Cisco Routers :: RV220W Blocks Hosts File?

Jun 16, 2012

anything I put into my hosts file, will not go through the Cisco RV220W router. This is part of the set up: << RV220W
192.168.1. 15 << A client machine << Internal DNS with forwarder to OpenDNS ( & + a laptop that's not on the internal network at all.
Now, the client machine and the laptop both have an entry in their hosts files:
From the laptop, I can both browse to, and I can ping it in Xterm.

From the client machine ( which is behind the Cisco Router/FW, I can ping, but I can not browse to it. This is especially strange since the ping goes through the Router every bit as much as the http traffic does, so why is the router giving me a DNS error on that, but the ping goes through just fine?
The hosts file is supposed to supercede any other information from anywhere, so it out to not be a problem for the router either. Yet, it obviously is.
I have tried to disable the internal DNS server as well as OpenDNS and just run the ISP's DNS servers, but no change - I still get that blue DNS error screen from the CIsco router.
Above IP's & hosts are fictitious.
The hosts file doesn't get blocked in a sense, but what happens is that if you have "Content Filtering" checked - even without any rules - the router can not verify that is in fact in this case, since it doesn't exist in the public DNS system.
So, I unchecked Content Filtering and now it works as it should.

Cisco Routers :: How To Manage Port 80 Hosts Via Gateway To Gateway VPN (rv220w)

Aug 30, 2012

I replace our aging rv082 routers with wireless rv220w routers. The gateway to gateway vpn works great, however I am no longer able to manage our print servers port 80 management page. I can ping any host with success, and I can manage hosts that have a port 10000 or 8000 web interface - but no port 80 ones... I had no issues when using the old rv082 routers...

Cisco Routers :: File Sharing Over IPsec With RV220W

Apr 20, 2012

originally had two Netgear FVS318s set up with a VPN tunnel and everything worked as expected. I could connect to the server at the office from a machine at home and browse the files and more importantly do nightly backups of files that had changed at the office over the VPN to the house. The problem with the FVS318s was that for wireless I had to have another device and that the WAN to LAN throughput was something like 7Mbps. Kind of limiting when you consistently get 22Mbps from the ISP.So, I bought two Cisco RV220Ws to replace them with. I started by replacing the one at home and was able to get it going with the FVS318 at the office. The VPN was stable and I had no problem browsing the files on the server as I had already been doing. A couple weeks later I replaced the FVS318 at the office with the other RV220W and the VPN came up fine but I lost all ability to file share between the two sites. I've watched the phase 1 and 2 negotiations and they look good from both ends. =

Cisco Routers :: RV220W Wireless File Transfer Slow At 2MBps?

Jul 23, 2012

I have a RV220W operating in 2.4GHz N-only mode. Channel bandwidth is set to 20MHz, channel to 6 (a site survey shows that channel as completely clear), WPA2/AES. I am connected to a TrendNet wireless bridge. The admin page for that wireless bridge shows a link quality of 100% with a signal strength of 71%. If I select a higher channel (11), the signal strength drops to 51%.
I have a Windows 7 PC connected to the Trendnet bridge and a Windows 7 server connected to the RV220W, both via a 1Gbps LAN port. When I transfer a file from the server to the PC or vice versa, I get a lowsy 2MBps (~20Mbps) transfer rate. That seems awfully slow. I tried channel bonding from 20 to 40 MHz

Cisco Routers :: RV220W - DHCPv6 Prefix Delegation - Editing Configuration File?

Jan 25, 2012

I am trying to configure this router to obtain an IPv6 address from my ISP who offers a dual stack IPv4/IPv6 DHCPv6 Prefix Delegation service.
I did a WAN packet capture to see the type of DHCPv6 packets the router sends to the ISP in order to obtain an IPv6 address and I saw that the router is sending DHCPv6 solicitation packets of type IA_NA i.e. for Identity Association for Non-temporary Address. However, most ISPs that offer a dual stack IP4/IPv6 service, they use DHCPv6 Prefix Delegation in which case the router is expected to send DHCPv6 solicitation packets of type IA_PD i.e. for Identity Association for Prefix Delegation.
I then downloaded its configuration file and saw the following:
dhcpv6c = {}
dhcpv6c[1] = {}
dhcpv6c[1]["renewTime"] = "3600"

So, the option for the DHCPv6 client to perform a prefixDelegation request is disabled. Does that mean that if I set this flag to "1" it is going to work? Well, I edited the configuration file and changed this flag but the router refuses to load it! It complains about the file being changed. How does it know that? Is it computing some type of checksum? How can I manually edit this flag and update the router's configuration?

