Cisco Routers :: RV120W PPTP Re-writing Source IP
Dec 21, 2011
I have a VoIP application that I'm trying to run over the PPTP VPN tunnel on a RV120W router.
The system is a NEC SV8100 PBX communicating with the NEC soft phone (SP310). The system uses SIP to set up the call and for other signaling information. It uses RTP to transmit/receive the audio stream.
The problem I'm having is that there is no audio stream from the soft phone. The SIP communication and the audio stream to the soft phone works fine. The symptom is: from the soft phone, the remote party cannot hear you, but you can hear them.
I did a packet trace on the RV120W and found the following:
No.TimeSourceDest.ProtocolInfo9489.358957
192.168.1.252
192.168.1.52
[Code].....
As you can see, the Source IP address is being changed from its original 192.168.1.52 to 192.168.1.1. The NEC PBX is expecting the packet to be coming from the softphone, (192.168.1.52) not the RV120W (192.168.1.1). As a result it ignores the RTP packet from the soft phone and does not relay it to the remote party.
Is there any reason why the RV120W is performing NAT on PPTP packets? Can this be disabled somehow?

I'm using Hamachi to connect two computers long distance, but Computer B is unable to open the folder I need on Computer A.Basically I use a program (A point of sale) and it has to update the version on Computer B from computer A, and also has to write client files -on- Computer A... So I'm trying to network them together in order for it to do this.

I would like to set up a site to site VNP connection between 2 RV120W routers, preferably via IPsec.
The problem is that I would like/have to use a 4G modem router (model TINY) which connects to internet in front of the RV120W (on the local side)
I have no problem with that on the remote site that RV120 connects directly to internet via a public IP address on the WAN port.
Local network 192.168.1/24-----RV120W----192.168.100.1—Tiny---Public IP--------INTERNET
INTERNET--------PublicIP—RV120W—Remote local network 192.168.2/24

Upgraded to 1.0.2.6 and all of a sudden SIP devices working over the VPN no longer work. Downgrade to 1.0.1.3 and they work again. My guess is that some ports are blocked over the VPN in 1.0.2.6
I thought the general idea was that firmware ugrades fixed bugs rather than introducing them.
Suggestion for Cisco:- Zip the firmware image downloads, or else have an upgrade process that includes a CRC check, that way at least the poor punter will have an indication if they have been corrupted. I had a subtle memory problem that was corrupting some files. The firmware upload appeared to complete properly and you could log on OK but some of the menu choices resulted in a hang with the "Please wait... the page is being loaded" message. Careful checking of file sizes revealed that the file I was uploading into the router was a few hundred bytes different in size to the one on the website, must have been corrupted during the download. But the upload proceeded normally with no indication of any error. It's a pretty basic safeguard that should be in there as a matter of course with the router performing a CRC check and showing an error if it fails.

I had WRT54G2 and recently switched to an RV120W. I have an Internet accessible camera system connected to my router. Before, this worked fine... there is a dns service (DynDNS.com) that is configured as part of the camera setup. I would then just enter [URL] and I would connect to the cameras. I install the new router (RV120W) and I can no longer connect to the cameras. I do not recall any configuring that I had to perform on the old router.
why the RV120W isn't letting me get to the cameras?

Rx:, recently I have perchase 2 RV120W routers thinking that it must be very easy to setup the site to site vpn. i cannot get my remore office to link to my main office and vice verser.
Scenaro
- I'm using 2 RV120W routers for each site.
- Site A using a subnet of 192.168.10.0 mask 255.255.255.0
- Site B using a subnet of 192.168.11.0 mask 255.255.255.0
I have setup the VPN using the wizard and I got site to site tunnels connected and show as 1/1 Connected (1 user) in the status he IPsec connection status show
--Policy Name: VPNA
--Endpoint : public IP address from my ISP 203.117.222.221
--Packets Tx:145 Rx:0 and Kbytes shows Tx: 29.55 Rx:0
Q1 why I cannot use dynamic DNS naming in the policy setting ? eg: aaa.dyndns.org, I have to use the ip address instead eg: 203.117.222.221
Q2. I cannot connect from Site A to Site B , I can't even do a ping to 192.168.11.1 from Site A. even though it show the Site to site tunnel is coonected.

