Connectivity Issues Cisco ASA 5515 in Transparent Mode

Hi,
we´re having problems with one transparent mode setup at one customer site. The ASA is equiped with a CX Module, but we´re not using it, so far in the service policy rules it was enabled and matched all traffic, but in "monitor only" mode. There is a global acl that allows any-any-IP.
Firewall-Info:
- ASA Version 9.1(2)
- Interfaces gi0/0 + gi0/2 without any interface errors
The ASA 5515x is configured as a "bump in the wire". In general our setup is working but with beginning of the installation of the firewall the customer faces following connection issues, without the firewall no problems:
- Connections to SAP-Servers behind the MPLS begin to drop, affected all users
- Incoming monitoring sessions (ping/snmp) from central management are facing ping timeouts, connection timeouts
- http downloads are stopping, Customer: it will stop responding and the download will fail.
In general the customer describes it this way: "We do not have the best connection here so once we connected the firewall all the problems are magnified"
I recognized, that we unconfigured the default inspection during initial setup and reconfigured this entry for the cx module. So the the default inspection with all the settings are not present any more... How important are these settings? One phenomen is, that I´ve seen a large numbers of concurrent connections that increased over time. And we already had that situation, that the firewall reached the max-conn count.
Should I try to reconfigure the default inspection, as it ships from factory? And whats the best way to check for problems? What can be the reason for the dropping connections?
I attached a network plan and the firewall config, hopefully, that somebody has an idea. Of course I can provide additional information...
Best Regards
Sebastian

Hi Vibhor,
thanks for your reply. Does this also affect the traffic, even the setting is set to "Monitor Only" ?
Is it recommend to configure the default-inspection rule as a default setting?
Further Question: I´ve read sth. about, that service policy rules must be "reloaded" to take effect, after they have been changed. Is that right and how do I reload them?
Here is an output from sh asp drop, do I have to care about certain values? This values result from two connected users doing some downloads over a 2Mbit connection.
ciscoasa# show asp drop
Frame drop:
Invalid encapsulation (invalid-encap) 10
First TCP packet not SYN (tcp-not-syn) 114

ASA 5510 in Transparent Mode-Guidelines.

Dear all,
I need to convert routed mode to transparent mode on my ASA-5510 with inbuilt IPS.
let me know which of the following features configured on my firewall will have issue if converted to transparent mode:
1. static routes.
2. object-groups.
3. ACLS.
4. URL-filter (Websense).
5. IPS . ( i doubt this )
6. have 3 data and 1 Mgmt interfaces.
7. syslog.
8. SNMP
I'm sure point 5 and 6 will have issues, need to confirm.
need to confirm this by EOD,
( 5 hours more).
thanks in advance.
Shukla.

Does not participate in routing protocols but can still pass routing protocol traffic through it. You can define static routes for the traffic originated by the ASA.
in transparante mode the devices dehind and infront of the firewall will be in the same ip subnet as the firewall will be a L2 device!!
ACLs can be configured normally
syslog as well
obgect groups as well
Address translation is inherent when a firewall is configured for routed mode. Beginning with
ASA 8.0, address translation can be used in transparent mode as well
Does not participate in multicast. However, it allows passing the multicast traffic through it using the ACLs.
Does not support QoS.
Inspects Layer 2 and higher packet headers
as long as u can use
policy-map global_policy
then u can integrate with IPS if u mean AIP-ssm modul
transparent also known as a Layer 2 firewall or a stealth firewall, because its
interfaces have no IP addresses and cannot be detected or manipulated. Only a single
management address can be configured on the firewall
In transparent mode, a firewall can support only two interfaces-the inside and the outside. If
your firewall supports more than two interfaces from a physical and licensing standpoint, you
can assign the inside and outside to two interfaces arbitrarily. As soon as those interfaces are
configured, the firewall does not permit a third interface to be configured.
Some platforms also support a dedicated management interface, which can be used for all
firewall management traffic. However, the management interface cannot be involved in
accepting or inspecting user traffic
Configure a management address:
Firewall(config)# ip address ip_address subnet_mask
The firewall can support only a single IP address for management purposes. The address is
not bound to an interface, as in routed mode. Rather, it is assigned to the firewall itself,
accessible from either of the bridged interfaces.
The management address is used for all types of firewall management traffic, such as Telnet,
SSH, HTTP, SNMP, Syslog, TFTP, FTP, and so on.
A transparent firewall can also support multiple security contexts. In that case, interface IP
addresses must be configured from the respective context. The system execution space uses
the admin context interfaces and IP addresses for its management traffic
You do not have to configure a static route for the subnet directly connected to the firewall
interfaces. However, you should define one static route as a default route toward the outside
public network
i wish i covered all ur questions
good luck

Trying to figure out whether I can use an ASA cluster in Transparent mode to facilitate VRF based network ??

