I'm looking for automating a couple failover scenarios. Both VPN redundancy and black hole internet traffic redundancy.I currently use the more reliable T1 connection for the VPN connection and the DSL for internet traffic.My current configuration is working but requires a manual update to get the VPN or black hole back up and operational when either link fails.

I need to upgrade the active/standby failover pair of 5510 ASA's to have1 Gig DRAM each, and I am trying to plan out the upgrade process. I'm looking for a zero downtime upgrade process.
I know that the failover pair has to have the same amount of memory, so how do I perform a zero-downtime upgrade process?Can I power off the standby unit and upgrade it's memory first? Or will it cause a memory mismatch between the active and standby units when it is powered on?
I am having a hard time getting tunnel fail over working. My setup is illustrated below:
I derive my default route on the border routers. The 6513 peers with the 7206's using BGP to get the default route from each ISP into the core. On the core I use BGP weighting to get my primary default to point to ISP1. So far so good. When I look at my core I see to defaults with ISP1 preferred.
Each ASA has an IP Sec tunnel to the head end site configured (Not shown). The head end site has a crypto map entry with ISP1 and ISP2 defined (in that order) using the "set peer" command.
Fail over works great if an ISP drops the connection or my 7206 or ASA fails, but... While testing fail over I had an issue where both tunnels would be active and there were issues with traffic between sites. I could not determine the root cause. I can only guess that some traffic was going out one tunnel and when trying to come back across the other tunnel was dropped from the firewall because there was no connection built for it. After reading I found that in order to use multiple peers in the "set peer" statement, I needed to configure my head end as "originate-only". I have not done this yet as I have concerns. If the head end site is "originate-only" and the tunnel, for whatever reason drops, I cannot wait for interesting traffic at the head end site bound for this site to bring up the tunnel as most of the traffic originates at this site.
I have been reading about IKE keep alives and DPD but that doesn't sound like it will re-initiate the tunnel. Is this correct? If so I'm looking for a way to make this work.
I've two sites, the branch with an ASA 5505 and on the corporate office i've an ASA 5510.I need to make a easy vpn tunnel between this to sites and I've made some configuration, but for now, the ikev1 isn't working.
View 1 Replies View RelatedWe have to make disaster recovery site EasyVPN tunnels on Cisco 5505 ASA firewalls. Now there is only one main site and 3 remote sites.For DR we have to use the same subnet as it is on the main site because the Vmware virtual machines will be replicated to DR.For DR we are using Double Take software.What is the best solution for this? I think that we could use Destination NAT on ASAs. The other sites (HQ and remote) will se only the NAT address of theDR and not the real one which is the same as on the main site.We are using IPSec VPN? In packet-tracer on ASA I see that the packet is first NATed and then encrypted, so it should work, yes?
View 2 Replies View RelatedI just learned that the licensing structure for the ASAs is changing, but I don't have any details. We have roughly 30 ASAs (from 5505s to 5585s). If there's a licensing change, I need to do an impact assessment and plan accordingly.
View 5 Replies View Related We have a site with two inbound circuits, one for internet and one for our MPLS. Each circuit is being terminated by a 2921 Router and matching ASA 5510 Firewall. For the internal network, the Internet ASA's inside interface (172.16.0.1) is the default gateway for all hosts. OSPF is the routing protocol between all the routers and ASA's and routing is working. In fact, ICMP is working as well. From an inside host (172.16.0.81), we can ping anything on the MPLS network. But when I try to use telnet (for example), the connection fails. If I add a route to 10.10.10.0 to the host, or re-configure the host to point to the MPLS ASA (172.16.0.254) as it's default gateway, connections will establish.
Both ASAs are running 8.4(3), and have the following commands:
same-security-traffic permit intra-interface
interface Ethernet0/0
nameif outside

