Configuring IPv6 on pfSense for Starhub

Posted by crimsonpisang on   0 comments   0 trackback


Starhub has been providing IPV6 network connectivity to its customers for quite some time now. I recently discovered this when I saw that my WAN interface has a valid global unicast IPV6 address. Setting IPV6 on pfSense is quite straight forward. However, I did had to do a lot of Google searches and reading up on IPV6 in order to do so.

IPv6 security myth – IPv6 network/host are too big to scan

An IPv6 /64 allows for up to 18,446,744,073,709,551,616 (about 18.4 Quintillion) host addresses. To take that into perspective, if a computer could scan a billion addresses per second, it would take about 585 years to complete.

Fortunately there are a couple of ways to find all the host without having the need to scan the entire address space.
In IPv6, multicast address were used instead of broadcast. One way is to use multicast group, FF02:: Link Local prefix. When an active device connected to the network, it would joined the FF02::1 multicast group. This group, the All Nodes, is the equivalent to the broadcast address used in IPv4 mainly used for ARP.
Simply by pinging the All node multicast address, we could get a reply for all active nodes on the network in just a few seconds.

A while ago I've recieved my wireless N usb adapter which I've got for about 3 bucks on ebay. Most of the guide I found on the web only shows how to configure WPA which does not work on my WPA2 home network. After some crafty searches, I finally got mine to work.


Fibers and SFPs

It finally arrived in the mail yesterday. I bought an LC to LC multimode fiber off ebay as getting one locally from SLS is a major ripped off.
