Replacement of a Cisco router

Hello

I plan to replace a router No. 2851 to one of our sites, but am a little concerned by the configuration of the VoIP on it. Wouldn't be enough if I just copy the current running configuration than one that is for the new router taking into consideration differences in interfaces between old and new routers?

Thank you

Hello

Yes, you can copy and paste the config from the old to the new, as long as you replace it with the same type of router and the same components of voice.

Cisco router 892 IPSec initiator?

Hi all!

I have the IPSec tunnel between Cisco router 892 (c890-universalk9 - mz.154 - 3.M4.bin) and Cisco PIX 515E (ver. 8.0 (4) 28) with 5 subnets behind PIX.

PIX configured to deal with two-way-type of connection, but router support not =)

So, when I generate intresting hosts behind the router traffic IPSec does not work. When I generate traffic hosts behind PIX , everything works, but I need to be initiator on the side of the router :-(

Is there a way to make my initiator 892 tunnel Cisco IPSec router to work with Cisco PIX / ASA?

I'm afraid I should replace the router to another device = (())

Thank you!

Hi Yura Kazakevich,

Try to enable pfs on the router:

map SDM_CMAP_1 1 ipsec-isakmp crypto

Set of pfs

Hope this info helps!

Controller of domain and DNS behind RRAS without VPN connected directly to the internet with a Cisco router

I hava a ME Cisco 3400 with physical single port available for a cable connection.

The ISP give me an IP address interface = 89.120.29.89 to act as a gateway to the IP Address of the host, which is provided for in the order 89.120.29.90.

The host computer is a dual Xeon computer with two NICs for LAN and WAN.

Fields of application: to install a windows 2008 R2 between public and private network server.

Even though I know it's not recomanded, I put the DNS role and directories Active Directory roles installed on the same computer, the computer above, (I do not have enough computer for roles different place on different computers)

The desired configuration:

To have installed with his roles behind a WS2008R2 has RRAS. without a VPN.

b with VPN

and for WAN access for the client computers of the private LAN Windows 7 OS. (The basin of LAN address 192.168.0.1 - 255).

First step : to have internet access in the browser (I use Google chrome) (without taking into account the DNS and AD)

Network configuration:

I'd like to find the password for my Cisco router

I can't connect to my network wirelessly on my ereader, because I don't know what is the password when asked.

Read the manual for the device (Cisco router) should tell you what the password by default is to manage the router (if this does not work... it should tell you how to configure the default router, so you can use the default password to reconfigure) so you can go and change the password to access wireless to something You know.

Cisco router linksys e1000 wireless

a friend of my sister bought a cisco router (see the above subject line). Unfortunately, I was not home at the same time. Currently, there are a desktop wired to the router and a laptop with a Wi - Fi connection. The person who set up the router I forgot the username and the password of the router (didn't even bother to write this info). I convey my computer laptop home from work where I had a connection to internet/router. My laptop (Dell classroom business), I can see the two connections without wire (secured and unsecured comments). When I try to connect to the secure connection I do not get any screen of security, connection, etc., guests. He said something like 'try to check the security info' - do not remember the exact verbage. Anyway, I can not connect. The signal strength is strong - the bars are green. Can connect to the connection of comments, I am not always invited for any connection and safety info. Run the ipconfig/all command confirms the connection. I have still no internet access. Don't know why, but the signal strength readings 'poor' - a single green bar (while the secure connection shows all the force green signal bars). I have installed / configured several wireless - never had a problem. I need to recover the connection info router without having to perform a hard reset on the router (I have same access limitted in my house of sisters/partners where the router). Is there a way to do it. I spoke twice to the cisco technical support and received two different answers (not according to the first call, open Explorer, go to programs/cisco for the info). This must be done on the computer that was used to install the cisco installation disc). Help, please!

There are a lot of things I want to share with you on your router E1000 installation:

1 E1000 comes with an installation CD that has CIsco Connect (the icon looks like a house) to easily manage your wireless network (you can easily get your password for the Cisco connection). Cisco Connect (CCC) is generally accessible to the computer that is first used to install the router (maybe this is why the tech officer ask you to go to the computer used to install this)

2 E1000 broadcasts 2 signals of the main network and - network of comments. Once you click on the name of the network, you can easily connect the guest network seems to be unsecured However, when you access a Web site you will be asked a password. Always secure line.

