Cisco Routers :: RVS4000 - Preventing Access To Backend / GUI
Aug 16, 2011
I've got an RVS4000 router with the latest firmware - V2.0.0.3, and just setup Dynamic DNS on it. However as I access the url of the Dynamic DNS, I get pointed to the routers web backend/GUI, which is natural as it's situated on port 80 of the router.
To prevent the whole interwebs from accessing my router's settings, I've quickly forwarded port 80 to a non-existent IP on my LAN. However this solution feels a bit fragile, so how can I ensure that only computers from inside my LAN can access the routers GUI?

I have a RVS4000 and I would like to setup a Ping monitoring from the outside to a device behind RVS on lan network. I have created a rule to allow a service PING for range from WAN 46.xxx.xxx.xxx - 46.xxx.xxx.xxx to host 192.xxx.xxx.xxx but unfortunately this is not working. I can confirm that I can ping host 192.xxx.xxx.xxx from diagnostics on RVS.

I am trying to setup the VPN access using QVPN with RVS4000 but ran into difficulties I was able to connect to the router using QVPN from WAN, and able to access the router's admin page (my router's ip is 192.168.0.1). However, I am unable to access anything else on the LAN, including servers and printers. To make it clear, I am able to access all servers and printers when I am on the LAN! But nothing when accessing from the WAN via QVPN.

Would there be some reason why I cannot change the Access Restriction to Allow? I also can't add anything into the Website Blocking by URL Address or the Website Blocking by Keyword. I can't type anything in the fields. I've tried rebooting, other browsers and even other computers but nothing seems to work.

I recently bought an RVS4000, and unfortunately forget the "if it ain't broke, don't fix it" rule, and flashed it to the latest firmware (2.0.2.7). Subsequent to doing that, it has been inconveniently dropping the connection to my ISP and completely locking itself up to a point where a manual reboot is required, usually about 4 hours after any outgoing activity (which usually means 11pm!).
Goggling my way round seems to suggest that this could be a firmware problem. The accepted wisdom is that I need to use the RVS4000 Upgrade Utility to get back to a lower version, so I have downloaded and installed V1.3 from the RVS4000 support area. However, though I think I followed the instructions (including trying setting the host PC to a fixed IP address, which was not supposed to be necessary), but I am consistently getting a "Broadcast Error" message, which I am guessing means that the utility and the RVS4000 aren't talking.

I have recently purchased a RVS4000 router and am experiencing major downtime.Almost everyday the RVS4000 router losing internet connectivity. I noticed that when this happens I cannot login into the router from my pc which is connected to the RVS4000 network.The only way to restore connectivity is to restart the RVS4000 by disconnecting power and powering back up.The router's WAN is connected to my Cable modem.The RVS400 has two PC connected to it. (port 3 & 4) I have a Cisco 8-port switch connect to the RVS4000 with 3 additional PCs/devices on it.

This is just a tip that we used on our controllers that I wanted to pass along. We were having issues with unwanted access points associating to our controllers. We had a stack of older 1242s that came up missing and hit our network. On way we came up with to prevent this was to number all of our wlans above I'd # 16 on the controller. By default the default ap group allows all wlans from 1 to 16. By starting with 17 we are not allowing any SSIDs in the default group. All if our production access points are in their own ap groups. Any access point that hits our controllers that has not been configured with the correct ap group name will be in the default ap group and will not be servicing any SSIDs.I know there are other ways to set this up but this was a tricky way for us to set it up and see who calls about there wireless not working.

I have 3 computers on my network. The main computer is protected by mcafee. The other computers can not access the public folder on this computer. I know that the problem is the mcafee firewall because when i switch the firewall off the other computers have full access to this folder. This problem started with a mcafee upgrade. I want to keep the mcafee firewall,

Currently running an ACE 4710, which is handling all of our inbound SSL connections and then forwarding requests thru to backend web servers. This all works fine.
My question is this..Right now we are not load balancing any of the backen web servers. But I now have a requirement that should a web server crash or become unavailable I need to redirect that backend connection to another web server.
Scenario is more like I have 2 web servers both serving same content, but I want one server to take all the connections unless it fails, at that point have all the connections forwarded to 2nd server.Is there a way to setup the load balancing where the 1st server gets all the connections until a failure happens ?

