Cisco :: 3825 - Unable To Establish VPN Session With Aggressive Mode Disabled
Jun 6, 2011
I am trying to diable aggressive mode, for security reasons. I have a Cisco 3825 running c3825-advsecurityk9-mz.124-24.T2.bin. When I disable aggressive mode with ROUTER(config)#crypto isakmp aggressive-mode disable , I am unable to connect. The syslog message displayed is > %CRYPTO-5-IKMP_AG_MODE_DISABLED: Unable to initiate or respond to Aggressive Mode while disabled and the client error is Reason 412: The remote peer is no longer responding.
i'm having a problem establishing a pppoe session with a 1812 router. i've tried everything i could find online, even contacted the isp (all they said was that the modem should be in bridge mode, which it is).
I have Cisco ASR 1002, code XE 3.4.1 doing site-2-site VPN with an ASA managed by another company that I have no control over running 8.3 (I think).the site-2-site vpn is very easy straight forward as follows.
Currently, I have in a number of remote sites (with dynamic public address) a C800.On this Cisco, I have a config for initiating an agressive-mode tunnel to a central ASA.relevant part of the config:
Now I need to replace these C800 by ASA5505. But I don't know how to replace the "crypto isakmp peer address" command in ASA.The C800 transmits both the password (abcdefg in my example) and the fqdn (remotesite1 in the example). how to configure the ASA to build the tunnel the way the C800 did?
I've found an issue with my SRP527W that is prohibiting me setting up a useful site to site VPN. In short, the "Enable ID: Default/Manual" option in the IKE policy screen does not seem to behave as advertised. Not matter what it's set to the remote end always ends up receiving the IP address of the DSL interface as its peer id.
The scenario is an SRP527W with a dynamically assigned DSL IP address connecting to a Netscreen SSG5 on a static IP. I have confirmed that:
- A Main Mode VPN works (but is no use on an ongoing basis due to the dynamic IP)
- An aggressive mode VPN works if the Netscreen has its peer ID set to the public IP of the SRP (....same dynamic IP issue)
However if I try to set a manual Remote ID in the SRP IKE Policy it does not get sent as part of the phase 1 negotiations. Debug logs on the Netscreen shows that it receives the DSL public IP no matter what.
Dumping the router config to XML [URL] shows no sign of the IP address that has been set via the interface (despite the setting visibly staying set in the interface). The rest of the VPN config shows up there.
I am trying to configure site to site vpn between Cisco ASA and Cisco router 3825, I need to establish the vpn connection with an interface that has security level of 90.I followed the procedure shown in the following link: URL.
I'm practicing MPLS and wanna establish a simple LDP targeted session between 2 indirectly connected routers. when establishing this session with loopback IP address of routers, the session is established, but when I tested this session with another router's fast0/0 that is MPLS enabled, the session did not established. I wonder, if a targeted LDP session, needs to be established between 2 IPs that are selected as LDP IDs of respective routers. I made routers to use their fast0/0 IP addresses as LDP ID and the session was established.
you can configure a cisco 1905 router with vpn ipsec site-to-site in an aggressive mode? If so, any link to what I do? The VPN works well, but on site A, I had to configure a crypto map associating the IP address for site B (wich is dynamic), so if the connection on site B broken, I will have to configure another crypto map.
The scenario is:
Site A - ASA 5510 configured as a VPN concentrator and firewall for enterprise.
Site B - Cisco 1905 connected to Internet through a ADSL through a dynamic IP address and starting connection to Site A, bellow is the configuration:
We have an ASA5515 at HQ and multiple sites with ASA5505 units. All of these units are connected via site to site VPN in mm. They also have static ip's.mwe have two sites that we are currently attempting to connect back to HQ in aggressive mode but are unsuccessful.
I am completely baffled by what is going on, on our network. We have four HP C4005 Printers. All of them connected to different switches around the network. About every 1-3 hours they all give the error 49FF09 (which is pretty vague, basically a network connectivity issue). Have to reboot to get rid of the error, then it will work again for an hour or so and give the same error (whether print jobs have been sent or not). This started a few days ago out of no where.
I am starting to think its an issue with the network, because they will all go offline at the same time. If I run a constant ping to them, they will all go offline at the same time and return the error. We use all cisco equipment. If I check the port statuses they all say up 100 full with no errors.
I have tried disabling sleep mode on the printers, turned off multicasting, updated firmware for printer and for jetdirect, and used different drivers.
Trying to secure Linksys WRT54G V8 wireless router. Can't change security mode from 'Disabled'!?
I followed this Post from EXPERT: "Connecting two routers wired - the definitive answer"
[url]...
I got the two routers working but the second one (not using it as a router) is not allowing me to change security mode from "disable" to WEP or anything else.The following Post didn't answered this issue: "Can't change wireless Security Mode on my WRT54G V5"
I have installed and setup cisco anyconnect on a win2008 server. It is able to authenticate successfully but upon trying to establish the vpn connection to the asa5520, it shows "unable to establish vpn". Other servers and pc from the same remote site is able to establish the vpn.
We have ASA5510 with version 7.x and asdm 5.X, i upgraded it to 8.3 and asdm 6.2, and i got vpn peers 250 and 2 ssl.when i try to connect through client software , i can see in the logs UDP 500 port is created as shown below.Mar 31 2011 23:54:40 302015 94.97.180.0 57013 x.x.x.x 500 Built inbound UDP connection 56694 for outside:94.97.180.0/57013 (94.97.180.0/57013) to identity:x.x.x.x/500 (x.x.x.x/500) no other things are going on , and i get error as shown below.

