I think they will support ezvpn, just need confirm .
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.
I have and office that the cable modem tends to go down on the weekend. Can i setup my asa to support a second provider so that if the one connection is slow for some reason, my users could connect to the second provider instead? they would both be used at the same time most the time.

View 1 Replies View RelatedI'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 ?
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?
View 3 Replies View RelatedI 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.

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.
View 2 Replies View RelatedOur 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.
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.
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 ?
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?
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.
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]
View 1 Replies View Related 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.
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.
View 1 Replies View RelatedI 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.
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?

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.
If you have a headsite with multiple EZVPN clients (PIX 501 & 515) connected in a star configuration can you have one remote site connect to another remote site using the intra-interface command and modifying the encryption domain on the EZVPN Server?

We are pulled the plug on our PIX 501 as its not letting us use all 100Mbit that our cable provider is now piping to us. I read the conversion guide but it made no mention of the 501's. Only the 515's or newer.The ASA5505 is putting up a little bit of a fight (This what I get for failing my CCNA??)After refusing to configure the LAN ip address to something other than what it was shipped with, I broke down and connected to the management console and forced an IP address on the LAN side. Now I reset my default config and everyone can get on the internet.Until the ISP cuts you off because you forgot to set your static IP. Oh, and by the way, they dont support Cisco gear.
When I attempt to assign the IP to the outside interface, it accepts without a hitch, but everything grinds to a halt. I cannot have this, as I have off-site users that operate with dedicated ports using Remote Desktop. I've attempted to set the IP via both ASDM and management console. I've tried setting a static route, but that doesnt give me any love either. Im running ASA Version 8.2(1) and ASDM Version 6.2(1)Once I get the static IP set and working properly, I can tackle moving the port configs.

I have also attached a Visio for this and the running configuration from the ASA and 3750. We don't have access to the TNS VPN router. Our responsibility is to just to make sure the tunnel comes up.
1) Create a static NAT on the ASA for Public to Private IP of the VPN router
Public - 208.64.1x.x5 / 28

Will the ASA automatically ARP for this address or do i have to configure another interface on the ASA with this public IP?
2) What would the access list look like on the ASA?
3) The client gave us some config to copy the stuff on the ASA so that they can create the tunnel but i couldn't put those commands in the ASA. How would this be applied and on what interface?
