Cisco WAN :: IPSec VPN Backup ASA5510

Jan 3, 2013

I have the need to configure a backup VPN, I have remote branches with cisco 800 routers that make a VPN to an ASA5510 in the main offices, but as a DRP I want to have a backup VPN to another site. I dont know if it is a failover configuration or backup VPN, how to start investigating.

Cisco Firewall :: ASA5510 Dual ISP And VPN On Backup

Dec 19, 2012

ASA5510 ios v8.4.I've setup dual ISPs and I'm trying to get ipsec VPN client access to work on the backup interface (outside-backup). The goal is to have outbound traffic on the inside subnet NAT'd through the main interface (outside) while inbound ipsec VPN clients connect and operate off of outside-backup.crypto map is applied to 'interface outside-backup,' however clients are unable to connect. If I switch the default route to go through outside-backup everything starts to work again.

Cisco Firewall :: ASA5510 With Dual ISPs And Static NAT On Backup

Dec 12, 2012

Looking to have an ASA5510 with two internet feeds. Moreover, I would like to have my static nat translations continue to work on the backup feed. I have outbound nat working, however I cannot get the inbound nat to work. I had this all figured out in 7.x but now with 8.x I cannot seem to get it working. If anyone has a 8.x example config.

Cisco VPN :: ASA5510 7.2 - GRE Over IPsec / ASA And NAT-T?

Nov 20, 2011

I want to establish GRE over IPsec tunnel between four branch offices and head office. At branch offices, I have 1841 router with Advanced Security software. At head office, I have a ASA5510 7.2 as frontend with one public IP addres and 1841 router behind it in private address space. Since ASA is not supporting GRE tunnels, can ASA be endpoint for GRE over IPsec? If not, can ASA pass this tunnel to the 1841 router behind it, so 1841 would be logical tunnel endpoint? What should I pay attention? Should both ASA and every 1841 support NAT-T, or just ASA?

Cisco VPN :: IPsec L2L VPN Between A ASA5510 And ASA5505

Jul 25, 2011

I have set up a IPsec L2L VPN between a ASA5510 and a ASA5505 which is working just fine.Every now and then our management station receives the following syslog message: Session disconnected. Session Type: IPsec, Duration: 2h:23m:23s, Bytes xmt: 3283338, Bytes rcv: 8637607, Reason: Phase 2 Error.I have already searched the forum for this message to exclude all the possible reasons for this message:
- the complete crypto maps are the same on both ends (lifetime, psk, pfs etc)

- the ACL's used in the crypto maps are exactly the opposite of each other

Cisco VPN :: 837 Router To ASA5510 IPsec VPN

Mar 19, 2012

I have a 5510 running 8.42 code with multiple site to site tunnels coming into it.  Sites vary from ASA 5505's, 1841 and 1921 routers which all work perfectly.  That being said I think the ASA side is good.  I have an 837 running 12.4 code, Cisco IOS Software, C837 Software (C837-K9O3SY6-M), Version 12.4(5b), I'm trying to configure it for site to site VPN back to the ASA.  When I ping from the E0 interface I get the following debug output and nothing else.  I've made a lot of changes to no avail in getting closer to a successful configuration. [code]

Cisco WAN :: ASA5510 Routing Through IPSEC Tunnel

May 20, 2013

I have an ASA5510 configuration that I'd like to add to.In this configuration there is a site to site IPSEC VPN tunnel to a remote location.It is tunneling a particular subnet for me and everything is working.In the remote subnet, there is an ASA 5525-x connected on the outside interface. Let's say for argument's sake, the outside IP is the Inside interface, i've configured network.The only static route I have configured on the 5510 is the default gateway that goes to the ISP.I assumed that I have to add: route Outside 1.I did this, but i'm not able to reach the destination network. I can't see anything hitting the 5525-x and the only thing I see on the 5510 is the building outbound ICMP and the teardown for the ICMP.

Cisco VPN :: ASA5510 - Latency Through IPsec Vpn Site Tunnel

I have an asa 5510 that has many(17)ipsec vpn site tunnels on it.  One of the tunnels, one running to a c1900isr at the other end, is experiencing 400 to 500ms latency through it.  It does appear to be the tunnel only because there is no latency to the internet.  I cleared the tunnel group out and readded it to no effect.  isp says everything fine.  any other known causes for this

Cisco VPN :: ASA5510 - Slow Traffic On IPSec Tunnels

May 2, 2013

We have many VPN tunnels back to our corporate office.  All of these tunnels are very slow (same with our client VPN's).  Our main firewall device at the corporate office is an ASA5510.  We have a 100 Mb/sec Metro Ethernet internet connection here.  We do not allow split-tunneling.

Our remote sites vary.  We have DSL connections, cable internet connections, and other types of broadband that vary in speeds from 5 to 100 Mb/sec (up and down).  The remote sites mostly have PIX 501's, but we have an ASA 5505 in one of the locations.

To take an example.  On one of our remote sites that has a 100 Mb/sec connection, if I ping device to device, I'm getting ping times of about 50ms.  And I'm pinging back through another 100 Mb/sec connection.  If I get on a computer down there and run a speed test, I'm showing down speeds of about 1.5 Mb/sec... nowhere near 100.  Some of that could be due to the lack of split tunneling, but I also suspect this could be an MTU issue. 

