Netextender is sonicwall’s client for SSL VPN connection. Here we explains how to configure ssl vpn on sonicwall and configure users for connection to the firewall using netextender. Before we setup users or install client, we have to make sure SSL VPN is enabled on WAN interface. If you have already done this Skip to the next step. Note: All guides are based on new interface
1. ENABLE SSL VPN ON WAN ZONE

Note down the SSL VPN port and User Domain. We need these to setup the client later. You may change this is necessary but its recommended to keep it default unless really need a change.
3. CONFIGURE SSLVPN CLIENT SETTINGS
Connectivity–>SSL VPN –> Client settings
Edit Default Device Profile
ON SETTINGS tab
Choose Zone IPV4 : SSL VPN
Under Network IP address V4: Create a new network as IP RANGE & under SSL VPN ZONE ,but give it a unique IP range in same network of your LAN network. Make sure , you dont conflict with any DHCP or Static IP range
Under CLIENT ROUTES , Choose LAN Subnets and/or any other network/device this VPN users may need access to . If they need access to particular server only, you can limit this to that server only.
Adjust the CLIENT SETTINGS tab as required. We would recommend, the below settings though
Given these are done perfectly, You are ready to add users and setup the Netextender which is explained in this section.
