Cisco Routers :: RV042 1 To 1 NAT Stopped Working

Jan 6, 2012

I've had 1 to 1 NAT setup for years now with no issues and the other day it simply stopped working.  Rebooted everything, had ISP clear arp on their cable modem yet nothing going.  As soon as I remove the 1 to 1 NAT on the router the PC has internet access.  Add the 1 to 1 back and no out going internet.  The configuration is pretty basic and has not changed.Thinking it could be a hardware issue I swapped it out with another RV042 I have with the exact config, same thing 1 to 1 NATs have no internet access.  Upgraded one of the RV042 firmware to Firmware Version:, had cable modem replaced, spent numerous calls with ISP.  nada
I have found one interesting thing however, any internal machine which is set to dhp works fine, and static ip that does not have a 1 to 1 nat works fine and the last ip in the 1 to 1 nat range works fine.  If I extend the range it is always only the last ip that works.  Even if I add 1 to 1 nats one line at a time, it is always the last entry that works..

Cisco Routers :: RV042 - VPN And Admin Login Stopped Working

May 16, 2012

My organization has deployed 3 Cisco RV042 (v3) at our 3 sites. They have been working pretty well up until about a week ago. One of them continues to route traffic and perform port-forwarding, but the VPN has completely stopped working and I can no longer access the web administration interface. I get the standard login page, but any attempt to login (with correct or incorrect password) takes maybe 5 minutes with a spinning status icon, followed by a blank page leaving the browser at: url...
I have the router logs e-mailed to me, and I can see that the system boots up with Jan 1 2010 as the system date, but it eventually gets the correct date from NTP, so I'm doubting this is causing the problem.
These were working for months prior to this happening, and even a reboot of the affected RV042 does not allow me to log into it or setup the VPN tunnels. I have found similar threads on this forum: url...

Cisco Routers :: RV042 After Configuring DMZ / Remote Management Stopped Working

Sep 30, 2012

I have a 6 month old RV042 with the newest firmware (v4.2.1.02). Over the weekend I configured the DMZ which after a lot of trial and error, was able to get working. Prior to configuring DMZ, I was able to log in with remote management. However now remote management no longer works. I've tried:

- Rebooting the router
- Turning the firewall off/on
- Turning remote management off/on
- Changing the remote management port
The only step I haven't taken is resetting the router back to factory defaults and trying to reconfigure it all again. This router is so finicky I have no faith I'd be able to get my current functionality back again.

Cisco Routers :: WRVS4400N Stopped Working With VOIP Phone

Mar 1, 2013

I have the router for over two years, Present Firmware is V2.0.1.3, I have Polycom phone connected to the router using 8 x 8 VOIP service. The phone was working fine untill yesterday. 8 x 8 tech support suggested getting a different router. I have the same router at home and tried the same phone on my home router - it worked. So, the problem is not the phone but int he router. I tried to call Cisco tech support but found out that the warranty support expired and I need to buy a support plan. Called to buy the support, and gave up after an hours on hold. Left  message.

Cisco Routers :: Configure Two RV042 Working Together

Dec 8, 2011

I tried to configure two RV042 working together. [code] WAN2 of both Router1 and Router2 are unused (unplugged). However, the Host2 can never ping to Host1. So as to Host1. Should I need to configure the protocol binding for all the traffic to the WAN1?

Cisco Routers :: RV042 QuickVPN Not Working For All PCs

Oct 21, 2011

So have a RV042 VPN router that is directly connected to the ethernet port of our comcast cable modem.
If I connect to it using QuickVPN ( from a PC that is connected using AT&T 3G Network it works fine!
If I connect to it using QuickVPN ( from a different PC that is connected using home WiFi (linksys wrtxxx) then it fails. In the VPN log all I see is failure messages for ping.
2011/10/22 15:47:28 [WARNING]Failed to ping remote VPN Router!
If I open a regular command prompt and attempt to ping the VPN router it works so not understanding why the QuickVPN is unable to ping.
how I can troubleshoot this further. Makes me think the RV042 config is fine otherwise it would not work on a 3G connection. Something on the home PC or the home network. Not sure what to check.

Cisco Routers :: RV042 Stops Working During Long Transmissions

Apr 1, 2012

When my RV042 is accessed for long transmissions (svn check out, usually after 20 minutes ) the client receives a message "Gateway not responding, do you want to wait".
When this happens I see the following in the RV042 system log (the first 3 lines of the log below are normal):

Cisco Routers :: RV042 Does Not Load Web Interface / VPN Stops Working?

