Cisco Security :: Establish A Tunnel (LAN-to-LAN) From A VPN 3000 Series?
May 31, 2001
Is it possible to establish a tunnel (LAN-to-LAN) from a VPN 3000 series Concentrator with a static IP address to another VPN 3000 series concentrator (or an IOS router) with a dynamic IP address.
Can I configure a PIX (515), as PPTP client to establish a tunnel with non-Cisco PPTP server ? Can my PIX initiate this type of connection ?Today, I use a PC with PPTP client to establish this and I want replace this with a PIX and I don´t want depends of a PC.
Phase1 is complete, Phase2 isn't coming up...everything has been verified on both sides but we're getting unknown errors.

I have Cisco VPN 3000 in main office which provides VPN tunnel to the remote site (PIX 506). In main office we have Domain Controller as well as DNS/DHCP servers.I ran into the issue where DNS reverse lookups are not working from main office to the remote computers:
ping remotecomputer.mydomain.org - works fine from main office and resolves to appropriate IP address ping -a IP address - from main office returns nothing.attdns.com
From the remote computers, both forward and reverse lookups are working fine.
I'm currently setting up two VPN 3000 Concentrators at two different sites to create a IPsec LAN-to-LAN Tunnel. I have gone through all the basic configuration guides on the CISCO site, but a LAN-to-LAN session is never created. I have enabled the logs on the Concentrator and it displays no errors at all - it appears the Concentrator is not even trying to establish a IPsec LAN-to-LAN Tunnel.After running through the standard setup provided by CISCO, is there anything I need to do to make the Concentrator try to create a Tunnel, or should this be automatic once all settings are in place?
I´m getting a dynamic public IP from my provider and what I´m trying to do is to establish a remote vpn tunnnel using IPSec which I achieve but every time the sessions resets or the ASA 5505 resets I get a new public IP and I need to put the new IP on the remote client so I can establish the vpn... How can I establish an ipsec vpn using DNS? For this scenario the remote vpn client is a vpn phone but it could be for any vpn client.

I have remote branches that connect to the corporate office as a site-to-site VPN. Now the clients at the branch are getting an application that is using an unsecured port (tcp/23). I would like to use a set of ASA 5520's that I have at the corporate office, with the AnyConnect license on them. I want the client machines to establish a tunnel from the client to one of these ASA's. The ASA' then would have a connection to the VLAN that the receiving server is housed on. The trick is to just establish the tunnel from the client to the ASA that will allow the IP of the client to not be translated. So I would use the ASA as a security 'pass-through' for the clients that use this new application.
I've been labbing on my asa5505 at home, setting up different VPN solutions for testing purposes. However, I can't get my anyconnect client to establish a DTLS tunnel when connecting (anyconnect only shows tls, and does not display any errors about not connecting with dtls)I have set dtls port to 444 and this port is open on the other side.
I need to check and possibly change which Network address is allowed down a tunnel and check our Phase 2 IPSEC proposal. How would I do this on a VPN3000?
I have a client that needs to establish a IPsec tunnel to a large organization. They will not forward any traffic to an IP using private reserved IPs. However I am not finding another way to accomplish this. I tried ipsec to the router and using a second IP to a 1:1 Nat but it will not pass the traffic and would seem really insecure from the public internet. 1:1 Nat does work from the public internet but not over the tunnel.I have an RV042 a /29 block of IPs. I am at a loss of how I can accomplish what they want without allowing a private IP.
5 - Remote sites (no static IP there) 3 - Remote users (comercial) 1 - Central building (using static ip address)
Is it possible to establish a permanent vpn tunnel between each one of my remote sites to the main building, even if I have no static IP address in the remote sites?
Do you think that RV180 is the best choice to mannage vpn connection between remote sites and the central building securely and faster?
i'm triyng to establish a vpn ipsec tunnel between my cisco2801 and a cyberoam equipment, at the end point.Debugging isakmp, i have this output, where xxx.xxx.xxx.xxx is the remote peer address, and yyy.yyy.yyy.yyy is mine.What can i try?

