# Known bug: Modules not unloaded when STOP
#

# Nätförklaringar:
#       2001:6f0:4::/48      - Nät routat hit
#       2001:6f0:4::/64      - Nät hemma på eth1 interfacet
#       2001:6f0:4:1::/64    - Subnet i Vasteras
#       2001:6f0:4:ffff::/64 - Länknät mellan Vasteras och min brandvägg
#       2001:6f0:6:2::/64    - Länknät mellan ipv6rtr.t4.sto och min brandvägg
