Cisco Routers :: RV082 - Blocking Of DNS Request
Jun 7, 2010
I have an RV082 (running 2.0.0.19-tm) set up as the gateway to the Internet on my home LAN, and connect to it through several switches / hubs around my house. Randomly, and from various connections around the house (which are all plugged in to different ports of the RV082), a Web request will fail to load, giving a "Server not found" error in the browser. When I look at the log in the RV082, it says, "Connection Refused: Policy Violation".
It seems to be just blocking the DNS requests - everything else appears to go through normally. For example, I get the message "Looking up domain name.com" in the bottom corner of the browser and the request fails, displaying the Mozilla "Server not found" error page. When I click the "Try Again" button the page, it goes through just fine and everything works.
I don't have any services running behind the firewall, and do not use the VPN settings. Here are my current firewall settings:
Firewall : Enable

Is blocking echo request to prevent ping sweep the same as having a firewall in stealth mode? And how could someone ping sweep from outside if you had a firewall at all?

At this moment (firmware 1.0.3.5) the router has no IPv6 firewall and therefore when used in a typical dual stack IPv4/IPv6 network it has no protection regarding IPv6 traffic. Hopefully this will be fixed with a firmware update before the World IPv6 Day on the 6th of June 2012.

I want to pass my client VPN request to MS Win Server 2003 - on FW I forwarded port for PPTP service to my server address, but on client side I get an error 619. On Cisco RV120W I have Site-to-Site VPN tunnel which works fine, PPTP server on Cisco is disabled. What should I do to pass VPN request to my LAN server to handle it?

We're getting the following message in the logs when we ry to connect: encrypted Informational Exchange message is invalid because it is for incomplete ISAKMP SA
One of the router is a V2 and the other is a V4 if that makes any difference.

We have an RV082 setup with WAN to the internet and LAN IP of 192.168.188.1.If I add a static route like so:
network: 192.168.166.0
mask: 255.255.255.0
gateway: 192.168.188.2
hop count: 1
interface: LAN
The device with IP 192.168.188.2 will be connected directly to one of the LAN ports on the router.Will that work to route, trying to get to 192.168.166.0 to the IP of 192.168.188.2?It just seems odd because the packets would hit the router then go back out through the LAN port.

I have a Meraki Firewall that sits behind my Cisco RV082. The Meraki is setup to run a VPN connection with my server but I am having problems passing the VPN traffic through properly.
I have 2 Uverse Internet Connections that the RV082 using load balancing so that they are shared. I have 10 static IP's.
I am trying to come in on one of my static IP addresses throught the Cisco RV082 to the Meraki and after doing a capture on the meraki it appears that it is starting to receive data to intiate the VPN connection but when it sends data back to the VPN client machine it never makes it.

I have reset my RV082 router (both wit the reset switch and the factory default wizard) and run the setup wizard but regardless I can't connect to shaw.ca which is my service provider. I notice that if I use http://192.168.1.1 the browsers (IE & FF) default to https://192.168.1.1 and then I am prompted for a certificate. I can enter if I ignore the request but after getting in I simply cannot connect to my ISP.

I just set up a new Linksys/Cisco RV082 router with the intent to get VPN working from outside the building. I have gone through the setup and while everything looks good, I have not been able to connect yet. I have tried everything that I know how, and am now hoping to get the answer from some pros.
Here's my setup. We use Comcast Business class internet. The modem is plugged into WAN port 1 on the RV082. I'm using the router as a DHCP server, that is working fine. My local subnet is 192.168.0.0/220
Right now all I want is to be able to log in as a client using QuickVPN. I set up one user and a client to VPN tunnel using the router's config page. Here's the settings I have:
Tunnel Interface is setup on WAN1, checkbox is enabled.
Local Group Setup
Local Security Gatewaytpe: IP Only
Local Security Group Type: Subnet
[Code]....
It seems like something is blocking the connection, but seeing that I have tried this after disabling the firewall completely it doesn't make sense to me. I also went into the config page for the modem and set up the router as a DMZ. I have also tried connecting with the client built into Windows 7, but that doesn't work either, I just get "connection failed with error 619"
I have the port in QuickVPN set to auto, but have tried both 443 and 60443 with same results.
I ran a port scan at [URL] and it shows I have 3 ports open...80,443, and 1723

