I would like to remind you all that until the end of October you can buy my course, on the UDEMY platform, at a special price. It won’t be cheaper anymore 🙂
Please be invited to watch a trailer of this course.
If you want to buy this course just click on Huawei HCIA Datacom Course.
I look forward to seeing you on the inside!
It took some time but I finally managed to publish my first course on Udemy last week. This course covers Huawei technologies and prepares you to pass the Huawei H12-811 exam. I am confident that it helps you get the HCIA Datacom certificate. This course covers some theory but you can also find many labs that you need to compete. Buying this course you can start your adventure with Huawei devices and Huawei technologies. Whether you are new to computer networking or have CCNA level knowledge, this course is for you. So do not hesitate, invest in yourself, this course will be a good choice and perhaps the beginning of your path towards HCIE.
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 😉

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.
