Cisco Routers :: RV042 Can't Get Forwarding / Firewall And Client To Gateway VPN

Jun 9, 2012

I'm trying to set up a RV042 to do the following:
 
1) Block all WAN connections, except for:

2) Allow all port 80 connections, and forward to 10.4.20.60

3) Allow all port 443 connections, and forward to 10.4.20.60

4) Allow port 22 connections from specific IP addresses, and forward to 10.4.20.60

5) After a remote client has connected using Client to Gateway VPN, allow that remote client to access anything on the LAN
 
I'm able to do #1-4 above, but I can't get #5 to work. Or I can get #5 to work, but can't implement the restrictions I need in #1-4. Attached are some relevant screenshots. I think the problem is that I have Forwarding rules set up that require me to have a firewall rule to Deny All Traffic from WAN1 (unless I'm specifically allowing it). In the Access Rules screenshot, rule #6 is the problem. If I enable it (thereby denying all WAN1 traffic), then VPN clinents can't access anything on the LAN. However if disable this rule, VPN clinents can access anything on the LAN, but the firewall also opens up all outside connections to SSH, since that's set up in the Forwarding rules. I would have thought that once a remote client is connected using client to gateway VPN, then that client is considered to be on the LAN, as far as the firewall is concerned. Thus a firewall rule (like #6) that is specified for WAN1 shouldn't effect remote VPN clients.

Cisco Routers :: Set Up RV042 As VPN Gateway For Client

Aug 29, 2011

I set up an RV042 as a VPN gateway for a client a year ago. It is running firmware 1.3.12.19-tm (Feb 13 2009 13:03:21). I created a new certificate. When I download the client certificate, It comes as a .zip file. One the can not be opened by a zip utlity (windows, Winzip or 7 zip). It looks like I can just rename the file to a .pem file, but I want to make sure that is right. They were getting QuickVPN timeouts, but that looks like it was fixed in 1.3.13.

Cisco Routers :: Quickvpn / Client To Gateway Vpn Rv042 Can Only Ping Router?

Jan 27, 2012

I am setting up remote access using an RV042 router.  Using quickvpn or a client-to gateway vpn and shrewsoft client,  I can only access/ping the LAN side of the remote router and one machine on the remote network.  The PPTP server and native Windows 7 connection provide access to all machines on the remote network.I have 2 possible reasons for this and would like to find the real reason:
 
1) The remote RV042 is behind another router, and that router restricts access other than the PPTP traffic.

2)  The VPN tunnels other than PPTP only allow access to the remote LAN side of the router and remote machines that have the remote router defined as their gateway in the IP configuration.

Cisco Routers :: RV042 V3 - Port Forwarding And Firewall Rules On WAN 2

Oct 13, 2011

I have a new (about 4 months old) RV042 V3 4.0.0.07 firmware that I am trying to use in fail over mode.  I have a SOHO and I normally use cable Internet connection.  It is quite fast (15 megabit), but not super reliable.  I have added DSL (3.3 megabit) which is five nines (supposedly) but not so quick. 
 
I have a Westell 7500 wireless DSL modem located in the basement, where the telephone lines enter the building.  This gives me a wireless link to the second floor server room through  a wireless router that connects to WAN 2 of the RV042.   The cable modem is in the server room and connects directly to the WAN 1 of the RV042.  The cable works, but when it goes down, the DSL link comes up but does not allow Internet traffic.  The RV042 is set up as a Bridge and I have set up port forwarding to get the cable to work and used similar firewall commands to route the traffic if the router switched over.  I suspect that the problem is in the port forwarding (port 80) or the firewall rules(which are pretty simple) because everything looks like it switches over, but it just doesn't work on WAN2.

Cisco Routers :: RV042 Port Forwarding Stops Working When Firewall Is Enabled

Jun 4, 2013

I have a RV042 router on a single WAN and an internal LAN. I have configured port forwarding as follows: HTTP[TCP/80~80]->10.0.0.6HTTPS[TCP/443~443]->10.0.0.6IMAP[TCP/143~143]->10.0.0.5IMAP SSL[TCP/993~993]->10.0.0.5SMTP SSL[TCP/587~587]->10.0.0.5
 
Everything works just fine when I have the firewall DISABLED. However, when I enable it the behaviour is erratic. 1 out of 10 attempts to connect to ANY port forwarded works. Almost all attempts time out. Notice that this happens even if using only the default firewall rules (which should be bypassed by the port forwarding as I read in other posts).
 
