Centos7 router not function properly

Hi, I'll be pleased to work on this project for you. Let me introduce myself. I'm a CCIE certified network engineer with 6+ years of experience in configuring, troubleshooting and maintaining complex networks for large enterprises. My most recent project is a network comprising of over 2000 routers along with 1 main data center and 1 disaster recovery site. Do get me on board and I assure you that you will not be disappointed.

Hello, this is raza , I am system and network admin with more than 10 year experience . I can help you regarding this project.

Good day! I am certified network engineer MTCTCE/MTCNA having over 10 years of experience in configuring, maintaining and troubleshooting of enterprise network devices, firewalls and Linux servers. I can configure your VirtualBox and CentOS qualitatively, because I have a lot of experience with Linux servers and VirtualBox (including different network modes). You can't use same subnets on the bridge interface and on the interface with internal network mode. What real subnet on your host's NIC? The bridge interface and host's interface must have a same subnet, but not the interface with internal network mode. I can tell You more in the chat.

Dear Employer, I can help you with your CentOS implementation based on your requirements. At the end you will have working internet on hosts connected to your internal card. If you have any questions, don't hesitate to contact me.

Hello I am a system and network administrator, with more than 10 years of experience. I worked with different services and servers, particularly, designing of a local data center, management of local and remote sites, and cloud environments. The above-mentioned experience includes work with virtualization technologies, mostly based on VMWare products, cloud services such as AWS, DigitalOcean, and etc. I have proven knowledge of networking and security, thanks to the work experience and Cisco training sessions I participated. The short list of the servers and services include but are not limited to: Web Server (Apache, Nginx, IIS), Mail Server (Postfix, Exim, PowerMTA), DNS Server (BIND, Unbound, MS DNS), Firewalls (Iptables, PFSense, etc.), basic scripting (BASH) etc. If I understand your issue correctly, the problem is with VirtualBox. You need to have ICMP forwarding from VM to the Physical machine. However, as far as I remember, VirtualBox allows only IP level forwarding. Thank you for considering my application. Regards Eduard

yes i can fix this, i am red hat certified linux admin and can fix this issue............................................................

Hello, I was doing a lot of routing with CentOS-es. I'd like to take a look at your setup via ssh, the routing tables and the firewall nat settings. Best, Istvan

I ran into this problem several times. I think I know what is missing there. Relevant Skills and Experience I worked in a firm configuring and managing linux routers.
