[strongSwan] After connection, the external IP address does not change

[Moataz Elmasry]

Hi all,

I just setup strongswan server/client. The connection is established 
successfully, but the external IP address does not change. I thought 
that setting leftsubnet on the client and rightsubnet on the server to 
0.0.0.0/0 forces all traffic to go through the created srongswan 
interface. The server is a
digitalocean instance and the client is my local machine (behind NAT)

Here are my configuration:
Server ipsec.conf:

config setup
         charondebug="cfg 7, esp 4, dmn 4,  mgr 4, ike 3"

conn %default
         ikelifetime=60m
         keylife=20m
         rekeymargin=3m
         keyingtries=1

conn pubkey
         left=myserver.com
         leftsubnet=10.1.0.0/16
         leftfirewall=yes
         leftcert=vpnHostCert.der
         leftauth=pubkey
         leftsendcert=always
         right=%any
         rightsendcert=never
         rightsourceip=10.3.0.0/16
         rightdns=8.8.8.8,2001:4860:4860::8888
         rightauth=eap-md5
         rightsubnet=0.0.0.0/0
         auto=add


And client ipsec.conf

config setup

conn %default
         ikelifetime=60m
         keylife=20m
         rekeymargin=3m
         keyingtries=1

conn pubkey
     keyexchange=ikev2
     left=%defaultroute
     leftsourceip=%config
     leftauth=eap
     leftfirewall=yes
     leftid=carol
     leftsubnet=0.0.0.0/0
     right=myserver.com
     auto=add
     rightauth=pubkey
     rightca="C=DE, O=Contensi, CN=myserver.com
     rightsubnet=10.1.0.0/16
     rightsubnet=0.0.0.0/0

Any idea what am I doing wrong?

Thanks and regards,
