A firewall protects the StudNet against attacks from the Internet. The configuration of the firewall is not very restrictive. The firewall protects against many simple attacks from outside, but not against all. Especially it does not protect against attacks from other residents targeting your own computer!

For an outgoing connection all ports are open with exception of filter rules listed below.

The following ports are open for incoming connections:

  • FTP (port 20/21 UDP/TCP)
  • SSH (port 22 TCP)
  • HTTP (port 80 TCP)
  • IDENT (port 113 TCP)
  • HTTPS (port 443 TCP)
  • IPSec (port 500 UDP, IP protocols 50, 51)
  • ports 50000-50010 TCP
  • ports 50000-50010 UDP

Please be aware that we cannot guarantee assignment of a public IPv4 ip anymore. IPv6 is available network wide.
