Cisco Routers :: RV042 When Updating / Adding Mac Addresses / Table Is Always Sorted By IP Addresses
Oct 8, 2012
In setup for old RV042 (V1), when updating / adding Mac addresses, the table is always sorted by IP addresses. But in the new oneRV042 (V3) I have, even with latest firmware 4.2.1.02 the list is random, thereby increasing the chance of user entering DUPLICATE IP addr with diff Mac addr. That will result in conflict.If the firmware sorts the DHCP entries by ip addresses, user would be able to catch duplicate ip errors even if the system does not flag the errors. All Cisco smart engineers can you all get the dhcp entries SORT by ip addresses.

On the System Summary screen in the Port Statistics table when you click on one of the Connected links the pop open window does not show the IP address of the connected device when using IPv4. Where can I find this?
If the devices are using static IP addresses and not getting them from the DHCP server they do not show in the Client Table under DHCP Status.
If they are know MAC addreses because they have been assigned to static IPs on the DHCP setup screen they will not show up in the Uknown MAC Addresses pop up window.

I've installed RV042 for a client of mine. For next two months everything worked without any problems. The issue I've been experiencing lately is when I assign a static IP address to the PC it won't have internet access. Once I allow it to have a dynamically assigned IP then it works fine. The IP I assign isn't part of the DHCP range.

if possible with the RV042.Primary External IP address uses port forwards for some ports, all okay.I would like to have other external ip addresses assigned to machines on my lan.Basic host multiple web servers, on different IP addresses, using port 80. [code]
From what i am reading, it looks like the RV042 can do this, but I am not real clear what my rules should look like.
I would think my high priority rule for each external IP address would be to deny all traffic first for each machine on the lan.Then create one entry with source 202.x.x.2 port 80 -> 192.168.168.2 ?
How should I set my rules to do this, and what settings should I have on the Nic of the second machine?

Do you know why there are two MAC addresses in iPad's interface table? Only the first digit is changed from a 4 to a 6. MAC address sites recognize one and not the other. I am trying to figure out if I have been networked into a neighbor's security/surveillance system and thus mapping out what is linking to what. I am using IT tools app as well as searching many websites.

We have an issue in which some of our public IPs will not work from outside. We have a couple of subnets/29. We allow traffic via access rules and they point to internal servers (nat to nat). So I requested an ARP table from our ISP router. The table shows that the non working IPs have a differect MAC address than the working IPs. Our ISP blames our equipment (CIsco ASA 5510) for this. I spoke to Cisco support. They looked at our configuration, and tested it. They say our configuration is correct and the ISP's equipment is doing it.
IPSMAC address*.*.*.5*.*.4cd8*.*.*.4*.*.4cd8*.*.*.3*.*.4cd8*.*.*.2.*.*.4cd8*.*.*.204*.*.4cd8*.*.*.205*.*.4cd9
As you can see above, the IP ending in 205 has a different MAC address ending in 4cd9. It should end in 4cd8. This seems to happened randomly with all IPs. Like if I restart the ASA. Some of the IPs will not work, and will show a different MAC address.We then have to wait a couple of hrs for them to start work again.

we have a 3750 and use dhcp services on the switch. every so often we run out of ip's even though we have much less users than the size of the allocated dhcp pool. I've noticed that the dhcp bind table is full but a ping-sweep only shows very few ip's being assinged and used. It looks like the IP addresses are not being released from the table even though I have decreased the lease time to 8 hours.

I have just installed an SRP 527w and it's basic operation is working fine. However, the ISP has allocated (and set up routing for) a range of 16 additional static addresses to the link that I now wish to configure and use, but I am having problems. Details are as follows (ip addresses are fictitious): [code]Extra ip range Netmask: 255.255.255.240From what I understand, these are added as subinterfaces which are bridged off the main WAN interface. However, when I try to add a subinterface by specifying (say) I get an error when saving : [code] The error states "IP Address and Gateway cannot be the same as the netmask".

how do I block IP/Internet Adresses for ALL users without adding the sites manually per user in the Parental Control panel? I want to block a certain IP/internet adress for all users but can't find this feature within my EA6500 anywhere?Is this a firmware bug? Has linskys forgotten that some sites want to blocked for all users and how do I do it all in one?