And from the MPLS nodes, I can see a tcp request is made.
I'm trying to configure policing and/or shaping on a setup of 2 x ASA 5505 Sec Plus. The units are placed in office A and office B and each have a ISP connection to the internet and a leased line with a capacity of 4/4 Mbit/s for interoffice communication.
On each ASA there's four subnets. VLAN 200 is used to connect the offices through the leased line.
Subnets:
Outside = 2
Data = 10
Voice = 100
Linknet = 200
I've read a lot of articles and posts about shaping and policing on the ASA but still can't get it to work like I wan't to. I'm trying to limit all traffic besides IP-telephony traffic to 3 Mbit/s and thus reserving 900 Kbit/s for voice traffic. I tried setting a service-policy on the linknet interface on each ASA and set Traffic match to Any traffic and QoS settings for both input and output.
I can see traffic passing the policy when I run the "show service-policy police" command but it never seems to be high enough to be policed which is strange since the ASDM monitoring shows that I'm pushing 3900 kbit/s. I file transfers verifies that policing does'nt work.
I'm setting up a Site-to-Site Cisco VPN between ASAs. I'm being told by the remote site engineer to set the maximum MTU at 1362. Is it possible to set the MTU for one specific site-to-site VPN on my ASA 5510 Security Plus to MTU 1362? I see my interfeces are all set at 1500. If not, would you recommend I setup a subinterface on my inside network router and a subinterface on the ASA with an MTU of 1362 to get around this issue? Then use this subinterface for traffic from my inside network to transverse through prior to hitting the VPN.

View 5 Replies View RelatedOngoing problem I have been having regarding a l2l VPN connection between our ASA 5510 and a client's ASA 5505. The client's main ISP is Comcast and he uses a secondary AT&T internet connection as a failover. When Comcast goes down, AT&T comes up and everything works great...except for the VPN to our ASA5510. I have not been able to get the VPN connection to work on the failover network. I have set up a separate, "Backup_WAN", interface in the firewall for AT&T. All of the same rules are in place for AT&T as there are for the primary Comcast connection (the VPN for Comcast works just fine) but I still cannot get the VPN to work with the failover.
Why the VPN would not be working?
We have two sites connected by a gigaman line. Routing between the two sites is done with a couple of HP routers. We also have two separate Internet connections, one at each site, through different providers. The border firewall at one site is a Cisco 5505 and at the other site it is a Cisco 5510. If the gigaman line goes down, we would like to fail over to a site-to-site VPN. Any clue how to set this up? We can set up the site-to-site VPN. how to make it serve as a failover. Another question is whether the VPN will cause confusion when the gigaman is operational.
View 11 Replies View RelatedWe have two offices in the US and one in Mexico. Our site in Mexico connects to our headquarters in the US over an AVPN/ MPLS circuit .Mexico has a separate Internet connection through TelMex. There is an ASA 5510 at headquarters and an ASA 5505 in Mexico. We have a fail over VPN set up in the ASAs for times when the MPLS circuit goes down. All Internet traffic in Mexico is supposed to be routed to the TelMex connection. All company traffic is supposed to be routed to the Cisco router. ASA is supposed to be last resort route. We have a fail over VPN set up in the ASAs for times when the MPLS circuit goes down. (Or at least we did until I had someone work on the configuration) Everything had been working fine for the last 4 years.
Yesterday when the MPLS went down, so did their Internet connection. I realized the Internet traffic is now coming through the MPLs circuit to head quarters and out our ASA. Obviously there is a problem with the configuration. I do not have enough experience to figure this out. I have attached the configs and the routes for both the ASA and the router.
Configured ASA 5510 ISP failover and working fine.My ASA as configured as DHCP server also. So its serves IP addressing details including mask,default-gateway, DNS server IPs.Here my issue is whenever my ISP failover occurs my ASA sends previous ISP DNS server IPs to my inside clients.
Here i like to configure my ASA to serve IP addresses dynamically.Or is there any global DNS IP addresses which will work for all ISPs?
I need to configure one interface in failover because the client has 2 ISP.[CODE]
View 2 Replies View RelatedI have a ASA 5505 which is connected to a remote site which also has a ASA 5505 over a L2L VPN tunel. One of the sites has a WAN failover configured with two ISP which is working successfully.
But, when the WAN connection fails over to the backup connection the VPN link breaks as the peer site IP address has changed and the VPN can not establish a connection.
Would it be possible to configure a VPN failover so that when the connection failovers so will the VPN tunnel?
There are 2x Cisco ASA 5505 in an active/standby failover config. The primary asa 5505 has been reset and the secondary is now running as active. I would like to reintroduce the primary again but need to know how to do this.
Ideally I would like to remove the failover config and start from scratch. Do I just need to enter the following to disable failover on the active secondary box?
no failover
no failover lan unit secondary
no failover lan interface failover Vlan999
no failover interface ip failover 192.168.254.1 255.255.255.252 standby 192.168.254.2
So we currently have a T1 connection at our location. We were looking to add a high speed cable internet and add an ASA 5505 with Security plus license to do failover between the two. I have found a few examples on how this would work but curious about a couple things.
We would want the Cable to be the primary, T1 as a backup.Currently the IAD that handles our T1 does dhcp, dns, and NAT.. Who/what would handle these items with the setup above?
Can I run Cisco ASA failover with dual ISP run active/standby configuration and SLA monitor to monitor the primary ISP gateway and failover to the secondary gateway but not failover to the failover firewall unless an actual event occurred that required a ASA failover?
View 3 Replies View RelatedI 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 have a customer with two ASA 5510s. All four ports are used by the following interfaces: inside, outside, dmz, and failover. This customer is looking at getting redundant internet connections, but we don't have any ports to the redundant connection. What I'd like to know is it possible to configure sub interfaces on one of the currently occupied ports (I'm thinking inside) and use one for inside and one for failover. This way I could have the other port free for the redundant internet connection.

