Good afternoon,<\/p>\n
If you want to forward ports to a virtualmachine in VirtualBox you should do this:<\/p>\n
Create an interface “tap”<\/p>\n
#sudo tunctl -u $USER<\/p><\/blockquote>\n
Set the tap address:<\/p>\n
#sudo ip addr add 192.168.0.20\/32 dev tap0
\n# sudo ip link set tap0 up<\/p><\/blockquote>\nEnable Ip Forward<\/p>\n
# sudo sysctl net.ipv4.ip_forward=1<\/p><\/blockquote>\n
Add route:<\/p>\n
#sudo route add -host 192.168.0.150 dev tap0<\/p><\/blockquote>\n
Create nat:<\/p>\n
# sudo iptables –flush
\n#sudo iptables -t nat –flush
\n#sudo iptables -t nat -A POSTROUTING –out-interface eth1 -j MASQUERADE
\n#sudo iptables -A FORWARD –in-interface eth1 -j ACCEPT<\/p><\/blockquote>\nRedirecting port 3333 to 3389:<\/p>\n
#iptables -t nat -A PREROUTING -i eth1 -p tcp -d 192.168.0.100 –dport 3333 -j DNAT –to 192.168.0.150:3389<\/p><\/blockquote>\n
eth1 – Ethernet connected to the router.
\n192.168.0.150 – IP of virtualmachine
\n192.168.0.20 – IP of tap
\n192.168.0.100 – IP of my real machine that receive the connections in 3333<\/p>\nAfter this configure manually your virtualmachine to: <\/p>\n
IP: 192.168.0.150
\nSubnet Mask: 255.255.255.0
\nDefault Gateway: 192.168.0.100<\/p>\nI had problems with ‘–‘ so here is a file with the commands: Forward ports to a virtualmachine.<\/a><\/p>\n
Hope this is usefull,