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?

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 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 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?

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.

Few months back I had purchased this Router. But I did not use it till last week. Since the time I have installed it, it does freeze often (between 5 to 30 hours).
I can connect to devices within the subnet, but not elswhere. I have to remove the power and plug it back for it to respond. I have updated the firmware to the latest one that was on the Cisco site.

I am trying to configure my RVS4000 to create my church's small network. I want to connect my internet DSL router on the WAN port and also segment my network with VLANs on the 4 LAN ports. I have port 4 connected to a wireless access point which is in VLAN1 for an open wireless network for any church member to access the internet through. I have a church server, printer and second access point on ports 1-3 in VLAN 34. All ports are untagged. I want the devices on VLAN34 which need confidentiality to be secure from the devices connecting to the internet from VLAN1 for open access but both VLANs need access to the internet..
My open wireless AP in VLAN1 has access to the internet on the WAN port.
None of my devices in VLAN34 have access to the internet. I have tried using inter-VLAN routing but that made operation worse so I disabled it.

I work for a company that recently upgraded to a Cisco RVS4000 router in place of a failing D-Link router. I configured the RVS4000 to utilize the same address space as the D-Link previously did (192.168.0.0 Network Address, 255.255.255.0 Subnet Mask, RVS4000 in Gateway Mode with IP Address 192.168.0.1, DHCP Scope from 192.168.0.101 - 200 managed by the RVS4000) before installing it on the network. I powered down the D-Link as well as the cable modem, then all of the workstations in the office. Then, I installed the RVS4000, powered up the cable modem, and once it was ready, powered on the RVS4000.
When devices connect, the RVS4000 is assigning them an IP address in the 192.168.1.0/24 subnet, instead of the 192.168.0.0/24 subnet. I have verified that the RVS4000's GUI is showing the correct settings, but connected devices are not picking up addresses from the correct address pool. In troubleshooting, I went to each workstation, released and renewed their IP addresses, and they picked up addresses in the correct subnet. I thought everything was solved, but the next day, the same problem resurfaced.
I left the DHCP lease time at the defaul value "0", which according to the unit's documentation should correspond to a 24-hour lease period. I suspect this is why I had to renew the clients' IP addresses the next day (today), but I still don't get why the RVS4000 wants to give out addresses in the 192.168.1.0/24 scope. Could this be a holdover from the factory settings?
Additional Information: I did not set up any VLANs on the network and the office only requires one subnet as there are not a lot of devices connected, nor do we need the traffic segragated. The VPN functions of the RVS4000 work fine. Using the QuickVPN utility, I can access the network and resources on the network remotely without issue.

I am having problems with the RVS4000 ver 1. I cannot download files from the web. Firmware is up to date. As an example, if I try to download from pdf995's site, I get a "page cannot be displayed error. If I try to download current files for my flight planning software (like charts, etc.), the download hangs and never completes. I have bypassed the RVS4000 and connected directly to the broadband router and there are no problems. We have a 15MB cable connection.Follow-up - It appears the issue is file size. At pdf995's site, downloading a 2.5MB file works, but the 9 MB file does not. The file sizes for the flight planning software are rather large - 100-200 MB, and they hang as well. Connecting directly to the cable router does not cause this problem. The RVS4000 is set for Gateway mode.

My new RVS4000 (2.0.2.7) connects the WAN via PPoE with dynamic IP which is held at DynDNS and normally I see the RVS4000 via a router-to-router-VPN. That works fine so far, but every "some" days the router looses WAN connection (and with ist VPN). When this happens, last DynDNS-update is hours ago, so it didn`t reconnect. Looking on the routers site, the LAN is fully functional for clients that have got their DHCP-Information. New clients don`t get DHCP-Info (IP-address, DNS), both do not have internet access. The router`s WAN-summary shows, that it thinks to be "CONNECTED" but with empty WAN-IP and DNS entries. Klicking "DISCONNECT" and then "CONNECT" again solves the problem so far. The loss of connection is not the periodic break from the IPC, which is correctly identified and reconnected as configured. I wanted to trace the problem with the log, but there is also a bug. It stops logging at some time completely - neither email-log nor local log, so I never happend to be lucky to hit the point of loss of connection. Also the local log provides a first and next pages, but the next pages are always empty - not really useful.
