Successfull in setting up an L2TP/IPsec tunnel through NAT-T against a Windows 2008/ R2 RRAS server? I am using an 881 router and the layout is someting like this:Client -> 881 -> NAT -> internet -> Windows 2008 RRAS.The tunnel goes form the 881 to the Windows server (not from the client...).
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 in process of purchasing a new Cisco routers for our branches that will be used primary to enable IPSec virtual tunnel interfce with "tunnel mode ipsec ipv4". does the default IOS IP Base supports this feature? or i need to purchase DATA license or SECURITY license?
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.

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?
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?
I have a newly aquired asa 5505 that I just set up to the bare minimum configurations. I followed a cisco paper on how to create a "remote access vpn" setup for ipsec. I can sucessfully connect and establish a VPN, but when I try to access an inside resource from the vpn address, the asa blocks it.
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'.
I am trying to create a VPN tunnel between two RVS4000 Routers through a WAN. I get the following error when trying to do so. "remote Security Group" and "Local Security Group" can't be in the same network.
- 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.
can I force an IPSEC L2L tunnel to use NAT-T encapsulation no matter what? Automatic detection says none of the endpoints are behind NAT. I know I can disable it by the "crypto map XXX set nat-t-disable" command, but I want the exact opposite.
I have a very strange issue where asynchronos routing is making my life as a technician very hard.
A side question; Can I do something about an ISP that is policy-base-routing its ESP traffic (and/or translating it)?
I'm attempting to configure a tunnel on a PIX-501 version 6.3. It's an old device that's due to be replaced soon, but unfortunately we need a tunnel now... I have been using this document as a reference (6211): URL ,The remote end is a sonicwall.
The problem seems to be that the pix never sees the interesting traffic for the tunnel, and never tries to initiate a connection. I have enabled crypto ipsec and crypto isakmp debugs, but no data is ever displayed, even when attempting to access a device on the remote side of the tunnel! Someone had tried to set up this device with some tunnels in the past, but was never successful, so I'm thinking there might be remaining commands in the running-config causing problems.
configuring some static NAT entries on a remote site 887 router which also has a IPSec tunnel configured back to our main office.
I have been asked to configure some mobile phone "boost" boxes, which will take a mobile phone and send the traffic over the Internet - this is required because of the poor signal at the branch. These boxes connect via Ethernet to the local network and need a direct connection to the Internet and also certain UDP and TCP ports opening up.
There is only one local subnet on site and the ACL for the crypto map dictates that all traffic from this network to our head office go over the tunnel. What I wanted to do was create another vlan, give this a different subnet. Assign these mobile boost boxes DHCP reservations (there is no interface to them so they cannot be configured) and then allow them to break out to the Internet locally rather than send the traffic back to our head office and have to open up ports on our main ASA firewall.
So I went ahead and created a separate vlan and DHCP reservation and then also followed the guidelines outlined above about using a route-map to stop the traffic being sent down the tunnel and then configured static NAT statements for each of the four ports these boost boxes need to work. I configure the ip nat inside/outside on the relevant ports (vlan 3 for inside, dialer 1 for outside) The configuration can be seen below for the NAT part;

Im able to create a gateway tunnel with two rv042 routers in different locations ( i can see the tunnel connected in the router) but the quick vpn utility is not working , i also tried to use the pptp as server as an alternative( im able to connect using windows connection to the pptp server but whenever I browse any of the four ip's allowed for the pptp server \10.0.0.200-204 it takes me to the documents of the local computer....I attached the configuration for one of the routers it is the same as the other end , just the information is flipped.
I have been struggling for a few days with getting site-to-site traffic working across a L2L IPSec tunnel. At this point, I have the tunnel up, and I see packets being decrypted on the correct IPSec SA's when I ping from a local network computer on the ASA side to a local network computer on the router side. I cannot ping from one side to the other, but those packets are getting through. We have another L2L tunnel that is from that ASA to another remote site's ASA, and that is functional. I have mirrored the configuration for ACLs, etc. from that site, so I believe that the issue is with the packets getting incorrectly translated by the NAT/NONAT statements/ACLs on the router side.
since a few days I'm trying to solve a problem. I've successfully established an IPSec tunnel between two local LANs. In the main office I'm working with a ASA5510 CLI 8.4 and a static public IP address. The branches are using different Cisco 8xx routers and dynamic public IP address. The following picture shows the current configuration:As I mentioned an IPSec Tunnel between the main office "Intern"-LAN 192.168.1.0/24 and an outside LAN 10.10.0.0/24 is successfully established. Now there is a new intern "Admin"-LAN 192.168.2.0/24 at the main office. The users from the outside LAN 10.10.0.0/24 need the possibility to reach this new intern "Admin"-LAN.Can I simply route the traffic from 10.10.0.0/24 to 192.168.2.0/24 via the existing IPSec-Tunnel? Or need I a new IPSec tunnel between the outside 10.10.0.0/24 LAN and the new "Admin"-LAN 192.168.2.0/24?
I have an ASA5510 configuration that I'd like to add to.In this configuration there is a site to site IPSEC VPN tunnel to a remote location.It is tunneling a particular subnet for me and everything is working.In the remote subnet, there is an ASA 5525-x connected on the outside interface. Let's say for argument's sake, the outside IP is 22.214.171.124.On the Inside interface, i've configured 10.240.32.0/24 network.The only static route I have configured on the 5510 is the default gateway that goes to the ISP.I assumed that I have to add: route Outside 10.240.32.0 255.255.255.0 126.96.36.199 1.I did this, but i'm not able to reach the destination 10.240.32.0/24 network. I can't see anything hitting the 5525-x and the only thing I see on the 5510 is the building outbound ICMP and the teardown for the ICMP.
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 a site to site IPSec tunnel setup and operational but periodically the remote site goes down, because of a somewhat reliable internet connection. The only way to get the tunnel to re-establish is to go to the remote site and simply issue a ping from a workstation on the remote network. We were having this same issue with a Cisco PIX 506E but decided to upgrade the hardware and see if that resolve the issue. It ran for well over a year and our assumtions was that the issue was resolved. I was looking in the direction of the security-association lifetime but if we power cycle the unit, I would expect that it would kill the SA but even after power cycling, the VPN does not come up automatically.
I have running more the 30 VPN tunnels on my ASA5540 release 8.3(x).I want to disable one VPN tunnel(temporarily) without removing the configuration either Phase 1 or Phase 2.let me to know the command to disable IPSec VPN tunnel on CLI or ASDM.
I'm having trouble configuring an ASA5505 on version 8.31 code for an IPSec tunnel. I've done this multiple times on 8.2.5 but can't seem to get my tunnel to even attempt to come up on this ASA. Not sure if it's relevent or not, but this remote ASA has never been used for another VPN tunnel before. When I attempt to ping a host on the other side of my tunnel, I just see the following: 8108# sho crypto isa sa
There are no isakmp sas
My local network is 10.1.1.X/24 and my remote peer network contains 66.37.227.X/24. I've been working on this for the better part of the day and would love to get it resolved.