I purchased 2 RV042's (h/w version 3) less than two months ago. I updated them to the latest firmware (v4.0.4.02-tm (Jul 4 2011 13:30:56)), did a factory reset to make sure I was working with a clean slate, set up DDNS through DynDNS and a site to site VPN between the two. Everything was working great for a month, then the DynDNS accounts expired because they weren't being updated. I reactivated the names on the DynDNS site, and started to monitor the "last updated" date and time. After 24 hours there were no updates according to the DynDNS site. I logged into one of the RV042's, and it said "Dyndns Enabled : Dynamic DNS is updated successfully." This is a stale message from 24 hours ago when I hit save. So I went into Setup | Dynamic DNS | Edit Config and there it also says "Dynamic DNS is updated successfully." I clicked "Save", status changed to " Dyndns Enabled : Updating..." for a few seconds, and then back to "Dyndns Enabled : Dynamic DNS is updated successfully". I refreshed the DynDNS website and it shows the current time (in eastern time, i'm pacfic) as the last time it was updated. So it works when I manually hit the "Save" button. Not making any changed, just hitting "Save". I've let the other RV042 go over 48 hours and it still hasn't updated. So it apears for the time being, I'll have to remember to push the "Save" button once a week to prevent my DynDNS accout from expiring. Does DDNS working in the lastest firmware and h/w version 3? If so, what is the update frequency?

I have an unusual deployment scenario which may require the use of a SRP-521W, the scenario is as follows:Temporary Setup:Cisco 857 As the ADSL router until Ethernet Hand-off is installedMultiple IP addresses delivered on the ADSL WAN serviceCisco 857 put into Bridge Mode and connected to SRP-521W WAN portCisco 521W handles the Authentication and RoutingCheck Point Firewall System connected to SRP-521W LAN-1Check Point Firewall has WAN IP 203.XXX.XXX.XXXCisco UC-540W Connected to SRP-521W LAN-2Cisco UC-540W has WAN IP 203.XX.XX.XX If you understand the above scenario, I am curious if this can be done and if so how? I need to keep the networks totaly separate and the only thing they would have in common is the Cisco SRP-521W.It should also be noted that the SRP-521W Is being used because the ADSL service is only temporary whilst the Fibre Build is completed and the carrier provides an Ethernet Hand-Off, then the Internet service will change to this type of presentation and the ADSL router will be relegated to the dark world of loneliness.I have gone through the router and have been playing around with the settings, the issue Is I have nothing in the LAB work up that can allow me to replicate this environment and test it before deployment... So, how to reduce the amount of trail and error I have to encounter to get it to work.

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.

If there are any small business routers that offer one-to-one NAT? I have several public IP addresses assigned to me by CenturyLink. I have two servers that provide email and web hosting for two different domains. I want to put the client machines on one VLAN (VLAN Z) and assign it a public IP address (to keep server traffic separate). I want to put each server on its own VLAN (VLANs X & Y) and assign each server its own public IP address. I need the router to be able to provide a firewall and port forwarding for each VLAN. I also need to be able to route traffic between VLANs so the clients on VLAN Z can access their email and the websites on VLANs X and Y. I also need to be able to route DNS traffic between VLANs so each server can provide name resolution for their respective domains.
So, is this possible with a small business router or do I need to look at something different? I'm fairly certain this configuration is not possible with my current Cisco RVS4000. What it boils down to is I need a router that is capable of having multiple public IP addresses on the same interface and to forward those public addresses to private VLAN subnets. This would be one-to-one NAT if I understand it correctly..

We have just setup a new RV042G firewall. The customer has multiple public IP addresses and we need to allow RDP access for at least 2 of the Public IP addresses. I only see a way to open ports for the one IP assisgned to the WAN. I temporarily did a one to one NAT for the second public IP to NAT to the private IP but that pretty much opens everything which is not ideal from a security standpoint. How can we setup multiple IP addresses on this firewall?

I currently have the following network structure, which work fine:
The only bandwidth management configuration I did in the Cisco E1000 router is to set the QOS, giving high priority to the 5 SIP Phones mac addresses.
The problem: I purchased a Small Business Cisco router RV016 because the company keep expanding so they will add more SIP Phones and PCs. In the new router configurations, there is no way to do like I did on the E1000 I just want to be able to set high priority to the SIP Phones mac addresses.
What happens when I use the new router (RV016) is that, sometime you dial a number and the phone do a busy signal and indicate "Call failed" or sometime people call in and there is only 3 phones ringing.
I tried port forwarding.. disabling firewall.. SPI.. I tried access rule.. whatever I do doesn't fix the issue.
When I put the Cisco E1000 back everything goes well.
I'm using the latest firmware: RV0XX-v4.1.1.01-sp.bin

The client has a Cisco RVS4000. There are 3 Internet devices need to be accessed from the outside and will use one public IP for one device. I don't see any options to setup on Cisco RVS4000 to do 3 NATs. If Cisco RVS4000 doesn't work in this situation, which router will do?