Hosts File Disappearing?

Jun 7, 2011

We have a modified hosts file on each of the computers here at work. This way we can have multi servers, in multi locations that can all be used by everyone for email & our finance program.However, there is one user who the hosts file keeps disappearing. Over the last 2 days it has disappeared 3 times (at least).The user has ran the symantec corp antivirus (at least a couple of times). All risks found have been quarentined and deleted, ran again and nothing found. Also ran Malwarebytes, which was clean. And ran ComboFix.At this point the hosts file has been fixed after running ComboFix.

Cisco Routers :: RV110W Blocks All Inbound Traffic

May 28, 2013

CE IP - /30PE IP - I had configured some floating static route on the PE towards CE .The routes were installed correctly till PE - CE link was UP as next hop IP was showing as connected .Now the link has been removed and I am receiving a supernet of from PE2 via MPBGP. Although the 1st static route for is showing in routing table, the other 2 ( & ) donot show. I believe that as both the routes and next hop fall under the supernet , the static route is not installing. But I don't know why is this behaviour. I tried to remove the distance 250 from both the routes , but still the static route does not install. I tried this on GNS3 but got the same results .

Cisco Routers :: WAN RV180 ALG Blocks Inbound Sip Messages

Sep 4, 2012

I have a sip gateway connect to the LAN side of RV180 router which has ALG enabled.  I have no problem to make and receive calls but sometime I see the router does not forward the 'Bye' message from the VOIP service provider to the sip gateway.


In the capture frame 4292, a 'Bye' message reaches the WAN of RV180 but it never forward the 'Bye' to the sip gateway with internal ip. All settings in RV180 are default with only ALG enabled. I tried to setup Access Rule or Port Forward but none seems to work.  Not sure if they are over-ruled by ALG? With ALG enabled, is it possible to have individual Access Rule?  If there are conflicts between ALG and Access Rule, which has higher priority?

Cisco Routers :: RV042 Randomly Blocks Traffic To Internet?

Dec 19, 2011

We have a VOIP system from AT&T with T1 internet access. I have a RV042 setup as the default gateway for the network and the router randomly (usually over the weekend loses the internet). I have updated to the latest firmware and have check all logs on the server. When the internet access goes down we can still access the internal network. I have been power-cycling the router and then everything works fine. Is there a known issue with this router radomly blocking internet access in or out? This device should remain working at all times so that our remote users can access the company network.

Cisco Routers :: Static IPs Behind RV220W

Jul 3, 2012

Picked up a pair of RV220W's for a project I'm working on.  I have several IP's available, 4 of which are assigned to/in use by a server behind the RV220W.  All 4 of these IP's are static external IPs.  How I can configure the RV220W so that requests to those 4 IP's get routed to the server.
Prior to purchasing this, I was under the impression what I was trying to do was called one-to-one NAT, but after reading the 'Help' document on the one-to-one NAT page, I don't think this is right.  Emphasis added below: Cisco RV220W Wireless-N Network Security Firewall Help FirewallOne-to-One NATOne-to-one NAT is a way to make systems behind a firewall and configured with private IP addresses appear to have public IP addresses.One-to-One-NAT Rule TableThis table lists the list of available One-To-One NAT rules configured by the user. Private Range Begin: start ip address in private (LAN) ip addressPublic Range Begin: start ip address in the public ip address (WAN IP), Public IP Subnet Mask: The Subnet Mask of the public IPRange Length: Range length maps one to one private address to public address up to the given range.Service: This column shows service to be accepted by LAN Host.The actions that can be taken on One-to-One-NAT rules are:(Check Box At First Column Header): Selects all the entries in the table.Add: Opens the One-To-One NAT Configuration page, to add a new entry. Edit: Opens the One-To-One NAT Configuration page, to edit the selected entry.Delete: Deletes the selected entries.
So according to their documentation, the server in question would need to be configured with a private IP.  Unfortunately, one of the applications I use is licensed via IP address and my understanding is that I cannot use the software with private/non-routable IP addresses.
Is the RV220W capable of not only securing the line (firewall, access rules, content filtering, port trigering & forwarding etc) but also doing what I was hoping to do (keeping the external IP's on the server, and routing appropriately)?