i am suspecting it is VPN-3DES-AES activation key issue.when i go to Remote Access VPN ---Advanced---SSL Seetings--From Left Encryption Panel Available Algorithems i have DES-SHA1 when i try to drag it tto Right panel of Active algorithems it gives me error *** below [ERROR] sl encryption rc4-sha1 des-sha1 The 3DES/AES algorithms require a VPN-3DES-AES activation key and currently in right panel of Active Algorithms i have only RC4-SHA1,
I have tried to make a VPN connection between RV180W and iPad with PPTP. I have enabled the server, set the address range, added and user and enabled it.
I entered the same information into iPad but when I try to start the VPN, iPad just tried to make connection and finally fails with an error stating that PPP server cannot be reached.
I think the devices are able to make some kind of connection as if I change the gateway IP address incorrect, I get a different kind of error message. I also tried to reboot the router...
We have two sites, Site-A with a ASA 5520 (Remote Access IPSEC VPN server) at one end and a new ASA 5515-X at Site-B. Users at Site-B are unable to establish a VPN connection to Site-A via Cisco VPN client from behind the new ASA 5515-X. They see the following error:
"Secure VPN Connection terminated locally by the client. Reason 412: The remote peer is no longer responding.
They are able to access the same from home or elsewhere so I believe there is nothing wrong with Site-A ASA vpn config which we have been using for a while now. The new 5515-X (version 8.6) has a very basic config with all outbound traffic allowed. I'm pasting the config below. Do I need to enable/allow anything for it to work?

