Well according to someone here. <br />

He said that it will be helpful that the proxmox machines ping the multi-cast address: <br />

Hello Experts, <br />
<br />
There is a weird situation with proxmox.<br />
<br />
I cannot ping from proxmox a server in the network yet the rest of network I can. <br />
<br />
The actual virtual machine can ping the server. <br />
<br />
The server we want to ping is the primary DNS server (if it makes a difference). <br />
<br />
No idea where to begin troubleshooting. <br />

Hello Experts, 

There is a weird situation with proxmox.

I cannot ping from proxmox a server in the network yet the rest of network I can. 

The actual virtual machine can ping the server. 

The server we want to ping is the primary DNS server (if it makes a difference). 

No idea where to begin troubleshooting. 

Regards,

Proxmox cannot ping a server in the network yet the rest of that network

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Virtualization

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

Network Operations includes asset management, help-desk supervision, security and user policies, infrastructure administration and anything else that affects the operation of your network. Discussions will include those of best practices in platforms, configurations, performance, security and accounting.

Network Operations

Network security consists of the policies adopted to prevent and monitor authorized access, misuse, modification, or denial of a computer network and network-accessible resources. Network security involves the authorization of access to data in a network, and covers a variety of computer networks; conducting transactions and communications among businesses, government agencies and individuals. Networks can be private, such as within a company, and others which might be open to public access.

Network Security

Networking software modules are interfaced with a framework implemented on the machine's operating system that implements the networking functionality of the operating system. The best known frameworks are the TCP/IP model and the OSI model. Systems typically do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol family or protocol suite.[9] Some of the best known protocol suites include: IPX/SPX, X.25, AX.25, AppleTalk and TCP/IP. Other protocols indirectly related to networking include the hypertext transfer protocol (HTTP) and its related technologies, Dynamic Host Configuration Protocol (DHCP), Domain Name Server (DNS) and other Internet protocols.