We are going to buy a new Firewall ASA5510 to use failover possibilities.I just need to be sure it will be possible to implement as I have the following output after a "show ver" command: Cisco Adaptive Security Appliance Software Version 8.3(1) [code]
As you can see the failover line is set as "Disabled perpetual".We are actually using base license as i have not been able to find any contact for CISCO to get official support or new license.
I have a customer who has purchased a Cisco 5510 and after we received it and all the necessary VPN, 3DES etc. licensing for it, then informed us that they order 2 T1 lines so they can have Internet failover.
My question is: Does this require an additional specialized license from Cisco in order to enable and configure it? And if so, what that part number is?
How to design a network setup and achieve failover in the below scenario.
(Vendor router)
L3-Switch ---- ASA FW1 ---switch-- Router 1 ------ MPLS cloud1 ----- Router A ------------ L3 switch
(Vendor router)
L3-Switch ---- ASA FW2 ---switch-- Router 2------ MPLS cloud2 ----- Router B------------ L3 switch
I am planning to achieve the failover either of the following ways -
1) Configuring both ASA FW as active/standby method .
2) configuring ASA FW 1 tracking command pointing to the ISP end ip address so the traffic would be moved to secondary firewall by putting a AD as 1 on ASA FW ......pointing to the ISP ip address and other floating route ( with a higher AD value) to the secondary firewall interface.
3) To configure HSRP between the Routers.

View 2 Replies View RelatedI have two sites that each have asa 5505's and each have dual ISP's. Currently I'm using sla monitor to failover to the secondary line when there is a detected outage. After this sla failover occurs which seems to be instant, secondary ISP re-establishes the VPN. This process takes about 30 seconds. My thought is that the side which is healthy does not detect the outage due to a preset amount of timeouts and thats where this 30 second delay comes in to re-negotiate the VPN tunnel. can I create a smaller window of time to heartbeat between the two so that the VPN outagage is detected in around 5-10

View 1 Replies View RelatedI have a question regarding failover monitoring on the ASA5505 in an active/standby configuration.
I understand that on the 5505 you create VLAN interfaces and then assign the VLANs to the 5505 switchports. With failover configured on the 5505, the VLAN interface names are monitored. For example, VLAN 100 interface named Inside is assigned to ethernet0/1, switchport mode access. When issuing a show failover command the output will show the monitor status of interface Inside..
Does failover monitor the VLAN virtual interface only? Does failover also monitor the link status of the ethernet0/1 switchport?
Currently I have a network that looks like this:
ASA5510 - - - Internet - - - ASA5510

The MPLS connection is currently down, I'm trying to run a failover Site-to-Site VPN over the internet. All of the examples I've read have both connections involved in the failover coming out of one device. Since I'm not working that way, what is going to be the best way to failover? Do I need to set up some sort of IP SLA in the config? Or can I somehow weight routes in EIGRP in a way that the connection will failover from Internet to MPLS when the MPLS goes down and vice versa when the MPLS connection comes back up?
i read that you need only one L-ASA5510-SEC-PL for setting up a Active/Standby Failover. I installed the license on the 1st ASA and tried to setup the failover via the ASDM wizard. It always fails, because the 2nd device can't have a 'base' license.So does this mean, i really need another license?
View 5 Replies View RelatedI have two ASA 5510, The one which I just got shows the CPU speed to be 1599MHz While the previous device (which is also 5510) reads the CPU as 1600 MHz.According to Cisco, for Failover redundant configuration, both devices must have same hardware configuration. Technically, this slight difference should not be an issue but I need to confirm that thess devices will work fine with failover configuration.
