I have a server that I lease that is hosted at a datacenter. Our company is going to lease a half rack and put our own equipment in it as well as a disaster recovery site. The problem is that the one server I mentioned has SQL on it and we have applications that were devloped in house ages ago that hit that SQL instance. Those applications are hard coded to the IP address of that server. We could just change it in the code, but the source code for one of the applications have disappeared over time. Now that you know my situation, my question is this. Can I make a NAT rule or something that says when traffic is destined for xxx.xxx.xxx.123, to re-routes it to xxx.xxx.xxx.321? Currently our endpoint device here is a Cisco UC520. The other end we have no control over.
View 2 Replies View RelatedI am trying to setup time service on two devices. Once is a UC520, the second an 1840 router. I would like to use the FQDN of the time server which is north-america.pool.ntp.org. This is the recommended procedure as per ntp.org due to changes of IP addresses of time servers.
On the UC520 this is not a problem. I type in "ntp server north-america.pool.ntp.org" and this is how the command stays in the config. On the 1800 the FQDN is resolved and inserted into the config as an IP address. This works for now but kinda defeats the purpose of using a FQDN.
How can I keep the 1800 from converting to IP?

View 7 Replies View RelatedLet me start with some infrastructure details ...
Cisco C2901 as our Main Router
Cisco UC520 as Communication Platform
Cisco C3560x as Core-Switch
VLAN 10 : Data
VLAN 100 : VOICE
Everything is working but i m not sure if the switchport config is right in that way.
As an example :
interface GigabitEthernet 0/6
switchport access vlan 10
switchport mode access
switchport voice vlan 100
spanning-tree portfast
When we connect an Cisco 7971g and an pc everything is working fine. But when i start wireshark on the pc behind the phone you see a lot of UDP Traffic source UC520 destination 239.10.16.8 or 239.10.16.16. At this point i m getting confused. So i start looking for the cisco phone config, VLAN ID on the phone is 100 (i think that is ok) but the PC-VLAN part is empty?
The main thing is, how can i stop this cisco-sccp traffic on the pc port (prtg shows me a average of 200 kbit/s) i think it is an config fault.
I have a sge2000p to install with a uc520. I have all data traffic passing ok but voice will not work. Phones to not get ip etc.

View 1 Replies View RelatedSo for the longest time now my internet just goes in and out constantly.When I moved out of my parents house and got my own internet hooked up it all started. Internet would go in and out a lot both on wireless and when I was hooked up to local connection. I had Charter and told them and they gave me a new modem but problem stayed so I just assumed it was the wireless router I had bought. I moved to another city and am still using the same wireless router and got another modem from Charter in my new house. Problem is still there and is way worse.About every 5 mins I lose connection for about 30 secs. It always says connected though but pages won't load and says connection issues but like I said my wireless connection always shows excellent connection. About once a week it will go out and not come back unless I unplug the modem and router and plug it all back in.
View 4 Replies View RelatedMy internet connection has been dropping constantly since the beginning of this year. I cut out for ~10 seconds then regain connection. This gets annoying especially when I'm gaming (Left 4 Dead 2, Counter-Strike, etc.). The modem lights stay on as well as my router lights. I have already called in three of my ISP's (Time Warner Cable) technicians all of whom think they have fixed the problem but haven't. I have changed my modem, router, ethernet cords; one of the technicians also changed the head of the cable wire outside at the cable box. I have also tried connecting the modem directly to my PC, but the same problem still occurs. I don't believe it's a problem with my PC because it's relatively new (~1 year) and all the other computers in the house cuts out as well.
View 6 Replies View RelatedWhenever I am browsing the web, or listening to an internet radio, or even gaming, after about 30 minutes my internet will cut out. The weird thing though, is that it will come back when I close the game/browser. It seems that whatever tab or application I have running the longest nullifies my internet connection after awhile and will not turn back on until I close out of that specific application.
View 1 Replies View RelatedI am connected to the router with a cable , a router which my internet provider supplied me with.The problem used to happen before , occasionally , but the disconnecting has drastically increased lately , and these days it has become unbearable , it occurs at least once every hour , especially when i'm playing a game online or so.The disconnects last very shortly , or until i reset my router or disable/enable my network in network connections.I have 2 more laptops in the house , connected via wireless , and they've had no issues with this.The first time these problems occurred i was able to fix it just by doing the windows troubleshoot, which lead to an error saying "Default gateway is not available".I found a lot of threads on the internet regarding this issue , and tried all of them but none seemed to work.
I tried downloading newest drivers from my motherboard site first , then from Realtek's site, then deleting old drivers via DriverSweeper aswell , just in case , but it did nothing.I tried changing the Speed & Duplex to 100mbp/s Full Duplex , which has solved the issue for some , but again it did nothing.I called my internet provider , was told to use static IP address and type it in manually and if it didn't work to try plugging the cable into another slot on the router ,And after all those things , i feel like the problems is even bigger now. I now no longer get the "Default gateway is not available" error , and the only solution is to reset router or disable/enable network , which leads to the network being "unidentified" for some time before it connects.
my wifes laptop to working better for internet connectivity.Now my mother's is having similiar issues, constantly losing connection and what notI did a couple of scans using the programs that were recommended on that previous threadHere are the logs.
View 3 Replies View RelatedI have a SF 200-24P Cisco switch that seems to be rebooting constantly, When i connect it to mains power it seems to go through a startup cycle, in this order - i have tried this with no network devices attached and the same thing happens
1. Fan starts - continously runs
2. Very quick flash of all RJ45 ports.
3. After about 30 seconds, any network devices connected have an acticity light
4. After about another 45 seconds, all ports light up including the activity and POE orange LEDs for about 5- 10 seconds then go off.
5. About 10 seconds later the ports all light up again and stay on for about 5 seconds.
6. All ports go off and the cycle keeps repeating continously.
I have tried pinging the switch without success.I have also tried disconnecting all devices from each port with no success.At no time does the system LED on the left light up.I have tried resetting to factory default with reset pot on the left side.This is a brand new shipped switch from our cisco supplier, could it be DOA?
We have a working L2 OOB VG deployment. The NAC agent pops up then says it has granted full access. The issue is about 45 seconds later it pops again then says it has granted full netowrk access. Then it does it again...etc.... The CAM thinks things are fine as it just keeps adding the user to the OUL.

