Inbound TCP is closed with a few exceptions:
- Port 22 (SSH) is open from the UiO network
- Port 80 (HTTP) is open from the UiO network
UDP is generally open with a few exceptions:
- Windows neighbourhood ports (135-139, 445) is filtered.
- A few ports below 1024 (SNMP etc)
- Ports 31337 and 32771.
IPv4 and IPv6 access lists are pretty much similar.
VPN protocols (AH/ESP/GRE) are open, except to the UiO network.
