multiple server Raduis on Cisco router configuration

I have a cisco router, who works as a PPPoE NAS Server I need to configure multiple raduis servers each one is dedicated to an interface, so I will each of my clients to authenticate via the server correct raduis

Thanks in advance

Hello

a brief overview of the steps config:

AAA new-model

create 2 separate radius servers, use the modern syntax with host and key in the same line

host 10.1.1.1 XXXXXXXXX RADIUS server key.

radius-server host 10.1.1.2 key XXXXXXXXX

Create 2 separate aaa-servers in a group radgroup1 and radgroup2 and add each of the servers to a server group aaa

aaa group server radius radgroup1

 server 10.1.1.1

    aaa group server radius radgroup2

    server 10.1.1.2

create 2 lists different servers as a method of authentication with groups aaa:

AAA authenticate ppp login1 group radgroup1

AAA authenticate ppp Connexion2 group radgroup2

Use the two authetications on what appropriate interfaces:

Router (config) #interface {name-of-interface-1}

Router(Config-if) #ppp login1 chap authentication

Router (config) #interface {name-of-interface-2}

Router(Config-if) #ppp Connexion2 chap authentication

The incomplete 1941W Cisco router configuration

Good day all.

I was running a business of small ecommerce for the last 5 years on a Linksys wireless router. Now that I have more than 14 posts and 6 networked printers, it was time to take a step towards the top.

I bought a 1941W SRI CISCO to take us to the Gigabit speed in the next decade with a CISCO switch. I assume that the 1941W, although robust with scalability, would provide the installation of it, simple as the product Linksys (Cisco) or at least a simple 1-2-3 How to get basic connections made. I was wrong and now I find that I have some difficulty to negotiate Internet on the router again.

Included below is my config NVRAM. I hope someone could tell where I can have a few gaps in my config.

Please note: this config is derived from an example on the net that seemed simple enough, so if you find yourself asking, "why did do that?", I hope that this provides the perspective.

Thanks in advance to those who consider a response.

You have a LCD 115 on the external interface and it is just a line in this acl which is a refusal. Be aware that an acl has implicit deny all the end anyway so basically that this acl blocking all incoming which responses return icmp (ping) traffic. Because you run the command ping to the router using an IP address not not a DNS then NAT or DNS name is a problem at present.

I suggest that rewrite you the acl - 115

access-list 115 permit icmp host 8.8.8.8 entire echo response

and test again with your ping. If it works then it's the acl that is the problem and you need to write your acl so that is what you want to allow before that you want to deny.

RADIUS server two in 1 Cisco router

Hello

Just need to know if it is possible to use two RADIUS server in 1 Cisco router. The first server RADIUS authenticate remote users to access our internal LAN while the other RADIUS server will authenticate users who will have access to routers. The reason why we cannot use the same RADIUS server to authenticate remote users and users of router is due to our contract with our supplier (long story!).

in any case, if it's possible, could someone help me how to do or give me the link to the documentation.

Thank you

Yes, it's the way to do it. This gives you two different methods, the user.

connection key radius-server 1.1.1.1

RADIUS - 2.2.2.2 key server logon

3.3.3.3 RADIUS server remote key

4.4.4.4 RADIUS server remote key

RADIUS AAA server telnet protocol group

Server 1.1.1.1

2.2.2.2 Server

AAA-server group remoteaccess radius Protocol

3.3.3.3 Server

Server 4.4.4.4

AAA authentication login default group remoteaccess

AAA authentication connection group telnet

line vty 0 4

SUCH connection authentication

Line con 0

authentication of SUCH loging

This is an example which will allow your access telnet to the router to use a server group

while allowing your users to remote access use other radius servers.

Impossible to establish a VPN connection with a router configured as a Cisco server using client VPN 5.0.00.0340

Hei guys,.

Please help me on this one because I'm stuck enough on her...

I am trying to connect to a Cisco 3700 router configured as a VPN server by using a VPN client and the VPN connection does not settle.

This is an extract from the log:

130 12:48:30.585 07/01/11 Sev = Info/5 IKE / 0 x 63000001

133 12:48:30.600 07/01/11 Sev = WARNING/2 IKE/0xE300009B

134 12:48:30.600 07/01/11 Sev = Info/4 IKE / 0 x 63000013
SEND to > ISAKMP OAK INFO (NOTIFY: INVALID_HASH_INFO) for 200.100.50.173

I enclose the whole journal extract... The message "BOLD" is quite obvious, you mean, but I'm 100% sure, in the login entry, I typed correctly the group password: pass

My topology is very basic, as I am setting this up only to get a clue of the operation of the Cisco VPN. It is built in GNS3:
-2 3700 routers: one of them holds the configuration of the VPN server and the other would be the ISP through which the remote worker would try to establish a VPN connection. I am also attaching the configuration file for the router configured as a VPN router.

