Destination NAT on Huawei USG firewall

If you have an FTP server or any other server that you want to make available to internet users, just place the server in DMZ zone of your firewall e.g. Huawei USG and configure a destination NAT. You can then easly restrict IP addresses and protocols that can access your server. And this video is just about that 😉

USG firewall configuration script:

#
interface GigabitEthernet1/0/1
undo shutdown
ip address 10.0.100.1 255.255.255.252
#
interface GigabitEthernet1/0/2
undo shutdown
ip address 5.0.0.2 255.255.255.252
#
firewall zone untrust
set priority 5
add interface GigabitEthernet1/0/2
#
firewall zone dmz
set priority 50
add interface GigabitEthernet1/0/1
#
ip route-static 0.0.0.0 0.0.0.0 5.0.0.1
#
firewall detect ftp
#
nat server 0 protocol tcp global 6.6.6.1 ftp inside 10.0.100.2 ftp unr-route
#

USG firewall configuration script:

#
dhcp enable
#
interface GigabitEthernet1/0/0
undo shutdown
ip address 10.0.0.1 255.255.255.0
service-manage ping permit
dhcp select interface
dhcp server excluded-ip-address 10.0.0.100
dhcp server static-bind ip-address 10.0.0.200 mac-address 5489-98b4-6a79
dhcp server dns-list 10.0.0.100
