In this example, the FortiGate protects a local network (10.10.111.0/24) that a remote user on an iOS device needs to
securely access over the Internet using a VPN connection. The FortiGate is configured as a dialup VPN server on wan1,

Assigning IP addresses
Once the basic configuration is enabled, you can configure IP address assignment for clients, as well as DNS and WINS
server assignments. Usually you will want to assign IP addresses to clients. The easiest way is to assign addresses from
a specific range, similar to a DHCP server.

2,348 | IPsec VPN
DHCP server
IKE Mode Config can use a remote DHCP server to assign the client IP addresses. Up to eight server addresses can be
selected for either IPv4 or IPv6. The DHCP proxy must be enabled first.
To assign an IP from a DHCP server:

their fully qualified domain names (FQDN). This feature is particularly useful in environments where users access
internal resources over VPN connections. By appending a D... | https://fortinetweb.s3.amazonaws.com/docs.fortinet.com/v2/attachments/3afdbab8-dcdc-11ef-8766-ca4255feedd9/FortiOS-7.6.2-Administration_Guide.pdf |
