appear to be behaving as I think it should.I need to forward a port (Single Port Forwarding) through to an internal NAT host. However, I only want that host/port to be accessible from one host on the internet, for security reasons.
I have created the port forwarding entry and this works fine. I then created two rules in IP Based ACL - one to block all access to that port from the WAN interface and one to allow access from a single host.
However, it appears that when a port forwarding entry is added, it will completely bypass the ACL and allow all traffic for that port/host by default.Is this the correct behaviour?
Firmware version is v1.2.11

I'm currently dealing with a weird problem on a Cisco RVS4000. I'm trying to connect to a IPSEC VPN Gateway (NETASQ) located on the LAN side of the RVS4000. I'm using Green bow vpn client on the WAN side of the RVS4000. Basically I'm trying to get through the RVS.My VPN config is OK because i tested it on the LAN side of the RVS.
The RVS is configured like this: NO VPN configured.
Block WAN Request :OFF
FIREWALL,IPS,DDOS are OFF
NAT forwarding on for UDP 500 and 4500 directed from the wan to the ip of the VPN gateway. Seems right because iv managed to do this with other routers (different brands) on another site.I've wire sharked my vpn client and i keep getting ICMP destination unreachable (PORT UNREACHABLE) after my ISAKMP launching packet.Can the RVS nat these ports ?

I've been trying to disect this problem for a few months to no avail. The router allows me to connect to outside FTP only when IPS is enabled. The moment I disable the IPS functoin, the connection hangs and does not connect to a server. Reason I'd like to keep IPS disabled it is because it's eating up half of bandwith when enabled.RVS4000

I have a Cisco RVS4000 with Port 1 as a trunk connection to a Cisco SF300 switch. Port 1 on the router is configured 1untag,2tag,3tag,4ag. When connected directly to the router I can connect to the switches management IP. I would like to reach the switch remotely. I have set up DDNS and can access the router and I have have set a specific port to forward to port 80 on the switches management IP but this does not work. Should I not be able to Port Forward to the switch across VLAN 1?

I have an RVS4000 with FTP download issues. I have the latest v1.3.3.5 software and the latest ISP (1.5). Regardless of any settings changes, my FTP downloads always timeout. I have tried a new basic router and had no issues, so it is not the PC, FTP software, or the ISP. I have even put my PC into the DMZ and still no resolution.
