I want to try ping remote ip every 5 mins , if ping fails wait for 3 mins then trigger reload , and router come up again if ping fails reload again.
my problem in configuring a cisco 1841 as VPN server using SDM, everytime i press Lunch Easy VPN Wizard botton, there were no response at all. my IOS is:
Cisco IOS Software, 1841 Software (C1841-ADVIPSERVICESK9-M), Version 12.4(15)T15, RELEASE SOFTWARE (fc3)

System image file is "flash:c1841-advipservicesk9-mz.124-15.T15.bin
by the way I took this IOS to other router with the same model(CISCO1841).
I have configured a Cisco router. I am able to ping google from rotuer. I can ping my local IP from router and router local IP to my machine. But I can not access internet on machine. I can not ping google and any other IP out of network.
View 11 Replies View RelatedI have setup a remote access on our 1841 device, with split tunnel.
now i am able to connect via the vpn tunnel, and even ping and telnet into the cisco device, but when i try to ping any device past the 1841, the ping fails and no traffic is even been encrypted to go over the vpn traffic (looking at the vpn client statistics).
From the ciscos side, pings to the vpn client is failing, yet i see the vpn client in the routing table.
Here is my config:

I have issues with port forwarding. I did, but it didn't work. Then I tried different ip addresses. Now I don't know how to delete those configurations, because when I try to overwrite it says already exist. And still port forwarding is not working. I did: ip nat inside source static tcp (ip and port numbers)Our device is 1841, also we have firewall within this router. DHCP is in our 3750.

i have 2 routers both 1841's and am trying to get a simple static vpn up and running. Now One router is at our main location (ill call it router a) and the remote location (ill call it router b). Both have internet connectivity that works, can ping router a from b and b to a. Now on router b side when i run show crypto isakmp sa on router b i get the following:
SBOneonta#show crypto isakmp sa

i72.43.229.138 is the router and the other ip is i have no idea! its no where in the config, but that shows me this router is trying to do something. Now on router a when i run the same command i get this:
show crypto isakmp sa
dst src state conn-id slot status
a whole lot of nothing! now i have been working on this for a few days now and i cant understand why i cant get this simple vpn tunnel to work! I have debuging on both routers, router a shows nothing period for vpn traffic, router b shows a connection from the 66.194.51.66 which again i have no idea who or where this ip is and its not in the config any where.

A few days ago my internet suddenly stopped working. I plugged in the ethernet cord and everything worked fine. Checking the properties in the device manager showed the device was working properly, I also tried resetting it to make sure it was enabled but it did not work.
Upon troubleshooting, the "Windows Network Diagnostic" said the problems was that the Wireless adapter was not turned on. Using the switch on the front of the laptop as well as the function keys does nothing. Usually a graphic pops up showing if the WiFi is on or off, changinging transparent to show the WiFi is disabled. Now when I turn the switch on it always appears transparent, effectively going from off to off
So I know the computer reads both the function keys and the switch on the front but both methods never actually turns the adapter on. I just finished a system restore and nothing has changed
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.

Then I tried to telnet to it using teraterm but it would just open a console window and then close.

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
crypto isakmp policy 10 encr aes authentication pre-share group 2crypto isakmp key testkey address [code].........
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?

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?
I have a cisco 1841 router which isn't able to boot properly from its IOS. it always prompt me on ROMMN.
Here it is:

I have a little problem configuring NAT on router 1841, like this is the topology:
WAN (PUBLIC´S ADDRESS) fast0/0 fast0/0/0 PUBLIC´S ADDRESS INSIDE (192.168.1.0/24)
ROUTER ====== X.X.X.X/30============= ROUTER ======== Z.Z.Z.Z/29 ============ SW 3560==============
(ISP) .253 .254 CLIENT . 47 .48
The connection with ISP or Extra net is a metro Ethernet, so the isp gave two ip address to the client: WAN (/30)
LAN (/29) Which be the public addresses to be used by the client if you need to publish any server on the network (like WWW), so they do not have any device that will could do the nat, like an asa or linux server, so the router has to do the Nat, because the SW 3560 does not support this feature.
So... I did the following:
On router 1841:
inter fast 0/0
description WAN
no shut
[ code ]...
I create an interface Blackpool to simulate the LAN connection (192.168.1.0/24)
Inter loopb 0
ip address 192.168.1.254 255.255.255.0
ip nat inside
[ code ] ...
ON SWITCH:
interface vlan 448
description LAN-ME
ip address Z.Z.Z.48 255.255.255.248
no shut
ip route 0.0.0.0 0.0.0.0 Z.Z.Z.47
But if i try to do ping from the ip address 192.168.1.0/24 to any server´s internet the ping fails, but if i do the ping from v LAN 228 the ping is success. I will think that route map could solve the problem.
I have an 1841 running Advanced Security IOS (12.4(25) I think, have to check when I get home) that I'm using to learn about CBAC and IOS' firewall functionality. Its external interface is connected to my Windstream DSL modem in bridge mode, and the router is doing the PPPoE authentication. It's also doing NAT for my internal network, and is acting as a firewall using CBAC inspect statements and ACLs.
Everything is working at at least a baseline level: the DSL authenticates and connects, and machines on the inside can browse the web. The problem is that browsing to some sites is slow or times out. Not all sites, just some. Latency seems to be okay when doing pings. The problem seems to happen with https connections, but again, not all of them. Gmail works fine (I have it set to always use https), while my bank and credit card sites either time out or take minutes to load.
I have an "inspect https" line in my config, and have allowed https through my outbound ACL.
I'm looking for next steps for troubleshooting this. I've check CPU utilization and it's very low; not sure what else it could be. I only have a few inspect statements, for the common stuff: tcp, udp, icmp, pop3, imap, dns, tftp, ftp, and ntp.
I have 2 cisco 1841 routers the one is connected to my local network and the other is the stub router and it only has 2 fastethernet interfaces. fao/1 connected to the local network and fa0/0 connected to the internet and to the other router. How can i configure NAT on the fa0/0 which is sharing the internet and local network

I have a Hwic 3G-GSM module in an 1841 router. The sim card in the module is configured on an APN no username and password. I have checked all the config from a working router 1841 plus the same module and same vendor Sim card on the APN and all is working. I have configured the second router but it doesn't want to connect at all. If i put the Sim card in a standard 3G modem life is good, and I can connect to the APN and get the static IP address. When I'm trying to initiate the connection from the 1841 the Sim card wont connect.
