Note:
- Once WWAN is enabled from Cyberoam Telnet Console, a default interface named WWAN1 is created with the default IP address 0.0.0.0 and is the member of the WAN zone.
- As WWAN interface is a member of WAN zone:
o All the services enabled for the WAN zone from the Appliance Access page are automatically applicable on WWAN1 connection too.
o All the firewall rules applied on WAN zone will be applied on WWAN interface.
- A default host named ##WWAN1 is created and firewall rule and VPN policies can be created for the default host.
- WWAN1 gateway is added as Backup gateway.
- When the Wireless WAN is disabled from Cyberoam Telnet Console, Wireless WAN menu, default host ##WWAN1and WWAN gateway options will be removed from Web Admin Console.
Step 3: Connect to the Internet
Go to Network à Wireless WAN à Status and click Connect to connect to the Internet using plugged-in modem.
Note:
- High Availability (HA) is not supported when Wireless WAN is enabled.
- DHCP Server configuration is not supported for WWAN interface.
- If Cyberoam backup is taken from a system where WWAN is enabled and restored on a system where it is not enabled, WWAN configuration would still be visible.
