I'm trying to setup an IPSEC tunnel above GRE using the topology in the attached image file.However the traffic between the 2 endpoints: lo0 on R5 (10.0.5.1) and lo0 on R4 is traveling via the GRE tunnel without being encapsulated in IPSEC: I'm using 2 routing protocols:
- OSPF area 0 for the connectivity between R1,R2 and R3
- EIGRP AS 1 for the internal sites connectivity
Got some issues when setting up IPSEC/VPN on the asa 5505. I want to connect from the ipad with the built in IPSec client..Get errors when i run the debug crypto isakmp
View 1 Replies View RelatedI am having a tough time getting my VPN client to reach any devices on my office network. I have a Cisco SR520 configured with IPSec to terminate Cisco VPN client sessions. The client is able to connect successfully. I get a username/password challenge, and then I get assigned a pool IP address on the client computer. So the VPN connection looks good at that point but I cannot reach any devices in the office network.

I am trying to configure netflow/flexible netflow on some branch site 887 routers which have a IPSec tunnel back to the main office. It is my understanding that the router will not encrypt traffic that it generates itself so the standard netflow will not work. The workaround I have seen is to use flexible netflow rather than standard.
I have tried to configure flexible netflow with the following configuration;
flow exporter EXPORTER-1
destination 192.168.10.1
source Vlan1

I am not having much success setting up a IPSec VPN tunnel between a RV042 V3 running v4.0.0.07 firmware and PIX 525 running 8.0(4) code.
Let's say the configuration looks like this:
The RV042 has public IP 70.0.0.1 and private LAN IP 192.168.1.1 /24 The PIX has outside IP 69.0.0.1 and inside LAN IP 172.16.0.1 /24 The RV042 is running as DHCP server on it's private LAN A Windows server at 172.16.0.2 is the DHCP server on the PIX's inside LAN.
I've tried every option on the RV042 for Phase 1 and Phase 2, but I am not certain how to configure the Advanced features especially Aggressive Mode, Compress, Keep-Alive, AH Hash Algorithm and Dead Peer Detection.
On the PIX I've tried the basic setup through ADSM, but it's not as clear or obvious to configure both sides with compatible settings compared to setting up a tunnel between two RV042s.
To understand and configuring VPN setup to give secure access to my DB & Application Server exist in my Datacenter, to other Service Provider organisation. They need to access those DB & Application Server sitting at their company LAN itself.
My DC Setup :-
1. Core Router 7609 with SPA-IPSEC-SSC400-1 ( Cisco 6500/7600 IPSec VPN SPA Bundle 1 )
2. Core Switch 6513 with FWSM, ACE, SVC ( Network Analyser ), SUP 720
3. Distribution 6509 SUP 720
All the DB & Application Server connected to Distribution Switch in various VLAN,The Server support team from another company need the access to those, for that we will take MPLS link connecting out Core Router.

I have webcams that need port 8081 opened and I did that, everything worked fine until my DIR655 jammed up and power cycling it and the modem 3-4 times DID not make it work: no internet access and it was definitely a DIR655 problem. So, out with the paperclip to do the big reset, causing me to lose my configuration. When "most" of it came back up with my new config (I had screen prints), all was okay EXCEPT the webcams. Addresses and ports were all configured properly, address was fixed too on the client computer rather than use DHCP. I had a DNS relocation service running (DYNDNS) for the WAN side, but that address (My IP) didn't change either. I tried EVERYTHING. Finally, I realized in all my screwing around that I had enabled UPnP in my application, something I hadn't done before, but did this time as a desperation move. UPnP had always been checked off in the router. So.....I REMOVED my port forwarding and virtual server settings (either one worked before), and voila, everything working, Is this a normal occurrence, that if you have UPnP running, that this auto configuration overrides any manual configuration?
View 2 Replies View RelatedI'm trying to establish vpn session between 2 Cisco 892/k9 routers. but when i apply the crypto map in the GRE tunnel interface this type of message apears.
NOTE: crypto map is configured on tunnel interface.
Currently only GDOI crypto map is supported on tunnel interface.
As the same crypto map is easily applied to the physical interface instead of GRE, and It works too... What causes the problem based on the Debug output and configurations which i have attached with this message.
The VPN connection seems to be etablish but I can not ping the LAN behind the router .I can see the errors with debug ipsec

