<pre class="moz-quote-pre" wrap="">Hi Paul,
If you have a conn:
conn njh
type=tunnel
authby=secret
auto=ignore
#auto=start
left=12345.example.com
leftsourceip=172.17.2.1
leftsubnet=172.17.2.0/24
right=159.203.19.178
rightsourceip=10.137.48.60
rightsubnet=10.137.48.60/16
dpdaction=restart
dpdtimeout=120
dpddelay=30
Then load it with "ipsec auto --add njh" you get the following:
[root@server ~]# ipsec auto --add njh
000 failed to convert '12345.example.com' at load time: not a numeric IPv4
address and name lookup failed (no validation performed)
002 added connection description "njh"
It seems to be because the first subdomain is numeric. It seems to assume that
if the first part of the FQDN is numeric then the parameter is going to be an IP
address and not an FQDN. In this case 12345 can never be an FQDN, but you get
the same issue 123. I have a feeling some cleverer interpretation is needed of
this type of parameter.
I have tested this with a valid FQDN like this but can't publish it,
unfortunately. You can test it on *.poweredbyclear.com as it has wildcard
resolution back to the primary A record.
This is with libreswan-3.25-9.1.el7_8.x86_64.
Regards,
Nick

<p>man ipsec.confm section IDENTITY PARSING</p>
<p> The type and binary encoding of identity strings
specified in leftid are detected as follows:<br>
<br>
· If the string value contains an equal sign (=) it
is assumed to be a Distinguished Name, with RDNs separated by
commas (,) or slashes (/ - the string must<br>
start with a slash to use this syntax). An attempt
is made to create a binary ASN.1 encoding from this string. If
that fails the type is set to KEY_ID with<br>
the literal string value adopted as encoding.<br>
<br>
· If the string value contains an @ the type depends
on the position of that character:<br>
<br>
· If the string begins with @# the type is
set to KEY_ID and the string following that prefix is assumed to
be the hex-encoded binary value of the<br>
identity.<br>
<br>
· If the string begins with @@ the type is
set to USER_FQDN and the encoding is the literal string after
that prefix.<br>
<br>
· If the string begins with @ the type is set
to FQDN and the encoding is the literal string after that
prefix.<br>
<br>
· All remaining strings containing an @ are
assumed to be of type USER_FQDN/RFC822 with the literal string
value as encoding.<br>
<br>
· If the value does not contain any @ or =
characters it is parsed as follows:<br>
<br>
· If the value is an empty string, or equals
%any[6], 0.0.0.0, ::, or * the type is set to ID_ANY, which
matches any other identity.<br>
<br>
· If the value contains a colon (:) it is
assumed to be an IPv6 address. But if parsing the address and
converting it to its binary encoding fails the<br>
type is set to KEY_ID and the encoding is
the literal value.<br>
<br>
· For all other strings an attempt at parsing
them as IPv4 addresses is made. If that fails the type is set to
FQDN and the literal value is adopted<br>
as encoding (this is where domain names and
simple names end up).</p>
