My Location CanadaI would like to connect to separate VPN’s located in England which connect to servers located outside of the UK.I would like to set the 2nd VPN as a failover.If 2nd VPN fails I would like the connection to break and not failover to my Canada connection.
View 4 RepliesCurrently, my customer has 2 units of Cisco PIX 515E running on Active/Standby mode. As for the heartbeat link, there are 2 dedicated switches placed in between both the Cisco PIX 515E i.e. FW1 --> SW1 --> SW2 --> FW2.
My customer will be changing both the Cisco PIX 515E to Cisco ASA 5510. Now, they are asking me, since they will be using Cisco ASA 5510 eventually, can the heartbeat link be a direct UTP cross cable or must the 2 switches in between still exist?
I remember I have tested this before, few years back, in the event I were to pull out the UTP cross cable that's connecting both the Cisco ASA 5510 Firewalls directly (without any switches in between), the Active/Standby mode still works fine. It doesn't go bad whereby both the Cisco ASA 5510 suddenly becomes Active/Active, and causes network issue.
Are switches required for the heartbeat link in a Cisco ASA environment or can a direct UTP cross cable connection be adequate.
We have 3 sites, with a Cisco ASA 5520 at each location.
HQ (Headquarters) internal network: 172.16.110.0/24,
DR (Disaster Recovery) internal network: 172.16.120.0/24
BO (Branch Office) internal network: 172.16.150.0/24
HQ and DR have a 100Mbps permanent MPLS link between each other.Branch Office has a Site 2 Site VPN connection to HQ. If it fails, it establishes a Site 2 Site VPN connection to DR. This works perfectly.Now the routing issue... There is no route to the BO in the routing table at HQ/DR. The default gateway is used to reach the BO and that works for HQ when the VPN is between HQ/BO. If the VPN fails over to DR/BO, HQ can't reach BO anymore.I need to have some kind of conditional route injection from the ASA where the VPN is established. I was considering a tracked static route, but I was wondering if the S2S VPN itself has a functionality to do so. I thought the Reverse Route Injection was it but it's enabled on our crypto map and doesn't seem to work...
Does anyone know if it's possible to use a single interface on the ASA for both the failover interface and for stateful failover? Here's my situation.I'm looking to provision a pair of ASAs and I want to do stateful failover.The problem is that I need four interfaces (inside, outside, and two physical DMZ interfaces).I'm looking at either the 5520s or 5540s and these boxes need to run the IDS SSMs, so I can't use the 4-port expansion SSM.
I want to do stateful failover so I need two failover interfaces.What I'm wondering is if I can take one physical interface,run two subinterfaces on it, and then use those two subinterfaces for my failover and stateful failover interfaces.That would leave me with the four interfaces that I need for everything else
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.

Ongoing 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?

View 1 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.
a customer have 2 pix 525 with ver 7.0.1 in a failover configuration with serial cable and 2 sc fiber interface and 2 fastethernet 1 used for failover. the strange behaviour is that when i try to do traffic from inside to dmz or dmz to inside the maximum transfer is 862Kb/s to 1MB/s not more.... i don't understand what's happened. the show mem and show cpu are normal 7% mem used and 1-2% cpu used. attached you will find the configuration.
View 5 Replies View RelatedIs it possible to setup 2 x Cisco ASA 5520 that are in an Active/Standby failover using sla monitoring?
For example ASA1 outside interface connects to an upstream switch and you setup sla monitor with icmp echo to ping that switch. The switch goes down and you need the other ASA2 to become the Active ASA. Can the sla monitor be automatically integrated with the failover commands for this to happen?
Overview Firewall is ASA 5510 running 8.4(9)Core network at Head Office uses OSPFStatic routes on ASA are redistributed into OSPFStatic routes on ASA for VPN are redistributed into OSPF with Metric of 130 so redistributed BGP routes are preferredCore network has a static route of 10.0.0.0/8 to Corporate WAN, which is redistributed into OSPFBranch Office WAN uses BGP - Routes are redistributed into OSPFThe routers at the Branch Office use VRRP for IP redundancy for the local clients default gateway.Primary Branch Office router will pass off VRRP IP to backup router when the WAN interface is downBackup BO router (.253) only contains a default route to internetUnder normal operation, traffic to/from BO uses Local Branch Office WANIf local BO WAN link fails, traffic to/from BO uses IPSec VPN across public internet I'm trying to configure dynamic routing on our network for when a branch office fails over to the IPsec VPN. What I would like to happen (not sure if it's possible) is for the ASA to advertise the subnet at the remote end of the VPN back into OSPF at the Head Office.
I've managed to get this to work using RRI, but for some reason the VPN stays up all the time when we're not in a failover scenario. This causes the ASA to add the remote subnet into it's routing table as a Static route, and not use the route advertised from OSPF from the core network. This prevents clients at the BO from accessing the Internet. If I remove the RRI setting on the VPN, the ASA learns the route to the subnet via the BO WAN - normal operation is resumed.I have configured the metric of the static routes that get redistributed into OSPF by the ASA to be higher than 110. This is so that the routes redistributed by BGP from the BO WAN into OSPF, are preferred. The idea being, that when the WAN link is available again, the routing changes automatically and the site fails back to the BO WAN.
I 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?
I have 2 Cisco routers 3945. Use HSRP for links failover. Does exist any possibility (any protocol) which makes routers configuration's automatic synchronization (as failover for ASA firewalls)?

I've got a setup where we have a wireless connection coming in and using mikrotik router. We have multiple stores coming in via the wireless with a dmvpn.
The vpn's terminate on the cisco c870 and can be seen when running: show dmvpn.The cisco has a default route to the fibre router (10.0.0.252). The wireless router is the default gateway for the network. The failover from wireless to adsl fails. (due to the cisco routing traffic back to the wireless router when wireless fails)
If I change the default route on the cisco to dialer1, the failover works, but none of the vpn's connect. The Branches all have dynamic ip addresses. The HO has a static ip.
My goal: I want to achieve adsl failover for when the wireless goes down and still have the vpn's connected.
Can I have some sort of "Dynamic" route on the cisco. So when the vpn traffic comes in via wireless and hits the cisco, the vpn traffic can then go back out that way via the wireless router, but still have a default gateway on the dialer interface for failover?
