1841 router IOS problem

I need help getting the IOS on a compact flash that somehow got erased so now I have to use the second 1841 in my lab to boot up the IOS on the first one. I also have IOS 15.4 that I want to put on both routers. I know I am supposed to be able to tftp the IOS from my laptop to the compact flash of the routers but I need help setting it all up correctly. I have several tftp servers I downloaded free including pumpkin and jounin tftp servers. I just need some direction. I have tried looking for articles and docs to read in order to configure both the routers and the tftp server with the proper configuration in order to transfer the new IOS file from my laptop to my router.
Any help would be greatly appreciated.
Thanks,
Jamie

And if I remember right, only CF-cards up to 1GB will work.
All my 2800 routers are loaded with 2 Gb CF.
There have been some people who were able to successfully use 4 Gb and 8 Gb CF just fine.
Alternatively, you can use the USB ports to boot the IOS. Of course, you have to make sure the bootstrap of your router has been upgraded to the latest bootstrap code/version.

NAC feature included in 1841 router with security IOS

I'm looking for some guidance, documentation regarding the capabilitys and configuration of NAC on an 1841 router. It looks like it's a software version of NAC that ties to a policy server, maybe an ACS server, or IAS server for example. Is that all it does, in other words, is the capability found mostly on the backend policy server and not the router itself? In that case, what is the router doing, I mean how does it work in relation to NAC? Is it only capable of blocking traffic at layer 3 rather than layer 2 as does 802.1x authentication on a switch of the Clean Access appliance offerred by Cisco?
thank you very much,
Bill

For NAC, the role of a device depends on your network security policy. You can have security applied to any device(s) or you can have it on a policy server which can ensure the security policy. Following link may help you

DlSW/SDLC 1841 ROUTER.

I have just tried to implement by first 1841 router.
I used the same template that I have for over 400 sites ( 1600 , 1700 , 2500 and 3600 series routers )
I get the dlsw peers established no problem.
The problem is on the serial interface in the router.
It is an IBM 5494 controller .
Here is the configuration that I have for the serial interface.
I have added the routers configuration.
Any ideas??? Is there something that I need to add to the serial interface on the 1841's that was not required before ???
My IOS is (C1841-ENTBASE-M), Version 12.3(11)T2

Can the 1841 router boot from system image from usbdisk?

I have a cisco1841 router with 32M CF card installed.
Now , i want boot a system image larger 32M from usbdisk.
First i insert the 128M usb flash disk to the 1841 router and format it, then i can see the device from dir command.
Second copy the larger ios image from tftp to the usb disk and successed,i can see the image with " dir usbflash0:" command.
Third i use this command "boot system " ,but there is no selection of "usbflash0: "
Does someone tell me that can the cisco 1841 router boot the system image from usb disk when reboot the router.
by the way the System Bootstrap, Version 12.4(13r)T

I have test that ， the 1841 router can boot from usb disk。
but there is a problem that when the router reload.
before the second " program load complete.........................."
there is about 3 minutes to wait.
So , the router boot from usb disk take long time than from CF card.
when use usb disk ,the hole progress of reloading the router will take about 300S.
It's too long .
Does something wrong?

Help needed with AT&T 3G MicroCell going through 1841 Router

I am trying to get an AT&T 3G MicroCell (made by Cisco) to communicate to the Internet through our Cisco 1841 Router.
The router has only basic NAT and no Firewall setting.
The AT&T 3G MicroCell is not a configurable device and it directly connected to a switch port on the router.
DHCP is supplied to it by the router.
We are using Comcast Business Class modem but it is set as a passive gateway pass through device so by passing the router is not an option.
The MicroCell is unable to establish connectivity with the AT&T auto-configuration on the Internet.
So far AT&T support has not been very helpful or knowledgeable.
Anyone have experience with the MicroCell device and connectivity?
They recommend some advanced settings for UPD and TCP ports but the router shows them as open.
It primarily uses ipsec ports
Any ideas?

I have this same issue with the MicroCell plugged directly into the WAN (DHCP) connection to the house from the ISP...................
I also have this same issue with the unit plugged into the DMZ on the router with pass all, all protocol's in and out .....
My problem is GPS related, as in the new 911 database has "virtually" moved my 2 bedroom house 4 miles east of my "physical" location.
Ain't modern tech great......(now if we could just get people great) only problem with high tech is............GARBAGE IN >> GARBAGE OUT........it still depends on "intelligent" life to program everything.

Need help regarding Cisco 1841 Router

hello everyone , i am need of help regarding configuring of FE 0/1 port. our company have a cisco 1841 router. The serial 0/0/0 is connected with VSAT for internet. The FE 0/0 is connected to switch(LAN) through which net connectivity is provided to all users. Recently a new VSAT has been installed at our site,with different IP series. So every time we want to switch between the two net connectivity we need to change the entire IP configuration of all users, which in turn prohibits the users from accessing the printers,data servers etc which are been set to our existing IP series. So, my idea was to configure the FE 0/1, so that just by changing the DNS will help us providing internet along with all other devices without changing the entire IP series. The new VSAT modem has a lan cable which can be connected to FE 0/1. Can any one help out in solving the problem. Our existing IP series is 192.168.3.1..... and the new VSAT series is 10.205.74.1......

