Cisco VPN :: EzVPN In 7606S With SPA-IPSEC2-2G?

Aug 23, 2011

I'm trying to configure a router 7606S with SPA-IPSEC-2G for EzVPN.I was reading some examples in SPa and 7606 documentation but with the current configuration in our router I don't know how to do it.
 
The router has the SPA installed in slot 3, interfaces G3/0/0 and G3/0/1.  The router has the interface G2/0/0 connected to our provider, and we have the interfaces connected directly to network; ie:  not vlans, no trunks,  ports configured as IP ports conected directly to network.Where can I find an EzVPN example configuration ?

Cisco Switching/Routing :: 7606s Power Coming From Single Supply

Apr 6, 2012

Having a strange issue here with an 7606-s chassis equipped with two sup720's, and two regular line cards. There is only one power supply, PWR-2700-AC. I recently builded this setup and powered it on last week for the first time. It ran fine for about 20 minutes while suddenly the chassis powered down.
 
I've checked the back of the chassis and noticed that the power supply had it's 'input ok' and 'power fail' led lit. I toggled the power switch and waited half an hour to power it on again. This time only 1 minute of joy. My first idea was the PSU due to the power fail led so I had it swapped by the supplier for another. Unfortunately, when I powered it on today, it didn't change a thing, still unexpected power downs.
 
So I've checked the following documentation: [URL] and followed the suggestion to power the chassis on without any modules in the slots. So I did that and it ran for 8 minutes only. However, the fan tray did respond properly when I removed the small thermal module in the upper right by increasing the fans to full speed.
 
Following above documentation, it points to the chassis (there is not much left). Now the real question comes, isn't there anything else that could be the cause of this?

Cisco VPN :: ASA 5510 - Configuring With EzVPN?

Nov 1, 2012

I'm having trouble configuring with EZVPN on ASA5510. EZVPN uses the local LAN as the source IP, now since the EZVPN is configured on the ASA, it will use its local port 2.2.2.1 as the source local LAN. The actual local network is behind a firewall and i need the tunnel to extend to the 10.10.10.10 network. Is there a way to extend the tunnel to use the 10.10.10.10 as the source LAN? How to do it via the GUI?

Cisco VPN :: EZVPN Between 2811 And SR520 Flapping

Mar 31, 2011

I am having an issue get an EZVPN working between a 2811 server and a SR520 client. The symptoms are the SR520 makes multiple connection attempts to the 2811.  It appears that sometimes these connections are successful and the SR520 is assigned an IP address but then the tunnel will be dropped and a new session will be started.  I've attached scrubed configs for both the 2811 and the SR520. One other note, when connecting to the 2811 with a software VPN client, there are no problems, so I think the problem is with the SR520.  On the other hand, the SR520 wasn't having any problems until we switched our VPN server from a UC520 to the 2811.

Cisco VPN :: 3825 IOS EZVPN Client Timeout

Jul 10, 2011

I have a 3825 configured as an EZVPN server with 881 routers as clients.  One issue I am seeing is that sessions don't seem to time out, such as when a peer's public IP changes.  Show crypto ISAKMP peer shows the same host (using device certificates for authentication) with multiple public IPs establishing sessions.  I have ISAKMP keepalives configured on the router.

Cisco VPN :: 5580 EZVPN Using RRI And NEM With Fa0/0 And Loop Back0

Mar 29, 2011

Our company has a handful of sites that use the EasyVPN technology.On my remote router (Cisco1841) - I add the crypto inside to the FA0/0 and the Loopback0 interface.On the other end my Cisco ASA 5580 - 8.41 code - I have RRI enabled and the tunnel comes up fine.However I only see the static route from the fa0/0 interface on the remote router.  I can not figure why I can not see the Loopback0 address?Wondering if this is a limitation or feature not enabled.
 
I added multiple interfaces on the Cisco 1800 and can see the networks.I run "show crypto ipsec sa" on the Cisco ASA and see the spi encaps/decaps for the loopback, but the SH ROUTE does not show the static route being injected.

Cisco VPN :: 857 / EzVPN Sometimes Ping Only In One Direction Or Interface

Jan 14, 2013

I have lots of 857's routers in the field with mostly the latest OS - 12.4(15)T17 making ezVPN connections to a 2951 with 15.1(4)M5.All the 857's have lookback and vlan interfaces similar to :
 
interface Loopback0
ip address 50.43.8.1 255.255.255.255
ip tcp adjust-mss 1452
end

[code]....
 
