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.

Cisco WAN :: 2821 - MPLS And S2S Failover Management

Mar 10, 2013

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 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.

Cisco Firewall :: QOS By Protocol On ASA 5512-X

Apr 18, 2013

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.

Cisco Firewall :: ASA 5512 - SSL VPN Not Working

Nov 10, 2012

I have a windows 2003 server and an ASA 5512
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...

Cisco Firewall :: ASA 5512-X 8.6(1)2 NAT Overload

Feb 18, 2013

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.

Cisco Firewall :: ASA 5512-X DHCP Backup ISP?

Jun 3, 2012

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.

Cisco Firewall :: ASA 5512 - Best Way To Setup Identity NAT

May 2, 2013

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
static (inside,dmz) <IntSubB> <IntSubB> netmask
static (inside,dmz) <IntSubC> <IntSubC> netmask
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>
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 - 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)
Object-group network Inside_Subs
     network-object <IntSubA>
     network-object <intSubB>
     network-object <intsubC>
nat (inside,dmz) source static Inside_Subs Inside_Subs no-proxy-ARP route-enabled. What would be the best way to translate my Identity NATs?

Cisco Firewall :: Does The ASA 5512-X Require A Separate HA License

Mar 25, 2013

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?

Cisco Firewall :: ASA 5512 WCCP Configuration With Web Filter

Oct 31, 2012

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 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 Barracuda IP   All PCs in the subnet use the ASA as the default gateway and should have web requests redirected to the Barracuda. 
Below are the respecive bits of my ASA config
interface GigabitEthernet0/0
description Management
speed 1000

I suspect my issue is that the ASA is generating a Router Identifier of which is my inside network and the barracuda cannot communicate with it.  how I can get this working ?

Cisco Firewall :: Unable To Open SMTP Session Through ASA 5512-X?

Just doing some basic testing before we replace our ancient PIX 515E with a new 5512.

I can ping all the way outbound from to, and the machine shows it is translated properly to

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?

Cisco Firewall :: 5512 - BGP Through ASA Versus Transparent Mode Deployment

Mar 8, 2013

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 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?
