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?

I have two ASA 5510's that I want to setup in a Active/Standby configuration. My only question is on how to connect the inside ports to my LAN. I have 5 Catalyst 3750's stacked together that connect to the ASA's. Should I run the inside interface on ASA1 to a port on switch 1. Then run the inside interface on ASA2 to a port on switch2? And make sure both those ports are in the same VLAN? But, then when failover occured, how to I automatically make it clear the arp cache so the traffic starts flowing out of the right port?
View 1 Replies View RelatedI just upgraded an ASA-5510 from 7.0 to 8.4.4-1 and theres a lot of stuff in it I don't recognize that I never added, mostly because of new network objects, nat commands, and other migration stuff. Its been awhile since I've configured the ASA and I think I'd like to start from scratch and clean it up a bit because theres so many lines for so little that I really need.
I have a 5510 assigned an IP address on the outside interface with 3 inside interfaces and below are the only requirements I need.
Network-A (192.168.1.0/24)
- incoming ssh port 2202 goes to node 192.168.1.2
- incoming ssh port 2203 goes to node 192.168.1.3
- handle incoming https (443) requests
- handle incoming www (80) requests
- cannot see Network-B or Network-C
Network-B (10.0.0.0/16)
- ssh to nodes on Network-A
- incoming ssh port 22 goes to node 10.0.0.20
Network-C (192.168.2.0/24)
- ssh to nodes on Network-A
- incoming ssh port 2210 goes to node 192.168.2.2
ASA-5510
- sends logging to syslog node 192.168.1.3 on Network-A
- there are DNS and NTP servers located outside
Need configuring Client to Site IP Sec VPN with Hairpin on Cisco ASA5510 - 8.2(1).
The following is the Layout:
There are two Leased Lines for Internet access - 1.1.1.1 & 2.2.2.2, the latter being the Standard Default route, the former one is for backup.
I have been able to configure Client to Site IP Sec VPN
1) With access from Outside to only the Internal Network (172.16.0.0/24) behind the asa
2) With Split tunnel with simultaneous assess to internal LAN and Outside Internet.
But I have not been able to make traditional Hairpin model work in this scenario.
Following is the Running-Cong with Normal Client to Site IP Sec VPN configured with No internal Access:
LIMITATION: Can't Boot into any other ios image for some unavoidable reason, must use 8.2(1)
running-conf --- Working normal Client to Site VPN without internet access/split tunnel:
ASA Version 8.2(1)
!
hostname ciscoasa
[ code ].......
Neither Adding dynamic NAT for 192.168.150.0/24 on outside interface works, nor does the sysopt connection permit-vpn works
What needs to be done here, to hairpin all the traffic to internet coming from VPN Clients. That is I need clients connected via VPN tunnel, when connected to internet, should have their IP's Nattered against the internet2-outside interface address 2.2.2.2, as it happens for the Campus Clients (172.16.0.0/16).
I have a old server that has custom apps developed by a bankrupt company that we can't replace yet. We are being tasked with upgrading the Operating System and security patches, while preserving the existing live server. I was able to accomplish this by virtualizing it, then cloning the virtual machine. Where I got stuck was, the custom app requires a specific host name. So, I got the idea to have the two servers live on different sides of the firewall until the test platform is accepted and the old live one can be retired.
My problem is that I have no experience with configuring a real firewall like this asa5510.
Servers are:
CM1 live server
CM2 test platform
ADS Active Directory and File and Print

I've started to carefully poke around in the Cisco ASDM-IDM, but haven't figured out how to access the DMZ from the outside (so far just testing with http as I don't have my certificate to setup https just yet). Am I missing something to get through to the DMZ from the WAN side?

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.

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.
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.
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?