Now lately for some or other reason we have instances where I can ping either the VLAN or the LOOPBACK interface, but not both. Or I have instances where the 2951 can ping all the interfaces on the 857, but the 857 can not ping the 2951. Or I have instances where the 2951 can not ping the 857, but the 857 can ping the 2951.The way I have been fixing this is either to add crypto ipsec client ezvpn SMS_VPN inside to the loopback interface, or if it is there already to remove it. This usually works for a few days, but then suddenly I have to reverse this again. If that does not work then I usually do lots of clear crypt sess and/or clear crypt ipsec client ezvpn on the 857, or clear crypt sess remote 857_ip_address from the 2951 and then suddenly it starts working again.

Cisco WAN :: 857 EZVPN - Cannot Ping Anything From Remote To Server

Mar 14, 2012

We have a VPN using 857 and 877 routers as remote connecting in to a 2800 EZVPN Server.

The VPN is working fine. However, the VPN connections sometimes (after a few hours/days) seem to "freeze". A "show crypt sess" shows the connections as Up/Active, but you can not ping antyhing from remote to server, or visa versa, nor does any traffic flow. I then added a "isakmp keep-alive" on the 2800, which improved the situation a bit, but not as much as I hoped.
 
On the 877 I then implemented a IP SLA, with Object Tracking and then use a Event Manager to just issue a "clear crypto session" . This solved the problem.
 
However, what do I do on the 857 ? It does not support Object Tracking or the Event Manager. Is there any other mechanism to monitor and reset these frozen/stale VPN connections automatically ?

Cisco VPN :: Client Behind EzVPN Remote (ASA 5505)?

Feb 2, 2012

I try to configure a simple EzVPN infrastructure:
 
EzVPN Server (CISCO2811, hostname cme) < -- > EzVPN Remote (ASA5505, hostname ezvpn-asa) < -- > Client
 
Attached you find both configuration of the EzVPN server and remote. The tunnel is getting up and if I ping from the ASA to the Router, I see the packets getting encrypted:
 
ezvpn-asa# ping 172.16.100.1
...
ezvpn-asa# show crypto ipsec sa
interface: outside
Crypto map tag: _vpnc_cm, seq num: 10, local addr: 172.16.100.2

[code]....
 
If I connect a client with IP address 192.168.1.2 to the interface eth0/1 and do a ping to the cme, I don't see any packets getting encrypted. I don't have any idea about VPN, I just need it for a wireless lab environment. What do I have to configure on the ASA, so the inside traffic is encrypted?

Cisco VPN :: Configure 2 EzVPN Groups On 2811?

Apr 2, 2013

configured 2 EzVPN groups using a 2811 router, i am trying to do this but is not working i have another VPN working thru EzVPN but if i try to configure another group for another EzVPN client is not working and the problem is  that the debug crypto isakmp say that Apr  3 08:45:25.802: ISAKMP:(1309): phase 2 SA policy not acceptable!
 
How is that possible? in my understand the EzVPN server will inject the the IKE (phase 1) and IPSec (Phase 2) parameters for the client and that's they dont need to negotiate nothing, is important to say that the EzVPN client is an ASA5505 with onlu DES encryption enabled, 3DES and AES are not available due to licensing reasons.

Cisco :: Get ASA To Advertise EZVPN Connected Networks Via OSPF

Feb 16, 2011

I'm trying to advertise the branch LAN subnets via OSPF back to our core.I can create the OSPF adjacency and the ASA is learning routes fine. However it does not appear to be pushing the branch LAN subnets to the connected router. show ospf database reveals they're not in the OSPF database.Here is my routing config, the branches are 10.114.0.0 /16.As an aside, why I need the statics below, they appear to be necessary to reach my LAN subnets behind the EZVPN spoke sites. I would have thought the ASA would learn it automatically as I'm running network-extension mode on the spokes. [code]

Cisco VPN :: Cannot Access Remote LAN On EZVPN With DVTI 1841

Mar 18, 2011

configured Ezvpn Server/client with client mode configuration on IOS router with ver advipservicesk9-mz.124-15.T3.bin of ISR 1841 routers. Only my main issue is that once the tunnel is up I cant access the server side local LAN. However I could each site my icmp traffic is encrypt or decrypt but not both at the same time. However I can ping from the server to the client ip address which is assigned by the pool (int loopback10000)

Also once the tunnel is up I could also see there's static route towards the client side via virtual-access interface and also static route on client side. I have already configure SPLIT ACL on server side allowing the required network access.Attached is the configuration of both server and client with all required show output.

