As you already said, you could use a site-to-site vpn. I don't know your 
network, but if a non-openvpn site-to-site vpn would works, I guess you could 
also use one openvpn instance on both sides to establish a site-to-site 
connection.

Or you could nat multiple ports to multiple clients. For example: your offical 
IP is 123.123.123.123. your internal clients have the IPs 192.168.0.1, 
192.168.0.2, 192.168.0.3, 192.168.0.4. You then could nat 
123.123.123.123:9111 to 192.168.0.1, 
123.123.123.123:9112 to 192.168.0.2, 
123.123.123.123:9113 to 192.168.0.3, 
123.123.123.123:9114 to 192.168.0.4
...

Personally I would definitely recommend a site-to-site vpn!

Kind regards

Julian

Betreff: [Bacula-users] FD behind NAT

Forgive me if this has been asked and answered.

I have a client (FD) behind NAT and I am look for ways to initiate backup jobs 
from the server without port forwarding on the client side.

I have read numerous articles of how to resolve issues with the server (DIR/SD) 
being behind NAT but to me this is easy. I have even looked over the "Dealing 
with Firewalls" section of the manual. In order for bacula to work Dir must be 
able to contact FD to tell it to start the backup. Port forwarding is not an 
option as we have numerous clients, Linux and Windows, behind NAT and we cannot 
assign an external IP to each internal FD. To me this means I have to have a 
site-to-site VPN tunnel or clients each running OpenVPN for example.

I am hoping somone can point me towards something I missed.
