IPSec Tunnel Active-Active Configuration Packet Loss Issue
Hi All, We configured with IPSec Tunnel Active-Active Configuration but we are facing packet loss post Active-Active configuration on IPSec and forced to work on Active- Passive configuration which results in not using both links in the branch. We are using 2 Network links in the Branch and we have Fortinet SDWAN at Branch and IPSec tunnel is created to route all internet to Cato PoP . We are trying to leverage "Multiple Active Tunnels for IPsec Sites "
Post Quantum Cryptography?
The PQC topic is increasingly being raised - what is the current Cato Networks stance on it? My searches only come up with a rather dismissive blog article from last year (https://www.catonetworks.com/blog/is-recent-quantum-hype-by-google-willows-chip-a-threat-to-rsa-algorithm) while competing vendors (that shall be unnamed) are seemingly taking a very aggressive approach - both for preparing to implement these algorithmes into their products as well as being able to detect/block the use of such protocols currently.
Blocking icloud private relay "nicely"
I would like to block "icloud private relay" in such a way that the user would be notified and able to continue without icloud private relay. Apple's recommended way to do this is to block DNS requests to mask.icloud.com and mask-h2.icloud.com so a "no error/no answer" or NXDOMAIN response is returned. This alerts the users that they either need to disable private relay or choose another network. Details are here: Prepare your network or web server for iCloud Private Relay - iCloud - Apple Developer Is there a way to configure this using only Cato? I cannot see how to create a custom DNS rule to block specific queries, and I cannot see how to create a custom IPS rule either. Is there a recommended way to do this? What are others doing? I am in a Windows shop. I could redirect DNS queries to a Windows DNS server and use DNS query filtering, but would rather do a Cato only solution if possible. Per Apple: Some enterprise or school networks might be required to audit all network traffic by policy, and your network can block access to Private Relay in these cases. The user will be alerted that they need to either disable Private Relay for your network or choose another network. The fastest and most reliable way to alert users is to return either a "no error no answer" response or an NXDOMAIN response from your network’s DNS resolver, preventing DNS resolution for the following hostnames used by Private Relay traffic. Avoid causing DNS resolution timeouts or silently dropping IP packets sent to the Private Relay server, as this can lead to delays on client devices. mask.icloud.com mask-h2.icloud.comEndpoint Device DNS Resolution
When Cato is handling DHCP and DNS for all devices within an account across multiple vlans, across multiple sites, is it possible for a device to resolve the IP of a hostname outside of the local subnet that the device is on, using Cato DNS to resolve the hostname? We historically have had on-prem Windows AD providing DHCP/DNS which reliably provided name resolution from hostname to IP, but also reverse DNS for IP back to hostname. We are moving to Entra ID/Intune+Auto Pilot managed devices with the outlook to retire our on-prem servers entirely. We have various use cases where we need to resolve a hostname to have the IP returned, but also for the IP to resolve back to hostname via reverse DNS. This has become difficult for Entra ID managed devices unless the device is on the same local subnet where the site switch manages the resolution via the local mac table. Is mDNS the right approach and where I should focus my attention or is there an alternative I should consider? As is looks like mDNS is restricted to vlans within the same site, it may not work in our scenario where we need to resolve across sites. Any advice or recommendations are greatly appreciated.Azure Virtual Desktop - Always on policy
Hello! What is best practise for implementing the always on policy for Windows 11 VMs (hybrid domain joined). At the moment if a user session expires the Cato tunnel seems to break. The AVD shows as unavailable in Azure and the user is no longer able to login. Only workaround so far is using the serial console to disable the Cato network adapter or uninstall Cato altogether. Is there a way for the session to still expire while making the domain and other prerequisite AVD features still accessible? Thanks!Anti-Tampering Query- Auto upgrade of client version
In the EA documentation , it is written that :- As part of the Anti-Tampering protections, when Anti-Tampering is enabled, by design, the Client can't be upgraded. To enable an upgrade either manually or using an MDM, there is a specific bypass code that is not connected to disabling Anti-Tampering for the configured duration. My query is as below:- If my policy in client rollout is set as "Automatic by Cato", will the client version get updated or not. If not, then will this create issue in upgrading the version to get benefit and manual upgrade is time consuming
