Cisco Firewall :: ASA 5512 8.6(1) Failover Via Management
Jun 9, 2013
I am configuring a brand new pair of ASA 5512s running 8.6(1). Traditionally we hae been using the Management port as the dedicated failover link, but that seems to not be possible on the 5512s.
ASA (config-if)# no management-only ERROR: It is not allowed to make changes to this option for management interface on this platform.
I have not been able to find anything in the official documentation mentioning this restriction.
Most of my remote site is running MPLS primary (2821) and DMVPN (881) as a backup solution..Some of my sites run MPLS primary on 2821 and site to site as back up on 881 router.. MPLS here means the router that connected me to MPLS cloud of provider, not running any mpls..it is easy that way for us..
When MPLS is down,
The way s2s tunnel gets triggered is via HSRP on LAN i.e, the HSRP VIP is served by the 881..At the far end data center, the MPLS route of remote site is purged out, there is static route with higher admin distance will get into routing table.
Remote site A LAN----- MPLS Router-----MPLS cloud-------MPLS router----------------Data Center LAN Remote site A LAN----- DSL Router-----internet cloud--------Data center ASA----------Data Center LAN
In the MPLS plus s2s model, I often get into problem...the problem is how do I manage the 881 router via snmp, ccm , tacacs or any other management tools? There is a routing issue in hand that I canno route to and from to the mgt address of DSL. I cannot reach the loopback or mgmt vlan of the DSL router when the MPLS is active…but this will disallow all the management stuff we do on the DSL router.
I'm looking to make a possible configuration for a customer. They need a device to provide :- firewalling- bandwidth limiting based on protocols, IP, users- web content filtering- good reporting to see which device/users are consuming most of the bandwidth.I used to use cisco ASA as firewall but it's a while I last installed on and I'm nt uptodate which current state.So I thought of using an ASA 5512-X but I'd like to know if it comply with all the requirements .Most important being the reporting and bandwidth limiting capability. It would be great to have some configuration example regarding bandwidth management.
I'm trying to use SSLVPN and it was all working, and I don't believe any configs on either box have been changed.
On Friday people were connecting, but now I get a message "Login Error" in the browser. In the ASDM home 'latest ADSM Syslog Messsages' I get "AAA authentication server not accessible", followed by two messsages AAA Marking LDAP server in group as FAILED AAA Marking LDAP server in group as ACTIVE
When I go to configuration --> Remote Access VPN --> AAA/Local Users AAA server groups and click on my RADIUS server and click Test, it takes a while and says ERROR: AD agent Server not responding: No error
If I stop my IAS server on my Windows box i get the same error but much more quickly.
I have a sonciwall set up doing the same thing, and RADIUS seems to work happily, so I don't think it's the server config...
My collegue and I have been trying to figure out why we are unable to get this ASA to NAT Overload correctly. I'm sure it is something stupid, and the config may have gotten a little dirty as we tried to change options and make it work. FYI, we can ssh from the WAN into the device to configure it. It is communicating externally, but it isn't natting.
I have a customer who needs a 5512-X set up with two ports on the "Outside" interface and act like a switch on the outside. This is very easy to do with the way the ASA 5505 works just by creating vlans and treating the ports as members of the vlan.
I am having soem difficulty getting documentation and setup procedures for the new ASA 5512-X (or X models in general) firewalls.I know the IPS sensor is a software-based one, but I'm not sure how much different the setup in than with a 5510 and IPS module.
I installed a new ASA 5512-X over the weekend for a client. Their backup ISP connection is DHCP based. I need to use the 'dhcp client route track' command on the interface, but it is not available. However according the all the documentation I am looking at and even the ASDM says it should be available.
This is the version of ASA and ASDM they are running:
Cisco Adaptive Security Appliance Software Version 8.6(1)1 Device Manager Version 6.6(1)
I did upgrade to the latest ASA software, so has this command been removed? If I do a '?' in the interface, there isn't a 'dchp' option.
I'm porting our configuration from a Pix 515 firewall to an ASA 5512x. What's vexing me right now is with the deprecation of the "static" command, I can't quite figure out the best way to Identity NAT my inside sub nets (multiple) to the DMZ sub net
So on the pix I have my identiy NATs as an example: static (inside,dmz) <IntSubA> <IntSubA> netmask 255.255.255.0 static (inside,dmz) <IntSubB> <IntSubB> netmask 255.255.255.0 static (inside,dmz) <IntSubC> <IntSubC> netmask 255.255.255.0
Cisco's migration guide seems to do them one object at a time, which I guess is straightforward enough to do: object network SubA subnet <IntSubA> 255.255.255.0 [code]...
I'm thinking that there must be an easier way (aka less lines) to implement this for all the sub nets I want to Identity NAT to the DMZ. 1) Can I do this creating objects using a sub net with a net mask of 255.255.0.0 - one object to cover multiple internal sub nets? 2) Can I do this using object groups and trim this down to: (assuming I have to commands right)
If you look at the data sheet for the 5512-X the High Availability section states "Not Supported; ActiveActive or ActiveStandby" while the ASA 5515-X states "ActiveActive or ActiveStandby". What does "Not Supported" mean for the ASA 5512-X? Does this mean HA does not work, or that I need to purchase an additional license to use the HA feature?
I have a Cisco 5512 x Firewall connected with Cisco Layer 3 switch 3750.I have two different WAN connections, one for Data and one for voice. Cisco Layer 3 switch is configured with 2 different VLAN's one for data & other is Voice Vlan. Switch is providing DHCP to computers and IP phones. Voice Pool 192.168.10.0/24 Vlan10 and Data pool 192.168.20.0/24 Vlan20.I need to route my data & voice traffic separately. Cisco ASA is connected with two different ISP's. So, how can I do this configuration so that Voice and Data traffic will route separately.
