Cisco WAN :: 1921 - Static NAT Hangs Every Few Days
Apr 10, 2011
I am running a 1921 with 15.0(1)M4 on it. The router has a /29 public block assigned to it so I have a public IP for my router's GW, a public IP for the WAN interface on the router, a public IP for PAT and the three remaining public IPs I use them as static NATs for internal hosts.
My problem is that the particular static NAT assigned to static host1 seems to "hang" every few days. You can ping the public IP and it will respond but the rest of the services of the host like www, ftp and telnet do not respond. If I reboot the router then all services of host1 will work again. Note that all other static IPs including the ones used for static host2, host3 and PAT will always work and never give any problems.
I am fairly certain that this is not a config problem so I have shuffled around the public-to-private NAT entries. Basically whatever public IP I assign to this host1 will at some point hang. The host2, host3 and PAT always work and never hang no matter what public IP I issue to them.
So since it isn't a problem with the public IP I changed the private IP of host1 and still it hung!! This host1 happens to be a linux box. host2 and host3 are a Windows server and a different flavor linux if that make some kind of difference.

I have a couple a questions answers on which i cant google for a period. BTW maybe i simly use wrong aproach to choose keywords.
1) Is it possible to assign same ip address to the same client each time it authenticated, preferably without using DHCP? Im definely sure that it possible but cant find corresponded configuration examples (my device is Cisco 1921 with IOS 15.0.1).
2) Is it possible to assign dynamic crypto map to loopback interface (the purpose to make EASY VPN Server accessible through two interfaces - maybe you recommend other approach instead?) - as i move workingcrypto map from phy int to loopback - i cant connect with reason "Phace1 SA policy proposal not accepted"

We want to puchase new Cisco ISR 1921/K9 . i want to know does it support the following sample IP-SLA commands
ip sla 2icmp-echo 172.16.1.2timeout 500frequency 1ip sla schedule 2 life forever start-time now
track 10 rtr 1 reachability
delay down 1 up 1
!
track 20 rtr 2 reachability
delay down 1 up 1
ip route 0.0.0.0 0.0.0.0 192.168.1.2 track 10ip route 0.0.0.0 0.0.0.0 172.16.1.2 track 20
Im asking above question because we will need to enable ip-sla on the mentioned router. as i read on the cisco webside, it says Cisco-ISR-1921/K9-IP Base support only IP-SLA RESPONDER feature nothing else. If Cisco-921/K9 does not support the above commands , should i go for ordering Cisco-1921-SEC/K9 ?

Running ACS5.2, Windows XP Pro, Window Server 2003 and Cisco Anyconnect Client. When the machine name password changes between the PC and the AD server the ACS will error out with "24485 Machine authentication against Active Directory has failed because of wrong password".TAC has been working with us on this and sees the error in the logs but does not have an answer on with to do to solve this. It has the same problem with Wireless Zero. Once the PC is rebooted the error goes away for 30 days. We are in a hospital setting so this is a not just a minor problem

I'm having this weird problem with an IP phone behind a WGB. The setup is like this: Cisco controller -> Switch -> switch -> AP (Air LAP1142) -> WGB (Air LAP 1262) -> switch -> IP phone.
The phone works, sometimes. Sometime for days, sometime for hours, then it disconnects and what I have to do then to get it working again is to run this command on the bridge. "no workgroup-bridge unified-vlan-client", then wait for it to disassociate, then run "workgroup-bridge unified-vlan-client" and after that it gets a stable connection (for a undetermined amount of time).
Here´s the WGB config:
version 15.2
no service pad
service timestamps debug datetime msec

my PC and laptop are both suddenly running sluggish since yesterday morning. pages take forever to load; slow to start videos, etc. i called ATT this morning...the auto test said i needed to talk to someone because there was a problem noted. but the live rep ran tests and said the speeds were within the norm for my service. i asked her why the auto test reported an issue, and she checked, only to come back to say "it's a problem with the modem." oh, and a new one from them is $80-100+

We have 4 WAP121s running 1.0.1.10. After a couple of days of operation, they all become unusably slow. The admin web interface takes several minutes to load, and wireless clients timeout before RADIUS authentication can complete. Waiting long enough allows the diag info to be downloaded, which shows hostapd using all of the CPU time available: [code]
As a workaround, we used to use a small script to reboot them every night via SSH, but someone at Cisco made a less-than-brilliant decision to remove this advertised feature.

