Activate nbar2 on Basic Firewall area - cisco 881
IOS version:-c880data-universalk9 - mz.154 - 3.M4.bin
I'm looking to activate NBAR2 on cisco 881 router according to this doc. I couldn't find the command called "nbar - classified" within the following parameter-map command. Appreciate any rear power to solve this problem
card type (config) #parameter - inspect global
You missed this bit important.
In Cisco IOS version 15.5 (1) T and later versions, the firewall area supports Network-Based Application recognition 2 (NBAR2).

Hi all
I am not cisco trained or worked with cisco, im a complete beginner in Cisco platforms. We are an IT support MPH and we have recently taken on a client that has an office abroad using a Cisco 881 device with a Draytek router to the United Kingdom. Site to site connectivity is necessary. I watched and watched videos of youtube on how to configure the VPN and think I have it in place by using the config on the cisco below:
crypto ISAKMP policy 1
BA 3des
preshared authentication
Group 2

isakmp encryption key * address *.

FLOW IPSEC: ipallow /255.255.255.0 /255.255.255.0
Active sAs: 2, origin: card cryptoSo it all seems perfect, however, if I try and ping the remote remote sites over ip LAN router I get the following:
Type to abort escape sequence.
Send 5, 100 bytes toICMP echoes, waiting time is 2 seconds:
.....
Success rate is 0% (0/5)I also can't ping the remote site in the Cisco lan.
I think that it is towards the end of cisco, the Draytek is a basic router and no routing is able to be configured. It does it automatically. The VPN is so no traffic...
Please can someone point me in the right directoin?
Thank you
The additional ip route does not harm even if it is not needed. I love these additional routes that they can serve as a sort of "online documentation" when it is used with a keyword "name" extra at the end.
Your NAT - ACL does not have the traffic. Just add the following:
ip access-list ext 102 1 deny ip
0.0.0.255 0.0.0.255 -
Hi all
just now and with collaboration with Cisco I m right change a network client from the depths. A question was raised on the benefits of changing a core of 6500 to a core of firewall in the backbone of the network. I ve had my doubts about put a firewall in the middle of the network and with the 6500 just for the L2.
Can someone give me some arguments for using a firewall to this customer base?
PS: The customer as many users
Hello
The design with a basic firewall is one who loves a lot of safety engineers.
However the design could easily meet the credentials of a smaller network but a large network with lots of flow and loads of sessions, the advantage of safety could have the disadvantage of the cost high in both the material and the man hours.
in many cases, society has 'only' the new guarantee of an access list and good policy.
In this case, you may be able to do both.
The 6500 has a firewall blade
I came across this in many cases where they just want to have control over access between networks, but I've never used the 6500 Slide since it was just overkill for the task at hand.
So what are the advantages and disadvantages
Firewall kernel
PRO
Excellent control over the traffic that comes and goes in the network
VPN can be used internally
Good security
Lack of support from the protocols
Disadvantages
Costly in both equipment and man hours
Risk of becoming a bottleneck (Slow/news sessions/s)
Don't like the large stream through it.
Lack of support from the protocols
Switch/router Core
PRO
Transmission capabilities excellent traffic
No problem with the wide-open spaces of data such as backups
Multi protocol solutions
Cost of devices
Disadvantages
Fewer security features? less control in network
By the way more different types off of protocols which can avoid safety devices
And then we have a third option
Kernel firewall collapsed
A kernel with firewalls in the junktions and a heart of switching / routed
Pros
A realistic way to safety in a wide network with flows multigig over large areas.
Several units that gives if you pause cannibalizes the network in another place if you need to be to always follow the important parts.
Disadvantages
Can be an absolute nightmare to manage if it is not tightly controlled since the beginning
Number of units
many change points.
Good luck

Several external IPs on Cisco 881
Nice day
I have a Cisco 881 router on which I am putting in place some NAT to allow external connections on some IP addresses replacing my ISP to connect to some ports on my internal servers. Unfortunately, I'm not a network engineer and something seems to be non-tout to right with my setup.
My ISP, I have IP 184.183.156.98, he was assigned to the WAN port on my router Cisco 881 (FastEthernet4), and I have this working properly. Rules of Port forwarding I have in place that use this IP address work very well. In addition, I have the small block of IPs 184.183.150.161 - 164. None of the port forwarding rules put in place for these seem to work at all.
If you need the full config file, please let me know. This section below seems to be the relevant bits to my question, the entries in bold are the port forwarding rules that I think should work, but who do not seem to.

From what you have posted your config looks very good. Are you sure that your ISP routes these IPs to your external interface?
How do you test it?

Site to site VPN works only on Cisco 881
I have 2 problems with a cisco 881. The first problem is that Vlan2 (192.168.5.xx) cannot access the internet on the outside. But I know that the router has internet, because I can ping the external ip address. The 2nd problem is that I have a set of site to another upward, but when I test the Site to site I get this error:
destination of traffic of the tunnel must be channelled through the crypto map interface. The destination following (s) doesn't have a routing entry in the routing table
192.168.2.0I copied the config form this router from another cisco 881 work, where everything works. The only difference is that this router needs a site to site vpn connection.
My question is how I can get internet on vlan2 and who can I solve the connection to site to site.
Here's the running configuration:

It seems that DNS has failed, because it is indeed happened to internet, but it does not work when internet DNS resolution.
Go ahead and try to ping this 157.166.226.25, and it's on the browser http://157.166.226.25/, CNN.com. Let's try those. Also just in case where to configure a DNS SERVER on your router.

