Configuring Two Sonicwalls To Use Layer 2 Connection with Failover
This is a summery of how you can connect a layer 2 (point to point/direct connection) between two Sonicwalls using SonicOS Enhanced 5.8. This is also a summery of how you can use the second Sonicwall’s WAN as a failover connection for the first Sonicwall.
On the first Sonicwall, plug layer 2 connection into an interface. For this example we will use X5.
Network->Interfaces
Zone: WAN
IP Assignment: Static
IP Address: 10.10.10.1
Subnetmask: 255.255.255.0
Default Gateway: 10.10.10.2
DNS Server 1: 208.67.222.222
DNS Server 2: 8.8.8.8
DNS Server 3: 208.67.222.220
On the second Sonicwall, plug layer 2 connection into an interface. For this example we will use X5.
Network->Interfaces
Zone: LAN
Mode/P Assignment: Static IP Mode
IP Assignment: 10.10.10.2
Subnetmask: 255.255.255.0
For failover and the ability to use the second Sonicwall's WAN for the first Sonicwall's WAN...
On the first Sonicwall
Network->Failover & LB
Check Enable Load Balancing
Check Respond to Probes
In the Groups section Click Configure for Default LB
Type: Basic Failover
Check Preemp failback to preferred interfaces when possible
Highlight X5 interface and click Add
Order desired interface and click OK
Click Configure for X5
Select Logical/Probe Monitoring enabled
Select Probe succeeds when either Main Target or Alternate Target responds
Main Target: Ping (ICMP) Host: 4.2.2.1
Alternate Target: Ping (ICMP) Host: 8.8.8.8
Default Target IP: 208.67.222.222
Click OK
Click Accept

Outlook Archive Using Received Date Instead of Modified Date
By default, Microsoft Office Outlook archives different items based on the item type:
- Email message: The received date or the last modified date and time, whichever is later.
- Calendar item: The last modified date and time or the actual date that an appointment, event, or meeting is scheduled for, whichever is later.
- Task: The completion date or the last modified date and time, whichever is later. Tasks that are not marked as completed are not archived. Tasks that are assigned to other users are archived only if the status is completed.
- Note: The last modified date and time.
- Journal entry: The date when the journal entry is created or the last modified date and time, whichever is later.
- Contact: Not archived.
After you create and configure the ArchiveIgnoreLastModifiedTime registry value, Outlook archives different items based on the following conditions:
- Email message: The received date.
- Calendar item: The actual date that an appointment, event, or meeting is scheduled for.
- Task: The completion date. Tasks that are not marked as completed are not archived. Tasks that are assigned to other users are archived only if the status is completed.
- Note: The last modified date and time.
- Journal entry: The date when the journal entry is created.
- Contact: Not archived.
Save the following to a .reg file and then double click the file to automatically add the entries to your registry.
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\Preferences]
"ArchiveIgnoreLastModifiedTime"=dword:00000001
[HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Preferences]
"ArchiveIgnoreLastModifiedTime"=dword:00000001
[HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\Preferences]
"ArchiveIgnoreLastModifiedTime"=dword:00000001
