Cisco IOS DHCP Server + classless static routes on DHCP clients

Hi, I tried to find if it is possible to add the ability for static routes to DHCP clients on the Cisco IOS DHCP configuration mode. I'm looking to add a parameters as defined in RFC 3442, like this one, located on the ISC DHCPd server:

Global settings:

121 = integer table 8 code option rfc3442-classless-static-routes;

ms-classless-static-routes option code 249 = integer table 8;

And for the subnet declaration:

option rfc3442-classless-static-routes 24, 192, 168, 30, 192, 168, 10, 1;

option 24 ms-classless-static-routes, 192, 168, 30, 92, 168, 10, 1;

Is this possible?

Thank you!

Vitor

Yes, the fun part it is to convert it into a format IOS will accept. You can try:

IP dhcp pool 0

option 121 24.192.168.30 ip 192.168.10.1

option 249 ip 24.192.168.30 92.168.10.1

If this does not work, change the "intellectual property" for "hex" and each of your decimal byte converted to hexadecimal.

Configure Cisco IOS CA Server message

When you create the CA IOS server, when the database url command has been added, I received the message (in blue below).

QUESTION: What does this message mean and how do I send the declaration? How can I move the existing database to the new location? What is the location of the source? Advice would be good but would appreciate greatly accurate cli!

Thanks again

If you specify what type of files are the NVRAM, the message disappears, for example, if you tell the router to save the CRL on the NVRAM the problem disappears.

Cisco IOS server certificate - is it supported on routers 857/877

Please can someone confirm if the certificate of Cisco IOS server feature is supported on the Cisco 857 router. We have checked with the Software Advisor and no picture for the 857 when the server certificate of IOS feature is selected, but advancedIpservices image v 12.4 (11) T arrives to the 877.

The two 857/877 supports IOS server Certificate

to 857 you need the ADVANCED SECURITY feature set 12.3 (14) YT

http://Tools.Cisco.com/ITDIT/CFN/dispatch?Act=feature&ImageID=619356&platformFamily=306&featureSet=8&featureSelected=2208&availSoftwares=iOS

877 offers more IOSes with Certificate server supports when I chose the certificate server Cisco IOS feature with featured navigator I got a lot of IOSes supporting this feature

Go to navigator feature

http://Tools.Cisco.com/ITDIT/CFN/JSP/index.jsp

Select search by function and select element Cisco IOS Certificate Server, you can filter the results by platform (857/877)

Cisco IOS SSL VPN on mobile

Hello

I want to know can I use the Cisco IOS SSL VPN on the use of mobile client Anyconnect. If yes what is the prerequisite, is there any kind of additional license required.

Thank you

In the following article:

http://www.Cisco.com/c/en/us/support/docs/security/AnyConnect-VPN-client...

Q. is possible to connect the iPad, iPod or iPhone AnyConnect VPN Client to a Cisco IOS router?

A. No. it is not possible to connect the iPad, iPod or iPhone AnyConnect VPN Client to a Cisco IOS router. AnyConnect on iPad/iPhone can connect only to an ASA that is running version 3,0000.1 or a later version. Cisco IOS is not supported by the AnyConnect VPN Client for Apple iOS. For more information, refer to the section security devices and software support to the Release Notes for Cisco AnyConnect Secure Mobility Client 2.4, Apple iOS 4.2 and 4.3.

Add a static route to a RV042

I have configured the RV042 dual WAN port for backup smart link connected to two different ISPS. The subnet behind this is 192.168.2.xxx. I have a second router linksys Garland with the 192.168.2.250 WAN port and subnet behind it is 192.168.20.xxx. My problem is that I have a not able to route traffic fron 192.168.2.xxx to 192.168.20.xxx. How can I add a static route so that clients on 192.168.2.xxx can access resources on 192.168.20.xxx?

1. the second Linksys router must be changed of gateway (active NAT) in router mode (NAT disabled) mode. With NAT the LAN behind the second Linksys will be not accessible from the outside unless you configure port forwarding.

2. on the RV042 set up a static route for the subnet 192.168.20.0/255.255.255.0 to the gateway IP address 1921.68.2.250 on the LAN interface.

3. Ideally, you must configure the same static route on all clients connected to the RV042. If you don't want to do this, you must configure the firewall on all clients on the RV042 accept ICMP redirect messages. This is important because otherwise all traffic from 192.168.2. * to * 192.168.20 would be sent to the RV042 and from there to the second Linksys that is unnecessary and could create a bottleneck.