I have a customer that has an RSV4000 Router. The customer has also purchased a block of 5 usable public IP addresses. I need to be able to assign these public IP addresses to printers either by configuring a static IP on each printer directly or thru IP mapping or some other method. Does the RSV4000 support using multiple public IP addresses and if so what configuration is needed in the router for the printers to be seen by the outside world.

I have an ADSL connection and have configured the PPPoE subinterface on WAN1 (ADSL) this connection has a static IP, and I know that the ISP gives that to me through DHCP however I have 4 or 5 additional IP addresses also provided to me on that same link, and they are not given to me via DHCP.
How do I configure this router to have multiple fixed IP addresses on a PPPoE interface?
I also need to port forward some ports for each of the IP's but I assume this will be easy after i have the IP addresses setup.

Just purchased a Cisco RV110W for our small business. We were told this was easy for us to use and secure enough for our small office and for our travelling sales staff to access our website.
We purchased 2 dedicated IP-addresses, 216.82.5.230 for access to one server, and 216.82.5.231 for access to a second server (these IP-Addresses given are just an example; not real).
These come into the single RV110W WAN port. The two servers are plugged into 2 of the 4 LAN ports.
But the WAN setup page only accepts one WAN IP-Address. So when we put in 216.82.5.230, the outside world can HTTPS into one server, but we don't know how to get them to HTTPS to the second server when the other staff uses 216.82.5.231.
In summary, how to use the RV110W admin panel to forward the HTTPS/SSL traffic from 216.82.5.230 to one server (setup internally on 192.168.10.20), and the HTTPS/SSL traffic from 216.82.5.231 to the other server (setup internally on 192.168.20.20 using the VLAN setup on this router)?

I recently cut over from a WRT54G to a RV120W. I am having an issue where I type [URL] (for a server running on my network) in my web browser while on the internal network and it always comes back with the router login page. Basically it is supposed to go out of the router and then come back in on the public IP address and hit that server. There was a function on the WRT54G called "Filter Internet NAT redirection" which when turned off would allow this to happen. I am not seeing a feature like this on the RV120W

I am trying to configure a BT Business ADSL Router (BT2700HGV) to work in bridge mode in front of a Cisco RV120W router and cannot get this to work.I have followed numerous posts I have come across in configuring the BT router for bridged mode and this has been configured as follows:
ATM Encapsulation - Bridge LLC
DSL and ATM - VPI=0, VCI=38 (also tried VCI=35)
ATM PVC Search - Disabled
Connection Type - Direct IP (DHCP or Static)
Disable Routing - Yes
There are also some other options on the same configuration page for 'Broadband IP Network' (which I have left on DHCP) and also a 'Public IP' which has been left blank. After setting the above options this removes the LAN DHCP configuration, the PPPoA logon details and sets the internal IP address of the BT router to 192.168.1.254.
My understanding of 'Bridge' mode is that this router will now act simply as a modem and configuration details such as logon details and WAN IP address information are configured using the Cisco RV120W router?The configuration of the Cisco router is as follows:
Internet Connection Type - PPPoE
Username and Password set
Authentication Type - Auto-Negotiate (options here are PAP, CHAP, MS-CHAP and MS-CHAPv2)
Routing Mode - Router (Other option is 'Gateway (NAT))' - I have tried both options
The WAN interface on the Cisco router is connected to one of the LAN ports on the BT router. The 'Broadband' light is on the BT router but the 'Internet' light isn't. The WAN status on the Cisco router is 'Connecting'. I am sure I am missing something simple.We have been assigned a range of static IP addresses from BT so am trying to get these working too (x.x.x.24/29 - 5 usable statics), another option available (other than PPPoE) for configuring the WAN interface on the Cisco router is a 'Static IP', not sure if this is the correct option but have tried messing with it, I have tried assigning a static IP from the range given to us (.30 - the router address specified by BT) along with the subnet mask, however don't know what to put as the default gateway, would this be the peer address (but assume that would change anyway), in any case, using the 'Static IP' option does not give an option to supply the BT logon details which I assume is required?
In bridged mode, what is the peer address assigned to, the BT router or the Cisco router?Does the BT router need to be configured with a public IP address?
