How to send as/from a distribution group with Exchange 2010

To grant a user the permission to send from a distribution group you will need to open Active Directory with the view set to “Advanced” then open the properties of the Distribution group you wish to modify, and select the “Security” tab. Click the “Add…” tab to add the users who will be sending as the group.
Once you’ve added the users, check mark Allow for “Send as” under “Permissions for SELF” make sure to uncheck all other permissions.
Remember to allow time for the changes to replicate, and send a test message to you to confirm the changes took effect.

Update ASA Firmware in Failover

Upload the ASA image and ASDM to BOTH active and Standby units.

On the Primary, set it as the Boot Image and ASDM Active image.
On the Secondary just transfer the file over.

Reboot the Standby Unit
failover reload-standby

Once the secondary firewall is ready, it should show Standby-Ready

Make your Primary Firewall the standby
no Failover active

Now you can reboot the primary firwall, which is now the standby firewall.
If you are SSHed in, you would then again issue
failover reload-standby

If you are consoled in to the primary firwall, then just run
reload

Once its been rebooted, and the primary firewall is showing as Standby-Ready
On the Console of the primary, run this
failover active

Setup Cisco ASA in Active / Standby Fail-over

You will need a Crossover cable to connect the two firewalls together.

Start with the First Firewall Unit.

Clear the Config for the Failover Interface

clear configure interface m0/0
int m0/0
no shut

Set the Interface for Fail-over
failover lan interface failover m0/0

Setup IP address for the Fail-over Interface
failover interface ip failover 172.16.254.254 255.255.255.0 standby 172.16.254.250

Create Standby IP address for EVERY SINGLE Interface you have now, or add later

interface Ethernet0/0
ip address 192.168.1.1 255.255.255.0 standby 192.168.1.254

Create and setup shared Key for Failover
failover key 123456

Define this firewall as the Primary
failover lan unit primary

Activate Failover Feature
failover

Turn on Stateful Failover

failover link failover M0/0

Save Config
<code>Write mem

Now work on the second firewall (standby)

Go ahead and connect the two together for the failover connection

Clear config for the failover interface

clear configure interface m0/0
interface m0/0
no shut

Set the Interface for Fail-over
failover lan interface failover m0/0

Setup IP address for the Fail-over Interface
failover interface ip failover 172.16.254.254 255.255.255.0 standby 172.16.254.250

Set the shared Key for Failover (Same as the one you created before)
failover key 123456

Define this firewall as the secondary unit
failover lan unit secondary

Activate Failover Feature
failover

To check things out
show failover

You can connect to the Primary ASA and adjust the Timeouts if you wish

failover poll 1 hol 3
failover poll interface 3
int m0/0
failover poll interface 3

When you save your config, the changes will be replicated to the standby unit.