I've just set up an IPSec VPN between 2 x RV120W which are both behind other router. Here's what we have :
RV120W #1 (192.168.1.254) --- (192.168.1.1) Office Router #1 (PUBLIC IP) --- (((Internet))) --- (PUBLIC IP) Office Router #2 (192.168.2.1) --- RV120W #2 (192.168.2.254)
It works great, tunnel is UP.

RV120W #1 (192.168.1.254) --- (192.168.1.1) Office Router #1 (PUBLIC IP) --- (((Internet))) --- (PUBLIC IP) Office Router #2 (192.168.2.1) --- RV120W #2 (192.168.2.254)
[Code]....
Now, I need to be able to reach the server (192.168.1.100) from a PC on LAN #2 with IP 192.168.2.50. So, I've created au static route on Office Router #2 (192.168.2.1) because of course it doesn't know how to reach private subnet 192.168.1.x. My static route looks like this :
192.168.1.0 / 24 (Destination network) --- 192.168.2.254 (Gateway)
...but it doesn't work, no ping. When I do a tracert to server IP (192.168.1.100) from PC on LAN #2 (192.168.2.50), the result is :
1st jump ---> 192.168.2.1
2nd jump --> 192.168.2.254
...and it doesn't go further.

Model : TD-W8968
Hardware Version : V1
Firmware Version :
ISP :
I've connected a usb hard drive to my TD-W8968 and shared the root folder via storage sharing.When I try to copy files to the hard drive from my computer the transfer speed it about 700 Kbytes/s. When reading from the drive to the computer I get 2000 Kbytes/s.This is way below the 30000Kbytes/s that can be delivered to/from the drive when it's connected to the computer's usb. I've tried several usb drives and for all I get the same results.Is there a way to increase the read/write speeds for the usb connected devices?

I set up a PPTP VPN with an RV220W recently. It was working flawlessly until a recent power outage and now users are getting the 807 error when attempting to connect. I have PPTP passthrough enabled and TCP/UDP 1723 open. As far as I can tell GRE 47 is open as well. Why it was working and is not working after a power outage?

I configured my RV120W (Firmware:1.0.2.6) to count the traffic on my network. I set the monthly limit to 99999 and did not change anything else.So after a few hours, the traffic counter shows 2048 MB for outgoing traffic. This is impossible, because the DSL-connection is too limited in upload to cause this huge outgoing traffic in 6-8 hours. When I reset the counter at night, the next morning the device shows 2048MB again (even if there was no traffic at all, just some clients syncing time with NTP). I did already reset the device to factory defaults and reconfigured everything from scratch.

I have a problem with firewall rules. If I set some rules for open communication and some for closed, so I cannot reorder from the end to begin.
Last rules are at the end of all. So I can only reorder in one pages.(I have about 33 rules = 3 pages of rules)

I need to configure a rv120w in order to make it work at the same time for data and digital tv. The fact is that the set top box for the idtv needs an IP address that will be delivered directly from the ISP. So I need to setup one LAN port that will be bridged to the WLAN connection (the stb will be connected to that lan port), and another port that will be connected to the LAN swicth so that the rest of the network has internet access. I can't see anywhere a way to create such a bridge. Quite disappointing as it's possible to do so on open source platforms such as openWRT..

I have been battling with my Cisco RV120W router and QuickVPN.Running Windows 7 Home PremiumPerformed a fresh install to factory out-of-box install for WindowsRemoved NortonDid NOT perform any windows updatesInstalled QuickVN version 1.2.4.1I have updated the firmware to the latest version (confirmed by cisco)I can connet to the router and have a stable connectionI can ping both the router IP and the shared file server IPWhen I enter the shared file server IP into the search field (e.g. \192.168.100.199) and press enter, I see a connection to "share", so I click on this and then see "FolderName" of my shared files. I click on this folder and I get a timed out error.When I enter the routers IP address into a browser (IE8 as factory installed) I get a timed out error also.In the past, I have installed all important and recommended updates for Windows and still get the same scenerioI have called cisco support and went through router settings, assigned them a VPN username, they log in and can access the files without issue (What the @#$$@#$)Cisco support spent plenty of time with me, but since they could access my network and since I could ping my devices, they had no other suggestions further.
I have this fresh factor out-of-box install. I know this is most likely something to do with my laptop that I am trying to use to connect to the network. I have Frontier as my ISP for home. I don't know if there is anything they are doing to interfere with my connection. I have tried to connect to the network via ComCast as well, with no luck.tell me if there is something I need to tweak in my Windows 7 settings?

