Hi Miroslav,
Thank you.
We've made progress. I haven't included the any of the log file as it
is very verbose (24488 lines - for ipsec up, statusall, down). Please
let me know which sections to look at and I'll grab those.
As you can see below the transaction request below seems to be very
laboured but does result in a success statement. Following that I have
tried to test with openl2tp to create the l2tp ppp tunnel. Openl2tp
seems create this tunnel but ifconfig does not show any ppp interfaces.
The lines in the conn left/rightprotoport do not seem to affect the
outcome whether included or not. The charondebug line when uncommented
prevents any output and I suspect that the syntax is wrong there.

Hi Stephen,
Please delete type=transport or change it to type=tunnel.
Also delete rightprotoport and leftprotoport.
If this did not help, please provide again ipsec statusall + enable
logging at higher level as described here
<https://wiki.strongswan.org/projects/strongswan/wiki/LoggerConfiguration>
and provide logfile.
Regards,

You are correct, the syntax error is gone. Sadly, there is not

Hi Stephen,
So I assume there is no longer any syntax error reported.
From logfile I see there is no acceptable traffic selector.
I assume that you have a home PC (Ubuntu) with Strongswan which you
want to connect to the office VPN concentrator with IP 17.11.7.5
running Windows. I suppose VPN concentrator in the office is not
configured to route any traffic towards you home PC's IP address, thus
you will need a virtual IP address assigned to your home PC by the VPN
concentrator. Also I suppose you want to route all traffic via that VPN
once connected.
Then, please try to modify "left=%defaultroute" to
"left=%any" and add "rightsubnet=0.0.0.0/0 <http://0.0.0.0/0>" and
"leftsourceip=%config". You should not specify "leftsubnet", it has
same effect as "leftsubnet=%dynamic".
According to documentation at wiki
<https://wiki.strongswan.org/projects/strongswan/wiki/ConnSection>
configuration directive "left=defaultroute%" was used prior to version
5.0.0, superseded by "left=%any".
leftsubnet=%dynamic (or omitting leftsubnet at all) and
rightsubnet=0.0.0.0/0 <http://0.0.0.0/0> will create your traffic
selector. It says that anything (0.0.0.0/0 <http://0.0.0.0/0>) from
your side will be routed to remote host and that the remote host will
route towards your PC (left==local) a traffic which would fit your
dynamically assigned IP. Should you want to route towards office
network only office-related traffic then change
"rightsubnet=<subnet_used_in_Stephen's_office>".
If that didn't help please can you provide output of 'ipsec
statusall' and also more details about network topology?
Regards,
Miroslav

Hi Miroslav,
Thank you. The conn section as presented below was
copied and pasted from web page for convenience (this stripped the
leading white spaced from the conn section). For the moment the white
spaces are in form of TAB characters. I will test with space
characters and complete this email.
I Apologise for the lack of white spaces in the conn
section of below email. I have now tested with both spaces and tabs,
each producing the same error as below.

Hi Stephen,
I believe the issue might be caused as the "conn"
