Cisco VPN :: ASA5515 - Failover To Different Tunnels With One ISP
Sep 10, 2012
I have an ASA5515 and our remote sites which have a mesh topology of VPN. At some times of the day router to particular links are down do to the ISP core, but the tunnels from the same firewall can communicate to other sites. Is it possible to have a way where you could route traffic to another ASA which has a connection to both the ASA which want to communicate and have the traffic hairpinned, I know this is possible but is it possible to make this automated.

I want to assign multiple IP addresses for VPN service on same physical interface. But ASA don't support secondary address,loopback interface.So, I tried to use IP addresses assigned on another reserved interface ,but VPN connection could not be established.Thats,s why I want to assign multiple VPN addresses,I want to move and add old ASA's VPN's IP address to new ASA located at DataCenter.

I 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.

Could I get a validation that this config is correct in that it allows inbound access to the web server and that I should be able to ping it from my inside interface.
I tried to use the example code from Cisco DocID: 115904 for DMZ WebServer, but I found the object NAT parts did not work with my 8.6 IOS so I modified them as shown in my config.Example from 115904 doc.
!!!!
object network WebServerPublic
host 24.25.26.80
object network WebServerPrivate
host 192.168.1.80
nat(dmz,outside) static WebServerPublic service tcp www www ---> this does not code
!!!!
With the below code I do not get a ping reply sourcing from a 10.1.0.X host to 192.168.1.80 web server.And I cannot browse in from the outside to it either.I do see the MAC for 192.168.1.80 in the ASA's arp cache for the dmz interface.The web server is on a VMware ESX environment and I'm not sure it is set up correctly.
!
ASA Version 8.6(1)2

I am setting up an ASA5515 to replace an existing Linux based firewall. Unfortunately the ASA5515 does not support source based routing.I have two internet connections currently used for specific connections - the second connection is NOT a failover connection.I have the default route to Internet connection 1.I want to route smtp out the second Internet connection.The routers connecting to the internet are a 877 and an 878The options I am considering is a layer 3 switch between the firewall and the routers to enable source based routing or replacing the 2 routers with a single router and the appropriate wic interfaces.

After pulling a brand new ASA5515 out of the box this morning, I spent countless hours scratching my head wondering why:
1. I cannot establish an HTTPS connection to the Management port - https://192.168.1.1/admin
2. When connecting via the console port I get prompted with a username and password sequence that I don't know
I get an SSL Version Error message when I try to connect with any browser. although I did find a way to resolve it, it requires a console port connection which is not working either.This is not my typical experience with the console or ASDM port setup.

I set up a full mesh LAN-to-LAN VPN for a client with 4 sites. Each site has an ASA 5505 running 8.2(5). Site-to-site VoIP traffic runs in the VPN tunnels, as well as traffic to/from a file-server located at the main site. There are two back-up servers, one at the main site and one at a remote site. The main site has 2 bonded T1s and the other three sites have a single T1. How should I go about setting up my QoS?
My top requirement is that VoIP traffic will never be pushed out of the way for data traffic. My secondary consideration is to give more preference to file-server traffic than to web traffic and to make back-up traffic the least important. I'm currently researching to see if the VoIP provider is DSCP marking EF on the VoIP traffic, but I am going to assume they are for now. I know the IP of the file-server and back-up servers.

VPN Tunnels Monitoring on ASA5510 with IOS 7.0 (Monitoring through Nagios Server).I want to use Nagios to monitor each of the S2S Tunnels built on ASA 5510. I can use the icmp on Nagios by adding Nagios host in IPSEC network of each tunnel but in that case the change needs to be done at other end of Tunnel as well.

I have a Cisco 1921 and it has 2 VPN IP-sec site-to-site tunnels up and running. Lets say the tunnels goes from the Cisco to Site A and Site B.
Now i want Site A to reach Site B through the existing tunnels. I'm guessing that static routes maybe the answer but i cant seem to get it working.
The LAN networks is as follows:
Cisco: 192.168.15.0/24Site A: 192.168.0.0/24Site B: 10.27.27.0/24
At Site A i have set up a static route as follows:
Traffic destined for 10.27.27.0/24 Go to gateway 192.168.15.1 (the default gateway of Cisco LAN)
At Site B i have set up a static route as follows:
Traffic destined for 192.168.0.0/24 Go to gateway 192.168.15.1 (the default gateway of Cisco LAN)

We have multiple sites that have either fiber 20mb d/u or cable 50/10 d/u. Recently we have upgraded our head end router to a 2921 security based router and noticed that no matter if we are sending or receiving the most we can push is 1.6Mb. I would expect this number to be at least 8Mb for uploading and at least 18mb for downloading from other sites.I have included parts of my config and screen shots of bandwidth usage for troubleshooting.

