So, add the necessary rules, both on the INSIDE and DMZ interfaces to allow traffic to and from your LAN to and from the netextender client IP subnet.
You still have to allow that netextender client subnet access to your LAN in your PIX rules. If your LAN's default gateway is a core switch inside of your LAN, add a route there to send the traffic for the netextender's subnet to the PIX inside interface, then also add the route in the PIX to route it to the SSL VPN appliance in the DMZ.
Netextender will present you a pop up where the firewall and users details are to be filled. We highly recommend it to check both Home & Work network and click allow. Once the setup in installed, you may receive a firewall allowance request. (recommended) Enable Restrict to Strong Ciphers Only. Alternatively you could request assistance for setup file here. Go to CONFIGURATION > Configuration Tree > Box > Virtual Servers > your virtual server > Assigned Services > VPN-Service > SSL-VPN. So, if your LAN's default gateway is your PIX, you'll just have to add a route in your PIX for the 192.168.20.0/24 subnet with a gateway IP of your SSL VPN appliance (.x in your DMZ). Enable the SSL VPN service and add the listening IP addresses.
How to use sonicwall netextender how to#
Now, you have to tell your PIX and your LAN how to get to that netextender client range (192.168.20.0 in this case). Now, you want to configure your netextender IP range as something OFF your LAN, probably another .x/24 subnet that's different than your DMZ subnet, and I'd recommend making it something high, like 192.168.20.0/24 as to prevent interference for home users that are using default LAN IP subnets like 192.168.1.0's and 192.168.0.0's. So, it sounds like you've assigned the Sonicwall a DMZ IP of .x and you're NAT-ing your SSL traffic to it from a public IP for the virtual office connection. It sounds like you're on the right track. Most importantly, enabling multi-factor authentication on all SonicWall products.Hi Ryan. Naturally, this will take some time, so owners of the affected products are urged to read the security notice issued by the firm today and follow the instructions on how to apply effective mitigations. The company has identified the zero-days used by the hackers and is in the process of addressing them with a fixing patch. However, this hasn’t been officially confirmed by SonicWall, so we’re reproducing it with prudence.
How to use sonicwall netextender code#
As for what the hackers managed to access before they were eventually thwarted, the main thing was source code hosted on the company’s GitLab repository. As the firm explained, the infiltrators appear to be highly sophisticated threat actors as they leveraged zero-day vulnerabilities in the ‘NetExtender VPN’ client and the ‘Secure Mobile Access’ made by the company itself and used internally by the employees.Īccording to reports that surfaced on The Hacker News, SonicWall has had some notable outage events earlier in the week, a result of the aforementioned hack. Once this connection is set up, users will have the same rights and access possibilities as if they are connected on the local network. ‘SonicWall’, the American internet appliance and award-winning network security company, has announced the occurrence of a coordinated attack against its internal systems. SonicWall NetExtender is a SSL VPN (Secure Sockets Layer Virtual Private Network) that allows remote users to establish a secure connection to the remote network.