3. you can actually access to internet but not wireless cable but to the router.

4. If you don't have the computer used to install the router, you must reconfigure and the first thing to do is to reset the router. You must configure manually if you do not have the installation cd.

PowerConnect 6248 switch for Cisco router

Hello

I'm new to this forum and I have a problem at the moment between a Cisco router and a dell pc6248. The problem is that I lost conectivity in VLAN 1 when I connect the router to a trunk port in the switch, however I conectivity VLAN 2 through this link to trunk. The configuration of the switch:

interface ethernet 1/g48

switchport mode trunk

switchport trunk allowed vlan add 1-2

output

interface ethernet 1/g43

switchport mode access

switchport access vlan 2

output

On router

fast interface 0/1

no ip address

no downtime

fast interface 0/1.1

encapsulation dot1q 1 native

IP 192.200.3.1 255.255.255.0

fast interface 0/1.2

encapsulation dot1q 2

IP 192.168.51.33 255.255.255.248

output

With the above configuration, I lost conectivity with the host in the vlan 1 - 192.200.3.x/24, but I win conectivity VLAN 2, when I connect the router to the 48 trunk port in the switch. This means that the trunk link for VLAN 2 work but not for VLAN 1.

I read on the port of general mode, where I can configure the pvid of the port as 1 (vlan1) and it would be the unttag VLAN (even natively in Cisco), and I can configure the VLAN 2 like the tag, all this in the same port. What do you think about this? Someone have set up something like that?

Best regards

Erasmo

PD: I write from Chile, I apologize for my English.

I agree with you, I would try the general mode on the PowerConnect switch.

mode console # switchport general

Console # switchport General allowed vlan add 2 tag

Console # switchport pvid General 1

Cisco router WIFI does not work after turning off the power

I have a CISCO router that worked very well until someone turned off the power for a few minutes. I tried to unplug the modem, the router and the laptop and waited a bit. Then I turned on the modem, then the router, then my laptop but it is still not in communication with the modem. I can use the modem with a hard connection to the laptop but need the WiFi as well as others can use it. Help, please.

You need to contact support with your Cisco router. It looks like it might have been reset and the installation needs again.

Internal and external customers see certificate of Cisco router, NOT Exchange SSL certificate

Cisco 876 Integrated Services router (ISR)
Exchange Server 2010 SP1

Customer: 2013 Outlook, OWA, ActiveSync WP7/WP8 (?)

Put us in place a new Cisco ISR. Almost everything works fine, with a few exceptions. Exchange e-mail stopped altogether for several days until I realized that I needed to redirect the ports, SMTP, HTTP, and HTTPS, by external to the Exchange Server. Now, mail flow is fine, but...

Every time I start Outlook, I get a certificate error. When I look at the certificate in the error popup, it points actually to certificate self-signed Cisco router. When we try to use the Windows phones, they get a "certificate error" and direct the user to the network administrator. Even with OWA: a certificate error, even if it can be "accepted" / overridden.

Each customer can still work, with the exception of Windows phones. In Outlook and OWA, mail is always be sent and received, but must be accepted manually that the certificate is wrong before the customer takes care, and then it takes a little longer to load.

Any ideas?

I did "" port forwarding on the pots of 25, 80 and 443. Again, I did it yesterday and now mail seems to flow, whereas before, even if we could enter the client with Certificate error, message not be received. (There was also a problem with mail however not passed, but that was due to our mail relay provider and was set yesterday as well...)

Everything worked fine with the previous router (obviously). It was a high-end, the level of consumption Fritz! Box commonly used in Germany. I also had to allow ports through this box is not unlike using the nat ip inside static commands on the 876, but I don't know what he could have let his own or why SRI is the Exchange Server application SSL certificate hijacking.

Thanks in advance for any help.

If we have actually figured this out today. The internal DHCP Server distributing the a DNS Server public as well as the internal DNS. The internal DNS was time and the customer became the external IP address of the public DNS and it received an unexpected cert of the router. Once we removed the public DNS servers from the DHCP server and used only DNS servers in-house, that the issue went away. Logical after we realized what was going on.

How to distinguish the physical interface and logic (subinterface) interface to the Cisco router/Switch?

Hi Expert,

How to distinguish the physical interface and logic (subinterface) interface to the Cisco router/Switch? Can you please clarify a formal way for this so have?

