Help on StrongSwan IPSEC configuration

I need to establish a L2TP over IPSEC vpn connection to another server. I'm using ubuntu 16.04.



Also I installed StrongSwan and xl2tp plus configurations from this tutorial



https://codediary.net/posts/l2tp-ipsec-vpn-on-ubuntu-16-04/



When I run IPSEC with the command ipsec up myvpn it fails to connect. I guess it's because it needs some custom configurations for IPSEC connection.



Following conditions are needed



IPSEC Phase 1 Proposal----------------------
encryption 3DES Authentication SHA1
encryption AES192 Authentication SHA1
encryption AES256 Authentication MD5
Diffie-Hellman Group 2
Key lifetime (seconds) 86400

IPSEC Phase 2 Proposal----------------------
Local Address 0.0.0.0/0.0.0.0
Remote Address 0.0.0.0/0.0.0.0
encryption 3DES Authentication SHA1
encryption AES192 Authentication SHA1
encryption AES256 Authentication MD5
Key lifetime (seconds) 86400


And here is my current ipsec.conf file



# ipsec.conf - strongSwan IPsec configuration file

# basic configuration

config setup
# strictcrlpolicy=yes
# uniqueids = no

# Add connections here.

# Sample VPN connections

conn %default
ikelifetime=60m
keylife=20m
rekeymargin=3m
keyingtries=1
keyexchange=ikev1
authby=secret
ike=aes128-sha1-modp1024,3des-sha1-modp1024!
esp=aes128-sha1-modp1024,3des-sha1-modp1024!

conn myvpn
keyexchange=ikev1
left=%defaultroute
auto=add
authby=secret
type=transport
leftprotoport=17/%any
rightprotoport=17/1701
right=XXX.XXX.XXX.XXX


Can anyone tell me how to make ipsec.conf file to satisfy mentioned conditions?



Thank you.
