i have a little 877 router running Version 12.4(24)T2. I want to muck around with an IKEv2 IPSec VPN but i can't find anywhere to configure IKEv2.
I have found some doco that says its under the crypto config, something like router(config)# crypto ike2 ...........
But i don't have that option. Is it anywhere else?
We had a new linux server installed at a remote office yesterday, unfortunately the guy installing the server forgot to change the IP addresses, doh. It's plugged into a C877 and I can see the port is up/up and I see the mac address using 'sh mac-address-table'. The ip address on the server is unknown but it's unlikely to be in the correct subnet for the vlan it's attached to.
Is there a way I can add an arp entry manually to the router, then ssh to the server and correct the ip address? Or is there some other way to establish the IP address of the server? It's gonna be a pain to revisit the office and there's no one there that can get into the server room to do anything from the console.
I want to achieve the following setup:
So basically I have a C877 and a Cisco ASA 5505 and I want to push the public IP of the ISP to the outside interface of the ASA so the Cisco 877 will only be responsible for ADSL and PPPoA. Don't ask me why I don' t use a modem/router instead. I know that is a waste to use the C877 in this way but I want to test the setup.
Right now the config of the C877 regarding ADSL and PPPoA looks like that ( I don't have the ASA connected yet, so all the PC are connected directly to the C877 right now):
interface ATM0 no ip address load-interval 30 no atm ilmi-keepalive pvc 0/35 encapsulation aal5mux ppp dialer dialer pool-member 1
interface Dialer1 ip address x.x.x.x 255.255.255.248 ip access-group OUTSIDEACL in ip nat outside ip inspect FWRule out ip virtual-reassembly encapsulation ppp dialer pool 1 ppp authentication chap pap callin ppp chap hostname xxxxxxx ppp chap password 0 xxxxxxx ppp pap sent-username xxxxxx password 0 xxxxxxx
ip route 0.0.0.0 0.0.0.0 dialer 1
ip nat inside source route-map Nat interface Dialer1 overload
interface vlan 100 is my LAN configured with DHCP.
how I should configure the C877 to push the public IP to the ASA?
I've tried to set up IPSec over TCP with a VPN-Client V5.0.07.0440 on Win 7 64b to my ASA 5520 (Version 8.2(2)16) regarding to

IPSec over TCP activated at the ASA
crypto isakmp ipsec-over-tcp port 10000
and in the transport tap of the VPN connection 'enable transport tunneling' with IPSec over TCP an port 10000 instead of 'IPSec over UDP' The connect timed out with error code 412 And this is my log from the ASA:
%ASA-7-710005: TCP request discarded from 178.x.x.x/53225 to INTERNET:212.x.x.x/10000

I've enabled Cisco "Anyconnect Premium Peers" for client less ssl vpn connections, the obvious catch is that for ikev2 Anyconnect sessions it wants to use up the SSL license pool instead of the IPSEC pool (which I have lots of connection licenses for "Total VPN Peers : 250".
* Is there any way to configure Anyconnect to connect via IPSEC and use an IPSEC license (while keeping the Anyconnect Premium Peers enabled)?
* Do I have to consider 3rd party vpn clients, outside Anyconnect?
I've ASA 5520 with 8.4(3) running.I want to set up VPN remote access using following document url...I managed to get a connection running, but when I check the connection on the ASA, it shows as a SSL-tunnel, not an IKEv2 tunnel.How can I assure I have an IKEv2 tunnel instead of a SSL tunnel ?Can I do with annyconnect same kind of connections I used to do with the Cisco VPN client for IPSEC?
View 4 Replies View RelatedI have been working for a while trying to get the Linux AnyConnect Client to Connect to the ASA using IKEV2 and EC Certs. I have gotten it to work with SSL, but I can't seem to figure out how to get IKEV2 turned on. On the profile screen (attached) in the ASA when I check IKEV2 I get the cert screen, I check the cert, but then it fails to bring the cert and unchecks the block. The Network Design is simple. ASA IP on high side (outside) 172.20.206.8 with the client at 172.20.206.50. Local LAN is at 10.200.203.0/24.

View 1 Replies View RelatedI have a L2L tunnel setup between two ASA's (v8.4). I used the wizard to set these up and selected the defaults of both IKEv1 and IKEv2, thinking that it would select one or the other. The strange thing is that now I see a separate session between these ASA's, one for IKEv1 and one for IKEv2. Both are passing traffic. Is this expected behavior? Should I disable IKEv1 to force only v2 since both are v8.

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.
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'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?

- An Aruba access point trying to set up a tunnell back to controller through the ipsec tunnell, on udp 4500

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?