I have a VPN tunnel from one RV082 to another, first router has IP range of 192.168.1.0 and the second one has range of 18.18.18.0, the connection works fine, here is where the issue starts, I am at a PC in the 18.18.18.0 network and I ping an IP in the other one e.g. 192.168.1.50 and it pings fine, but when I try to RDP into it or do anything to it I get no response, is it a firewall issue? Is it a NAT issue? I am at a loss, now that IP i mentioned does have RDP enabled and working because it is being port fowarded in the 192.168.1.0 router and I can access it through the public IP.
Also a workstation with a static IP 192.168.1.18 I can ping it if im in the local network but if I am in the remote one I cannot at all.

we have an RV082 router that a few days ago started restarting itself after normal usage.The simpton is that when people come to office, starting using the Internet the RV082 resets. It stays online for 3 to 12 minutes and then it resets again.
clicking on Reset to Factory Default in the web interfaceafter the reset, I confirmed that it was reset to factory default I reset it again using the reset buttomre-configure the RV082 manually.I also tested with another identical rv082 (hw version and firmware version) and after doing a backup of the config of the original rv082 and restoring it in the new rv082, the same problem happends.

I have an RV082 10/100 8-Port VPN Router and have configured the NAT table to allow for remote users, however I've run into an issue. It seems like there is a limited number of entries that you can put in the table,10, and I need to configure about 5 more IPs. Any way to expand the NAT table, or alternatively recommend a different router. I would also be willing to add another router to the network, but I have little experience doing that.

Just purchased a RV082 and once I switched a bunch of users over to it I can no longer access the web admin section. I have tried using both IE and Firefox and have used multiple workstations. I get to the login screen but it doesn't get any further. I am running the latest firmware v4.0.4.2-tm. It works for a while then just stops. The only fix is to turn off the device and back on and then it starts working again.
I've seen this issue on other small business cisco devices and had to stop using this because of this issue and switch to a higher grade cisco product but was hoping that this particular issue would have been resolved now across cisco's products.

I just migrated our office network router to a RV082. While configuring it, I came across three problems:
(1) From our ISP we have four public IP addresses which I want to make use of for outbound traffic. With the previous router we used we could configure LAN IPs(ranges) to map to static public IPs. Does RV082 support this? I could not find an option for that at the web-interface. From what I understand the 1-1 NATing only goes both incoming and outgoign ways and actually is 1-1 and not the many-to-one I am looking for.
(2) How is it possible to configure incoming port forwards to use a specific WAN interface? Will it always be the primary WAN interface?
(3) Does the telnet access provide more configuration options? I could not log in to it with the same user credentials as with the web-interface.

we have a RV082 and have the DMZ option enable for a range of IPs within the same subnet of WAN IP and this works great. I have another range of Public IPs from our ISP that is not in the same subnet of the WAN IP and do not see a way on the RV082 to include this 2nd bank of Public IPs in the DMZ. Our ISP internet feed plugs into the RV082 WAN port and we have a switch pulgged into the DMZ port of the RV082 that is used to connect the public devices in the current DMZ. Both banks of Public IPs from our ISP come over via the ISP internet feed plugged into the WAN Port. My question is, if I cannot configure a DMZ rule to allow this 2nd range of Public IPs to "travel" to the RV082 DMZ port.

We recently moved our network over to RV082 router and its working great, well now we want to take advantage of VPN for our sales staff.
I was able to setup the VPN and using a PC at a remote office I can launch the quick connect and it connects right away, RV0 even shows the user connected. However the user cannot ping anything on our network via name or IP, connect to any resources, etc...
My understanding was when the client VPN would connect the user would get an IP from DHCP (this is on our Server 2008 DC) and they would be using that address, but when I run IPCONFIG on the client PC they just have there standard IP from remote office.

