VPN, SSH and port forwarding

Iam7of9

Hi all.
Please help me with this problem.
I have a virtualbox lubuntu (15.04) machine, connecting out via vpn (privateinternetaccess).
(The VM is set up with a bridged adapter network. The box has its own IP.)
When I ssh from the local lan to this machine's ip address (with the vpn connected and active) everything works well.
When I try to come via the adsl/router (which is set up to do port forwarding to this machine) it doesn't connect when the vpn is connected. When I disconnect the vpn, all is good, and I can connect from my house.

Why can I ssh into this machine from the local lan and not from outside (via the forward port)
There are a few virtual machines running (all without vpn's) and they also connect through the forward ports?
The iptables on the machine is not changed from default.

Please help me to figure/sort this out.
Regards

this is normal because your ssh responses return via the vpn not via your direct internet line,
do avoid this you will need to configure policy based routing on your server,
search the forum since there are many similar topics...