I have a Cisco RV120W connected to the internet. I have configured a QuickVPN user on the router, but I cannot connect via QuickVPN no matter on what PC I try (with firewall or without firewal, Windows XP, 7, ...). On the router it says the VPN user is connected, but on the client PC I receive remote gateway not responding. In the logs it says failed to ping remote VPN router. I tried changing all settings I could find on this forum, but the result stays the same (changed port to 60443, deleted all IKE and VPN policies, allowed ping, disabled fragmented packets etc...). None of all the settings seems to get any result.

Trying to setup Three networks all with different IP ranges.I assume I can create a new VLAN and associate that VLAN with one of the four available ports.
Port 1 can have 192.168.1.1 - 254, Port 2 can have 192.168.2.1 - 254 and Port 3 can have 10.0.1.1 - 254.
But the Admin guide I just downloaded is NOT for 10.0.4.10. It shows Networking > LAN > VLAN Configuration.My screens show Networking > LAN > VLAN Membership.
So I am not sure how to make Port 2 associate with VLAN98 ( I created VLAN98 and 99 for the other two networks). There is a membership table that you can Tag or untag for each of the four ports - is that it ?

I recently purchased a RV120W router and I am having a problem selecting n speed under the wireless settings.
If I select B/G/N-Mixed mode then when I go to save the change I get B/G/N-Mixed B/G/N-Mixed in red letters and it does not save. If I select N only then when I go to save it says in red letters N only N only.
It does not matter if I pick 20 only or 20/40. It does not matter if I enable or disable U-APSD. It does not matter if I use the LSB or USB side.
Firmware Version:1.0.3.10 :When I got the router it had an older firmware if I remember correctly, and it would let me change to n speed.

I recently bought Cisco RV120W-E V01 and insall it in my home (with firmware 1.0.4.10). I want to establish PPTP conection from my notebook (when I am not at home) and to access (through VPN tunnel) to all hosts in my LAN (with no port restrictions). I configured VPN (PPTP) users and I can establish PPTP tunnel from client to RV120W. My traffic to Internet is going through VPN tunnel to RV120W and then out on Internet, and that is fine. What is not fine is that I can not access to any host on my LAN, and that is the main reason why I configured PPTP tunnel. It is not clear to me, when I am reading admin guide, what I have to configure to allow only my tunnel traffic to reach LAN hosts.

I'm trying to configure my RV 120W to allow for remote VPN connections by a few salesmen. I tried to set it up through the wizard, but the menu tells me that the Remote Information (IP or FQDN) is assnged when they client connects but I HAVE to put something in there. I tried it with my IP information and can't connect either, but I have a feeling that is my PC's issue with Windows 7 (it just sits on verifying uername and password and then locks up explorer). I don't see anything in the logs about it attempting to connect or anything from my machine- I'm going to work with another but that still doesn't work with the "unknown" IP connection setup.

I recently installed a new 220W with the sole intention of setting up the PPTP server. I got the router installed and working but cannot get the PPTP server working. Also when i configure a block of IP address from my lan for the server it tells me i cannot use that subnet? i have set it up this way with other routers ( RV042 ) with no issues.
firmware is 1.0.0.26

I have a pptp server on my network and am trying to configure my new RV110W so that I can tunnel through to it from outside.
I believe I must do port forwarding for TCP on port 1723 to get those packets going to my PPTP server. PPTP also uses GRE and I don't see that as an option anyware in port forwarding... Does that just work... as a matter of the VPN pass through checkbox being enabled ?
My netgear router would lock up every few days but it under the firewall configuration it had list of services that included PPTP and I just selected that, entered the IP addresses on the outside that I would accept, and the IP address on the inside that the PPTP clients would connect to, and it worked....
I'm thinking it is harder on this device because this device supports actually logging into it.. I am interested in learning more about that technique especially if it is more secure but the way I see it the firewall device can see all of my network and the pptp server I am using is on a file server and limited to those files shared on that server.
