Cisco WAN :: 891 NAT Stops Working And Translations Don't Appear In Show IP
May 17, 2011
I have a problem with configuring brach router 891 (with IOS v15.0(1)M).I want to connect to HQ via EasyVPN connection (split-tunnel) and allow the local traffic to go directly to the Internet via NAT (PAT).When the VPN connection goes up, NAT stops working and NAT translations don't appear in show ip nat translations. When the VPN connection goes down, NAT begins to work again.
We have: ASR1000-RP2 ASR1000-ESP40 ASR1000-SIP40 SPA-10X1GE-V2 SPA-10X1GE-V2 ! Kiwi Syslog Server
ASR performs the function of ISG. The number of subscribers until 10000. This number is constantly growing. Because of the economic address space subscribers surf the Internet through NAT.
Now the task to keep logs of all translations or binds. Need to store the information about what time, certain internal IP address using the external IP.
I've tried: ! ip nat log translations syslog ! logging trap debugging logging host xx.xx.xx.xx transport UDP port xxx no logging console (so as not to load the CPU) !
Error stopped publishing but logs do not come. I think of the huge number of translation per second, it can not send them as fast. How can this problem be solved or otherwise obtain and store information about a translations?
i have a 876 Router, connected to the Internet and a VPN. From inside i would like to pass all traffic destinied to 192.168.0.0 255.255.255.0 to the VirtualPPP IF and al the other to the Internet (vlan2) I have created this rule, but after applying ist works only for about 30 to 60 seconds. after that only the Internet reachable. Everytime i do a clear ip nat trans * both Interfaces will work für 30 to 60 secs again...
I have a cisco asa 5010 where, during the process of configuring, the outside ports become down/down. The /0 port won't even reactivate after cycling power on the unit.Port /1 is the inside interface and it is not affected by the problems.I switched the outside port to port /3 and it worked for awhile then it stopped working. I switched it to Port /2 and the same thing.Port /2 and Port /3 are on after a power recycle but shut down completely (down/down) during the reconfiguration. It seems like a hardware failure, but I'm wondering if it could be anything else.
I recently setup a site to site vpn between a asa 5510 and router 1921. It was working great all night and this morning. When traffic stopped rolling through for a few hours the tunnel shutdown. I checked the router using cisco configuration and tells me the tunnel is up. When I check the asa it does not show up in the active tunnels. Any know what would cuase it to drop? and if so what can I do to avoid it.
i've an Cisco ASA 5510 with Security Appliance Software Version 8.0(2), in this ASA i've many L2L tunnels to this ASA, anda sometims new tunnels can't connect, the older tunnels still ok and working, yesterday this situation occured again and i've tried to clear all ipsec tunnels and try to reconnect again no one cames up again. At the time of this situation memory usage was about 78% and CPU is was around 5%. I've made a reload without changes and the situation returns to the normality.
At the time of the fail i've collect the outpu from debug crypto isakmp 255, the outpu was in the annexed file.
I find are steps to turn on SSH access. I have quite a few customers with ASA5510's installed. SSH is set up and working fine on every one. After a period of time, you are no longer able to SSH into the firewall. Using Putty, it just sits there on a blank screen without giving a "denied access" message or a login prompt. Rebooting the firewall will solve the issue and SSH access works again. Today, I had a customer with and active/standby configuration where I had to reboot both of them to be able to log in. Most of my customers are on 8.2.software as most don't want to reconfigure for the new NAT, etc.
I'm sure others have seen this before since it appears to be occuring on almost every ASA that I have access to. Is there any fix to eliminate this or is there something that can be run from the ASDM that will grant SSH access again without just doing a reboot?

I have a Asus n55s. The wireless acts very funky. It sometimes disconnects and stops working. Sometimes, it will stop detecting any nearby wireless networks altogether. Then I have to enable and disable the wireless functionality until it starts seeing nearby wireless networks.
I've been having this problem with my laptop's wifi for a while now and it's been getting a little out of hand lately that I can't deal with it anymore. I asked some friends and they seem to have the same problem too but not nearly as often as I do. Every so often, my laptop's wifi just stops working so I turn it off and then turn it back on and it starts working again. My friend says it happens very rarely to him but for me just today it happened 2 times within 10 minutes
I'm having is that every few hours my TCP/IP protocol stops working. The modem lights remain normal but I can't connect to anything. The only thing that works on the internet is traceroutes at the command prompt which function normally. The solution is that I have to reboot and then everything returns to normal until a few hours later when it happens again. There are no error messages on any of my browsers. The page just goes white immediately. When I try to retrieve my email, I get a message about the TCP/IP isn't working.
On Windows XP, my integrated NIC stops working after hosting a server. The server starts fine, ports are forwarded, firewall is down, modem is fine, but when I receive a connection, it shows they have made a connection, but then they drop, as do I. I can't browse or ping anywhere. I have to physically disconnect, then reconnect the ethernet cable to the port, or restart the computer. Upon ipconfig, the adapter is set with the Windows default ip (169.x.x.x) and cannot be /release'd or /renew'd.