I have the problem that our ciscoworks server gets out of memory after few days. The memory utilization is always getting higher an higher (above 95%). Sometimes it is only after 3 days and sometimes it is after 1 week. So it happens not regularly. I have made an screenshot from the services which use a lot of memory. And at this time the memory utilization is getting higher and higher again....I think there is a problem with tomcat or dbsrv10.exe, there are also a lot of cwjava.exe running.

I have copied my computer's time in the router time setup under Time in the "tools" section of the router setup. After a few days of the router being up without a hard restart, it has lost 10 minutes somehow. I went to the logs and cleared them out and then looked at the entry showing that the log was cleared and looked at my computer clock and the time stamp of the log entry, and it was 10 minutes slower than my computer clock that I had originally set it from. I have a clock plugged in by the computer, and my computer always matches the clock that it plugged in, so I know it isn't my computer loosing time. What is going on here? Why does the router loose the correct time after it has been up and not unplugged or rebooted at all? I know that the router will loose the time if you unplug it, but this isn't the case here.

I'm experiencing some problems with a new X1000 gateway. The device works very well for 2-3 days. After that period, it seems to just freeze. I can connect to the wireless, but no IP address is leased. Wired clients keep their IP address, but can't connect to the internet. Communication between the wired clients is still possible (Ping, CIFS, LAN games,...). The DSL sync LED is lit as is the Internet LED. The management interface does not load. Doesn't matter is there has been a lot of internet traffic or virtually none. The only way to make it work again, is to cycle the power.
I've been fiddling with the different features from all off to all on, but the problem persists. I even got a replacement device, but that has the exact same problems. My ISP tells me that the Cisco and Linksys devices are fit to work on their network. I'm using a Zyxel gateway at the moment, which is absolutely fantastic, but has no wireless and useless QoS management.

I have the DIR-655 rev B1 with 2.03NA firmware. After 7 days the system time falls back an hour. The timezone settings are correct and I have used both 0.us.pool.ntp.org and DLink's time servers.

TL-WR1043ND disconnects every two days

Region : UnitedStates
Model : TL-WR1043ND
Hardware Version : V1
Firmware Version : 3.13.12 Build 121210 Rel.73912n (Beta)
ISP :
I have tried to go through the tech support email but no dice. My router disconnects every two days. The sys light will stay solid and require a reboot and my computer connected to the router will be unaffected . I have a 30mb connection with only 2-3 wireless clients on at the same time as the wired. The response I got from tech support email after waiting almost a week without a response was :
Because there's not much we can do to fix the problem right now and TL-WR1042ND is more competent for your network, I suggest you to change for it.
If you still don't wanna change for TL-WR1042ND, change for a new TL-WR1043ND to have a try."
This is answer I get after already asking once why they want me to downgrade for a different router . What exactly the TL-WR1042ND is going to do for me that the one I have won't,but I cannot get a answer.I have no idea what they mean by "competent ", I don't believe my network is anything special and see no reason why the problem would be fixed by downgrading . This is the second router since December I have had and really dont feel like paying another 15$ shipping back to newegg for a refund.

I have a wireless schedule setup on my DIR-655. Works great. Now I would like to run different hours on different days. Have wireless up on certain hours during the week, different hours on weekends.
How do I set up a schedule to one one set of hours during the week, and a different set of hours during the weekend?

My RV110W is only a few months old and apparently started ginvg me issues shortly after I got it. Since it was new, however, I only recently suspected it as the culprit!
I have a simple home/small business setup. A single PC wired into the lan and a handful of occasional use laptops & Android phones/tablets and a Playstation.My connection is a 30M down / 5M up cable link. I have a UBEE DOCSYS 3.0 cable modem operating in passthru mode to my RV110W.
Over the course of several days, thruput drops from the measured 30/5 down to as low as 1/whatever. Rebooting the RV110W restored full speed. The UBEE has never been rebooted during this time. Connecting my wired desktop PC directly to the UBEE modem give me the full 30 downlink speed even when the RV110W perfomance has dropped to 5 or even 1.
I am using onle a single wireless LAN, no logging turned on, no VPN, no other 'tuning of settings.As it is, this device must be rebooted every few days to restore full network speed. This is unacceptable, of course - especially from a small business class device!