I am having an issue where the GRE tunnels are up/up but are not pingable. The GRE tunnels are on a cisco 1811 and cisco 2811 routers The tunnel source and destination IP addresses are private addresses. These private addresses are pingable to each other and they are connected via IPSEC. The IPSEC tunnels are generated from the ASA to which the cisco routers connect. Probably the tunnels are up/up because keepalives are not configured. But I am still not able to see why I cnt ping the end points. The ACL for IPSEC in ASA includes the "permit gre host <Private IP 1> hist <Private IP 2>" commands.

I have 3 tunnels established (full mesh) with 3 CISCO ASA (all security+), through Internet : - Site A : ASA5510 - Site B&C : ASA5505, There is no main site or client site, each site has more than one network behind it. So I'd like to setup OSPF between all the ASA for them to exchange their route within the tunnel. I thought this was automatic when establishing the tunnel, but it isn't.

My current set up is 1 HQ router (2911 ISR) and 8 site offices with a non-Cisco router.Each site has an IPSEC tunnel back to the HQ router.All of the site routers have a dynamic external IP address.This set up has worked ok for now, but I would like to look at moving to GRE tunnels so traffic from the sites can be routed to each over.I have read up on the configuration and I can set up an IPSEC GRE Tunnel in test labs using a static IP address on the spokes however I have not been able to find any documentation on how to configure the HQ router to allow the tunnels from any IP address.I did try setting the tunnel destination to 0.0.0.0 on the HQ side but this does not work.

I am a employed at a credit union with 17 branches. We have a mpls circuit connecting the branches to our main office. I setup DSL as a backup connection. I have 17 RV042 Cisco VPN Routers. I created a secure vpn tunnel for every branch to the main office. I made a delayed route in our main router to fail over to the VPN, in case the mpls failed. Almost everything works great except our ATM's are required to connect to a router at our main office to a different subnet than the tunnel is connecting, therefore not routing through the tunnel. I've tried creating another tunnel but only works with one of the branches, cause I get a conflict at the main office when I try a second tunnel with the same ip network. Also I tried routing all the traffic through the vpn by putting in the address 0.0.0.0 subnet 0.0.0.0, at the branch site. But I can only do that for one branch, The Downtown Cisco won’t let me create another tunnel with that setting.

I have been tasked by my boss of finding out and implementing a solution of building GRE tunnels from 2 4408 Wireless controllers system for a guest wireless network. I am but a low CCNA wireless, working on getting motivated for CCNP wireless, but I didn't even know if this was possible and if it was where to begin. I have been reading configuration guides but figure I should ask the wireless experts of the world of Cisco.

I'm trying to monitor Tunnels activity. We want to gather statistics like bandwidth utilization per Tunnel and in the case of Remote Access also the user name associated with a tunnel. All this via SNMP
I've browse through the Cisco-IPSec-Flow MIB and found the TunnelTable, this seems to provide everything I need in Regards to Tunnels, I just need a tip in how to calculate or obtain the bytes Tx and Rx. I can obtain packets and Octets amounts but not actual bytes. Is there another OID I should be inquiring?
In regard to Remote Access I found the CRASSessionTable From here I can obtain the Group associated with the tunnel and I should be able to obtain the User name through the 1.3.6.1.4.1.9.9.392.1.3.21.1.1 OID, but I'm getting an UnSupported response when querying this particular OID.
What OID can provide the User name?
I know that Cisco Performance Monitor can in fact obtain all that info from the ASA so there must be an appropriate OID I can query to obtain this particular info.

I have an ASA 5510 running ver 8.0(2) that has (4) Ipsec tunnels going from it to various other locations. I am having an issue with data transfer speed on only one of the Tunnels. This tunnel is between the 5510 and the 5555, on that link I am getting a dat transfer rate of a little over 120k a second, whereas if I pull the same set of files from another location I am seeing a transfer rate of 5m per second.
I have verified that it is not a capacity issue on the Internet bandwidth on both locations, and I can pull the same data from the same location to various other locations via Ipsec tunnels, I am only having an issue with a specific tunnel going from the 5510 to the 5555.
Since it is not affecting other tunnels on the 5510 nor is it affecting tunnels on the 5555 going to other locations, I am leaning toward a routing issue within the ISP? I will say the ISP is taking me a long way around to stay in the same Metropolitan area.

We are planing on offering low end ASA 5505s as a customer offer to connect their network to our cloud as this is a business requirment. However, one of my colleagues is convinced that the license for the 5505 is *not* based ont he number of IPSEC endpoints, but the number of distince connections via *any* tunnel. So, according to him, if you have a license for 10 IPSEC endpoints, if you have 11 people connecting via *one* tunnel from a customer's network to our cloud, you go beyond your license.

I have an ASA 5510 at Site A with a L2L tunnel to another site, Site B. Single subnet at each site. In a few weeks we will be adding a second Internet connection to Site B, so both connections will be active. But we want traffic to go over the new connection unless it goes down, then use the other. How do I set that up on the ASA so it doesn't get confused as to which tunnel to take to get to the Site B subnet?