Cisco Routers :: RV220W Won't Allow Web Access Across VPN

Dec 12, 2012

We have 2 sites connected thru 2 RV220W routers via VPN and most things are working fine. I have noticed however, that any device that has a web interface, i.e. our Sharp Copier and our Freenas server, is inaccessible. The page tries to come up but then I get the Cisco "server is down" page generated by the RV220W.
I can pull up the web interface pages if I use a machine on the local LAN but not on any machine across the VPN. The only commonality I can think of is the RV220W blocking that traffic for some reason..

Cisco Routers :: Associate Name To IP - RV220W

Nov 27, 2011

Is there anyway to associate a name to an IP in the RV220W?  I am coming from a WRVS4400N v2.  Folks are complaining that they can't connect, for example via Real VNC, via the PC name any longer.  They have to use the IP address.  In the past I put the names of the PCs in the WRVS4400N when I reserved IPs via MAC addresses (some call this assigning static IPs).  There isn't any place in the RV220W to put the name.  Even when I look at the DHCP list a lot of them show up as "unknown".  I am sure this is a NETBIOS thing but I'd rather fix this in the router as I have always done in the past.

Cisco Routers :: RV220W Just Disappears

Jun 23, 2012

Having a strange problem that just started this week and got worse this evening. I have a RV220W that is feeding my network. The RV220W sits behind a broadband modem and acts as the DHCP for the network and those computers access the internet that way. Anyway, tonight started an issue where the the RV220W just disappears. Becomes unpingable. I recycle power, and within anywhere from 5 to 10 minutes, it's gone. No longer pingable.  Even if I plug a latop directly into it.If I power cycle the RV220W it comes back and I can ping it and access it and its settings. 5 to 10 mins later, I again lose it. Nothing was done. Its been working fine for a few weeks. Had a similar outage last Tuesday, but a recycle of everything brought everything back into line. After I lose connection to it, the lights I expect to be lit remain lit.

Cisco Routers :: RV220W - Very Slow Wi-Fi Connection?

Aug 5, 2011

I'm an IT professional with more than 10 years experience. I have spent last 5 days trying to figure out why the wifi connection to this router is so slow, but still no luck. I'm getting only 13Mbps even if my laptop is next to the router! (wired connection worked ok)
I have tried all sort of setting combinations, 2.4GHz/5GHz; N only/ G,N Mixed;  Auto/20MHz bandwidth; different channels; WPA2 encrypted vs open; disable firewall; wmm enabled/disabled; firmware... no matter what I try, I always get only 10 - 15Mbps speed.
Once I replace this router with my old router, it worked perfectly --- getting 70 - 80Mbps with exactly the same testing environment and configuration.
I really expect this router to offer much faster wireless speed according to this review: [URL]

Cisco Routers :: Workgroup Accessibility With RV220W

Apr 30, 2013

I'm using a RV220W in my home office. Before this router I was. using a Sitecom router which did not cause any problems. I have setup a home network. The RV220W connects to the provider modem. The client components connect to the RV220W. Which acts as DHCP gateway. The DHCP features of the modem are disabled. I have assigned all network client devices to the same workgroup. I have to windows 7 PC's. one of them acts as fileserver. when trying to acces it from the other fixed PC or via a laptop the fileserver is visible but not accessable. I can not open it and access the shared folders.It has worked for a brief moment, but without changing any settings it stop working. I have never had accessability problems with the sitecom router. I have installed the latest firmware and tried rebooting the router several times. I have also started again with the factory defaults.