My set up is a 2wire router that connects to the internet, with an ethernet power plug connected to it. Over the other side of the house, I have the other ethernet power plug connected, with a Netgear router in access point mode.The main router is on 192.168.1.1, and the access point is on 192.168.1.3. The DCHP server is enabled on the main router with range 192.168.64 to 192.168.1.253. The access point has the DCHP server turned off. The routers have the same APN and security (WPA2-PSK).Also, the wireless channels don't overlap, channel 1 and 11.Now to my problem:The internet always works fine for a few days when the routers are turned on. But at some point between 1 to 3 days later, every computer can't obtain an IP address while connected to the access point. But all computers can connect to the main router (i.e. when closer to the main router than the access point), and then go near the access point and it keeps the connection. If I reboot the access point, then everything works again for a few days.

Region : UnitedKingdom
Model : TL-WR1043ND
Hardware Version : v1
Firmware Version : TL-WR1043ND_V1_120405
ISP : BT Infinity (1)
I have a TL-WR1043ND v1 with the latest firmware installed TL-WR1043ND_V1_120405.I loose access to the router (can't see web page, can't config, can't restart).I have a Linux server on the Ethernet, and uplink through 200Mbps powerline adapter to the BT Infinity modem. A few other devices on the wireless.The router works well and I prefer it to the BT Home Hub 3 for fiber because it proved to be faster in many cases as tested.But after a few days the web interface becomes inaccessible. It's like the web server died or something. Browser says connection reset, if I try telnet to port 80 says connection refused.Actually I just did a full netcat scan (sudo netcat -z -v -192.168.1.1 1-65535) and all ports say connection refused.Ping works - I can ping it allright.DHCP server works too, just restarted a computer and got IP from the router.Port forwarding works as well and DynDNS seems to work as well as my ISP changes the IP periodically and I can always find the updated one.All works - exept I can't access the router in any way!If I restart (remove power and plug it back in), it boots and I can access the router again.So restarting won't work remotely, I actually have to go home to re-plug it!

A few weeks ago, I noticed that my Internet connection had slowed down to a crawl. I waited a few days hoping it would go away on its own, but it didn't get better. So I asked this question about how to make it faster.
The problem went away after I updated to the latest firmware, so I didn't follow up too carefully. But every few days since then, my Internet has slowed down again. Unlike before, all I have to do to fix it is open the router administration page and press the "Reboot" button. Nothing else seems to work, though I'm sure there are options I haven't tried.
If it makes a difference, my girlfriend and I both transfer large amounts of data fairly routinely for school (videoconferencing, downloading entire recorded lectures).
The router is a Cisco/Linksys WRT160N v3 that's about a year old. Most of the time, it deals with just two standard Windows 7 laptops.
What could be causing these slowdowns, and how can I get rid of them?
I installed dd-wrt on my router, and I seem to be getting higher and more consistent speeds. Perhaps more importantly, my memory use is fairly constant.

I am working on a request to clean up alot of excess cabling in one of our IDF's. I noticed that many of the connections have no lights on them and probably haven't been used in a long while. I would like to know if there is a CLI command I can run on the Cisco 3750 switch will allow me to bring up a list of ports which have not seen any activity for a period of time - for example, 30, 60, or 90 days.

Any issues on Cisco ISR / ISR G2 routers running 15.x code while doing NAT for large quantities of users (3000+) involving lock ups? This seems to be an ongoing issue for a customer. The symtom is present on 2811, 2911 and a 3945. The 3945 never spikes over 10% processor or memory utilization, yet still has these issues. The routers have been tested running 15.0(1)M5, 15.0(1)M7 and 15.1(4)M4 which all showed simular results. Other router side services are running such as NetFlow v9 to two destinations. Another interesting symtom, doing a "show ip nat translations" command will crash the router if executed at its peak usage period. NAT is to a single IP (sourced from outside interface), not a pool.

Few months back I had purchased this Router. But I did not use it till last week. Since the time I have installed it, it does freeze often (between 5 to 30 hours).
I can connect to devices within the subnet, but not elswhere. I have to remove the power and plug it back for it to respond. I have updated the firmware to the latest one that was on the Cisco site.

As i'm facing the issue with Cisco CSC module installed on ASA 5510, It hangs up and doesnt work sometime, so it is bypassing all the traffic without inspection through CSC module. After restarting ASA 5510 box, it works fine as it used to work. Now, My question is how can i refresh the module again without interrupting the ASA box/ and how can i avoid this problem forever? Because i cant interrupt the daily work due to this module problem by restarting the box again and again.
