I'm trying to do vpn between two routers. The first router model 1841. Dial settings is like this:
crypto isakmp policy 1
encr aes

My other is model c850
crypto isakmp key 6 cisco address 82.80.137.216

Ive just bought a new toshiba notebook c850 andf i want to connect to the internet using a wireless usb modem. Ive used 2 seperate modems and none of them work it keeps saying to reinstall or update the device. I dont have wifi and these modems work on all of my other computers why not this one?
View 1 Replies View RelatedI checked what she needed, updated her drivers for Ethernet and Wireless, and the Device Manager is stating that they are both working fine. (no ! or ? on them)When I plug in an ethernet cable it works fine. It gets connection pretty well through my BT Infinity modem.However the wireless will not pick up any connections at all. I attempted troubleshooting, and all it says, "Your network adapter is experiencing problems" etc.I thought that I may need to turn on Wireless Association on the modem, but that didn't work. My dads laptop is also a Windows 7 Laptop and that works fine and will bring up all connections in the area, including mine.
So I googled around, and I found that I may need to turn on a wireless switch. After looking around the laptop, I noticed two things. 1) There is no wireless switch, and 2) There is an orange light above the WIFI symbol.So I googled around a bit more, and found it might be turned off in the FN+f8 Flash card feature. At first I couldn't actually bring this up, so I reinstalled the flash card, and it began to work. It claims the wireless connection is "On".I am not sure what to do next. I have checked the services to make sure WLAN Autoconfig is on Automatic, and Started, and it is. I also tried disabling, then enabling both ethernet, and wireless connections, which did nothing.
My laptop is running on windows 7 ultimate, model is Toshiba satellite c850-F10M. and am lacking network drivers especially LAN/WAN.

They both have HWIC-2T modules, but it's almost impossible for me to have the CAB-SS-2626X Smart Serial crossover cable on time. So, I was wondering if there will be some kind of a problem if I connect them through a UTP crossover cable using their FastEthernet interfaces. I suppose it will not "simulate" a serial wan connection but, would it work as a router to router connection?

The Metro E will be primary, and if the BGP peer goes down, I want it to switchover to the 1841. Can it be done and is there an example of the BGP setup to work off of?
View 1 Replies View RelatedThis is only a small portion of our network but my question is, can these 1841 routers handle a 45Meg connection? I thought these routers were designed for T1/E1 type speeds. I know I saw a router performance document somewhere that showed 1841's could handle 38.4MB of traffic and that is only with routing turned on. If anything else is enabled, like access lists, NetFlow or whatever, that number will decrease because of the capacity of the router. Am I correct in these statements? Any document or anything else that shows performance of these routers?
View 14 Replies View RelatedI have two 1841's, setting up a Lab WAN in Packet Tracer. I have one of the 1841's run to a DSL modem, then out to the cloud and the same setup on the other end... from the cloud to the DSL modem and to the 1841 on that end... I have all green lights, so that tells me layer 2 is up, but I'm trying to figure out
what IP to assign the routers to test pinging and getting traffic flowing. but the DSL Modem's have the public IP's and dynamically assign an IP to the routers? I've also tried setting up a static IP on the routers fa0/0 interfaces and the pings fail.. Wondering what I am missing to get these two talking.
While I managed to connect to each router individually, I decided it was time to connect the routers together via serial; as I don't have any serial cables and need to buy some, what serial cables I need, as well as to ask whether I have the right cards in my router(s) that will allow me to do so.
I bought 3 1841 routers, and all have a 1 port serial WAN Interface Card (WIC 1-T); one router has 2 of these, and one router has a WIC-1B-S/T .. My question is, can I connect the routers with a serial cable via WIC 1-T, or do I need a 2-T
I have 1841, 2800 and 3800 routers and need to do IOS upgrade to all of them. Existing routers do not have enough flash to hold 2 IOS images.if the router has 12.4.13r ROM IOS, will I be able to boot the ISR router via Cisco brand USB? That means in case something goes wrong while I am uploading new IOS to the router via WAN and something wrong, now router in ROMMON mode. If a local site person has a Cisco USB with an IOS in it, can he just stick it to the router and reboot the router and router will go out of rommon and go into normal mode? After it is working, then I can put the running IOS onto the exisitng CF card so now I can remove the USB and the CF card has a good IOS and reboot the router again.I am just trying to find a safe way to upgrade the site when they don't have big enough flash to hold 2 IOS at the same time. The local person is not technical so asking him to setup tftp server and put the IOS in the computer and so I can do tftpdnld while in rommon mode to grab the IOS from his tftp will be difficult to have the local person to set it up.
If ISR can boot off of the IOS in USB only, then I assume the requiremetn is the ROM IOS needs to be 12.4.13r. Then what is a safe way to upgrade the ROM IOS to this then? I never upgrade ROM IOS before so don't know what kind of problem I may run into and whether it's higher risk to upgrade this than upgrading the regular ios? If it is, then all my routers won't have this ROM IOS version, so that means I can't use USB to boot then? Will that means I am down to tftp server option? ( I heard xmodem won't work as it will time out before the ios can load via the slow dialup link into the router to rescue it from rommon mode).
I would like to set up a POTS Dial connection between 2 Cisco routers, using the modem card WIC-1AM-V2. I'd like to use this as an out-of-band connection to a remote site, if the primary internet connection fails. So, this setup will only be used in one direction, 1 router placing calls, the other one receiving calls.Here's my config of the receiving router:
chat-script dial "" ATZ AT OK "ATX3D T" ATS0=8 TIMEOUT 120 CONNECT C
interface Async0/2/0 description out of band for network no ip address encapsulation slip async mode interactive
line 0/2/0 session-timeout 5 absolute-timeout 10 script connection dial login local modem InOut transport input all escape-character BREAK autoselect ppp stopbits 1 speed 115200 flowcontrol hardware
[code]....
This config is working fine, when dialing in via a Windows Hyperterminal Dial connection. After a while of dialing I get the login prompt of the router.Now I want to have a router placing calls instead of a Windows Server. I can't figure out how to tell a router to place calls to a POTS phone number.

