As a highly versatile IT professional with advanced networking skills, including extensive experience managing MikroTik appliances, I am confident in my ability to flawlessly transfer your current MikroTik RB4011Igs+ configuration to a CHR. Having worked with hyperv VMs and 4 port NIC setups like you have described, I am confident I can conduct this task accurately within the given timeframe.
Moreover, what sets me apart is my deep understanding of CloudFlare technology, which is crucial for bypassing ISP blocked ports such as 80 and 443 - something we prefer doing via CloudFlare. This will not only ensure smooth operation for your network but also secure transmission of data through ports 80 and 443 to CHR on 8080 and 4443 respectively.
Additionally, my expansive proficiency in cloud computing platforms like AWS, Azure, and Google Cloud; server operating systems such as Windows Server and Linux; web servers including IIS, Apache, Nginx and more is an added advantage for your project. It proves my capacity to handle complex configurations like the one required - transferring DHCP server operations from your RB4011Igs+ to the CHR on a hyper-v VM. With me at the helm of your project, expect not just competence but also professionalism and diligence in executing this task to perfection.
