Cisco VPN :: IPsec Between AS5505 And Netscreen 500
Aug 7, 2011
I have a established VPN between NS500 and AS5505
The following diagram shows whats going on.
customer source subnet: 192.168.2.0/24
Source NAT to 10.160.64.33
NS500: sub int 1.3 : 10.160.64.1
Destination NAT to : 199.53.28.17 <-- this is a server IP which allows telnet on specific ports. The source has to be 10.160.64.33 to pass the firewall.
In the same way a new connection is required to another server IP behind a firewall.
target is going to be : 159.5.250.194/32
The source for this connection has to be 159.5.188.40 in order to pass the firewall and hit the above target.
After upgrading a couple of AS5505 to asa8.41 and using ASDM-641 I have been unable to set up a Site to Site using the Wizard.Had enough of a headache doing the upgrades on the CLI. I wait for my PO for Sec+ to clear so I can Add Failover. Ping was enabled and both '05 can ping each other. [Code] .....
I am trying to get up an point to point VPN between a Cisco DPC3925 and a netscreen 5GT Firewall I have configured up everything as i think it should, i belive the phase one and phase two are both configured ok, if i change the phase one settings to something different then i will get a different error on the cisco I am using Auto Ike, with a shared key and PFS - both phase one and phase two are set the same at both ends cisco / netscreen?When I try to connect, the VPN log on the CISCO shows the below, but on the netscreen it thinks that phase one Negotiations are complete (in logs etc) The netscreen seems to be much more configurable than the CISCO, so i guess i need to change something on that, what the cisco is expecting to receive ftom the netscreen that its not getting from the logs, I have chaged the external IP's in this log?

I am working on cisco ACS 5.0, authentication is working fine on netscreen. Can acs be used for authorization and accounting of netscreen devices. if yes, what will be the configurations.
I am new on CISCO but learning. I need to allowing ping from inside interface to outside interface. I need to allow SSH from outside to PIX506E and one node on inside 192.168.66.x. I also need to setup 32 public IP adresses to route inside nodes. I also need converting the rules from Netscreen firewall to PIX506E. Last, getting PDM working when i connect it start two windows but does not get PDM so i can configurate it thru PDM. [code]
I wants to inegrate Juniper netscreen firewall in Tacacs Cisco Acs 5.1.As I go through Juniper KB which mentioned that I need to enable Netscreen Service in Cisco ACS 5.1. how to enable Netscreen service in Cisco Acs 5.1 and how I got Further to integrate Juniper Netscreen Device in Cisco cs 5.1
Several of my older netscreen devices only support radius authentication and I'm having trouble migrating them from ACS 4.2 to ACS 5.1. When I try to authenticate, the authentication passes in ACS but it doesn't log you into the Netscreen (you see a auth failure in the Netscreen logs). I believe that the custom attributes are not being passed from ACS to the Netscreen. The custom attribute we are trying to pass is "NS-Admin-Privilege" with type integer and a value of 2. The netscreen is setup so that the user privledges are obtained from the ACS server.
Any setup where they are using Cisco radius authentication to authenticate Netscreen devices?
I am trying add custom attributes for Juniper Netscreen TACACS+ authentication to a v5.2 ACS. The advice is to add it to the group as follows:
ervice = netscreen { vsys = root privilege = read-write } I know how to add this to a version v4.x ACS
However, I do not know how to apply this to the custom attribiutes to a v5.x ACS?do I add the vsys and privilege attribute seperately or together? What should be the attribute name? netscreen? Should it be mandatory?
I am currently migrating a netscreen firewall to a asa 5515 version 8.6 The issue is setting up the management connectivity.
basically the management IP of the cisco asa is not advertised. But, we want to route a management IP through the management interface to interface Gi0/2.
so IP of management interface is say - 216.10.100.10. and the IP of the inside interface is say - 198.1.1.10/24 on our router we have a static route sending 198.1.1.0/24 to next hop of 216.10.100.10 (management interface of cisco asa).
On the Cisco ASA can I send the traffic to the inside interface and manage the firewall via ssh that way?
I am having some difficulty setting us this vpn connection between our cisco 837 box and netscreen 25.The Phase 1 proposals match and are accepted, then the cisco log seem to go round and round in circles trying the Exchange a Key??? [code]
I'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.
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
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?
We have Cisco ASA 5505 and an internal user (behind NAT) needs to connect via VPN to an external company. I just cannot get this to work. I have enabled IPsec Pass Through from ASDM Configuration --> Firewall --> Service Policy Rules --> Edit Service Policy Rule --> Rule Actions --> tapped IPsec Pass Through I have tried to find some info from the log but all i get is this message: IP = [remote gateway ip] Invalid Packet Detected!"I cant find anything that is blocked from the log.
I'm setting up IPsec for a DMVPN between a 2811 and 2951s in a test lab. I have enabled IPsec on the hub (2811) but I am unable to do so on either of the 2951s. After researching, it seems that I may have the incorrect IOS for this, but I am at a loss which IOS I should be using. Currently the 2951s are on "c2951-universalk9-mz.SPA.151-2.T2.bin".
- 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.
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 found [URL] that it's possible to create IPSec between WLC and MS IAS server. Is it possible to use ACS 5.2 instead of IAS and establish IPsec between WLC and ACS?
I have a cisco 871 router and I have set up an IPsec vpn on it. I can connect to the vpn but once connected I can only ping the router (10.12.0.1) but nothing else on the network. I can access the router via ccp/telnet and from the router I can ping other machines on the network, so I know that they are connected, but I can't access them from the vpn connected machine. Also the vpn connected machine can't access the internet while connected to the VPN. How can I get computers that connect via the vpn to see other machines on the network, and how can they access the internet while connected to the vpn?
Here is the running config:
Building configuration... Current configuration : 6760 bytes version 12.4 no service pad [Code]...
I need 3925 router that support BGP as well as IPSEC VPN. is this correct part number i ordered? CISCO3925-SEC/K9. Its always hard to understand Cisco licensing, specially new one. will above package will have router wth ipbasek9+seck9?
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.
I 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:
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.\
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.
