Q: I would like to configure IPSec VPN at home connecting to our office PA Firewall. What’s your recommandation?
A: You may want to try an SSL-based VPN. Check this OpenVPN http://openvpn.net for more details. It runs on practically every platform, can use pre-shared keys or an X509 PKI, and works perfectly behind firewalls; it uses one port, UDP 1194. It’s also a bit more “standardized” than IPsec-based VPNs, as the server and client are both the same program, and behave nearly identically on every platform, something that CANNOT be said for IPsec servers/clients. In my experience, OpenVPN is MUCH easier to setup/manage than the various implementations of IPsec.
When deleting a checkpoint, it will merge snapshot files (avhdx) that will use 1.5 spaces. For example, if avhdx uses 1TB spaces, you may need 1.5TB spaces. The space combines size of the main VHD file plus all the snapshots that you are going to merge. Therefore, before deleting checkpoint, make sure you have enough free disk space.
You can see the snapshot’s size by right clicking on it, selecting settings and then clicking on the inspect button or by visiting the folder where your aVHDX files are stored.
Checkpoint uses a lot spaces, especially when a VM uses a lot spaces. Deleting these old checkpoints can be time consuming, stressful and occasionally downright ugly if you run out of disk space. We don’t recommend to enable it in a production environment. If you do take a checkpoint for some reason, be sure to erase it as soon as possible.

3. You should now see the rommon prompt:
rommom #0>
4. Enter the confreg command to view the current Configuration Register setting: rommon #0>
5. The appliance will most probably have the default Configuration Register setting of 0x01. Answer no when it asks you if you want to change the Configuration Register setting. 6. Change the Configuration Register to 0x41, which causes the appliance to bypass its saved config at boot

In a case you would like to have the calls redirect to your cellphone, you can set the Mitel phone’s Custom call forwarding calls to your mobile phone. You as administrator can do it on the Mitel Director or the user can do it on Mitel Connect.
A. Configure external assignment on Mitel Director
B. Mitel Connect
1.. With Mitel Connect open, click Connect>Settings.
2. Click on Call Routing and select Custom in When session.
3. Click Start Wizard. Enter your mobile phone # and other info. Click Next to continue.
4. Configure how many ring before forwarding the call to voicemail. Click Next.
5. In this settings and the following, you can keep the default and click Save to save the configuration.
Make sure the VM is turned off. Right-click on the VM. You will have an option to upgrade configuration version to 8… which warns you that after you upgrade, you won’t be able to migrate or import to Hyper-V servers of previous versions.
The cache timeout on Palo Alto Networks firewalls is 30-minutes (1800 seconds) for ARP entries on all interfaces, which is a fixed setting and cannot be adjusted. If you do want to clear the ARP manually, you may run a commend line.
To show arp status, run this command: >show arp all
To clear arp on ethernet1/1, run these command: >clear arp ethernet1/1
To clear all arp, run this command: >clear arp all.