Right now, all my MTU's are just set to the default 1500.  Perhaps this is too high.  I used this site to check my max: [URL]
I did a few tests from behind several of my firewalls.  I pinged from a machine on one side of the tunnel to the firewall on the other end.  I'm assuming the max MTU I come up with is the max MTU for the firewall I'm behind while pinging, right?  The max amounts I came up with for some of my devices were as follows: Corporate ASA 5510 > 1272 (if you add the 28 byte packet header that would make it 1300) Remote PIX 501 > 1416 (if you add the 28 byte packet header that would make it 1444) Remote ASA 5505 > 1418 (if you add the 28 byte packet header that would make it 1446)

So, do I just need to set my MTU values to the appropriate amounts?  I have tried changing the value, but I don't see any change in speed/performance.  But I also don't know if I need to reboot the firewalls after changing the MTU.  I know with Catalyst switches, you have to reload.  But I didn't see any messages about needing to reboot on the ASA's/PIX's.

Cisco VPN :: ASA5510 Easy VPN Remote / IPsec Session Count

Feb 21, 2013

I recently upgraded our head end ASA5510 at our datacenter from 8.2.1 to 8.4.5. The ASDM was also upgraded from 6.2.1 to 7.1.(1)52. Under the old code, a remote ASA5505 connected via Easy VPN Remote showed 1 IPsec tunnel. However, after the upgrade, it shows 42 sessions. It would seem to me that each split tunnel network defined in the Easy VPN profile is being counted as a tunnel. Is it possible that I may have something misconfigured now that the code is upgraded?

Cisco VPN :: Multiple Site To Site IPSec Tunnels To One ASA5510

Dec 4, 2012

Question on ASA VPN tunnels. I have one ASA 5510 in our corporate office, I have two subnets in our corporate office that are configured in the ASA in a Object group. I have a site to site IPSEC tunnel already up and that has been working. I am trying to set up another site to site IPSEC tunnel to a different location that will need to be setup to access the same two subnets. I'm not sure if this can be setup or not, I think I had a problem with setting up two tunnels that were trying to connect to the same subnet but that was between the same two ASA's. Anyways the new tunnel to a new site is not coming up and I want to make sure it is not the subnet issue. The current working tunnel is between two ASA 5510's, the new tunnel we are trying to build is between the ASA and a Sonicwall firewall.

Cisco :: Backup LMS 4.01 Don't Run

After the upgrade of LMS 3.2 to LMS 4.01 everthing works. After i fixed my last problem (syslog time issue). I´d saw that the automated system backup doesn´t work. I´d tried to backup the system by script. Than i find out that the perl.exe is damaged (0KB). So than i copied the perl.exe from my old Cisco Works Server to the new Server. Than i tried to make a Backup and get the mentiond error ...

Cisco VPN :: ASA With Backup Peer On L2L VPN?

Jan 10, 2013

Why does Cisco recommend a configuration of originate-only on the ASA with multiple peers configured and the answer-only to the other end? Shouldn't it work as Bi-Directional ?

The only scenario I see which could break is if both peers try to establish a VPN at the same time to the ASA. Is there any other reason ?

Cisco WAN :: ATM Soft Pvc Across T3 And T1 Backup?

I am trying to create a VBR soft pvc across a T3 and T1 backup link, but I am confused about what values to use for PCR, SCR and MCR.  If I use high values for the T3, what will happen when this link is down and the soft PVC reroutes across the T1?  I would like to use percents (%) for the values, i.e. voice can use 25% of the link, then it would make more sense when using the backup T1 link.

Cisco WAN :: 887 / ATM Router As Backup

May 31, 2012

at the moment I have a 888 router that works fine, I want to configure backup (I already have configure ISDN backup but the performance it's to poor), and I want to use an other router 887 (that I already have) with adsl.
My idea is to configure the second router as stand alone gateway, and confiure in the first router a "ip route VLAN1 100".But I know that this second route is used only in case the interface status of primary route goes down but not in case fault only protocol.
configure a better routing or faulting procedure?
ip route ATM0.1
ip route VLAN1 100
ip route ATM0.1

Cisco :: Backup WAN Connections With OSPF?

Feb 11, 2013

implement backup WAN links to complement the metro Ethernet links we currently use so we have some redundancy. These will most likely be a VPN over an Internet service but might be another Ethernet type service, the medium shouldn't really matter I wouldn't think. What I am looking for input on is what is the best way to implement this? Would I just set costs so that the backup is only used when the primary goes down, or should I create new OSPF area for the backup links?

Currently the core switches that are also our routers are 3750G stacks running ip services. We are getting ready to install new firewalls at each location that will become the gateways for the vlans currently on the core switches to give us much more control over segmentation, and because of this I am thinking that it may make sense to then move the OSPF instance from the core to the firewalls. In the drawing I did not show the access layer switches off of the core, and the MOE circuits actually terminate into a 3550-12T switch before the core. I think I will actually eliminate those 3550-12T switches and go straight into the core. This is a current state drawing, so does not include the backup links I am planning.

Cisco :: LMS 3.2.1 - Cannot Backup Running Configurations In RME 4.3.2

Jan 18, 2013

Platform: LMS 3.2.1 with RME 4.3.2 on Windows 2003.I'm having a problem with several devices that were backing up fine until this week - suddenly they aren't backing up their running configurations, but RME is fetching their startup configurations fine and VTP backups are fine. At first I thought it might be timeouts, so I used inline edit to incease the telnet timeout for a device to 180s. However, the job fails well within this time period (debug shows on i/o error?). My order of protocols is SSH, Telnet, TFTP. I took a stab in the dark that this suggested a database problem so I picked one at random and deleted it from DCR, and readded it and it worked. However, for the other 48 devices affected it did not.
I'm wondering if I need to do anything to the RME database to get things back to where they were? Do I need to reinitialize the RME database, and if I do that what do I lose? [code]
