v4 to pop works, v6 doesn't

I'm trying to create a AYIYA tunnel T62329 for a research group of the University of Antwerp. bebru02 looks like the best option for a POP since the UA is part of BELNET.
I'm able to send IPv4 traffic to the POP from the system that I'm trying to connect, it runs aiccu 20070115-11, installed from the standard package of Ubuntu 10.04.3 server.
I'm 99% sure UDP/5072 is not blocked, i'm waiting on a response from the UA network service for that last 1%.
Aiccu seems to run fine (ifconfig sixxs):
sixxs Link encap:IPv6-in-IPv4
inet6 addr: fe80::8f81:8372/128 Scope:Link
inet6 addr: 2001:6a8:200:32::2/64 Scope:Global
UP POINTOPOINT RUNNING NOARP MTU:1280 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:8 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:0 (0.0 B) TX bytes:832 (832.0 B)
TX bytes increases when i use 'ping6' as expected, RX doesn't
There is no v6 firewall
routes seem fine (route -A inet6):

"ping6 2001:6a8:200:32::2" (myself) works, "ping6 2001:6a8:200:32::1" (pop) doesn't, "ping6 2a00:1450:400c:c01::6a" (google) also doesn't.
"aiccu test" does nothing, it just stops after a couple of seconds with returncode 0.
If i give the real networkcard a ipv6 and another system in the lan also then they can also ping each other.
I'm NGB2-SIXXS , my e-mail is nikolas.garofil@ua.ac.be (and the one listed in my userinfo), the server i want to connect runs at 143.129.131.114
This is what i get after starting aiccu:
Tunnel Information for T62329:
POP Id : bebru02
IPv6 Local : 2001:6a8:200:32::2/64
IPv6 Remote : 2001:6a8:200:32::1/64
Tunnel Type : ayiya
Adminstate : enabled
Userstate : enabled
The aiccu config (comments, passwords and empty lines removed):
username NGB2-SIXXS
protocol tic
server tic.sixxs.net
ipv6_interface sixxs
tunnel_id T62329
verbose true
daemonize true
automatic true
requiretls false
Any ideas ?

As such, no valid packet was received for quite a while. Check those filters in your network.
It would be useful to include traceroutes etc btw.

it used to be a tunnel that i created for myself for different testing purposes (personal instead of workrelated) but i stopped using it so it seemed like a good idea to use this one instead of creating a new one, thats why the last beat is so long ago

i think i made a mistake when i told you that the firewall of the university wasnt blocking the ports, i did some tests with nmap and now i'am actually pretty sure that it is blocked so thats probably the problem.
I am meeting the persons responsible for the firewall monday, i will tell you if everything works after they open UDP/5072 and TCP/3874
