Function Write-SSLVPNConfig { <# .Description Creates a Fortigate Config Script for a simple SSL Client VPN implementation. .Parameter CommaSeperatedDNSSuffixes DNS Suffixes for Split DNS .Parameter DNofParentOU Distinguished Name of the Top Level OU for the authenticating Domain .Parameter DNSServerIP IPv4 address of the DNS server used by the SSLVPN clients .Parameter InternalLanSubnetMask Subnet mask of the LANIP to be accessed ex: 255.255.255.0 .Parameter InternalLanIP IP Address thats matches the Host Minimum for the Subnet .Parameter LanInterfaceName Name of the LAN interface containing the to be accessed Subnet .Parameter LDAPServerFriendlyName Friendly Name for referencing the LDAP authentication server .Parameter ServiceAccountPassword Password of the Authenticating service account .Parameter ServiceAccountsAMAccountName sAMAccountName for the service account that will authenticate to the LDAP server.
