This is the output of Monowall ifconfig -a $ ifconfig -a sis0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 options=8<VLAN_MTU> inet 192.168.3.1 netmask 0xffffff00 broadcast 192.168.3.255 inet6 fe80::200:24ff:fec0:7d80%sis0 prefixlen 64 scopeid 0x1 inet6 2001:b18:403b:1::1 prefixlen 64 ether 00:00:24:c0:7d:80 media: Ethernet autoselect (100baseTX <full-duplex>) status: active sis1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 options=8<VLAN_MTU> inet6 fe80::200:24ff:fec0:7d81%sis1 prefixlen 64 scopeid 0x2 ether 00:00:24:c0:7d:81 media: Ethernet autoselect (100baseTX <full-duplex>) status: active sis2: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 options=8<VLAN_MTU> inet 192.168.0.1 netmask 0xffffff00 broadcast 192.168.0.255 inet6 fe80::200:24ff:fec0:7d82%sis2 prefixlen 64 scopeid 0x3 inet6 2001:b18:403b:2::1 prefixlen 64 ether 00:00:24:c0:7d:82 media: Ethernet autoselect (100baseTX <full-duplex>) status: active enc0: flags=41<UP,RUNNING> mtu 1536 lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384 inet 127.0.0.1 netmask 0xff000000 inet6 ::1 prefixlen 128 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x5 ng0: flags=88d1<UP,POINTOPOINT,RUNNING,NOARP,SIMPLEX,MULTICAST> mtu 1492 inet6 fe80::200:24ff:fec0:7d80%ng0 prefixlen 64 scopeid 0x6 inet 79.159.5.41 --> 192.168.153.1 netmask 0xffffffff ng1: flags=8890<POINTOPOINT,NOARP,SIMPLEX,MULTICAST> mtu 1500 ng2: flags=8890<POINTOPOINT,NOARP,SIMPLEX,MULTICAST> mtu 1500 ng3: flags=8890<POINTOPOINT,NOARP,SIMPLEX,MULTICAST> mtu 1500 ng4: flags=8890<POINTOPOINT,NOARP,SIMPLEX,MULTICAST> mtu 1500 ng5: flags=8890<POINTOPOINT,NOARP,SIMPLEX,MULTICAST> mtu 1500 ng6: flags=8890<POINTOPOINT,NOARP,SIMPLEX,MULTICAST> mtu 1500 ng7: flags=8890<POINTOPOINT,NOARP,SIMPLEX,MULTICAST> mtu 1500 ng8: flags=8890<POINTOPOINT,NOARP,SIMPLEX,MULTICAST> mtu 1500 ng9: flags=8890<POINTOPOINT,NOARP,SIMPLEX,MULTICAST> mtu 1500 ng10: flags=8890<POINTOPOINT,NOARP,SIMPLEX,MULTICAST> mtu 1500 ng11: flags=8890<POINTOPOINT,NOARP,SIMPLEX,MULTICAST> mtu 1500 ng12: flags=8890<POINTOPOINT,NOARP,SIMPLEX,MULTICAST> mtu 1500 ng13: flags=8890<POINTOPOINT,NOARP,SIMPLEX,MULTICAST> mtu 1500 ng14: flags=8890<POINTOPOINT,NOARP,SIMPLEX,MULTICAST> mtu 1500 ng15: flags=8890<POINTOPOINT,NOARP,SIMPLEX,MULTICAST> mtu 1500 ng16: flags=8890<POINTOPOINT,NOARP,SIMPLEX,MULTICAST> mtu 1500 gif0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1280 tunnel inet 79.159.5.41 --> 82.102.0.131 inet6 fe80::200:24ff:fec0:7d80%gif0 prefixlen 64 scopeid 0x17 inet6 2001:b18:2000:80::2 --> 2001:b18:2000:80::1 prefixlen 128