I want to establish GRE over IPsec tunnel between four branch offices and head office. At branch offices, I have 1841 router with Advanced Security software. At head office, I have a ASA5510 7.2 as frontend with one public IP addres and 1841 router behind it in private address space. Since ASA is not supporting GRE tunnels, can ASA be endpoint for GRE over IPsec? If not, can ASA pass this tunnel to the 1841 router behind it, so 1841 would be logical tunnel endpoint? What should I pay attention? Should both ASA and every 1841 support NAT-T, or just ASA?

- 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.
i have 6 sites using tandberg visioconference system, each site have a cisco router 1841 configured with ipsec vpn, i have a 4 conference a week and my bandwidth is 2 meg, and when people are working we have a lot of problems and cut in our visio conference.
I have a big problem, i want to make a high level QOS priority to my TANDBERG visio conference system between my sites, the issues is that there is an IPSEC VPN in my cisco routers between those sites and as i know if the traffic is crypted we can not separate the packets or give higher priority to packets over anothers.
can i mark traffic in the lan interface and and make a high priority befors the packets go through the ipsec tunnel?

i have started managing a asa 5510 firewall which is already having 10 ipsec tunnels , the problem i am facing is they are configured as "ipsec vpn map"
i have attached sample config, i am finding it difficult to understand the parameters used in each tunnel as the configration seems bit complex to me, how it works .
I wonder if any of you now if there exists a small IPSEC box that can be put between units that don't support IPSEC? I'm not looking for a Wireless router with a WAN port. Only a small box with 2 ethernet ports and IPSEC client support.
View 5 Replies View RelatedI have created a site to site Ipsec vpn with a cisco 2610 and a linksys RV042. Running a show "crypto isakmp sa" command I get a qm_idle status and when running a "show crypto ipsec sa" I see that packets are being decrypted and encrypted. Also when running the "show ip access-lists" command I do have matches to that connection.The problem is that I am unable to ping hosts from one network to another. For example, from the Cisco router in network 192.168.0.0 I am unable to ping the remote network 192.168.2.0 and vice versa.
I am not sure what is happening. Do I need to create a route to that remote network? I guess it could also be a problem with NAT or an ACL.Here is what running-config shows:
crypto isakmp policy 1
encr 3des
hash md5
authentication pre-share
group 2
lifetime 28800
how to create ip sec tunnel using these parameters. customer ip where tunnel has to be connected 1.1.1.1
ISAKMP Parameters: (Phase I)
Encryption: AES-256 or 3DES
Authentication Mode: Pre-shared key
[Code]......
how IPSEC VPN works but i hit a stumbling block understanding symmetric encryption keys.Here is my understanding about the process
1.Peers will negotiate plocies
2.Authenticate using pre-shared or certificates
3.Exchange DH Public Keys
4.Using Public keys encrypt symmetric key and exchange the same key which will be useful for communication
5.maintain sessions
But when we are configuring we will define encryption keys in isakmp phase and ipsec transform set ,i thought we will use the same encryption key for both management and data communication in fact i thought management phase is to give us a securely exchanged encryption key for the data tunnel.But we can use 2 different encryption keys in 2 phase i am bit confused.
why my VPN setup is not working correctly. The device is an ASA 5505 running IOS version 8.2. It has a license for 2 SSL VPNS, and 25 IPSec VPNs. The previous Admin had set up both but only the SSL VPN apparently works. I attempted to set up my own IPSec VPN using the ASDM wizard, with an IP range of 192.168.40.10-50. I am connecting from a Mac, 10.6. My local network (home) is a standard 192.168.1.0/24; the remote networks are 192.168.2.0 and 192.168.3.0. I tried connecting using the built-in Snow Leopard client, and although it said I was connected I couldn't actually contact anything on the corporate LAN.\