Disable any ZBF just in case.

Hello
I'm trying for our DB setup port forwarding server.
Transfer out to 172.16.10.100 for port 1433 is necessary.
We use Cisco 881 TPG EFM and currently running config like below.
Our public IP is x.x.x.x and DB 172.16.10.100 server.
Internet works fine but port 1433 is no transfer to the server from the outside and I am not able to RDP to the server also gives access to.
Please correct the settings for me.

Cisco 881 can ping internet but computers behind the router cannot
I have a cisco 881, which can ping internet but not of any computer behind it. Computers receive a static IP address, that is why there is no DHCP assigned to any LAN interface. Here's the running configuration:

I see ip nat inside and ip nat outside interfaces configured on. But I don't see any translation of address configured. This would preclude anything inside the unit to be able to access the Internet.

Copy the configuration of Cisco 881 to Cisco 2901
We replace our router Cisco 881 with a Cisco 2901 router. If I backup the configuration of the 881 and restore it on the 2901, will there be problems? We just want our 2901 to work the same. Thank you.
routers/switches etc. can with a base image which may allow only certain features the devices come with these out of the box so that they work.
You can buy advanced ip services images or images of advanced security that will allow all the features work. For example, you cannot use BGP or ACB unless you have an advanced picture, but you can be allowed to use RIP and EIGRP stub.
You can check what is running on your 881 with a license to show what it will tell you what is on

endHello @[email protected] / * /;
Thank you for your message. I had a glance on the configuration for you. You used a network as opposed to a wild card mask in your access control list for your NAT statement. This changed the field from the source to 0.0.0.0 automatically, which is going to be does not match your interior traffic and NAT'ing outside.
To fix this, please run the following commands and test once more.
no access-list 101access-list 101 permit ip 192.168.1.0 0.0.0.255 any

Want to update IOS through the Rommon mode in router Cisco 881
Hi all
I'm not able to upgrade IOS via mode Rommon in Cisco 881 router as FE 4 port is in router only L3 and rommon mode it supports of 0 - 3-way only.
So please confirm for me that is there any other way or Cisco 881 router will not support IOS via Rommon upgradation.
Kindly help.
Hi charrier you do not give the ip address of the router interface he gets in rommon so it should not matter what interface, as long as your pc and peripherals, same subnet to push the tftpdnld - see doc
http://www.Cisco.com/c/en/us/TD/docs/routers/access/800/software/CONFIGU...
EDIT: See this too good examples even syntax for 800

My Windows 7 Action Center indicates that Windows and McAfee Antivirus & Firewall are both disabled. McAfee analysis shows that everything works. Looking @ my control panel shows Microsoft Firewall is enabled. Can someone tell me why I started getting these messages that no protection exists? Thank you.
Kind regards

Hi James,
1 did you change on your computer?

Interface issues Netgear Smartswitch to the Cisco 881 LAN port
Hi, we have 100 routers Cisco 881 in our network and they work all fine for the Linksys, 3Com, switches etc. The problem we encountered is interfacing to switches from Netgear. Netgear switches use automatic detection on their ports and it doesn't seem to be compatible with auto MDIX detection on the LAN Cisco 881 4 serial ports on the router 881 hub. Someone has encountered this problem before? A cross over cable solve the problem? Since both executed MDIX autosensing they never synch - so probably a cross on would not make much. I see this with all Netgear smartswitches. If you put a small switch between the Netgear switch and router Cisco 881 everything works well except to pass traffic to port 9000. Any ideas would be appreciated.
See you soon,.

Hello
There should be no problem using crossover cable. You can try disabling autoMDI/MDIX (not auto mdix) on the cisco device and keep a straight cable but if it fails, use a crossover cable.

Cisco 881 - Access Gateway VPN session
Nice day
I configured my Cisco 881 and finally has surpassed "thecan't see my network" issue IPSec VPN.
I have a usecase where I need to access the gateway of the VPN Session.
When I connect to the VPN using Cisco VPN Client 4.8 x, I do not return a default gateway on the VPN map. When I try to ping my IP from the LAN (10.20.30.1) bridge that does not work and I cannot access it with other tools.
I'm sure it's an ACL question and it makes sense to hide the default gateway, but the big question is how to configure my router to see the gateway and access them from the VPN session?
Please see my attached cleaned configuration.
Network Info:
- Internet Internet service provider gateway: 192.168.68.1
- DNS: 192.168.2.1
- Address WAN Cisco 881 at: 192.168.68.222
- Address on Cisco 881 LAN: 10.20.30.1
- DHCP for LAN on Cisco 881: 10.20.30.10 - 10.20.30.50
- DHCP for IPSec VPN: 10.20.40.10 - 10.20.40.50
Thank you in advance for your help!
Kind regards

Cisco 881 - maximum number of VPN tunnels allowed?
Hello
I know it sounds simple and easy question, but I can't find the answer anywhere - so here it is: -.
I need to know the maximum number of vpn tunnels that can manage a Cisco 881.
(In the context, we have a group of users who work from home and office, so their laptops have the cisco vpn client, I need to know how much of these vpn connections the 881 can manage both before, he died a death)
Host-, I read somewhere a line that State maximum number of users is 20 but believe it was referring to a VOIP service.
Thanks in advance.
The 881 supports 20-tunnel IPSec:
