ASA 5510 in Transparent Mode-Guidelines.

Question

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

good luck
