Sophos Xg Ipv6

Sophos is very committed to providing IPv6 support across all areas of XG Firewall. This document summarizes the features supporting IPv6 as of XG Firewall v16. We will continue to invest further in IPv6 for future releases and update this document accordingly. List of features supporting IPv6 Following SF features support IPv6. The Sophos XG Firewall can use a static DNS. By adding a static DNS entry for a particular domain name, the Sophos XG Firewall resolves the domain name itself and the request will not be forwarded to a DNS server.

Running IPv6 by default could allow attackers to bypass security controls and wreak havoc. Sophos protection. As use of IPv6 increases, security requirements evolve. Sophos has invested in capabilities in our endpoint products to restrict the use of IPv6 until you’re ready to use it. The switch to IPv6 may seem overwhelming, but take it step by step and make sure all your bases are covered.
No one has figured out how to run code with this bug yet – but if they do, you can bet that someone will turn it into a computer worm.

How to configure DoS & DDoS protection

This article describes how you can protect your network against DoS and DDoS attacks using the Sophos XG Firewall (SF). It is divided into two sections:
- Protecting your network from a DoS attack
- Protecting your network from a DDoS attack

Protecting your network from a DoS attack

You can protect your network against DoS attacks for both IPv4 and IPv6 traffic by configuring the appropriate DoS Settings on the Sophos XG Firewall. Sky go apple tv 2019. You can configure DoS Settings by following the steps below:

Sophos Xg Ipv6 4to6

Navigate to Intrusion Prevention > DoS & Spoof Protection.
Set the Packet and Burst rates under DoS Settings section according to your network traffic and check the Apply Flag next to the parameter to enable scanning for the respective type of traffic.
- As an example, we have set Packet rate per Source (Packet/min) as 1200 for ICMP/ICMPv6 Flood and checked the Apply Flag next to it to enable scanning for ICMP and ICMPv6 traffic.
Click Apply to apply the configured DoS Settings.

Once DoS settings are applied, SF checks the network traffic to ensure that it does not exceed the configured limit.

Protecting your network from a DDoS Attack

You can protect your network against DDoS attacks by using Intrusion Prevention policies in SF. To configure an IPS policy, follow the steps below.
Navigate to Intrusion Prevention > IPS Policies.
Click Add to create a new Intrusion Prevention policy named DDoS_Protection.

Click Save.
Click on the icon for the DDoS_Protection policy.
Click on Add to create a new rulenamed DDoS_Signatures.
In the Smart Filter field, type “ddos” (without the quotes) and then press enter.
Set the Action to Drop Packet.

Click on Save and then click on Save again to save the policy.
Navigate to Firewall and apply the Intrusion Prevention policy to the User/Network Rule.

You must configure the auxiliary device before you can configure the primary device and enable HA.

Go to System services > High availability.
Specify the initial HA device state.

Specify the HA configuration mode for the cluster.

Active–Active

The primary device receives all network traffic and load-balances the traffic using the auxiliary. Both the primary and auxiliary devices process traffic. The auxiliary takes over if a power, hardware, or software failure occurs on the primary.
Active–Passive	The primary device processes all network traffic and the auxiliary remains in stand-by mode. The auxiliary becomes active and takes over only in case of a power, hardware, or software failure on the primary.

Select Interactive mode.
Assign a Cluster ID, if required.
A cluster is a pair of devices operating in HA. Devices in the same cluster must share the same cluster ID.
If you have multiple HA clusters, assign a different ID to each cluster.
A Passphrase is generated automatically. You can also change the Passphrase manually.
Note The devices in the cluster must have the same passphrase.
Select a dedicated HA link.
Dedicated HA link
The link to be monitored. Peers in an HA cluster continuously monitor the dedicated HA link and the interfaces configured to be monitored.
Note The peer device must use the same HA link. Specify this port as the HA link port on the peer. For example, if you choose port E on the primary device, you must also choose port E on the auxiliary device.
Note The IP address of the HA link for the peer device must be on the same subnet.
Select ports to be monitored for HA status.
If any monitored port goes down, the device will leave the cluster and failover will take place.
Note This feature is not supported in virtual security devices.

Specify Peer administration settings

Interface

Port that is used for administration purposes on the auxiliary device.
IPv4 address	IPv4 address that provides access to the administration console of the auxiliary device.
IPv6 address	IPv6 address that provides access to the administration console of the auxiliary device.

NoteYou can't enable HA if you turned on STP on a bridge interface.

Note To access the peer administration IP address you must use a machine within the same LAN network, and the access must not be established through the primary device.

Specify the keepalive request interval in milliseconds. You can use a value from 250 to 500. Default is 250.
Specify the number of keepalive attempts. You can use a value from 8 to 16. Default is 16.
Note You can't set the keepalive interval and keepalive attempts for devices in standalone and fault modes.
Select the checkbox if you want to use the hypervisor-assigned MAC address. This option is available only with virtual appliances.
This removes the need to turn on promiscuous mode on the vSwitch.
Specify if the system should fallback to the primary device when it recovers.
In the event of failover, traffic will be routed through the auxiliary. If you want this to automatically move back to the primary device when it recovers, select this option. Datamax 4212 mark ii manual.
Note If the device is in standalone or fault mode, this functionality will not be supported.
Click Initiate HA.
The primary device pushes its configuration to the auxiliary.

When HA is active, the devices will synchronize automatically. To force the device to push configuration updates to the auxiliary, click Sync auxiliary.

If you have configured the device for Active–Passive mode, you can force the auxiliary to take over as the primary device by clicking Switch to passive.