My second try was to create firewall rules manually, overriding the default ones. I tried adding rules from source WAN1 (where my connection is) to ANY and to SINGLE IP's on every port. Nothing seems to work.
 
I don't know what I'm doing wrong, this is really bugging me. I had to turn the firewall off so we can access our servers from outside the office. This shouldn't have to be done.
 
Just found out that my firewall is getting LOTS and LOTS of Blocked - SYN Flood entries. I think this is why we are having trouble with the firewall. Could this be the problem? I have no idea where all these SYN packets are coming from since they appear with spoofed IPs or come from different bots all over.

Cisco Routers :: Does RV042 Router / Firewall Support Port Forwarding From Internet

Aug 5, 2011

I am using an RV042 router/firewall -- firmware v1.3.13.02-tm -- connected to a cable modem.I have one public address (WAN1) assigned by my ISP's DHCP server.All my machines on the LAN have static IPs.  (RV042 DHCP Server is disabled.)I have set up port (80) forwarding to 192.168.1.101 The HTTP port forwarding does work if an http client on the LAN sends a request to http://<public-ip>:80But I cannot get a response if I send a request to  http://<public-ip>:80 from a machine on the WAN.
 
I  did configure Access Rules to allow http traffic (and then tried to  allow *all* traffic) between a single IP on the WAN and 192.168.1.101 The  incoming log table shows a connection is made from the http client on the internet to the correct http server on the LAN, but there is no resonse  from the LAN to the remote client.Is my configuration the problem, or is this feature not supported by the RV042 router? Could my cable modem be blocking outbound traffic?

Cisco Routers :: RV042 Gateway To Gateway Tunnels Not Reconnecting

Apr 11, 2013

I have two Cisco RV042 Routers, they are being used to connect two offices, i have created a standard gateway to gateway connection, fixed public ip addresses on both sides and everything works fine, except when the tunnel gets disconnected, it does not connect back automatically, i have to log into either  router console and click the connect button to get the tunnel working again, this is really annoying since it happens once or twice a day at least.

Cisco VPN :: Linksys WRT54G To RV042 (Client To Gateway) Access

Apr 12, 2011

We recently upgraded from a Linksys WRT54G router to a Cisco RV042 to gain "gateway-to-gateway" automated VPN access. However, we are unable to get "client to gateway" access working.
 
With the Linksys WRT54G we used a "username" "password" pair for remote client authenication. This worked for both Windows and Mac OS X users using the built-in PPTP client. We found we had to set "encryption" value to "none" on the client side.
 
I am confused by the setup screens on the RV042. It looks like I must setup a "tunnel" (VPN->Client to Gateway), there is (VPN->VPN Client Access) where I can enter a username/password, and also (VPN->PPTP Server) where another username/password pair can be entered. I have tried all sorts of combinations but "no love". I am particularly mystified by the (VPN->Client to Gateway) settings for "Remote Client Setup"; the client can be calling in from anywhere and there is an option for "Dynamic IP + Email Address" but I'm not sure how that maps onto the client (do they use the email address as their account name?). I have also looked at defining a "Group VPN" where I am given other options. But nothing works from the client.
 
I just need to come up with some setup that works, that I can document to both PC and Mac users at a miniumum.

Cisco Routers :: Auto / Programmatic UPnP Port Forwarding For RV042 And E4200 Routers

Jan 24, 2013

I have RV042 and E4200 routers . I tried the manual UPnP port forwarding using Rv042  router and was succesful ( by typing 192.168.1.1  in the explorer and  logged in using user name and password )
 
I am using a linux embedded system  whose  Internal IP ,Internal port  are mapped  .This system is connected to one of the LAN ports    
 
I want to try auto UPnP port forwarding both for  RV042 router and Linksys E4200 routers 
 
After  enabling the Upnp option only  and logging out ,Can i add a port mapping entry in this router without logging in  using  a  C++ program  which runs on  linux embedded system .

