Use the other box to set up a pfSense firewall/gateway.  pfSense is a fantastic FreeBSD-based firewall distro and has configurable options for PPTP, IPSec, and OpenVPN VPNs built in.

I would install pfSense, enable OpenVPN, and configure it to authenticate using either FreeRadius or LDAP against your internal AD.  Lots of guidance for doing this is available on the forums.

VPN server to access Samba4
I'm going on my honeymoon to Thailand, Cambodia and Vietnam in June for 4 weeks.

I'll bring my Canon t3i + 15-55mm and a 55-250mm lens.

This will be my first travel like this and I definitely want to take some awesome pictures.

I don't have a Flash and I want to buy a Canon Speedlite 430EX when the time comes.

The question is... Is it Worth it to buy this flash for this kind of travel?
