I have a number of OpenVPN client sessions set up (where my pfSense
connects to a remote OpenVPN server as a client)
Today I needed to switch one from TCP to UDP and received "An IPv4
protocol was selected, but the selected interface has no IPv4 address".
The interface was properly configured using DHCPv4, and therefore has no
IP address.
After banging my head comparing this VPN with other established/working
VPNs and getting no-where, I started getting through the code to find
this gem:
pfsense /usr/local/www/vpn_openvpn_client.php
} elseif ((stristr($pconfig['protocol'], "6") === false) &&
!get_interface_ip($iv_iface) && ($pconfig['interface'] != "any")) {
$input_errors[] = gettext("An IPv4 protocol was
selected, but the selected interface has no IPv4 address.");
So basically it is currently impossible to create or modify any OpenVPN
client pipe that uses DHCP, as the IP (which isn't known until the
OpenVPN client connects, and is dynamic) must be hard-coded into the
interface before the connection is created.
Commenting out the offending PHP allowed me to save changes and
successfully connect to the VPN.
While this code likely makes sense when setting up and OpenVPN server,
it should not apply when setting up an OpenVPN client.
Am I missing something or is this a bug?