Cisco Routers :: RV042 - Port Forwarding Using Both WAN 1 And 2

Apr 19, 2013

Currently I have the RV042 router working in a dual WAN set up, it is configured to accept connections on numbers of ports like 80,443, 25 and forward them to a local ip.

The problem is this only works with WAN1. Is it even possible to forward ports for connections coming in over WAN2?

Cisco Routers :: RV042 502 Bad Gateway CGI Was Not CGI / 1.1 Compliant

Mar 31, 2013

I've got half a dozen RV042 routers in various locations.  They are running v4.0.0.07.  Seemingly randomly, I got the 502 Bad GatewayThe CGI was not CGI/1.1 compliant. error when attempting to log into the web interface with google chrome (same with IE too).  This happens from the LAN side.  I actually didn't notice it until my Opsview monitoring software threw up a critical when it didn't get an http response. The router is otherwise actually working just fine.Since the first occurrence, more of my routers have developed the same error.
 
I've tried different browsers, clearing caches, though I'm not surprised those efforts were fruitless, as there is clearly a problem even when no browser is involved (nagios).  The nagios http check also returns a 502 Bad Gateway.

Cisco Routers :: RV042 QuickVPN / Gateway Not Responding

Jun 28, 2011

I have router Linksys RV042 v1.2 with latest firmware Version: 1.3.13.02-tm. And I'm using QuickVPN v 1.4.1.2. I've setup VPN connection with values, below: But every time I'm trying to connect to router by VPN it always popup a window "Remote Gateway not responding".It occurs when I'm trying to connect to VPN behind other router, when I'm connected directly to Internet the connection is established.But I'm connecting to other networks using VPN and it's working properly (behind the same router), so I think it's problem with RV042 configuration but I don't now weher.

Cisco Routers :: RV042 V3 And SBS 2003 RWW - Why To Configure For Port Forwarding

Sep 14, 2011

I have tried replacing a loaner RV082 V2 with an RV042 V3 router with firmware 4.0.4.02. All worked well, including the site to site VPN. However, in spite of the fact that I have ports 443 and 4125 forwarded to the server (192.168.2.10), we are unable to connect via RWW. There is no such problem with the RV082. What is different with the way we configure these V3 routers for port forwarding?

Cisco Routers :: Using RV042 As Layer 3 Clear Gateway For Comcast EDI

Feb 18, 2013

Comcast installed a new fiber 10M EDI internet connection in our facility the other day and found out it is our responsibility to provide a layer 3 gateway to map the internet connection to the 14 public IP addresses they assigned to us.  We are using RV042 for our existing networks with a T1 we had.

Another way to circumvent this limitation is to foward a request to the router from the LAN port 80 to a LAN IP, something like:

Cisco Routers :: RV 042 - Client To Gateway VPN Set Up

Nov 8, 2011

I have a RV042 and I am trying to setup a Client to Gateway VPN for about 12 to 15 remote users. These users travel a lot and need to connect to the server. I have never setup a vpn and have looked at the manual and set it up like it says to. I installed the Quick VPN client on the remote computer and copied the certificate to the remote computer.
 
I am having two problems.

1. When I run the client on the remote computer and try to connect it tells me the cert is not installed on the local computer. (it is copied to the root program directory C:Program Files Cisco Small Business and the sub directory, C:Program Files Cisco Small Business Quick VPN Client. 
2. I can continue and it acts like it's connecting but it does not. If I look at the router VPN summary it shows that I connected for only a brief time.

Cisco Routers :: RV042 - DHCP Giving Out Wrong Default Gateway And DNS Server

Oct 3, 2012

I have a RV042 router. The problem that I am having with it is that the DHCP is giving out the wrong Default Gateway and DNS Server. There is no option to change the DHCP server IP on any of the settings pages on the router. I am begining to think that there might not be a way to do it.  I see that there is an option for the DNS under the DHCP page but the Public IP that is being handed out is not the one on that page. I also have 2 WAN connections hooked up as well a DSL link and a Cable link (the cable link is the primary one).
 
The following information is provided in an effort to resolve this issue:
IP of Router 10.0.0.2
IP of DHCP Server (the one that is being handed out):10.0.0.1
IP of DNS (the one that is being handed out): 10.0.0.11
 
What I want to it be.
IP of Router: 10.0.0.2
IP of DHCP 10.0.0.2
IP of DNS 10.0.0.2