Cisco Firewall :: ASA 5505 8.4.4 Stops Using EzVPN After Configuration

I've got some ASA5505 which run as EzVPN clients in NEM, connecting to a ASA5510 as head-end. The ASAs are configured with a CSM and AUS. But whenever they are getting a new configuration through the AUS they stop trying to establish an EzVPN connection to the head-end. After a "reload" they run with the new configuration and establish the tunnel as expected.

Cisco VPN :: 2911 Remote Office With Dual ISP And EZVPN

Aug 9, 2011

I am attempting to get a solid setup for a remote office we have going up and I am running into little issues that I cant seem to get around.
 
Basically, we have a remote office that will have dual ISPs, one hard wired circuit from a local carrier and the other will be a Verizon 4G router that plugs in via Ethernet and hands out DHCP to my Cisco router.The Cisco router is a 2911 with IP SLA configured.  I have it setup to ping my DC out one interface and if that fails, it removes the default route and injects a new default route from the other ISP,
 
The problem I am having is with the VPN.  I figured using EZVPN would be the only solution because the Verizon 4G only supports DHCP so I have to be able to connect from a dynamic remote host.  The other caveat is that failover needs to be seamless as we have no person onsite that can troubleshoot.  Its fine if it takes a few minutes, but the VPN just needs to come back up on its own without any intervention.
 
I attempted to setup two different EZVPN crypto maps on the router but realized you can only have one inside cryptomap per interface, which would cause a problem with the internal network.  I thought I could just create subinterfaces off the router to have two inside interfaces to work with but that wouldnt have supported because they would now be on different subnets.
 
I decided that adding an ASA5505 behind the router may be the simplest solution.  Use the router only for the purpose of handling routing between the two ISPs and performing NAT out the interfaces.  Then use the ASA to do EZVPN from.  This works well but there are some issues I am trying to work through.
 
First, when the ISP fails over to the backup, the NAT translations have to timeout before things start working again.  For a constant ping, this is fine, I have the timers set down to 15 seconds for NAT timeouts and after 15 seconds the ping picks right back up again.  However, this breaks the EZVPN.  The ASA keeps trying to bring up the ISAKMP nearly every second, which keeps resetting the countdown on the NAT timeout for the remote EZVPN server.  Because of this, the VPN will never come up until I manually clear the NAT translations on the router.  So my first question is this; is there a way to adjust the timer that the VPN uses to try to bring the tunnel up?  I tried the crypto isakmp keepalive command but that didnt work, it looks like it doesnt work with EZVPN.
 
The second issue is really with the IP SLA and is only an issue because of the first issue I mentioned.  When the router first comes up after a reboot, both the primary and secondary interfaces come up.  However, since the primary default route is only injected into the routing table once IP SLA is up and can reach its destination, the secondary route gets injected initially and the VPN comes up over the secondary ISP.  In a few seconds, the primary default route is injected, changes the path and because of the NAT translation, breaks the tunnel and never comes up again because of the first issue with the VPN tunnel renewing the NAT translation continuously. 
 
I could easily go out and purchase a $100 Linksys router that will do the failover and clear its NATs and everything, but I need better reliability out of the hardware than that.  There has got to be a way to do this on a Cisco device since consumer level equipment can.

Cisco VPN :: 2800 - EzVPN And DmVPN On Same Router / Interface

Jan 20, 2012

I have setup DMVPN and EAZYVPN on  one router. Tunnel interface on Spoke one and Spoke two are up/up and show crypto ISakmp sa shows both tunnels are in idle. However, tunnel to Spoke one(10.10.1.1) keep bouncing on and off(see below). Every 30 sec or so, the tunnel gone back to IKE phase while tunnel for spoke two(5.5.5.1) still leave active. THe configuration on the HUB side is the same for both spoke!! show crypto ipsec sec shows both side has the same life time(IOS default). Could that be an IOS debug on the spoke one?
 