Cisco 877W DHCP does not automatically fill the Windows/Mac customers with DNS server entries

I have a 877W which was operational on Verizon for about 5 years. It never automatically distributed info DNS server for customers who get DHCP issued IP address. I have to manually enter the DNS entries to each client. What happened to other sites where I've got installed on AT & T as well as 877 unified communications.

Here is the config. Thanks in advance for the help.

Hello

Can you try to remove the IMPORT ALL of the dhcp pool

RES

Sent by Cisco Support technique iPad App

Cisco 861 DHCP + public static IPs + NAT/DNAT. Help.

Hello

I used to use a server of self-made CentOS for intranet for my small office, but I have bouth a few days ago a router Cisco 861 to replace the linux machine.

My needs:

1. I have 2 public classes of IP from my ISP. 1 class is limitted 80mbit upload, the other to 30mbit upload. So I need some sort of DNAT to be able to know exactly what intranet computer uses internet great and including a single internet limitted.

2. I need DHCP server with static IP addresses (a computer must always have the same IP address, etc)... I have my needs for this.

3. also I need external access to certain servers on the inside (web, ftp, etc.)

Parameters:

(Dhcp) intranet: 10.11.12.x 255.255.255.0)

1 public Internet: 89.45.204.118 255.255.255.248 (89.45.204.117 as gateway)

Public Internet 2: some other class in the same IP (assume 89.45.204.58/24 for example)

DNS: 89.45.200.1

So far so good, everything seems simple and I can do this in 2 hours on a centos linux box (correct roads, active ip Routing and some rules for NAT/SNAT/DNAT iptables).

But on this new router of Centos... Well, I am not yet able to ping the outside world, nor inside world I'm tired reading the forums, documentation... I want (at the beginning) to a simple scenario: vlan + dhcp, SEA4 with 1 public ip address and ACCESS to the real world. I was not able to reach even not that much.

OK, first of all, here is a copy of the running configuration:

Cisco IOS router 837 - configure DDNS / dynamic DNS

I have an Internet, connected to my Cisco router link. The package that I subscribed comes with a dynamic IP address. I said me, if I need remote access in the Cisco router, I need to enable the DDNS function. Is this possible on a Cisco router? I have been informed that this feature is not supported. Please help me

Hi Bro

Yes, Cisco ASA and Cisco IOS router supported DDNS. Just make sure you have the right version of IOS, which you could refer to this URL of Cisco http://www.cisco.com/en/US/docs/ios/12_3/12_3y/12_3ya8/gt_ddns.html#wp1202953.

Please refer to the config below made with dyndns.org.

!

hostname INT-RTR1
!
IP domain name dyndns.org
8.8.8.8 IP name-server
!
IP ddns update DynDNS method
HTTP
Add http://ramraj: [email protected] / * //nic/update?system=dyndns&hostname=&myip=>
maximum interval of 30 0 0 0
minimum interval 30 0 0 0
!
interface Dialer1
IP ddns update hostname INT - RTR1.dyndns.org
IP ddns update DynDNS
!

Note: hostname = INT - RTR1.dyndns.org was the host added/registered in the dyndns.org site.

Note: Press Ctrl + V, then just type the symbol? When to add the CLI adds http://___ above.

Note: ramraj:cisco123 is simply an example of an IDs in dyndns.org.

Cisco IOS - access remote VPN - route unwanted problem

Hello

I recently ran into a problematic scenario: I am trying to connect to a remote LAN (using a Cisco VPN client on my windows xp machine) my office LAN and access a server there. The problem is that I need a remote local network access at the same time.

Remote LAN: 172.16.0.0/16

LAN office: 172.16.45.0/24

Topology:

(ME: 172.16.10.138/25) - (several subnets form 172.16.0.0/16) - (Internet cloud) - (VPN-Gateway) - (172.16.45.0/24) - (TARGET: 172.16.45.100)

To provide access, I configured a VPN to access simple distance on a 1700 series router. It's the relevant part:

(...)

crypto ISAKMP client config group group-remote access

my-key group

VPN-address-pool

ACL 100

IP local pool pool of addresses-vpn - 172.16.55.1 172.16.55.30

access-list 100 permit ip 172.16.45.100 host 172.16.55.0 0.0.0.31

(...)

