How to build a branch network on FreeBSD?

Question

FreeBSD

Good afternoon everyone.
The question is.
At work, a branch has appeared that needs to be connected to our network. in both branches there are gateways on Freebsd 10.3
In the head office there is MPD5 and earlier people from the branch connected from each workstation to the server, now there is a task to raise the channel directly between the fryuhas so that users do not make the connection themselves anymore.
The question, or rather the plug, arose with how to implement this, I found articles and discussions on the Internet, but did not understand how to organize it correctly.
in the network there were two options to raise mdp5 in the branch and already configure pptp_client there or raise pptp_client from ports
I tried to do it as in the article site but this option did not work (
and most importantly, after setting up, it is not very clear which command to run to connect the VPN on the branch server.
People who set up such a bunch give advice on how to do it right ....
Thanks in advance

Answer 1

The forum on the lissaya site is a treasure trove of FreeBSD knowledge

Answer 2

I would advise you on OpenVpn to raise connections between the server and the branch

Answer 3

When I still had FreeBSD, I picked up racoon. Now, thank God, strongswan has appeared in FreeBSD - if you need to build a network-to-network connection, you can do it on it. Back in the "System Administrator" there was a whole series of articles on the topic "Building corporate VPNs on this, on this ..."

Answer 4

united 2 offices using ipsec-tools (a-la racoon) + gif interfaces. On both sides there was a fry.
Not so long ago, on my side, I changed freu to genta, on the side where freu did not even notice the change))). It is possible without ipsec, stupidly with gifs, but encryption was needed

Answer 5

On what ports it is necessary to climb in a neighboring network? Maybe an SSh tunnel would work?
