This is a quick published article that doesn’t include much detail but will give you very helpful hints.

WatchGuard uses Proxy settings to achieve such resolution. WatchGuard can act as a proxy to intercept HTTP/HTTPS requests in order to allow or deny access to sites based on source or destination networks or ports according to Policies built on it

When you choose to create a new policy in WatchGuard, you can choose it to be a packet filter (normal non-proxy rule), or a proxy policy. Now, create an HTTP-Proxy rule that includes that source network you want to apply the web-blocker to. Build another HTTPS-Proxy rule and apply it to that network, the same way. Then you can build two HTTP and HTTP (non-proxy rules, i.e packet filter) above them to allow other networks to bypass proxy policies that web blocker depends on. In the source network address of the non-proxy rules list only the networks that the proxy won’t apply to.

Now, instead of using a Web browser to access and manage the WatchGuard XTM/UTM admin portal, download and install WatchGuard System Manager… It’s much easier to work with and build the rules/policies what you want to.

After that, login in using the WatchGaurd System Manager, and from Tools menu click on Policy Manager to launch it. From Policy Manager click on Subscription Services, then WebBlocker and activate it.

Resolution:

Took me a while to figure it out. The error was happening to me because the Shadow Copy setting for C:\ was set low for VSS to operate. Increasing that disk space fixed it! Right click on C: drive, Properties, Shadow Copies, Highlight C:\ (Even though shadow copy might be disabled),click Settings –> Under Maximum size, change it to a bigger size., I set it to 300G to test it and that worked for me.

If Exchange Stores are located on a different drive, adjust that drive shadow copy setting.

Example: Cisco RV082 One To One NAT – Access Rules Example

Example:
Public IP Address: 75.75.75.75
Private IP Address: 192.168.1.10

In this example we will NAT 192.168.1.10 to 75.75.75.75 and open up TCP Port 23 (Telnet) to the inside host from outside.

– Login to the Cisco RV 082 through the browser
– On the left click on Setup then One-To-One NAT
– Click Enable One-To-One NAT. In the Private Range Begin: fill in 192.168.1.10. In the Public Range Begin type 75.75.75.75. In the Range Length type 1. Click Add to List. Click Save.

Click on Firewall on the left.. Click Access Rules. Click Add.
For Action click Allow
For Service choose TELNET TCP 23-23
For Log: choose the option you want
For Source: choose the outside interface of the Router. In my case it is WAN 1
For Source IP: Choose ANY (if you would like it to be available to anyone on the Internet
For Destination: Choose the Inside IP address of the NAT 192.168.1.10 (NOT The Public IP Address)
Click Save

Now create a new rule to deny any other access to the NAT’d host:
Click on Firewall on the left.. Click Access Rules. Click Add.
For Action click Deny
For Service choose Any
For Log: choose the option you want
For Source: choose the outside interface of the Router. In my case it is WAN 1
For Source IP: Choose ANY (if you would like it to be available to anyone on the Internet
For Destination: Choose the Inside IP address of the NAT 192.168.1.10 (NOT The Public IP Address)
Click Save

Symantec Backup Exec backup to USB Disk – 546 The log file sector size does not match the sector size of the current volume – Microsoft Exchange Information Store (IS) using Granular Restore Technology (GRT).

Scenario:

You are backing up Exchange 2007 Information Store running on Windows Server 2008 R2 with Symantec Backup Exec 12.5 and you have selected to use Granular Restore Technology (GRT) in order to be able to restore individual mailboxes and email items. Backup is failing with the following error:

Backup- \\Email-Server\Microsoft Information Store\First Storage Group V-79-57344-759 – Unable to complete the operation for the selected resource using the specified options. The following error was returned when opening the Exchange Database file: ‘-546 The log file sector size does not match the sector size of the current volume. ‘

Solution:

In my case I was backing up MS Exchange server into a 3T Byte USB disk that had Bytes Per Sector format of 4096, while Exchange was on a server with Bytes Per Sector disk of 512… The backup software didn’t like that! My solution was to use a 2T Byte USB disk which by default had the same 512 Bytes Per Sector matching the Exchange Server disk.

To find out the Bytes Per Sector for Exchange server disk, type the following on the Exchange server:

fsutil fsinfo ntfsinfo c:

To find out the Bytes Per Sector on the USB disk, type:

fsutil fsinfo ntfsinfo F: (assuming that F: is the USB disk drive),
