multicast config

Post by adminnoob » Fri Jan 06, 2012 11:07 pm

I'm trying to figure out if Openvpn is right for me.

Can a config file be conjured up that reroutes multicast packets destined for those that subscribe to 227.200.20.2 and sends them to those that are subscribed to 228.200.20.2?

LinuxBox1 ----> 227.200.20.2 ----> LinuxBox2 [227.200.20.2->228.200.20.2]LinuxBox2----->228.200.20.2---->Windows7Box

I don't have a specific need for it other than this. I was trying to use mrouted, but I couldn't find any useful config files to help me out.

Even if this isn't the right program for me, I would appreciate a boost in the right direction. It doesn't even need to change it from 227 to 228, if it would just pass it along that would be great.

Netmask'ing is not related to OpenVPN. See the iptables' option netmask.

This is that I found in wiki

"The routing prefix is expressed in CIDR notation. It is written as the first address of a network, followed by a slash character (/), followed by the bit-length of the prefix. For example, 192.168.1.0/24 is the prefix of the Internet Protocol Version 4 network starting at the given address, having 24 bits allocated for the network prefix, and the remaining 8 bits reserved for host addressing. The IPv6 address specification 2001:db8::/32 is a large network for 296 hosts, having a 32-bit routing prefix. In IPv4 the routing prefix is also specified in the form of the subnet mask, which is expressed in quad-dotted decimal representation like an address. For example, 255.255.255.0 is the network mask for the 192.168.1.0/24 prefix."