I am having an issue where I can't connect to VPN after upgrading the license. The license upgraded is related to AnyConnect VPN. I noticed from the newly upgraded license, the Encryption-3DES-AES is disabled whereas previously it was enabled.
I am currently trying to enable WCCP between a Cisco ASA 5512 firewall and Barraccuda Webfilter 410 Vx applicance. The ASA firewall is running IOS version 8.6(1)2 and the Barracuda is funning firemware 6.0.0.013. Both the ASA and Barracuda are in the same network and can ping eachother. The ASA has several interfaces, outside, inside, data and dmz. The PCs and barracuda appliance are behind the data interface. ASA data IP 172.16.18.1 Barracuda IP 172.16.18.40 All PCs in the 172.16.18.0/24 subnet use the ASA as the default gateway and should have web requests redirected to the Barracuda.
I suspect my issue is that the ASA is generating a Router Identifier of 172.21.20.1 which is my inside network and the barracuda cannot communicate with it. how I can get this working ?
Configuration of inter-vlan routing on ASA 5512 ver 8.6? I have everything configured (un-nat, access-list, etc.) but still not working. When i do a packet capture, it says the traffic is denied by the implicit acl. Here is my config:
interface GigabitEthernet0/0.100 vlan 100 nameif data security-level 100 [Code]...
where I can find detailed documentation on these two products. Particularly, I am looking for high availability capabilities and any license requirements.
I have a problem with random host's geting the wrong source address on a ASA 5512-X 8.6(1). Right now there is a host, 192.168.25.108, showing up with 6.6.6.6 (fake) on whatsmyip.org, should be 5.5.5.5 like the rest of 192.168.25.0/24. In the xlate tabel I cant find anything wrong. Same yesterday with two host, that are using the right NAT address today.
Just doing some basic testing before we replace our ancient PIX 515E with a new 5512. I have a mini lab set up following the diagram below, although I am unable to telnet through to the mail server's netcat listener on port 25 TCP. I can ping all the way outbound from 192.168.101.1 to 10.0.0.2, and the 10.0.0.2 machine shows it is translated properly to 200.225.117.1.
NAT and access rules are as follows:
object network mail host 192.168.101.1 description Mail relay access-list inbound extended permit ip any host 200.225.117.1
[code]....
EDIT: Somehow the new global access rule is involved. When adding a permit any any in there I can get to the mail server no problem. When I remove it but leave in my permit ip any any on the outside interface, I am denied?
if on the ASA 5512-X virtual contexts are supported with version 9.1 ?
I found different information on the Cisco web, the ASA datasheet says it is supported but in the configuration guide I found exactly the opposite information.
Cisco ASA Series General Operations CLI Configuration Guide 9.1 and 8.6 [URL]
Cisco ASA 5500 and ASA 5500-X Series Next- Generation Firewalls for Small Offices and Branch Locations Data Sheet (Updated) [URL]
Is the 5512 able to be field upgraded to a 5515 and so on through 5555? I.E. Can I add ram and other hardware to make the boxes more powerful as my requirements increase? I was hoping this would have been a new feature with the ngen firewalls.
I've been asked to deploy an ASA in Transparent Mode because of concerns of putting another layer 3 hop between PE and CE routers running BGP.
Is there some problem with allowing BGP to flow freely through an ASA the is also terminating site to site and remote access vpn tunnels?
I just don't see the need for Transparent Mode here and you cannot have a standard DMZ setup with Transparent Mode: you have to use bridge groups to provide for multiple interfaces on the ASA and then have an external router route between those bridge groups.
what I'm missing here as to why Transparent Mode is needed (not needed)
I have created a VPN connection for ASA 5512-X by using the wizards and nothing seems to be wrong on the wizards's config.I am able to connect to the network by using the VPN but unable to ping internal network.Below is my config for your reference:
Result of the command: "sh run" : Saved : ASA Version 8.6(1)2 ! hostname FAA-ASA-1 enable password crzcsirI44h2BHoz encrypted passwd 2KFQnbNIdI.2KYOU encrypted
I have a Cisco ASA 5505 in our office. We are currently using Interface 0 for outside and 1 for inside. We only have 1 Vlan in our environment. We have two three switches behind the firewall. Today the uplink to Interface 1, to the firewall, on the switch went bad. I want to setup a second inside interface on the firewall and configure it as failover incase this happens again. I want to attach it to the other switch. Can I do this? If so, what do I need to do? would it only be a passive/standby interface?
we are having a firewall asa 5520 .we have connected the management port and inside port to internal network and dmz port to dmz network.now we need to configure tacacs and other management tool on dmz devices through management port. The problem is the management devices tacacs and other are placed in internal network.
I got PIX 525 with failover. Due to power issue one Unit was offline for a while. During this time couple of changes was done on the Firewall.
Which Unit becomes active when I plug the Firewall unit which was offline for a while now. Each Unit has 4 Ethernet Connection E 0/0 - connects ISP Router E 0/1 - connects to Lan switch E 1/0 - connects to DMZ port E 2/0 - connects to failover unit PIX
Currently we have one ISP1 and all traffic goes to this way. Suppose our isp1 goes down, our outside user cant get the server. All servers are nated to this ISP1.We planned to purchase a another ISP2. Shall we Configure same inside server to map this ISP2? so that one primary ISP1 goes down it will take place the outside trafficISP2.
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.