I am putting an pre-labbed DMVPN Hub config onto a production 1841. We had to upgrade the IOS to support protection with NAT so the current IOS we're running is c1841-adventerprisek9-mz.124-25g.bin.I can paste the configuration in fine (via the tunnel interfaces) and the router accepts it however the 'show dmvpn', 'debug dmvpn' and other related commands don't work. I have checked the IOS feature navigator and it definitely shows that DMVPN phase 1 and 2 are supported in this image.

View 1 Replies View RelatedWe have a 1841 setup with WAN and LAN subinterfaced(2 WAN connections, 1 internal VLANs) and I am recieving some pretty horrible throughput when traversing the router to the WAN.
I am receiving about 2 MBPS down but around 5 up.Currently there is a ACL on the WAN interface, and as well we are running NAT NVI. It is possible that this might have something to do with it, but I am not sure.
Most of the CPU is going to IP input however I cannot seem to determine the cause. One thing I am thinking is the overload for NVI is using a route-map. Could that cause it to process switch instead of fast/CEF switch?
i have 6 sites using tandberg visioconference system, each site have a cisco router 1841 configured with ipsec vpn, i have a 4 conference a week and my bandwidth is 2 meg, and when people are working we have a lot of problems and cut in our visio conference.
I have a big problem, i want to make a high level QOS priority to my TANDBERG visio conference system between my sites, the issues is that there is an IPSEC VPN in my cisco routers between those sites and as i know if the traffic is crypted we can not separate the packets or give higher priority to packets over anothers.
can i mark traffic in the lan interface and and make a high priority befors the packets go through the ipsec tunnel?

View 1 Replies View RelatedOK ran into a little problem with getting this to work. Only group members participate in the encryption process, correct?
I have numerous remotes all coming into one central location. I set up a KS and have currently only 2 of the remote routers set up as GM's, with the intention of the others coming into play as I move forward. Here is basically what I have in my KS and GM's:
KS

GM's
crypto isakmp policy 10 encr aes authentication pre-share group 2 lifetime [code]....
So I applied the crypto map to the serial interfaces on my routers on either side of the cloud (central-ASR1002 and remote-ISR1841). When I did this, ALL the remotes went down and I'm not sure why. Even the ones that didn't have anything to do with gdoi. Ya, it wasn't good. I thought that only the group members would be affected.
Is it the fact that my acl is encrypting any to any? Surely I don't have to reverse that and have two statements with the same syntax. I'm basically just trying to encrypt all traffic from specific remotes back to the central side. However, I'm trying to do it without taking down the rest of my network .
I have recently started a new job where the IOS on the 1841 routers is version 12.4. These are from 2006 mainly, probably when the routers were bought.should I upgrade to 15.0? Mainly just to plug security holes that cisco have found?

ezvpn client works fine for normal users that want to just authenticate with the Cisco vpn client. i have a site 2 site setup from the pix to my house, the connection is "up" on both ends, i see phase2 initiate under the pix logs . try to ping nothing happens, even drop down the byte size and the DF bit (aka ping xxx.xxx.xxx.xxx -l 100 -f ) ping to the next routed interface hop and i get "no translation group found for icmp src outside: xxx.xxx.xxx.xxx <--- my internal network dst inside xxx.xxx.xxx.xxx <---- pix internal network .

Here is my current situation, I have 3 Internet connections as below, at the moment they are terminate into the ASA.
ADSL Modem 1 (routed mode) ADSL Modem 2 (routed mode) Mid band Ethernet Tail (10m/10m)
ASA 5510 LAN Switch
I want to change it to the following, in order to use PBR on the router. ADSL Modem 1 (/29 Ip block) ADSL Modem 2 (/29 ip block) Mid band Ethernet Tail (10m/10m) (/28 block)
Router ASA 5510 LAN Switch
I need your opinion on the following points
1. What is the best suited router considering i have 2 adsl connections and i will need 3 WAN + 1 LAN ports in total.
2. Where should I run the NAT ? on ASA or the router. (I do have around 20 L2L IPSEC VPN tunnel on the ASA). In the new setup I would like to use ADSL 1 for the internet browsing and use ADSL 2 and Ethernet Tail for incoming service (+some outgoing to specific destinations or based on specific services)
3. I have an old 1841 with 2 Ethernet ports, am i better off buying 2 x ADSL2+ cards and use them with expansion slots?
4. Both adsl connections are PPPOA based, Can I put both adsl modems into bridge mode and create pppoa connections on 1841? (I will still have to buy a HWIC 2 ports Ethernet card).
5. Should i go for any of the above options or am i better of buying a new router?