Behind the second router there is a virtual XP machine on which I have installed VPN client...

My connection entry in the customer is to have the following parameters:
Host: 200.100.50.173 , //which is the IP address of the VPNServer
Authentication-> authentication-> name group: grup1 password: pass / / I'm quite positive that I typed the correct password... even if the log messages are linked to a misidentification.

I use public addresses only, because I noticed there is a question about behind the NAT VPN connections and is not not very familiar to the NAT.

Another aspect which can be of any importance is that "allow Tunneling of Transport" in the tab Transport to the input connection is disabled

and the VPNServer router logs the following error message when you try to establish the connection:

* 01:08:47.147 Mar 1: % CRYPTO-6-IKMP_NOT_ENCRYPTED: IKE 200.100.50.34 package was not encrypted and it should have been.
* 01:08:47.151 Mar 1: % CRYPTO-6-IKMP_NOT_ENCRYPTED: IKE 200.100.50.34 package was not encrypted and it should have been.

You have no idea why I can't connect? Y at - it something wrong with my configuration of VPN server... or with the connection entry in the VPN client?

Thank you

Iulia

Depending on the configuration of the router, the group name is grup1 and the password is baby.

You also lack the ipsec processing game that you would need to apply to the dynamic map.

Here is an example configuration for your reference:

Hope that 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).

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:

Try to do a topology of MY ISP text-> router ISP-> Switch-> CISCO router-> workstation

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.

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:

capture.jpg


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

Thank you

Client VPN Cisco router Cisco, MSW CA + certificates

Dear Sirs,
Let me approach you on the following problem.

I wanted to use a secure between the Cisco VPN client connection
(Windows XP) and Cisco 2821 with certificate-based authentication.
I used the Microsoft certification authority (Windows 2003 server).
Cisco VPN client used eTokenPRO Aladdin as a certificate store.

Certificate of MSW CA registration and implementation in eToken ran OK
Customer VPN Cisco doesn't have a problem with the cooperation of eToken.
Certificate of registration of Cisco2821 MSW ca ran okay too.

Cisco 2821 configuration is standard. IOS version 12.4 (6).

Attempt to connect to the client VPN Cisco on Cisco 2821 was
last update of the error messages:

Is there some refence where is possible to find some information on
This problem? There is someone who knows how to understand these mistakes?
Thank you very much for your help.

Hey guys, it's weird that the router is not find cert after IKE is the cert and validates, it is certainly not reason, but I would go ahead and set up the mapping of certificate on this router to force the client to associate with Group of IKE, for that matter, that you need to change your config a bit for use iskamp profiles :

Multiple VPN connections using 871 router

Hello

I have the cisco router 871 at the site of the retail that connects to the corporate site. I also want to connect a device to the sharing network partner, but it needs to connect to their virtual private network. Is it possible to configure the 2 VPN connection to 2 different company sites in this scenario?

Thanks for your help.

Umesh.

Hello

You can configure multiple VPN tunnels on the router (whether on the same interface or different interfaces).

You can then perform the traffic from a tunnel in another tunnel, if you must do the same.

Need some advice about the VPN between local Cisco router and remote Watchguard

Hi all

I am configuring a Cisco 887 to VPN router to a device of watchguard at the remote site.

From what I understand, the VPN tunnel is in PLACE. I can ping to the remote server on the 192.168.110.0 of the network, but whenever I try to navigate to it on the local server, it wouldn't work.

I ping the remote server via the IP address on the local server, but not on the Cisco router. Is - will this work as expected?

Crypto ACL 102, should really include only 1 line, that is to say:

10 permit ip 192.168.0.0 0.0.0.255 192.168.110.0 0.0.0.255

and you should have the image mirror on the remote end ACL line too.

PLS, remove the remaining lines on 102 ACL ACL.

I guess that the ACL 101 is NAT exemption, if it is pls include "deny ip 192.168.0.0 0.0.0.255 192.168.110.0 0.0.0.255" on top of your current line "license".

Clear the tunnels as well as the NAT translation table after the changes described above.

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

Keep us updated.

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!
