Help translating ISP's 6in4 format to Hurricane TunnelBroker format?

I'm trying to setup a IPv6 6in4 tunnel on pfSense by following this guide:

I was able to set it up successfully using a normal Hurricane TunnelBroker tunnel - except the latency is pretty bad here from Sydney, Australia.

So I contacted my ISP, and they said they could also setup a 6in4 tunnel, and to try with that:

This is what the gave me:

• The IPv6 Tunnel Gateway is 2002:3A60:689::1 

• We have allocated your service IPv6 address : 2406:3400:0002:0016::/64 • Your Tunnel IPv6 address : 2002:dce9:a563::/128 • Tunnel configuration

interface Tunnel1 

description 6to4 Tunnel to Exetel ipv6 address :2002:dce9:a563::/128 ipv6 enable tunnel source : 220.233.165.99 tunnel mode ipv6ip 6to4 tunnel path-mtu-discovery

• Route configuration 

ipv6 route 2002::/16 Tunnel1 ipv6 route ::/0 2002:3A60:689::1

This is an example Hurricane network:

IPv6 Tunnel Endpoints Server IPv4 Address:216.218.142.50 Server IPv6 Address:2001:470:1f2c:183::1/64 Client IPv4 Address:115.70.44.175 Client IPv6 Address:2001:470:1f2c:183::2/64 Routed IPv6 Prefixes Routed /64:2001:470:1f2d:183::/64 Routed /48:2600:70ff:c097::/48 [X] DNS Resolvers Anycast IPv6 Caching Nameserver:2001:470:20::2 Anycast IPv4 Caching Nameserver:74.82.42.42 

I'm trying to map the first to the second - for example:

• Server IPv4 and IPv6 Address
• Client IPv4 and IPv6 Address
• Routed /64 and Routed /48 - I see there's a /128 - but it seems like I don't get a a /64 or /48 block? How do I set it up on my pfSense router then?