Aug 12, 2011

We bought an RV042 at the end of June. It is used as a gateway and VPN router. DHCP server is disabled and all IPs are configured manually.Every once in a while (Tuesday night, then Friday night - yesterday, it has hapened once or twice before that) the router appears to restart (see log below) then comes back up with system time of Jan 01 2010. At this point the router will no longer load its configuration page ( and VPN connection to our customer in Africa drops. However, devices behind the router can be reached and can access the internet. The only way to fix this is to power cycle the router at which point everything starts working flawlessly again.The PID VID is RV042 V03 running firmware v4.0.3.03-tm (May 12 2011 21:27:37). Our RV042 is a newer one with Cisco SMB Router branding not the older Linksys branding.
From the log when the router reboots:
Aug 12 22:38:42 2011VPN Log(g2gips0) #141: retransmitting in response to duplicate packet; already STATE_QUICK_I2Jan 1 01:00:05 2010System Logheart : System is upJan 1 01:00:13 2010System LogWAN connection is up : gw on eth1Jan 1 01:00:15 2010VPN Log(g2gips0) #1: [Tunnel Negotiation Info] >>> Initiator Send Main Mode 1st packet 
I looked at the log more and all the usual messages assosciated with VPN being established are there - the last thing in the log before the router coming back up again is:
Jan 1 01:03:49 2010VPN Log(g2gips0) #4: [Tunnel Negotiation Info] Quick Mode Phase 2 SA Established, IPSec Tunnel ConnectedJan 1 01:03:49 2010VPN Log(g2gips0) #4: [Tunnel Negotiation Info] Quick Mode Phase 2 SA Established, IPSec Tunnel ConnectedJan 1 01:03:49 2010VPN Log(g2gips0) #4: sent QI2, IPsec SA established {ESP=>0x575a01c0 <0x6534ae4e 
So it even claims the tunnel should be up but I can never reach anything on the far side.

Cisco Routers :: RV042 Load Balance Not Working Correctly

Feb 8, 2012

We have an RV042 on firmware version and 2 ISPs:
WAN1 = Telepacific T1
1.5Mbps down and 1.5Mbps up
WAN2 = AT&T U-Verse
12Mbps down and 5Mbps up
I have it set to Load Balance, Primary WAN = WAN2
Network Service Detection enabled, only pinging the Remote Host of and set to Generate Log
Bandwidth is set to:
WAN1 = 1000Kbps upstream & downstream
WAN2 = 5040Kbps upstream & 12000Kbps downstream
It seems to pick WAN1 a lot of the time.  Do I have something setup wrong?

Cisco Routers :: RV042 Set Up In Dual Mode And Both WANs Are Working Properly

Dec 23, 2011

I have my RV042 set up in Dual WAN mode and both WANs are working properly.  I would like to configure WAN1 to handle all traffic, unless it fails and then have everything to go to WAN2.  Pretty much what Smart Link Backup does, however with that enabled only 1 of the WANs is live at any given time.  I'd like both WANs to always be live as I'm going to see the second one as a back-door into the network.  Is this possible to do with routing?  I tried setting a routing rule to have everything to go WAN1, but when WAN1 goes down, nothing is rounted via 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]->[TCP/443~443]->[TCP/143~143]-> SSL[TCP/993~993]-> SSL[TCP/587~587]->
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 Firewall :: SSH Stopped Working On ASA5520?

Mar 27, 2012

I can no longer SSH to a primary active firewall. It had all of a sudden stopped working.  However I am able to SSH to the secondary standby firewall without any problems. I did try to regenerate the RSA key on the primary fw, but still unable to connect. The only way I can connect to it is by using telnet.
I ran the "show asp table socket" command and I'm seeing port 22 listening on the primary IP address (not the standby), foreign address is*. I did a packet capture on port 22 on the inside inside, seeing my request hit the fw and then right away a reset back from the fw.
version 8.2.(5)
model ASA5520
I'm hitting a bug in the software version I'm running? Or what else can I check before rebooting the primary fw?

Router Randomly Stopped Working

Jun 22, 2011

Randomly my router stopped working in the middle of the night. I didn't think the issue was with the router so i called the Tech Support people from Brighthouse and they told me to connect directly to the modem so i did that and I had internet. But why would my router randomly stop working, I've had this Linksys Dual N bound router for a year and never had a problem with it. I want to think that its the internet providers fault but I guess I really don't know.

On-board NIC Card Stopped Working?

Mar 3, 2013

I have a toshiba satellite laptop (windows 7) with wireless on-board and an ethernet cable port. Up until last night, both worked flawlessly since I bought the computer a few years ago.

Now, the wireless still works in three different locations I have tried (i.e. three different networks), but the ethernet cable will not work. I thought it was the ethernet connection on the mobo at first, but then after acquiring a USB-NIC connection, I found I had the exact same problem... I can't connect to my router or even direct to the DSL modem using a ethernet cable. I know my system is good since all my other computers (7) work with wired connections, and my laptop doesn't work on other cables on which other computers do. Essentially, it appears that my computer has lost the ability to get an i.p. address using an ethernet cable of any kind. Both the onboard card and the usb-nic cable tell me they are 'working correctly' in the systems/devices/network adapters section. I have tried disabling one while trying the other. I have tried disabling the wireless while trying either, and still nothing.

The main reason I have a dedicated server is to eliminate those shared-hosting issues.For the past 4 years the service has been getting crappier. In fact; this week alone the ftp stopped working, mysql stopped working, and email.It is now to the point I have to move all my domains, mssql databases, mysql databases, email servers and countless files.I have been contemplating to set up my own dedicated server (Mac) and hook it up to my ISP.
