USB-based deployment simplifies the deployment process. It reduces the deployment costs and relieves users from software commissioning. USB-based deployment allows you to configure or upgrade devices using a USB flash drive. Instead of having to visit all remote sites to commission those installed devices, it’s enought to prepare necessary files and let onsite personnel finish the deployment process easily.
Detailed information about USB-based deployment you can find exploring HuaweiAR router documentation.
I believe that education is key to personal and professional growth. And I’m excited to bring that same commitment to this Huawei HCIA course on Udemy. Join me as we explore the fascinating world of networking together! Whether you’re just starting out or looking to advance your skills, this course is designed to provide you with practical insights and real-world applications. Let’s connect and elevate your networking knowledge!
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 # nat address-group PUBLIC_OUT 2 mode no-pat global route enable section 0 6.6.6.1 6.6.6.1 # security-policy rule name PUBLIC_OUT source-zone dmz destination-zone untrust source-address 10.0.100.0 mask 255.255.255.252 action permit rule name PUBLIC_IN source-zone untrust destination-zone dmz source-address 1.1.1.1 mask 255.255.255.255 destination-address 10.0.100.0 mask 255.255.255.252 action permit # nat-policy rule name PUBLIC_OUT source-zone dmz destination-zone untrust source-address 10.0.100.0 mask 255.255.255.252 action source-nat address-group PUBLIC_OUT
If you, for some reason, cannot use easy-ip NAT, you can use source NAT with NAT address pool. Depending on how many public IP addresses you have got, you can configure no-PAT option, when only IP address is translated or you can set PAT, in other words NAT with port translation to assure LAN users accessing Internet. Details in the video 😉

A short video describing EASY-IP source NAT on Huawei’s USG firewall to assure that our intranet users can acccess the Internet.
The easy-ip is the easiest way to translate private IP addresses on your local area network when you have only one public IP address or the public IP address is assigned dynamically.