Even when connected via an Ethernet cable the problem persists.I have kinda contained the problem to his laptop or the router they are using because the other laptop they have never disconnects and works perfectly fiine.
View 2 Replies View RelatedI will be moving away from my home computer but will still want access to it so I am trying to set up a VPN between it (home computer is windows 7) and my fedora 15 machine. They are currently on the same 192.168.1.0/24 network so I'm wondering if that may be the cause for my troubles.
Here's my setup:
Fedora 15 (192.168.1.3) is running the PPTP server with pptpd and gives 192.168.1.66 to any vpn client that connects to it./etc/pptpd.conf only has "localip 192.168.1.3" and "remoteip 192.168.1.66" options in it /etc/ppp/options.pptpd has "refuse-pap, refuse-chap, refuse-mschap, require-mschap-v2, require-mppe-128, proxyarp, lock, nobsdcomp, novj, novjccomp, nologfd, debug, dump" options Windows 7 (192.168.1.6, 192.168.1.66) is the client and I have it set to use connect to the public IP address of my router, PPTP, require encryption, only allow mschap-v2, don't use gateway in ipv4 properties.Both machines are connected to the same Belkin router (192.168.1.254) and I can ping locally to and from each computer no problem. The problem is my VPN connection is very inconsistent. I will open a ftp connection to 192.168.1.66 from 192.168.1.3, login, start uploading a file, get about 10MB uploaded, and then the VPN connection will die and the upload will fail. But, when I have "ping 192.168.1.66" running while uploading, the connection stays alive.
My Internet will disconnect & then reconnect constantly. I have 2 laptops & they are both on my home network & I have no trouble with the other one so I assume there is nothing wrong with both the Internet service & router. The laptop with the problem is an acer/aspire 5720z. The Wireless Network Adapter is a Atheros AR5007EG. When I go to the Adapter Properties the status reads "The device is working properly". When I go to Control Panel>Network & Sharing Center my Wireless Network Connection Signal Strength reads Excellent. The operating system is Windows Vista Home Premium.

I payed �50 for a new wireless card to try and fix the problem and it was fine for a few weeks now it is the same. Restarting the router makes no difference and this is happening all constantly over the last week without fail, i have tried updating my wireless drivers and using different wireless cards.