I am not able to connect to any webpages in normal mode, even after restarting i still have the same problem [However it works in safe mode with networking]. The network connections show that it is connected and the signal strength is excellent. I then have to keep restarting the laptop like 3 to 4 times and it works. Its kind of frustrating to keep doing this all the time and besides i am scared by restarting the laptop so many time can harm it.
I have a sky router (Netgear DG834GT), which i have connected a secound router to which is a D link DIR-615 (with DD wrt firmware D4).I can get access to the sky router remotely without any issues even when changing the port number. its the Dlink router i cannot get access to remotely (within the network i can by typing in the dlink's ip address and works). Main router Sky router IP is 192.168.0.1 - Currently the port number is 8081.Secondary router Dlink IP is 192.168.0.2 (Static ip) - currently the port number is 8080.I have tried to configure the ports but it just dont want to open. Ive tried to open the ports on main netgear and tried all the option my dlink for port forwarding. i must be missing something fundametal here.
I have to unplug/replug my router powercord connection every time i want to use my laptop to access the internet. i have reinstalled the software disc that came with my router. i have have comcast check my modem-
Just doing some basic testing before we replace our ancient PIX 515E with a new 5512. I have a mini lab set up following the diagram below, although I am unable to telnet through to the mail server's netcat listener on port 25 TCP. I can ping all the way outbound from 192.168.101.1 to 10.0.0.2, and the 10.0.0.2 machine shows it is translated properly to 200.225.117.1.
NAT and access rules are as follows:
object network mail host 192.168.101.1 description Mail relay access-list inbound extended permit ip any host 200.225.117.1
[code]....
EDIT: Somehow the new global access rule is involved. When adding a permit any any in there I can get to the mail server no problem. When I remove it but leave in my permit ip any any on the outside interface, I am denied?
Purchased E2500 1 week ago. I do not have a problem communicating with the router itself (either hard wired or wireless) but I have been unable to establish a usable internet connection from the router.I live in building that is wired by Restech Services - Ethernet jack in wall - no modem. Connection works just fine if I bypass router and connect directly to PC (windows XP SP3 desktop or windows 7 laptop.),Very difficult to establish any internet connection at all. I have to renew IP address many times or go through re-boot sequence multiple times. Once I get a connection it is unusable. If I attempt to ping a URL (either from PC or from router admin page) it is unable to resolve host. If I ping an IP directly (either from PC or router administrator page) I typically get 60 to 80% packet loss. As noted, if I bypass router and make internet connection directly to PC - no problems - no packet loss.Used Cisco Connect software to set up. On advice of ISP changed MTU from 1500 to 1300. Also registered MAC id with ISP and changed from cloning PC MAC to using the router MAC. Downloaded and installed latest firmware version. Did factory reset and re-configured the whole thing. Double checked and swapped wiring.
We find ourselves in a difficult situation with the Cisco VPN Client version 5.0.07.0290 where it keeps giving us an
"Error 42: Unable to create certificate enrollment request"
When we attempt to use the Online enrollment method to create and enroll a new certificate. There is no additional information in the VPN client logs where we have set 3-High for all logs. In addition, Wire shark does not show any packets sent from the machine running the client to the Cisco 3825 router which runs the Cisco CA.
To create and enroll a certificate we do the following:
1. Click on the Enroll button to show the Certificate Enrollment dialog 2. Select Online 3. Select <New> for Certificate Authority 4. Enter http://192.168.120.1 as CA URL (note, 192.168.120.1 is the IP of the Cisco 3825) 5. Click Next to display the dialog where we can enter certificate details 6. Enter details in all fields except IP Address and Domain 7. Click Enroll which shows a dialog with the Error 42 ... message in it.
If we attempt to create a request by using the File method, all works fine, that is, the client creates a file with the enrollment request. The fact that the client does not send any messages to the Cisco CA leads us to believe that we have a problem on the client machine. However, the client does not write any information in the logs, so it is a bit hard to fix the problem. I can provide additional configuration information if required for both the client and the Cisco CA. Note that we have not modified any client configuration. Basically, we installed the client on a Windows 7 64bit machine and attempted the steps listed above.
I have 100+ 3750's that are running various IOS, some stacked and some not, and all seem to have the same problem.If I attempt to paste a configuration into the terminal session I get booted after about 10 to 15 lines. This happens when using SSH and Telnet. Telnet will go a little further before I'm booted. After I'm booted it sometimes takes a minute before I can log back into the switch. Any issues pasting configs into a 3750 via a VTY session?
IP routing is disabled on the 3750 (it's acting solely as a switch) IP routing is enabled with an EIGRP process running on the 3550 router that has the network for the 3005 broadcasting.
I can ping the vpn 3005 concentrator from a telnet session in the 3550 but not from the 3750.I can ping between the 3750 and the 3550 vlan management interfaces. Visually speaking it's like this
I know this because I tracerout to the 3005 from the 3750 and it resolved the default gateway configured for the 3550 properly but then started timing out.
The 3750 is trunked to the 3550.
3750 is vtp client mode 3550 is vtp server mode
I'm wondering if there's a layer 2 issue involved here as it is a VTP domain and maybe it's not returning properly.
we're running 4 c4500 Switches at 2 sites connected to each other via Layer-2 crypto boxes and VPLS in a point-to-multipoint configuration which ist completely transparent (it's more or less like connecting them via a Hub - every switch sees the other 3 ones as neighbors). Our basic configs have udld globally enabled in aggressive mode. I wanted to disable that for the interfaces (routed ports) to the crypto boxes, because I don't want them in ErrDisabled for 5 minutes if there are connectivity problems in the VPLS-cloud (every switch also had 3 UDLD neighbors because of the P2MP configuration). In if-config mode I could do this simply with "udld port disable", but I thougt it would be better to run normal mode (not aggressive) to have the chance to use the UDLD show-commands. So I configured "udld port" for the affected interfaces.
I am unable to set VTP mode on my layer 3 switch on GNS3. Below is the snapshot of show version output ? Can you see anything wrong with the IOS image?
I have cisco 2600 router. The problem is my router ios has been crashed and i unable to use any mode on my router. I need to install new ios. How can i install or upgrade new ios step by step.
I configured the below config in Routers it is working good , but when i do the same in SWITCH-2960 , i am getting a problem not able to login to enable mode ... i am getting the basic login only ....
Error msg : % Error in Authentication.

I just received a Cisco Aironet 1130 AG wi-fi router to configure and when I entered the router through console, I am not able to get into config mode. It says:

Also,

Also, this is what I see in my flash:

I need to configure this device and set up for wi-fi access in my organisation network.
Opening a connection to integrated AP801 wireless device for performing wireless configuration tasks, the connection is established OK, authentication is passed OK using credentials from main configuration file, gaining level 15 privileges with enable command, but after that... no way to enter "Global Configuration mode" because there are no "configure" family commands present!!! Simply can't say "Conf t" because there is no such command!
