Coming two and a half months after the previous point release, IPFire 2.19 Core Update 110 is here to implement support for on-demand IPsec (Internet Protocol Security) VPNs (Virtual Private Networks), which might just come in handy to those who deal with a huge amount of IPsec net-to-net connections on their infrastructures. IPFire 2.19 Core Update 110 also adds an extra layer of performance improvements to the built-in Unbound DNS resolver, which is now capable of assigning additional memory to keep a larger DNS cache, and allows for more concurrent queries. This could be very useful in large networks when handling a burst of DNS queries.
