IPsec ERROR: Could not find phase 1

  • C

    Hello everybody,

    I have a problem in the IPsec.
    My IP address is 2a00: 61e0: xxxx: xxxx :: and pfSense can not create the config file. It is due to the two colon at the end of the IP address.

    Get pfSense a full IP address to the end.
    e.g .:
    2A00: 61e0: 47e1: 74A2: 89b3: 54f3: dd6b: 7823
    Is not there a problem.

    I have tested it three times.
    The full length of the IP address works.
    Not in a short form 2A00: 61e0: xxxx: xxxx ::
    Is this a mistake in pfSense?

    Here are the system log's.

    @chris_6n said in IPsec ERROR: Could not find phase 1:

    IPsec ERROR:

    Hello
    PFSense uses PHP's built-in function Net_IPv6::checkIPv6 to verify that the ipv6 address is valid. If this function returns the value that the address is invalid, then this error is displayed.

    This function returns true if the ipv6 address contains 8 groups of 4 hexadecimal digits (128 bits)

    OK. That's a problem now.
    I thought as much!

    Can I disable or change this feature?

    @chris_6n
    You can try editing the file /etc/inc/vpn.inc and disable address verification
    line 280-283
    but I don't know if Strongswan or PFSense will work correctly after that .
    I recommend saving the original file before editing it

    if (!is_ipaddr($ep)) {
				log_error(sprintf(gettext("IPsec ERROR: Could not find phase 1 source for connection %s. Omitting from configuration file."), $ph1ent['descr']));
				continue;
			}

    you have to do this

    /* if (!is_ipaddr($ep)) {
				log_error(sprintf(gettext("IPsec ERROR: Could not find phase 1 source for connection %s. Omitting from configuration file."), $ph1ent['descr']));
				continue;
			} */

    @Konstanti

    The error message in the system log is no longer available.
    The rest is as before. It did not need success.
    IPSec status is Unknown.

    There must be another IP Check function.
    Who builds something like that?

    Many people in Germany get such ip addresses.
    From German glass fiber.

    I do not see that is_ipaddr() fails when given an address ending in a ::.

    There must be something else going on.

    For instance, you can run the following in Diagnostics > Command Prompt at the bottom:

    $ep = "2A00:61e0:47e1:74A2::";

if (!is_ipaddr($ep)) {
	 echo sprintf(gettext("Invalid IPv6 address: %s"), $ep);
} else {
         echo sprintf(gettext("VALID IPv6 address: %s"), $ep);
}

    And you get: VALID IPv6 address: 2A00:61e0:47e1:74A2::

    Change it to something invalid and it does the expected:

    $ep = "2A00:61e0:47e1:74A2::g";

if (!is_ipaddr($ep)) {
	 echo sprintf(gettext("Invalid IPv6 address: %s"), $ep);
} else {
         echo sprintf(gettext("VALID IPv6 address: %s"), $ep);
}

    Invalid IPv6 address: 2A00:61e0:47e1:74A2::g

    @Derelict

    Okay, I have tested it.
    The result with my IP address is VALID IPv6 address.

    Can it be that behind the IP address is a hidden blank?
    In the Dashboard Interfaces behind my address is also a hidden blank!

    Screenshot_20191029_101321.png

    In the Status / Interfaces there is no hidden blank behind it.
