Hi all
Kindly refer to this:
As you can see I wish to configure the 450g to act as a firewall and also I wish to make it a VPN server. How can I configure it in this manner and to be as secure as possible?
Thanks for your help!
I do not see any problems to use RouterBOARD for VPN server, just choose one of the supported servers,

Use /ip firewall filter for the firewall.
Firewall configuration depends on the way, you want to secure the router.
Use chain=input to secure access to it,
- allow only IP address you will use for router management;
- allow VPN client address and used port/protocol;
- drop everything else.