View 14 Replies View RelatedIt's been doing this for over 7 or 8 hours now. And no, there's no network connection, that's what the problem is here. This is a Windows XP desktop.Basically what it's doing is within a second, this icon disappears from the taskbar, then reappears, over and over again: When I hover over it, it gives me a message about not being connected. I can't get the exact message screencapped and I can hardly even read it, it disappears too quickly.Sometimes it gives me this instead, and the connection works, but only for as long as this icon is there:But it disappears too quickly for me to load any pages completely, so they always end up being incomplete pages. When I hover over this one, it says acquiring network address.When I click repair, it gets stuck on "renewing IP address" every time, without fail.
Previously the internet connection would drop occasionally, but restarting the computer has always brought it back. I have tried this countless times by now, I have tried clicking repair, I have tried resetting the router, I have tried manually removing the connection then reconnecting to it, I have tried command prompt and running through the ipconfig flushdns, release, and renew commands, I have tried logging on as a different user account, I have tried uninstalling my wireless adapter software then reinstalling it, I have tried using a different adapter [I get a different error with that one], I have ran a scan with Malwarebytes' Anti-Malware then retried all these things, but that didn't fix it either. If my brother wasn't asleep I'd be wiping the hard drive by now as a last resort. And I will be doing this first thing in the morning if it isn't fixed.
There is one other computer on the wireless network, and its connection never drops. Ever. It's a Windows 7 laptop. There are two other computers in the house, but they both connect using the ethernet cable, and those never drop, either. The two Wiis, the Xbox 360, and the 3DS also connect wirelessly, and one of the Wiis drops occasionally as well -- and it's not connecting right now, either.There is one more PC in the house, which also runs Windows XP, but I haven't gotten it to connect in weeks and I've pretty much given up on it. It'd be nice to get that to run, too, since I have to share this computer, but it's 7 years old, it's just too old and is stuck on "acquiring network address" with either adapter, if I'm remembering right.
This is everything I know. This problem is still occurring, and it just occurred randomly today, while the computer wasn't even in use. I can connect to the internet with a wired connection, but stretching the wire across the house isn't something the homeowner wants me to do, so I can't keep it permanently, as much as I desperately want to.I looked around at a few other threads and there was some sort of Wifi program I can install? But it won't install. Or rather, the .net framework is what's not installing. So I guess I can't use that. Hope it makes finding the problem still possible though, this is the only computer I have left since my other one won't connect anymore either.
I am using an HP Pavilion dm4 laptop, and I have been having issues with the internet. The internet on my computer constantly is going down even though my network is not having any issues. It goes down every hour or so and I have to press the wireless button once to turn it off and once to turn it back on in order for my computer to regain internet access. This just began happening in the last few days.

All of these computers are upstairs as well.I know for a fact it isn't the computer, since when my computer was upstairs it would work fine, but with everything exactly the same it'll be horrible downstairs.Only things I have thought of might be interference... but have zero idea how to find what would be causing the interference if any exist.
View 3 Replies View RelatedFirst, I'm running Windows7 64 bit. So whenever I download a decently sized file; my download will start and get good speed for a few minutes, then it will drop off and stop and my connection to the internet will be lost for a short time while the connection resets. This happens if I'm using a program like Steam to download a game, torrenting something, sometimes on my Xbox 360 when it needs to update itself or a game, occasionally on a large app or album off of iTunes or patching an online game. However, I have no issue watching YouTube videos or playing an online game while also having TeamSpeak running in the backround to chat. I don't lose connection when browsing the internet at all and recently I was able to stream a live event without issue but I only tried that once (I don't have Netflix or anything similar).It usally isn't a big issue because my download will pick up where it left off most of the time but its a pain in the butt to have to add on an extra hour to a download sometimes for this.
View 4 Replies View RelatedI've been having this problem for several months now and I've tried most of the "solutions" on this forum and many others to no success. This casually varies from day to day and even over the course of a day, sometimes I can go a week at a time without any problem and then other times I'll spend an entire weekend not getting any luck. Essentially my wireless connection will randomly cut out with severely different periods of time inbetween, can happen every few hours or every 10 minutes and as said on different days. Most of the time I have to restart my PC or power cycle to get it to start to work again but also some times It'll automatically reconnect after 5-10 seconds or a few minutes.
As I'm sure you've heard a thousand times this is extremely frustrating when browsing the web or trying to download a large file and constantly being interrupted. My kids who live downstairs and have their own PC's in their room don't have this problem, one is using a wired connection and the other a wireless. As I've stated it only started a few months ago and I've had this PC for a year and a half and the router nor the PC have not changed position in the house or had any drastic changes to either of them.
