Clearly, it's not cheap.
2.5gb and 10gb everywhere now.
QNAP is solid and the support is responsive and French.
VPN and site-to-site server functions, Multi-Wan, firewall, DHCP etc...
The kind of box that you forget afterwards, it works without a problem.
One small comment: it heats up a little but not excessively, so you'll need to think about placing it in a well-ventilated place or in a ventilated cupboard.
Taken with payment in 3 instalments. Thanks LDLC