The configuration works fine, I can access the 172.16.45.100 server every time I need to. However, the problem is that when the VPN connection is connected, Windows wants to somehow rout the packets intended for 172.16.0.0/16 through the VPN tunnel. This is apparently due to a static route that added by the Cisco VPN Client and all other specific VPN routes.

I suspect that the culprit is the IP LOCAL POOL, since when the VPN is connected, debugging of Client VPN log shows something like "adapter connected, address 172.16.55.1/16. Focus on the part "/ 16". I checked the VPN status page and the only road indicated there was "172.16.45.100 255.255.255.255" under remote routes. Local routes was empty.

Is this a known problem I missed the obvious solution for? Is there no workaround apart from the pool local vpn penetrating high-end 10.x.x.x or 192.168.x.x? Thank you in advance for advice or tips!

Hello

The best way is to avoid any overlap between the local network and VPN pool.

Try 172.17.0.0/16, is also private IP address space:

Please rate if this helped.

I can't find the ip address of the print server on my router, DHCP clients

I got the wireless-g WPS54G print server at a yard sale and have downloaded the Setup Wizard. Everything looks fine until step 7, select print server. Could not find anything.

Before that, I tried to access the print directly through its ip address server, but can't get it. I checked all the IPS on the main router and found everything except the print server.

Everything is setup, more than once, exactly as defined in the steps of the installation wizard.

I have Windows 7 and a computer laptop 64 bit.

Any suggestion would be great. I already spent 2 hours on this thing and am determined to make it work. All the lights on top of the blink/light print server as it should when they should. I was not wireless yet, still trying to get this Setup program.

Thank you

Chris

Connect to the print server with the Ethernet cable to the Ethernet port on the router.

Press the reset on the print server for 15-20 seconds.

You could get the printer test page, mentioning the IP address of the print server.

If this is not the case, the print server and the router to power cycle.

Open the router setup page and check if you have the IP address of the print server in the DHCP client table.

Cisco IOS IPS in router 2921/k9

Hi all

I have a router from Cisco 2921 box database (error C2921/K9) series with BAse IP IOS (IOS SL-29-IPB-K9) image. I want to activate the function of IOS IPS level on this router now. Based on the Cisco Document, I found that I need to purchase a license additional subscripton enale the IPS feature. My querry is-

It will build on the IOS for basic IP base or do I have to change the IOS?

If I need to buy the Licesne subscription, how can I get the part number and the cost for the same thing?

Do I need to purchase any additional module for this as (NME-IPS-K9)?

Thanks in advance for your quick help

concerning

Sunny

Hi Sunny,

You do not need a module (however you might install a module instead function in IOS IPS).

You need 2 licenses:

1 - a 'security' for your 2921 license enable the IPS feature:

SL-29-SEC-K9

License security (paper) for Cisco 2901-2951 (the two system & spare)

(if you don't have a router, but you can order it with the license as a Pack: CISCO2921-SEC/K9)

2 - a signature subscription license, which is part of a contract of "services to SPI.

A "services for IPS" is essentially a SmartNet contract (including the replacement of equipment, to the TAC, etc) more access to the update of the signature.

SKU for that start with CON-SU or CON - SUO and depends on what level of service for the replacement of HW, and if you want a replacement service on the spot.

for example CON - SU1 - 2921SEC - this includes a SMARTnet agreement with 8x5xNBD without on-site intervention

WARNING: I'm not in the sale so you can check with your local sales office or with a partner of Cisco, Cisco. In fact, some partners may offer a signature subscription service that is clean (without cover material).

Customer Cisco IPSec vpn cisco ios router <>==

Hello

I need to implement ipsec vpn for all users of 10-15. They all use the vpn cisco 5.x client and we have a router for cisco ios at the office. We already have a situation of work for these users. However, it has become a necessity which known only devices (laptops company) are allowed to install a virtual private network.

I think that the only way to achieve this is to use certificates. But we don't won't to buy certificates if there is a free way to implement. So my question is

(1) what are the options I have to configure vpn ipsec, where only known devices can properly configure a vpn and all unknown devices are blocked?

(2) if the certificate is the only way. Can I somehow produce these certificates myself using cisco router ios?

(3) someone at - it an example of a similar installation/configuration?

Thanks in advance.

Kind regards

M.