We have two 3000 vpn concentrators. Under both of their load balancing fields, Configuration - Load balancing , the checkbox for loadbalancing is enabled.However both have different priorities, one with 10 and other with 1. Does this mean both are actually loadbalancing. What does the priorities indicate here?If we replace the concentrators with ASA , how will this load balancing need to be configured on ASA & how will it work.
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.
As you can see i have problems with connecting 2 SRP521W together for an VPN tunnel. I tried as much as I can but now i dont know what to do or how and where is the mistake? the connection between these two devices was there last week, after weekend (nothing changed in configs) the connection suddenly was interrupted, without any reason or warning. another day it worked again and 20 mins later connection was dead again...and now it wont establish at all.. here are some screenshots from the vpnconfigs of my devices. one has a static IP the otherone uses FQDN. These are the IKE policies: Here the IPsec Policies: and the GRE policies:
We have configured a site to site tunnel from our ASA to another organizations Cisco 3030. It appears to have just one way initiation. We can do a ping to a device on the remote site and it will ping just fine. however, when the tunnel needs to be initiated from the remote site, it will not work until we have initiated the tunnel and then everything works.
I continue to see Error processing payload: Payload ID: 1 errors on the ASDM logs.It appears that all the configuration is in place because we can in fact establish the IPSec tunnel unidirectional. And once established, traffic can flow bidirectional.
Last week, I was able to establish a site-to-site VPN tunnel between an ASA 5505 and Cisco C881 router just fine. The tunnel was up and and running for a number of days but today the tunnel is no longer up. I was wondering how, if there are any commands to re-establish or re-initiate the tunnel.
our customer unfortunately uses a Watchguard.Finally we could establish a site-to-site vpn connection.To test if the connection re-establish again, we cleared our vpn session by "clear crypto isakmp <session id>" and after that "clear crypto sa <ip address of the peer>"After that, the session is down on our site, but the watchguard keeps the Phase I still up, either the deleting messages from our cisco are visible in the watchguard log files.Watchguard helpdesk told us, that the messages are only seen as a deletion message for Phase II, therefore Watchguard keeps Phase I up and running.Here you could see the cisco 7206 log messages aftre the clear commands:
In my opinion, it looks ok and we do not have problems with other VPN devices with this kind of tests.what could be done that the watchguard deletes Phase I, too? Or that an explicit Phase I deletion message is created and sent by our cisco 7206?
I have 3 4400 WLC's that implemented at 1 main site within a mobility group. I am looking at implementing wired guest authentication with a splash page for username and password access. I have followed the documents and suggestions about how to configure it. I created a layer 2 vlan (700) and then created a VLAN (151) that wired guests will get an IP address from. I then configured a WLAN with the ingress interface being VLAN 700 and the egress interface being VLAN 151.
All of my controllers are running code 7.0.116.0. When I go to do a test scenario with a wired client, I have the switchport setup for VLAN 151, which they get an IP address from, but when they try to go to the Internet, they don't get the splash page. Why I am not getting a splash page or even if this scenario is possible?
Our requirement with that appliance is to do URL blocking and filtering.Are there any other options we can consider or is it SaaS only. Would have preferred Trend Micro, but don't this is possible with this appliance.Will content security be offered on the Cisco ASA 5500-X Series?At this time, content security services are not supported on the Cisco ASA 5500-X Series appliances. However, the ASA 5500-X Series Cisco Cloud Web Security ready. Cisco Cloud Web Security provides content security as a cloud-based software as a service (SaaS).
Cisco Catalyst 2960 series,i want do a SNMP request over OID. When the output should be like this: Portnumber and VlanID. Is there a OID for this output?
I've configured SSL VPN on an 1811 router running 12.4(9) IOS. I'm using the full SSL VPN client and do not want to split tunnel the traffic. I can reach my inside resources just fine, but I can not reach sites on the Internet. I want to tunnel my Internet traffic to the router and then have it hairpin out the same interface.
I've successfully configured this type of hairpinning on an ASA for SSL VPN, but have yet to find a way to do it in IOS.
I have problem with the Lan-to-Lan VPN tunnel.the VPN working fines since 9 months ago without any problems.Suddenly got the problem!,In last two days we faced problem the VPN down.in first time the problem in phase-2.. but after that in phase-1... in latest no data packet received to their side.
I have a tunnel between a PIX 515E version 7.2(2)and a Cisco 3800 version 12.3(11r). There is a mismatch somewere in the configs but I cannot find it. I have included the configs and the syslog errors.
I have an existing VPN tunnel from my branch office to corporate.I want to allow my employees to establish a VPN connection to our local branch office where we have a local server, and not go through the corporate office.Can I set up a direct VPN connection to my router/ firewall at the branch office, even when there is a VPN tunnel already connected between my office and corporate?
we have a cisco ASA 5505 and are trying to get the following working:
vpn client (ip 192.168.75.5) - connected to Cisco ASA 5505
the client gets a specific route for an internet address (79.143.218.35 255.255.255.255 192.168.75.1 192.168.75.5 100) when i try to access the url from the client i get a syn sent with netstat when i try the packet tracer from the ASA i see the following:
why I can't use cisco ehwic-3g-hspa-u card in cisco 2800 series and 1841 series router?documentation said that it should work with that devices but when I installed it, it doesn't work even as device i can't see I am using cisco latest ios advance ent. 15.1(4)M4?