Bao
Do I understand correctly that you will have 20 remote users who will telnet to the 2511 and from the 2511 will use reverse telnet to access the console of router1, router2, router3, etc which have their console ports connected to async ports of the 2511? If that understanding is correct then the firewall only needs to open TCP port 23 for telnet. The other ports (2001, 2002, etc) are between the 2511 and router1, router2, etc and will not be seen by the firewall. If my understanding is not correct then please clarify.
I do not believe that you will find an image for the 2500 that supports SSH.

1841 - 3G HWIC problem

Using Cisco 1841 router with HWIC 3G Module, Now I can ping any public IP address from the router, but cant browse the internet from PC.. through Ethernet or Dor11-WiFi.
How can I get DNS address automatically, or how can can I check if its already assigned to the router!! It looks like I have only IP address in the router.... Please look at attached configuration file and update if you have any idea.

Are you using your ISP DNS server or just any public DNS server? If you didn't use your ISP DNS server, try to use them. Using your own ISP DNS server should provide you with faster DNS response rather than just any public DNS server.
To find out your ISP DNS server (and other stuff), you can issue the following command on your router
show dhcp server
Make sure you are using the correct version of Cisco IOSÂ® Software. The 3G WWAN HWIC is supported on Cisco IOS Software Release 12.4(15)T and later.

WCCP on 1841 router

Having a problem with a configuration of our guest network and our content filter (S170 IronPort). The 1841 has 3 interfaces. 0/0 is on the LAN side, 0/1/0 is connected to the Ironport, 0/1 is connected to the ISP. So we would like to redirect all traffic from the LAn interface to the Ironport and then out to the internet. For some reason with the configuration below it does not redirect the traffic. When I apply WCCP to the LAN interface it redirects but the cleints stop gettin g internet traffic. Does anyone have any expereince or ideas on how to make this work in the environment?

Connection issue between Cisco 515 Pix and Cisco 1841 router

Hi,
I am having a problem getting a Cisco Pix 515 communicating to a Cisco 1841. I am currently studying for CCNA so forgive me if it's obvious to the rest of you where the problem lies.
The client currently has an ISDN service which is being moved over to a 2MB E1 connection.
I have configured the 1841 router with G.703 WIC according to the information given to me by the ISP. I have configured the 1841 to have the same internal IP as the ISDN Cisco 800 series router, hoping for a simple swap over. The Pix 515 sits behind the ISDN at present and will be behind the 1841 when it is active.
Once I unplug the 800 series ISDN router and plug the 1841 into the pix, I cannot get any response what so ever. I have tried changing the ethernet connection speeds between the pix and 1841 hoping it would be as simple as that without success. Can't get ping responses from either end but I can when the ISDN service is plugged in. Both ISDN and E1 link are supplied by the same ISP, Telstra Australia and the fixed IP's are able to move over to the E1 service.
I have not touched the pix in any way. A seperate company configured the router a couple of years ago.
I have included the configurations of the existing ISDN, Pix and the 1841 for you to review. Any advise/solutions would be greatly appreciated.
Thanks in Advance,

Hi,
The outside interface on your PIX is configured as 10BaseT which would be fine when using the original 800 series ISDN router.
Now with your new 1841, the interface that the PIX connects to is Fast Ethernet so you need to change your outside interface on the PIX to the same
If you want to use auto negotiation between the PIX and router then the command to do this on the PIX is
interface ethernet0 auto
I recommend using hard coded settings between the PIX and router and the command to do this on this PIX is
interface ethernet0 100full
You will also need to change your router as:
interface FastEthernet0/0
speed 100
duplex full
If you can't configure the PIX as you mentioned an external company did it, then i guess you could change your Fast Ethernet interface to "speed 10", "duplex half".
This won't create a bottleneck as you only have a 2 MB connection to your ISP
Everything else looks good, don't worry about asking questions on the forum, this is what its for.

Some of my songs in iPad Mini with RD disappeared all the sudden and I need to redownload it again. Same thing happen to my iPod touch 5 too. What's wrong with it? Is it the iOS problem?

Some of my songs in iPad Mini with RD disappeared all the sudden and I need to redownload it again. Same thing happen to my iPod touch 5 too. What's wrong with it? Is it the iOS problem?

Delete the music in your iTunes library, then go to iTunes store, Quick Link, 'Purchased' to redownload again.

My MacBook Pro will not connect to my home wifi but will connect everywhere else. My other Apple devices (I-pad, I-touch, another MacBook Pro) connect to the router without problems. It was working fine but all of a sudden stopped working.Thanks!

My MacBook Pro will not connect to my home wifi but will connect everywhere else. My other Apple devices (I-pad, I-touch, another MacBook Pro) connect to the router without problems. It was working fine but all of a sudden stopped working.Thanks!

try this.
get back into your router's settings and start deleting devices that are not connected to your router.
you can also delete the ones that are connected - they'll connect again.
on the DHCP side of it, increase the amount of users that can connect/log in to your router.
see if that sorts it out for you.
good luck.

I can't open my iPod Touch - tried the restore message and then error mewssage 3014 - iOS problems???

I can't open my iPod Touch - tried the restore message and then error mewssage 3014 - iOS problems???

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.