It's fairly hard to explain what happens but basically, say I'm playing some type of online game, all of a sudden anything server sided such as HP amounts, damage amounts, etc. just disappears but the animation runs fine such as attacking being hit, etc. All of a sudden it'll jump forwards and I'll take any damage and do any damage that had been happening until the issue started. This happens constantly and it's really frustrating but on top of that my internet will slow to a crawl..Say I'm trying to send a message on Skype, it won't send for the longest time and I won't be able to recieve any or even open a new webpage until the problem fixes itself.'ve looked around a bit and thought I fixed the issue, I'm on wifi and multiple devices are connected but not always in use, and the forum I found suggested an ip conflict and said to open up command prompt release the ip with ipconfig /release and then renew it with ipconfig /renew.
Once every couple of days the wireless service seems to disappear. I've connected to the router from a wired computer and everything looks ok from the d-link panel, however its not showing up as an available wireless network on the wireless units. Pulling the power off for 30 seconds tends to get it working again. I'm configured bg and n. I need a mix... an old B laptop, have one machine that has a G NIC, and the rest are N.
After buying a new WNDR370. Sporadically and seemingly without any cause my internet will stop working. Diagnostic will always report it as "DNS Server is not responding." I've also discovered that if I enter my router settings and even just switch the DNS settings from Auto to manual or vice versa the problem corrects itself instantly-then next time it happens I just need to do it again.
I've already tried resetting my entire network and rebuilding the recommended way. Modem, Router, then computers-connecting each only after the prior has finished initializing. Hasn't worked though.
Currently I have my main rig connected directly to the modem to try and find out if I experience the problem at all this way, this is a pain in the ass though, and I don't know when long enough is long enough as the issue is completely random and simply just may not happen.
I have an EuroDOCSIS 3.0 cable modem from UPC Romania. It's a Cisco EPC3925, wireless modem.
My problem is that most of the time (like 80% of the time) when someone is starting or closing a PC that is connected using a wire, the whole internet crashes (wired PCs get a ! sign and the internet stops working and wireless PCs are getting disconnected completely from the network being unable to reconnect). This is solved by restarting the modem (unplugging/replugging it) or waiting for it to reconnect. I want to mention that during this process the modem lights show that everything is ok and nothing special happens.
First of all I called UPC technical support and the man there said that I should try to disable the firewall from the modem (which I had disabled already), if it won't work then to try to reset the modem to the factory settings (as I was thinking to do - because I configured the settings as I wished) and if this won't work then calling them back to change the modem.
I tried to reset to the factory settings and that didn't work at all after running tests over one week. After that I called UPC and they said that the modem is for sure the problem, they sent a technician (today) who also said that the modem is the problem. Ok ok, the technician replaced it and everything seemed to be good.
30 minutes ago my father started his PC and what should I see? Bam, internet crashing. 5 minutes ago i closed as well my PC and what should I see? The internet crashing again.
My Cisco 871w still stops working once a week.Today I found it frozen, after the weekend, and I have executed few commands from the HyperTerminal .The commands were given by cisco coleagues in previous post :show logshow ip int briefshow interfaces counters errorsshow interface FastEthernet1show interface FastEthernet1 statshow interface FastEthernet1 summaryshow interface FastEthernet1 switching
I have setup a Cisco SR520W and everything appears to be working. After a few hours, it looks like the WAN port stops forwarding traffic to the Internet gateway IP of the device.If I unplug and then plug in the network cable connecting the WAN port of the SR520W to my the modem, traffic startings flowing again. Also, if I restart the SR520W, the traffic will flow again.
I have a PIX 515e (8.0 (2)) and 1841 router (12.4(25)).I had the following setup working without issue:
[Internet] <-----> PIX <-----> 1841 <-----> [LAN]
I then tried to introduce VLANs and now I can not reach the Internet from the LAN. It seems that no nat translations are taking place.
-I can successfully ping the LAN from the PIX. -I can successfully ping the Internet from the PIX. -I can successfully ping the PIX inside_lan interface from the router -I can not ping the outside interface from the router -I can not ping the Internet from the router
I introduced the LAN side VLAN first and everything still worked. However, once i introduced the VLAN between the router and PIX, things have broken down. [code]
I have two Cisco ASA 5520's running software version 8.2(2) set up in a HA pair. The L2L vpn is set up and works as expected between this site and another. The issue is that every few months, one subnet of the VPN, the same one all the time, stops forwarding/receiving traffic. The device in the remote location is not a Cisco device but I am certain the issue lies with the ASA as when I fail over to the slave device the VPN works again, failing back again however stays with the subnet still not passing traffic. I need to reboot the device before it starts forwarding traffic on the subnet again.