A physical interface is numbered with the same name of the interface when printing on the physical port. For example "GigabitEthernet 0/1" corresponds to port 1 of the 0 module (or the base unit).

A logical interface can be a subinterface on a routed port and will have a point ("". "") preceding the number sous-interface (ex. GigabitEthernet 0/1.1). It can also be a loop or a virtual interface (on a router this could also include interfaces like the tunnel and virtual tunnel or VTI types). A switch may also have a VLAN logical interfaces (e.g. interface vlan 1) which are used as layer 3 virtual interfaces of type.

No network on computer - 2 routers, 1 no CISCO router.

Hi guys!

I hope someone can help me with that.
First some information about what material I got.
I got a Cisco 860VAE router, I didn't get no cable from the console (so I'm connected to telnet), I got a home router also (got it from my ISP).

I use my router I have of my TV service provider, so I can't remove it just... boring...
I was getting the Cisco router because I am a Cisco CCNA student at my school (first year) and I thought it might be cool to NetFlow

The router I got from my ISP is quite advanced so not a lot of options here. In any case, it uses the 10.0.0.0/8 range IP
Then my CISCO router uses the ip range 192.168.1.0/24

The problem is that I can't connect to the internet from my computer (I know...)

Let me show you my config(remember I'm NEW) race:

It's not like I can configure RIP on my ISP router if... ? And BTW, my cisco router only support RIP as the routing protocol
Then what should I do?

You need to configure nat on the Cisco. I'm assuming that the ISP router connects to G0 on the Cisco. The ISP router probably does not know on your subnet 192.168.1.0/24 and you can't nat several subnets in their router anyway. You need to with the Cisco nat address 10.0.0.0/8 on Cisco.

access-list 100 permit ip 192.168.1.0 0.0.0.255 any

IP nat inside source list 100 interface g0 overload

int g0

NAT outside IP

int vlan 1

IP nat inside

Get rid of these:

IP route 10.0.0.0 255.0.0.0 GigabitEthernet0

IP route 192.168.1.0 255.255.255.0 Vlan1

You don't need them because these two subnets will be seen as connected routes.

You will also need to add a default router in your dhcp pool:

IP dhcp pool ccp_pool

default router 192.168.1.1

And you can get rid of this line as well:

by default-gateway IP 10.0.0.100

L2TP/ipsec passthrough firewall of cisco router

Hello! I have the following problem.

External network users wish to connect internal Windows to network and share resources 2012 (start the software, files, etc)

So it's time to deploy a vpn server and as I did not have a free license to run on my windows 2012, I decided to use my qnap for it (because it has this built-in feature) so I chose l2tp/ipsec and tested on the laboratory at home with simple tplink router with upnp function and it worked like a charm.

However, in the real production environment, I need to use the cisco router, and this is how the story begins ;)

Thus, clients with their machines say (7, 8.1, 10) must pass router cisco (with nat) firewall and access a vpn server and the internal network on qnap.

I googled for sample configuration, but most of them related to the configuration of the router as a vpn server, and I want to achieve is to make my pass router vpn traffic. Once I found the same sample of pptp config, I have modified it a bit, but do not know if it works because I have not yet tested.

In any case, could you check my config and see if it's ok? I'm doing a static nat for vpn 192.168.5.253 server to external address?

Also, here is a short pattern

vpn client VPN server (win 7,8,10)---routeur cisco 1921 - qnap)

Once the client has been connected to the VPN, you want traffic back to flow to the client. Which can be easily received with "inspect".

And from the point of view of the firewall, you do not have ESP-traffic (which would be the IP/50). You have only UDP traffic (initially UDP/500 which goes into UDP/4500)

And you are right with your last ACE. That of a lot to permissive and not necessary for this function.

Cisco router access outside the local network interface

Hi all!

I have Cisco router 892 (c890-universalk9 - mz.154 - 3.M4.bin) with firewall area and based on routing strategies.

Everything works fine, but now I need to have the ability to access external router interface IP LAN addresses.

For example, I PAT 192.168.4.1 port 8443 to the outside interface IP (93.93.93.2 for example) and I need to check LAN 93.93.93.2:8443.

