Cisco Routers :: RVS4000 Won't Get WAN DHCP Address

Aug 1, 2012

I just tried replacing a cheap domestic router/switch with an RVS4000 V2 on our work network.  This has a WAN connection to a cable modem for internet access via a dynamic IP address.
When I first connected the RVS4000 it got a WAN ip address via DHCP of  This is the type of IP address we get when there is an upstream problem with our ISPs cable network, and sure enough we had no internet access.  The RVS4000 was set to use DHCP on the WAN interface.  So I logged a support call with our ISP but they said there were no problems at their end.
I then swapped the RVS4000 out for the original router.  This worked fine and got a WAN DHCP address of as it should.  Swapped back to the RVS4000 and back to the same problem of getting a 192.168... address.
So, I downloaded the latest firmware from Cisco, which was V2.0.3.2 and flashed the RVS4000.
I then tried again connecting the RVS4000 to the cable modem but this time it would not get any WAN DHCP address at all.  On the Status/Gateway page of the web interface it said that the WAN interface was down.  However, on the front panel there was a yellow light indicating a live connection on the internet port.

Cisco Routers :: RVS4000 Is Not Renewing DHCP Lease In Auto Mode

Jan 25, 2012

my RVS4000 is not renewing DHCP lease in Auto mode. Connection lost after 24 hours.
WAN Internet interface is physically connected to cable modem - Motorola SBV6120E. Setup as DHCP server. Cisco RVS4000 is obtaining DHCP public IP without any issue, the problem is that the connection drop every 24 hours and I need to release/renew DHCP each day to be able to communicate after 24 hours. After I loose connection I need to release DHCP, the WAN interface goes down and I need to renew DHCP then. I receive the same IP address and connection is againg UP and working.
tried to load new firmware  and also setup the router with default configuration, but without any change. as there is no auto-reboot function, it is really annoying to log into managment interface each day. I also loose remote access after 24 hours, so I am not able to access the rotuer from outside. My local provider do not support static public IP on WAN, therefore I have to use DHCP.

Linksys Wired Router :: RVS4000 Does Not Renew DHCP On WAN

Jan 24, 2011

I have an RVS4000 located at my office.  A user of mine also has one at their house.  We have created an IPSec Tunnel between the 2 of them and have them successfully communicating between the 2 networks with no problem.
The problem I have is if I make a change on their end and the router needs to reboot to apply the changes, the WAN port never renews it's DHCP address.  The end user must unplug the unit, plug it back in and then the system comes back up with the correct WAN DHCP address, and the tunnel is connected automatically.
I beleive they have the newest firmware ( but I cannot confirm that right now as the unit is down.  I bought the 2 of them at the same time - my unit at the office has the firmware so I am assuming the users does as well.

Cisco Routers :: RVS4000 ACL Modification Bug

May 16, 2012

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!

Cisco Routers :: Two RVS4000 Don't Connect To Each Other

Sep 4, 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.

Cisco Routers :: Implementing QOS Over VPN Between 2 RVS4000?

Mar 15, 2012

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.

Cisco Routers :: RVS4000 VPN Setup?

Nov 11, 2012

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 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 Is there any routing or NAT-ing that I need to do on our router?

Cisco Routers :: RVS4000 IP Based ACL And NAT?

Aug 8, 2009

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

Cisco Routers :: RVS4000 - ISAKMP Nat

Sep 13, 2011

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

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 ?

Cisco Routers :: Using RVS4000 V2 For Internet And VLANs?

Mar 9, 2013

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.

Cisco Routers :: RVS4000 Not Distributing IP Addresses?

Jan 21, 2013

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 ( Network Address, Subnet Mask, RVS4000 in Gateway Mode with IP Address, DHCP Scope from - 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 subnet, instead of the 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 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.

Cisco Routers :: RVS4000 Cannot Download Files From Web

Oct 31, 2010

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.

Cisco Routers :: RVS4000 Looses WAN-connection

Aug 18, 2011

My new RVS4000 ( 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.

Cisco Routers :: RVS4000 - VPN DynDNS Behind Firewall NAT

Aug 15, 2012

The local router is behind a fiber firewall/router; the rvs4000's ext ip is thus, not visible from the net.  The firewall/router is a dyn ip, with a dyn dns name mapping to it.  The remote (some NetGear thing) is also dyn dns, but it is not behind a firewall.
I want to cook a vpn from the local lan subnet to the remote lan subnet.
It worked fine when both ends were NetGear.
I think it would be ok if somehow I could thell the rvs4000 that the local Security Gateway Type be just FQDN; it can't be IP+FQDN because the remote end doesn't know anything about that kind of thing; it can do IP or FQDN or a couple other confusing things.

If there's any way to just prevent all traffic from an IP address range on the remote site, that would also do.

Cisco Routers :: RVS4000 VPN Behind Adtran Router?

Sep 5, 2011

So, I'm trying to set up a VPN tunnel between two sites.  Site A has a RVS4000 as the router to the internet.  Site B has a Adtran NetVanta 3200 to convert a frame relay to ethernet, so I can't replace the Adtran.  How do I set this up so I can create a tunnel between the two Cisco routers? I have static Internet IP addresses for the Cisco at Site A, the Adtran and Cisco at site B.  I have configured the two Ciscos to set up their tunnel and I've been able to establish the tunnel between my house (where I put Cisco B in place of my home router as a test) and the Cisco at Site A.  So, I know my tunnel settings are ok (with the exception of IP address changes).
1.) put the Adtran in bridge mode and use the Cisco as the firewall, DHCP, etc.  No clue how to do that.
2.) put the Cisco in a DMZ set up on the Adtran.  If I do that, it wouldn't really give me access through the VPN to the network, right?
3.) set up static routes between the Adtran and the Cisco?  static using the internal IPs or the external ones?
I'm not concerned about Site A since I know the internet works there and the VPN tunnel settings are easy enough to change once I actually get the internet working with the two router combo at site B. [code] I don't care which one does the firewall, NAT, etc.  To me it would seem easier to have the Adtran send all traffic to the Cisco, then let the Cisco do the rest (VPN, firewall, DHCP, DNS, etc.).

Cisco Routers :: Can RVS4000 Be Used To Bridge Subnets

Dec 10, 2012

At the small church I attend, and where I'm the IT guy, we have an RVS4000 router which has worked well for us including the VPN capability. Our internet connection is through AT&T (not my choice) and last week we had to switch from DSL to U-Verse because AT&T is doing away with the former.

Unfortunately as part of this switch, the old modem was discarded and an NVG510 installed. The NVG510 is a combo modem/router. But since it doesn't have VPN capability and is not as good a router all around as the RVS4000 (even though the 4000 is an aging device), I am trying to run both.
I finally figured out how to set up IP Passthrough on the NVG510 so now VPN is again working to the RVS4000 so that's not an issue. We do have a couple of PCs that are in a room where no wired connections are possible so they are using wireless. But they are not very close to the wireless antennas so they don't have the greatest throughput. The NVG510 does have wireless capability and is physically located to where it would provide a much better signal. However, the NVG510 will only use a 192.168.x.x subnet and our LAN is setup for 10.x.x.x. I'm not about to change the LAN as it runs a Windows domain with enough equipment that I don't want the exercise of changing subnets.Can the RVS4000 be setup so that it will route domain traffic between the 2 subnets? As it is now, connecting a PC to the 192.168.x.x subnet on the NVG510 allows it to have internet access but it can't access domain resources on the 10.x.x subnet. I don't understand networking well enough to know why this won't work. I know it can because when I worked for a large corporation, they had different subnets that were routed so that PCs on one subnet could be on the same Windows domain as PCs on another subnet and all access resources on both subnets.
The RVS4000 may be capable of doing this but my limited knowledge of networking (I know servers, not switches, etc) means I'm not sure of what I see on the router to know if it can do it or not.I'd be appreciative to know first off if the RVS4000 can do it, and secondly if it can, then how to set it up. I've worked with the RVS4000 since we got it 3+ years ago so I'm fairly familiar with it, I just don't know the rest.