I am at a loss on configuring a new ASA5505 for multiple static port translations.I would have expected to simply add several service command to a network object to complete the task, however, the service command overrides the previous and replaces rather than adds to the translations. [code] However, if entered in that order the 8443 overwrites the 8080 static translation.What is the correct procedure to establish multiple translations? If someone could also provide the "old" style for pre 8.2 release, I'd like to compare because I thought I used to do this with an access-list somewhere.
My computer runs bit torrent almost all the time, sometimes when I start Firefox the home page google never loads and neither do any other web pages yet bit torrent is still working as if nothing has changed. If I start a download in Firefox come back to the pc a few hours later Google doesn't load but the Firefox download still continues.What causes this is it DNS ?
My internet (wired and wireless) usually works fine, but occasionally (read: every few days to weeks) the connection will suddenly black out for a period of time, anywhere from an hour to a day. I have tried resetting both my router and modem, and going through all the settings on my laptop, but I'm pretty sure it's not my computer, as no other devices can connect either. During the blackouts, when I look at the modem, the internet light will turn on for a second, then go off and then the red "alarm" light (aka "something is wrong" light) starts blinking like crazy, and this keeps repeating. This resolves itself after anywhere from a few hours to a whole day and everything is normal again. The light show, and the fact that I can't find any other problems, leads me to believe that it could be a problem with my provider (or the network itself) and not a hardware or software problem, but I can't be sure of this.Also, during the blackouts, I can connect to the network, but it shows that limited connectivity symbol (exclamation mark thing) and says no internet.
I have a problem with a wireless adaptor on a Toshiba Tecra (A11-1EE - PTSE0E-065052EN) running Windows 7.The wireless adaptor works fine but every now and again it will just stop working. The operating system says that the adaptor is turned off but it isn't. I've checked the driver but it is up to date.I have to disable the driver and then enable it again and then the adaptor begins to work correctly again.

So here's my setup:Computer A is connected directly to a cable modem box via USB. Computer B (which is sometimes a laptop and sometimes a desktop) is connected to Computer A and shares its internet connection via Ethernet because I am too cheap to buy a router.A few days ago we borrowed a Belkin wireless router so we could have both desktops, the laptop, and my fiance's iPod Touch access the internet at the same time. That worked fine but once we returned the router and tried to put everything back to normal, it didn't work. The only computer able to access the internet is Computer A (or whichever one is directly connected).I tried resetting the modem and restarting both machines. I tried disabling all of the connections that showed up from using the router.Windows states that the IP isn't properly configured or something of that nature. I tried setting it to automatically set the IP but to no avail.Here is the part that really confuses me - I can access Computer B from Computer A via LAN using the ethernet cable, so the connection between the two computers is fine.
I have a Comcast Motorola Surfboard rental modem. It works fine, great speeds etc etc. It has no router or bridge support.
I use this modem to connect to the web on my ps3 and PC. What I have been doing is simply unplugging the ethernet cord from one device, and putting it in the other device to switch. But of course things can't be simple...
Every time I switch devices, the modem tries to reconnect and does a cycle where every time it only reaches the "Send" light. So I have to power cycle my modem and wait about a half hour before my connection resumes...
I read something about PPPoE, but Comcast doesn't even use it so that won't work.
Router randomly stops working and sometimes reconnects by it self and sometimes I have to manual reset the router. Also I only get 2-3 bars wireless. Is my router not configured properly or damaged?
I have a windows vista pc networked to a second pc. I have wirelessly networked internet to 2 laptops. I have an actiontec wireless modem by verizon. All of a sudden my host pc started randomly losing internet connection, but the wireless laptops still have a signal. It seems like the host sometimes can't "see" the modem.Here are my settings while the internet is functioning.Microsoft Windows [Version 6.0.6001]Copyright (c) 2006 Microsoft Corporation.

I have a TL-WR740N router, and the problem is that when I shut down my Desktop PC wherein the router is connected, the devices that are connected via Wi-fi can't connect to the internet anymore even though the router is still ON.
I bought this router and ever since my internet connection will drop out for 5 minutes at a time then come back in. This happens on both wifi and the wired connection. The weird part about it is that if there is a program that maintains a constant connection, e.g. xbox live or an online MMO, they don't lose connection when every other device or even tabs within the same browser all lose connection.
My D-Link DIR-655 will no longer let me pull up any web pages after several hours. For example, it works great when first rebooted, but the next morning web pages have timed out. When it is broken, I'm unable to connect to web pages via another wireless access point that i've plugged into the D-Link. I'm unable to use any of the wireless PCs or devices in my house.After it's rebooted, it works well for at least a few hours. It has the latest firmware and has basic, out of the box settings.
There were 6 computers on the 2.4GHz band, and 2 on the 5GHz.Everytime the people on the 2.4GHz band would get disconnected for no reason, but this router should be able to handle that number easily. After lots of fiddling, like telling people to shut down their phones WiFi, I finally found the culprit:
N and G mixed mode
Even with only Wireless-N devices there would be problems. N-only mode worked well.That is unpractical for me as there are some devices here that are still on Wireless-G, like game consoles and some phones.