I'm planning to buy a few Cisco RV082's for remote offices and using them to connect to main office Cisco 2851 site to site vpn. So I guess, simple site to site vpn will work without much problem, but I wonder, will backup vpn feature work as expected on backup WAN channel and how should I configure it on the IOS side?

The RV082 is a great unit, however when VPN clients connect the QuickVPN Client has a setting to use the Remote DNS settings of the RV082. The RV082 has no way of linking or using a user-defined DNS. I have an internal DNS Server that I would like the VPN Clients to query on internal name lookups (kindof the point of having client vpn, so they can access internal network shares etc. On the diagnostic page the ping and name resolution can only check external DNS and internal IP's. Wouldn't it make sense to at least make the RV082 aware of internal DNS Servers? Then the Ping and DNS lookup would be able to test both zones? Is this something that can be looked at by Linksys Developers for this product? The WRV210 (a cheaper and lower level model) has this functionality.

Experiencing a strange issue with v3 hardware. After a short period of time, I cannot log into the web administration - either locally through standard port or remote through non-standard port get login prompt, enter correct username & password, page refreshes with blank background and first page (status?) never shows.power cycling the router restores access to the web administration page, for an uncertain period of time before it barfs again.
I was running older firmware, updated to newest 4.2.1.02 (?) and same problem. Only thing that is better is the internet didn't completely lock up when I tried to access the administration page, like it did on the older firmware.

I have 2 ssid signals setup at my workplace.
the 2nd one is for all guests and it's isolated from the lan+trusted(1st one) with a vlan feature.
the 1st one is for all trusted devices over wifi. the wifi channel is setup to allow mac addresses of the two asante security cameras. the cameras upload videos to an ftp on my server. the two will connect to the router at first, I can ping them or see them in 'my network'. give it a little time and they disappear. then I have to power off/on the router or the cameras to make them work for a few minutes. the process repeats.
the cameras make lots of connections to the ftp server. I'm suspecting they're flooding the router and it blocks them. occasionaly they will come back for a minute or two and disappear again as if blocked/unblocked.
I added their mac addresses in hopes of making them 'trusted' devices. I've tried them on both ssids. I checked and unchecked firewall/security checks and icsa settings. all other devices I tried, multiple phones and laptops work without problems on both ssids and they don't get blocked.

I have a fibre connection on the dedicated WAN which was working perfect until someone somewhere cut through the line. The SA520 fell over to the Optional WAN port which is basic ADSL line which is connected. Logmein client is online too.
But it refuses to browse webpages, appears to be a dns issue or firewall or both.
I have added the ISP dns addresses into the forwarders on my server.

I have an RV082 for use in our office. I wanted to create a public acess point on a different subnet/vlan and so configured port 8 of the RV08 as VLAN2. When I plug a laptop into this port it immediataley gets an IP address from the DHCP server on VLAN1 and can communicate with the rest of the network.I thought the whole point of the VLAN option was that this shouldn't happen - what I've incorrectly configured?

I have an old RV082 that I suppose has failed. The red diag light on the front panel is lit and nothing works. I've already replaced the unit, so I don't really need to fix it. Here's my issue: the setup on the old unit was pretty complex with a number of port forwards and other non-default settings. I'd like to recreate those items on my new router, but they were never written down so I don't know what they were. I've tried to connect a computer to one of the LAN ports, but they're all dead. Is there any way to get at the configuration page?

I am setting up a SBS 2011 Essentials sever using a rv082 router. I have a decent understanding of how everything is suppose to work, but execution has been sloppy. My aim is to set up a central storage location, back up services, remote access and VPN. Yesterday I had set up dhcp and dns roles on the sever, configed port forwarding and firewall setting on the router, at that point I was just bouncing around everywhere trying to get stuff to work, clearly not the best way I know. Before I left I reinstalled sbs for a couple of reason, along with resetting the router to default.