Unfortunately if you connect to the router IOS, there is no other way except using the certificate. If you connect to a Cisco ASA firewall, then you can identify the laptop company using DAP (Dynamic Access Policy).

Static route ISA570W to Comcast gateway/modem

In my view, that it is a question of static route.

I want to be able to connect to the gateway/Modem Comcast (10.1.10.1) using any computer on my network. Currently, I am unable to do this, I am also unable to ping the unit of Comcast. Here's my setup.

Comcast device (SMC8014)

WAN IP: 50.x.x.238

LAN IP: 10.1.10.1 (255.255.255.0)

A single cable CAT5E for:

ISA570W (WAN Port) - (basic out-of-the-box configuration, 1 - WAN, DMZ - 1, 8 - LAN Ports)

WAN STATIC Port info:

IP WAN: 50.x.x.233 bridge (255.255.254.0): 50.x.x.238

LAN IP: 10.1.10.2 (255.255.255.0)

DHCP enabled for bridge VLAN-1 (10.1.10.30 - 99) by default: 10.1.10.2

A single cable CAT5E for:

Cisco SG200 - 50 p (POE switch to serve as a connection for phones and desktop computers)

LAN IP: 10.1.10.3 (255.255.255.0)

For devices on my network to get an IP address from the device of the ISA, ISA is also the default gateway. I have logged on to the device of Comcast and all firewall rules and blocking are disabled.

Here's a copy of my current routing table according to the ISA570:

Destination address	Subnet address	Entry door	*Flags .**	Metric	Interface
192.168.3.0	255.255.255.0	0.0.0.0	U	0	DMZ
10.1.10.0	255.255.255.0	0.0.0.0	U	0	DEFAULT
10.1.1.0	255.255.255.0	0.0.0.0	U	0	VOICE
192.168.25.0	255.255.255.0	0.0.0.0	U	0	COMMENTS
50.x.x.0	255.255.254.0	0.0.0.0	U	0	WAN1
127.0.0.0	255.0.0.0	0.0.0.0	U	0	LOOPBACK
0.0.0.0	0.0.0.0	50.x.x.238	UG	0	WAN1

My desktop (10.1.10.32), so I'm unable to ping or you connect the unit to comcast to 10.1.10.1.

So according to me, that missing me something simple here, it is a solution of static route, or I'm looking for policies of NAT?

Thanks for your help and please let me know if you need more information on my network.

-Matthew-

OK, a few possibilities here.

Did you go through this process for the SMC8014 Bridge mode?
- http://www.handymanhowto.com/2011/08/19/how-to-configure-a-Comcast-business-class-static-IP-address/
I advise to use a different subnet on the LAN of the ISA to the 10.1.10.x interface. The reason is that when you send a request from a subnet of 10.1.10.x behind the ISA to a subnet of 10.1.10.x, your PC and the ISA assumes that the device is on the same network and will not try to route. Consider using the subnet of 192.168.75.x by default on ISA LAN interface.

If you do not step 1 above, then I'm fairly certain that you will not be able to browse the internet at all. If you can browse the internet, but just can't get the Comcast router 10.1.10.1, then chances are 1 step has already been completed.

Static route / network Configuration?

I have a cable modem that connects via Ethernet (eth0) of a configuration for NAT and Firewall Linux box. Another card (eth1) connects to a switch for my cable network (192.168.1.1/24). I added a third adapter (eth2 - 192.168.2.1/24) which is connected to a M20 (192.168.2.2). The server DHCP M20 has been implemented to serve the 192.168.3.1/24 network.

Is there a configuration more simple than that?

Problems reported with the current configuration:

(1) I think the M20 NAT function must be disabled because the Linux machine is. However, disable NAT causes machines on 192.168.3 bad connection to the internet.

(2) I want the machines wirelessly on 192.168.3 to see shared windows on 192.168.1 and vice versa. Currently they do not see each other. If I remove M20 and plug a PC eth2 and set as 192.168.2.2, this machine can see actions on 192.168.1 and vice versa. I think a static route must be set on the M20 so that he knows what to do with traffic to 192.168.1. However, I don't properly because he always tells me I have an invalid route when I try to enter.

(3) is there one another device other than on the M20 motorway which would better suit my needs (adding a wireless to my private/internal network segment)?

Kind regards

Case No.

OK, I just saw the previous thread on this question pop up on the first page,

Valet parking can be defined as an access point only?

I'll try the posted instructions here.