Hi Guys,
I had to re-post this here because I did not get any comments earlier.. hopefully I'll get something here.. :)
I'm investigating the ways that I can use 2 x ASA (5525x) to accommodate Multi-tenancy situation with overlapping addresses. Unfortunately in this particular scenario we have to stick with 5525x firewalls.
The ASAs are going to be placed in north-south traffic path between 2 routers and these routers need to be configured with multiple VRFs to segregate the traffic for each tenant with overlapping IP subnets ( We are not looking at NAT as a workaround for the time being).
As we know, this ASA model won't support VRFs so we can't use the ASA as a intermediary routing hop and therefore this is not an option.. and using security contexts per VRF seems not scale-able enough (correct me if I'm wrong). So my thinking is that, if we put the ASAs in to the transparent mode and just use the ASAs as a layer 2 interconnect (configured with different VLANs connecting VRFs served by top and bottom routers) I should be able to go up to maximum of 50 VRFs (since 5525x only supports 200 VLANs).
I'm also planning to use the 2 ASAs in a cluster mode to aggregate the bandwidth of both ASAs for better throughput.
So I need to clarify following with you guys..
1) Can I actually do this or am I missing something.
2) Are there any limitations that I might run in to with this setup
3) Is there anyone out there who's doing the same thing or can you think of a better way to tackle this scenario (with same hardware and requirements)
4) Instead of using clustering, can I use simple Active/Stanby pare and still configure transparent mode and use it that way ?
Appreciate your input.
Thanks
Shamal

There is a limitation on how many context you can have, which depends on the license you have. This is quite possible with ASA multi routed mode and even with multi transparent mode. You can have overlapping ip in each context without the need of using nat as long as you have unique mac address for each sub interface.
Thanks

Cisco 2960S Configured in Transparent mode

I have a Cisco 2960S gig switch configured in transparent mode with multiple vlans configured. I have printers that I can ping, the ports shows up but on the printer it says offline. Any idea what could be causing this?

If your printer and your PCs are all in the same subnet and only the printer is not working then VTP mode Transparent has nothing to do with your issue.
I'd be keen to know if you have a firewall blocking anything from the IP address of the printer? Maybe the IP subnet mask or default gateway of the printer is not working?
What do you get when you do a "sh mac-address interface <PRINTER port>"?

ASA 55xx in transparent mode - switch ARP table?

Guys,
It's a basic question about how transparent mode firewalls communicate with the connecting switches.
My understanding is that if I separate the LAN eg. 10.1.1.x with a transparent firewall than it will only "snoop" the traffic and will not change anything in the Ethernet header.
Is it correct or still will replace the MAC address with the firewall physical interface address to send the frame to the connecting switch?
e.g.
client--------->switch------->transparent 5510-------->switch---------->server
10.1.1.1 10.1.1.100
When the client sends the ARP to look up the hardware address of the server then what will that received back?
The MAC address of the transparent ASA, or the server?
Thank you!

Source MAC address is never changed if the traffic is passing through same IP subnet (vlan). Here the firewall is in transparent mode and if it alter the source mac address communication will not happen. This is a very fundamental network concept. However it may recreate the same frame with same souce/destination mac addresses.

Single AIP-SSM in Cisco ASA Failover Active / Standby Mode

Hi,
I can add single AIP-SSM on Cisco ASA in failover active / standby mode?

No, both units need the same hardware, that includes the installed modules.

Disabling Any connect in Cisco ASA's

what is the best way to disable anyconnect in the Cisco ASA's.
Thanks

The quickest way to disable a remote access SSL VPN (the most common type by far when using Anyconnect clients) is to turn off webvpn ("no webvpn") in configure mode.

ASA 8.4 transparent mode active/active questions

Hi, currently i'm trying to create network design which uses two 5585-X in transparent mode with active/active load balancing (with states), but i have some questions:
1. Do i need to configure asr-groups in transparent mode? What will happen if my packet (or now more accurately frame) will return to the standby context of one device, while the initial packet passed through active context on the another device (contexts are in the same group but on different physical devices)?
2. In 8.4 we received new feature called BVI interfaces. How this feature integrates with failover functionality? Can we now use multiple BVI bridge groups for multiple vlans (instead of bridging a single pair of vlans in single context)?
3. When implementing active/active load balancing with BVIs do we still need to use multiple context mode?
Thanks for your replies

Hello,
1. Do i need to configure asr-groups in transparent mode? What will happen if my packet (or now more accurately frame) will return to the standby context of one device, while the initial packet passed through active context on the another device (contexts are in the same group but on different physical devices)?
You only need to configure ASR groups if your routing environment would match the scenario you outlined (a return packet arrives at the unit running the Standby context).
2. In 8.4 we received new feature called BVI interfaces. How this feature integrates with failover functionality? Can we now use multiple BVI bridge groups for multiple vlans (instead of bridging a single pair of vlans in single context)?
You can configure up to 8 bridge groups per context to achieve this.
3. When implementing active/active load balancing with BVIs do we still need to use multiple context mode?
Active/Active failover is only possible in multiple context mode.
Hope that helps.

