The openconnect server expects to be configured using the uci interface.

To setup a server the provides access to LAN with network address
10.100.2.0/255.255.255.0 using the VPN address range
10.100.3.0/255.255.255.0 add the following to /etc/config/ocserv:

-----------------------------------------------------------------
config ocserv 'config'
	option port '4443'
	option dpd '120'
	option max_clients '8'
	option max_same '2'
	option netmask '255.255.255.0'
	option ipaddr '10.100.3.0'
	option auth 'plain'
	option zone 'lan'
	option fwport '4443'
	option enable '1'

config dns
	option ip '10.100.2.1'

config routes
	option ip '10.100.2.0'
	option netmask '255.255.255.0'

config ocservusers
	option name 'test'
	option password '$5$unl8uKAGNsdTh9zm$PnUHEGhDc5VHbFE2EfWwW38Bub6Y6EZ5hrFwZE1r2F1'

-----------------------------------------------------------------

This configuration also adds the user "test" with password "test". The
password is specified in the crypt(3) format.

The server can be enabled and started using:
# /etc/init.d/ocserv enable
# /etc/init.d/ocserv start



There is a luci plugin to allow configuring the server from
the web environment; see the package luci-app-ocserv.