! PAT:

IP nat inside source static tcp 192.168.4.1 8443 93.93.93.1 - extensible 8443 SDM_RMAP_1 road map

! DynNat to the internet:

IP nat inside source overload map route SDM_RMAP_1 interface GigabitEthernet0

! Routing policy

SDM_RMAP_1 allowed 10 route map
corresponds to the IP 101
match interface GigabitEthernet0

! ACL 101 for routing policy

Maybe someone can help me to make Cisco to allow ports outside LAN using a NAT?

I did this on Mikrotik easily = |

It is due to the fact that they do not allow "hair pinning" by default, once this is configured, it will work.

AAA authentication in Cisco router

I want to create the user name and password with the level of prévilige for each user in the Cisco 3640 router. I don't have any authentication server, and I want to use the local database of the Cisco router to do this. Can someone suggest me how should I proceed.

Thanks in advance

Hello

If you want to create users in the local database of the router, you must use the following command

username cisco password privilege 5 test

AAA new-model

AAA authentic login default local

AAA exec default local author

Cisco router: RV110W

I am installing a Cisco RV110W router in my network, currently I have a service contract with TalkTalk broadband, which uses PPOA to connect to the internet. They advised me to put the router in that had mode bridged, what I've done. Te router that they provided is a D-Link DSL-2680.

After plugging the ethernet to the WAN of the Cisco port cable and port LAN 1 of the D-link I can't get the Cisco to initialize the internet.

I select the PPPoE function in the Cisco router, however, when you use the D-Link router, it's usually a PPoA VC Mux connection. It doesn't seem to be an option to select a PPPoA connection in the Cisco router.

When it try to connect there is no response from my modem/router in Bridge mode.

I would use the Cisco router with my current router in this way. If this is not possible, I would like to give the address IP of Cisco have all computers on the network through the Cisco route before arriving to the internet enabling my firewall and access control setting etc to work. I don't know if this would work but that I would use the VPN and QoS options on the cisco too.

Is it possible to have the D-link router/modem function normally and connect the LAN of the D-Link port to the LAN/WAN port on my new cisco to achieve without forcing cisco to connect to the internet and to recognize the connection?

Any help is very appreciated.

Here you can see the Cisco GUI; Launch the emulator from device online

The different subnet mask thing that should not be, it was just to avoid having two routers using the same network, which has taken care of by changing the 2680 to 192.168.0.1.

You're right about the strange gateway on the WAN connection, it should be 192.168.0.1 (2680). I think it might be the problem, because your pings are never power the 2680, the RV110W routing table sends those 192.168.0.2 for some reason any.

I'm going to put in place here at home so I can go on it as well, in the average to make sure that you have power cycled at least once, and you might want to try resetting the RV110W and setting up again (what you have done so far has been correct) sound silly I know but sometimes things just stuck.

I put the same scenario here right now, and I'll see if I can make it work.

Oh and the only ping you were missing was the 2680 WAN IP address, but since you can't even ping the router LAN port, it, it won't work anyway, so don't worry it.

NPS Windows Help for authentication of aaa for Cisco router - is it safe?

I am very confused about how all this works and was hoping someone could help me.

I followed a bunch of tutorials online for authentication RADIUS of installation on a Cisco router and he did to a NPS Windows Server. Now I can ssh into the router my AD account.

Now that I got it to work, I go to the settings to make sure everything is secure.

On my router, the config is pretty simple:

aaa new-modelaaa group server radius WINDOWS_NPSserver-private 123.123.123.123 auth-port 1812 acct-port 1813 key mykeyaaa authentication login default local group WINDOWS_NPS

ip domain-name MyDomcrypto key generate rsa

(under vty and console)# login authentication default

On the NPS Windows:

I created a new RADIUS client for the router.
Created a secret shared and specified Cisco as the name of the seller.
Created a new strategy of network with my desired conditions.
And now the frame of the configuration of the network policy that worries me:



So initially I thought my AD credentials were being sent over the wire in plain text, but I did a capture and saw this:

How is my password being encrypted and how strong is the encryption?

Another thing is how can I configure aaa authentication with mschapv2? The documentation I saw for mschapv2 uses the "ppp authentication ms-chap-v2" command, but I'm not using ppp I'm using aaa with a radius server.

Hello

RADIUS encrypts the password, but sends the username in clear. GANYMEDE encrypts the user name and password.

You can find the encryption used by RADIUS in the RFC scheme:

https://Tools.ietf.org/html/rfc2865#page-27

MS-Chap-V2 is used for the authentication of users such as the remote access and vpn, not management switch