Connectivity Issue between ASA 5520 firewall and Cisco Call Manager

Recently i have installed ASA 5520 firewall, Below is the detail for my network
ASA 5520 inside ip: 10.12.10.2/24
Cisco Switch 3560 IP: 10.12.10.1/24 for Data and 10.12.110.2/24 for Voice
Cisco Call Manager 3825 IP: 10.12.110.2/24
The users and the IP phone are getting IP from the DHCP server which configured on cisco 3560 Switch.
the Default Gateway for Data user is 10.12.10.2/24 and
for the voice users is 10.12.110.2/24
now the problem is that the users is not able to ping 10.12.110.2 call manager. please if somebody can help in this regard. i will appreciate the prompt response against this issues.

Actually i don't wana to insert new subnet and complicate the nework. i need a simple way to solve the problem. below is the details for the asa 5520 config.

ASA Routed or Transparent mode

Hi ,
I am planning to deploy ASA as internal Firewall ... as all the Inside and Outside zones will be having same Ip range . I am confused about its deployment . Can any1 help me on deciding on deploying it as Routed mode or transparent mode

Transparent.
Just the intro of the following file will answer your question:

TCP connections on Cisco ASA disconnects the database session every 30 Minutes

Right after a firmware upgrade form 8.4.2 to 8.4.7 on our ASA 5540:
the database app that makes a tcp connection with the database loses connection to the database servers on the inside of the firewall
-Nothing changed on the process servers.
-Nothing but firmware version changed on the firewalls.
-Rebooting did not help.
-Connections don't always drop every 30 minutes, but it's still almost exactly at that time, with a 90% chance of it happening. And it reestablishes in about 52 second
-The client is not willingly terminating the connections to the database servers on the inside. The connection is just going away.

I am not seeing any error in the logs in ASA but in our client we see:
Latest from PROD (times are in UTC):

Connection issues on Public Hotspot - Single App mode (MDM)

My iPad is connected permanently to a public hotspot. The connection sometimes is interrupted by a planned maintenance on the AP.
It happens from time to time that the iPad can't recover it's Wifi connection by itself.
Going to the settings> Wifi seems to be enough to reconnect.
Problem is that the device is working in An MDM Single App profile, and so the settings are not meant to be reachable.
Restarting the device is required to reconnect to the public AP.
I know that IOS sometimes turns down WIFI after a certain period of non-use, but in Single App, the iPad stays on, day and night.
It is running in IOS 7.1.
Is this a know issue?

anyone know how to set a correct task id?

Hi,
Maybe you are not falling into that tunnel-group SSL? By default, you will fall into the DefaultWebvpnGroup unless you choose the TG via a dropdown or directly access the group via a groupurl.
Example: When no 'tunnel-group-list' or 'group-url' is configured:
Accessing https:// will take you to DefaultWebvpnGroup.
When 'tunnel-group-list enable' is configured under webvpn, you will get a dropdown of tunnel-groups to choose from [provided you have an alias defined for the group]
When group-url is configured for a particular TG, say https:///test , on accessing that URL, you are taken to that group directly.
So basically, you would need to check which group you are hitting. Running 'debug webvpn 255' should also show you this.
Thanks

Cisco ASA 55XX Transparent mode VLAN traversing

Hello Cisco Forum Team!
In a scenario where the Cisco ASA is in Transparent mode, is it possible to transmit L2 traffic from other VLANs different than the native VLAN the management IP of the firewall resides?
The switches on the outside and inside interfaces of the ASA are in trunk mode and I am trying to pass L2 VLAN ttraffic from inside to outside and vice-versa using filters on the switches (switchport trunk allowed vlan).
Thanks in advanced for your support and comments!

Yes it is possible but you will be limited to 8 VLANs, or more accurately, 8 BVI interfaces so this is not a scalable solution. The catch is that you will need to have different VLANs for the same subnet at either end of the ASA.
To clarify this, lets say you are using interface Gig0/1 and Gig0/2. On Gig0/1 you would have configured subinterfaces with VLANs 2, 3, and 4. Now if you try to configure these same VLANs on Gig0/2 you will get an error saying something like this VLAN is already configured on another interface...I don't remember the exact error.
So to get this working you would need to configure Gig0/2 with subinterfaces for VLANs...lets say...5, 6, and 7. you would then associate VLANs 2 and 5 with BVI 1, VLANs 3 and 6 with BVI 2, and VLANs 4 and 7 with BVI 3. Each BVI interface would have its own IP address for the subnet that is being bridged across the ASA.
