+  There is a problem with the code used from ports (at least for me it was).
+  If you'll get disconnected right after connection, go to http://www.shapeshifter.se/code/hso/ and download/install the code manually.
+  It's pretty trivial so no problems with it.
 **Firewalling**
   ipfw list
+**Firewalling IPv6**
+Below some rules of implementing firewall in FreeBSD. //Using IPFW (please compile your kernel, if it’s not supported).// It’s easy as IPv4.
+<code>
+# Simple Firewall :
+(allow network 2404:170::/32 to any host)
+ip6fw add 100 allow all from 2404:170::/32 to any in via fxp0
+(allow network 2001:dc6::/32 to any host)
+ip6fw add 200 allow all from 2001:dc6::/32 to any in via fxp0
+(allow all ipv6 to host 2404:170:ee02::10)
+ip6fw add 300 allow all from :: to 2404:170:ee02:ee02::10 in via fxp0
+(deny other all traffic).
+ip6fw add 1000 deny all from any to any in via fxp0
+</code>
+**FreeBSD GRE tunnels**

+**Manual IPv6 configuration**
+   ifconfig rl0 inet6 2001:470:1f01:115::4 prefixlen 64  # add address
+   ifconfig rl0 inet6 2001:470:1f01:115::4 delete        # remove address
+   route -n add -inet6 default 2001:470:1f01:115::1      # default route
 ===== NetBSD =====
+**Basic config:**
+   ifconfig tlp0 inet6 2001:470:1f01:115::8 prefixlen 64  # add address
+   ifconfig tlp0 inet6 2001:470:1f01:115::8 delete        # remove address
+   route add -inet6 default default_ip6_gateway_addr      # default route
+**Setting up an IPv6-over-IPv4 tunnel:**
+   ifconfig gif0 create
+   ifconfig gif0 tunnel local_ip4_addr remove_ip4_addr
+   ifconfig gif0 inet6 local_ip6_addr remote_ip6_addr prefixlen /128
