Cisco VPN :: VPN 3000 Setting Two Concentrators At Different Sites To Create Ipsec Tunnel
May 20, 2011
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 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'm setting up a IPSec Tunnel between 3800 and 2600 routers over the internet.
Do I need to create a tunnel interface as they suggest in this document? [URL]
I just watched a couple of you tube videos saying I don't need to do that...

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.

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.

We have to setup an IPSEC tunnel for a client that does not what to exchange private IP address information for security and overlapping address space reasons. We will both be natting our source private ip address space as public IP address space and send those packets through the established tunnel. Im using a Cisco 3000 concentrator.

We are planning to use an ASA 5540 to terminate about 3000 IPSec connections. The maximum supported IPsec VPN Peers for this platform ist 5000, so this should be ok in theory.
What is a bit unclear to me is what exactly happens when (for whatever reason) all 3000 clients try to connect at once ? Perhaps it's not at once but depending on timers this could mean 3000 incoming IPsec connection within 10-20 seconds.
Will the the ASA cope with it ? I can't find any info regarding this on CCO. It's also not that easy to test/simulate.

I'm setting up an Ethernet network of Rockwell Stratix switches (badged Cisco 3000 series with extra firmware) and need a switch to obtain a gigabit port to a server as the Stratix switches only have 2 gigabit ports per switch and the network is in a ring. The Ethernet ring is in fibre and I would want copper to the server. The switch would need REP (Resilient Ethernet Protocol) to be compatable with the Stratix set up. Is the ME 3400G-2CS AC a workable option?

I have 3 sites. Each site has a Cisco 1841 as its WAN router with a 10Mb direct internet access circuit connected to Fa0/0. The sites are then connected to each other via site-to-site IPSEC VPN. (The LAN switches in use at each site are Cisco 3750 series) [code]
Now, Site A has already been set-up with VoIP telephony. The plan is to extend this to the other 2 offices.Auto QoS has been set-up on the switches and data and voice VLANs created in the same way for each office.
how should/do we extend the QoS for the voice over the WAN to ensure voice quality remains for site to site calls. And what special considerations do we have to make for it being IPSEC VPN connectivity between the sites? The actual IP telephony system itself is being set-up by a 3rd party and not a lot of information on their requirements has been forthcoming so far – essentially all we have really been told is that they would like us to “reserve” a certain amount of bandwidth for the voice traffic between each site.

I'm dessigning a network and this is my scenario:
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?

One of the customers has deployed Cisco 7609S in their infrastructure for Branch/RO connectivity. When we tried to configure per-tunnel QoS with DMVPN for MPLS connected sites, we came to know that Cat 6500 and Cisco 7600 series routers don't support this feature.
Now, we are looking for suitable replacement of Cisco 7609S. I found a document for configuring above feature on Cisco ASR 1000 series routers, but it has many restrictions always.
We are now looking for
(a) suitable platform in the league of Cisco 7609S which support above feature.
(b) suitable technology replacement of DMVPN with minimum restrictions.

We currently run dual ASA 5510's in A/S config on our main campus. We would like to create a VPN tunnel to a branch campus. Trying to decide between a 5505/5510/5512x, We would like to extend many of the capabilities of our network to the branch campus which will be 20-50 users on a 50mb/10mb internet connection.
Domain login
System Center workstation management
Cisco WCS
Shoretel voip
(Cisco NAC?)
Several different VLANs for wireless guest, student traffic, staff traffic, voip traffic, etc. Which device would be best and should we get the security plus license with it?

We are having two sites seperated by half a mile and we are using dedicated 100 Meg link at the moment for intranet traffic, and now we got new 1 gig link and I am working to set it up, Service Provider came on site installed two circuits on both sites and fiber connectivity is tested succesfully betweeen sites, now I need to connect the circuits to our network and make the 1 gig link active to make traffic flow between sites and as well bring 100 meg as standby.
So to brief the issue:
Connectivity at the moment SiteA: Switch1(3560)------100Meg--------.SiteB: Switch 2(3560)
I Want to configure SiteA: Switch 3(4507)------1gig (Active)--------.SiteB: Switch 4(3560) SiteA: Switch1(3560)------100Meg(Standby)--------.SiteB: Switch 2(3560)
simple as connecting a fiber or ethernet link from external circuit on both sites to respective switches on their interfaces and configuring hsrp to enable redundancy. A

I have two cisco ASA 5505 devices and two cisco switches plugged to ASAs in each office. I need to create a VPN tunnel between two offices.
-Network behind the ASA1 in office1 is 192.168.1.0/24 with DHCP server – 192.168.1.10
-Networks behind the ASA2 in office2 are 192.168.5.0/25; 192.168.5.128/26 and 192.168.5.192/26
All computers in office2 need to get IPs from DHCP server 192.168.1.10. I have switch in office2 with 3 VLANS and I can assign computers from different subnets to different VLANs.How can I archive this goal? Should I assign 3 IPs for ASA2 inside interface (192.168.5.1, ...5.129, ...5.193) as a default gateways for each subnet? Should I put dhcp helper address 192.168.1.10 on the switch for each VLAN?

Unfortunately, it does not appear as if the SRP500 series will allow you to create an ipsec policy where the local or remote traffic selection is 0.0.0.0/0.0.0.0. It wants a specific network. I have a scenario where I want to send all traffic over the vpn tunnel.
Is there a workaround to this or a special way to input "ANY" as the remote network?

I need to create multiple ip-sec vpn tunnels on A Cisco 837 ADSL Router. I am able to create one tunnel but the second connection is asking for the outside interface which is atm and already taken by the first tunnel. How can i create more tunnels?
Secondly, after creating the first tunnel i am able to access the remote lan network but when i tried tracert "remote lan ip of a pc" from my pc i got "request timed out" after passing my 837 but succeeded to reach the target. Does tracert needs something to be opened in the router?

We have asa 5520 with 8.4(2) release and asdm 6.4(5). When we create new ipsec connection profiles (by ipsec wizard for example), ASA reset all vpnclients sessions active. Now we need to create new profiles, but we have 170 vpnclients sessions active, so we cant'.

- Ipsec tunnell between two 881's
- An Aruba access point trying to set up a tunnell back to controller through the ipsec tunnell, on udp 4500
- Even though traffic shouldn't be NAT'ed (and other traffic is not), udp 4500 is NAT'ed
I guess this might be default behaviour, thing is that it used to work when it was set up as a route based easy vpn.

We have a Cisco 2820 that serves as a hub and our spokes are Cisco 871s. Its been working for a while and for some reason last week. Http and https traffic over the tunnel is having connection issues. I can Remote desktop or PCanywhere into the remote PCs. From that PC I can ping internal IP address or IP of the webmail server or internal webserver with no issue. But if I access it over the browser it times out or it will work and stop working again. Basically ica, icmp, pcanythere, rdp traffic works over the tunnel but not http or https.