Hub :

Cisco Firewall :: ASA5510 - Routing From EzVPN Client To Non-LAN Zone

Feb 24, 2013

I got a Problem with Routing on a ASA5510.
 
I have ezVPN Clients connected to the ASA5510. Those Clients are assigned an IP from 192.168.236.0/24 Pool.
 
I have a Router of a contractor connected to a dedicated ASA Interface called IBIZA with IP Net 10.100.10.0/24 and the Router itself with the IP 10.100.10.1. Behind that Router is another private Network which I need to reach from the ezVPN Clients.
 
The Connection from the ezVPN Clients to the "LAN" Interface/Network on the ASA works fine, but I cannot reach either the Contractor Router (10.100.10.1) nor the Network behind that.
 
From the LAN Network (on the LAN Interface) I can reach both the Contractor Router and the Network behind.
 
When I use the Packet Tracer Tool from the ASDM it tells me that the Traffic goes through but ends on the LAN Interface. But it should end on the IBIZA Interface or am I wrong here ?
 
What do I need to tell the ASA to route the Traffic from the ezVPN Client to the Contractor Router and back ? I have set up the ezVPN Connection as full-tunnel so all Traffic goes through the VPN Tunnel. That shouldn´t be the Problem.

Cisco VPN :: Does ASA5505 EzVPN Support Reactive Primary Vpn Server Feature

Nov 24, 2011

i am going to configure asa5505 as the azvpn client . and configre primay and secondary vpn server in the list.i find some feature that is support by ios ROUTER  ezvpn, not sure it will be support on ASA ezVPN???
 
will the ezvpn   fall back to the primary vpn server , if primary back on line,  on ASA? The Reactivate Primary Peer feature allows a default primary peer to be defined. The default primary peer (a server) is one that is considered better than other peers for reasons such as lower cost, shorter distance, or more bandwidth. With this feature configured, if Easy VPN fails over during Phase 1 SA negotiations from the primary peer to the next peer in its backup list, and if the primary peer is again available, the connections with the backup peer are torn down and the connection is again made with the primary peer.

Cisco :: Test Fast Roaming Using A Cisco 2100 Series Controller And 2 1140 APs?

I'm trying to test fast roaming using a Cisco 2100 Series controller and 2 1140 APs. The initial authentication succeeds fine and the wireless connection works ok using WPA2+CCKM and LEAP with a Cisco ACS radius server.The problem is that the client does not attempt to preauthenticate with the other AP because the RSN Capabilities IE in the AP beacons and probe responses do not set the RSN Preauthentication capable bit. I can't figure out what it takes to get the APs to indicate to clients that it can do preauthentication. I'm been crawling through all the documentation I can find, to no avail.

Cisco :: IPSec Tunnel Between Cisco ASA And OpenBSD (Access Enforcer)?

I currently use a device called the Access Enforcer which runs OpenBSD. I have 3 stable, working VPN tunnel's where the other side's device is a Cisco ASA 5520 or 5540. I was setting up my 4th VPN where the other side used a Cisco ASA 5520 and ran into issue's. The Cisco side can bring up the tunnel. Once the tunnel is up each side can talk to the other side. However, when the tunnel is dropped, the OpenBSD side cannot bring up the tunnel. The error received is on the OpenBSD device is "isakmpd[29581]: transport_send_messages: giving up on exchange from-XX.X.X.0/24-to-XX.XXX.XXX.240, no response from peer XX.XX.XXX.141:4500".

Cisco Switching/Routing :: Cisco 3750G Error During POST

Dec 5, 2011

I am trying to configure a 3750G that has been sitting on the shelf for several months and am getting the following error -
 
% Error: Unable to create flash:/microcode_update% Error: It must not already exist

Normally, getting an error during POST isnt a good thing.  My first thought was that flash was corrupted or flagged RO somehow. I did fsck flash: with no change.  I next tried fsck /test flash:.   It tested 77 blocks and performed 0 erasures.  It had been running for about 15 minutes with no problems reported so far.  Multiple reboots of the switch still report the same error.
 
I have reviewed the history of what I have done on this switch and finally think I found the problem.  I noticed a microcode_update directory that I am not used to see on a 3750.  Deleted the directory using the rmdir command and rebooted the switch.  On reboot, I noticed that a front_end/ directory was listed as being created as well as fe_type_1 and fe_type_2 were created.  The switch now boots up without any errors.
