[Feature Request] Fix For Multicast over OpenVPN

[unmanaged (Gavin Groce)]

OpenVPN treats multicast as broadcast and sends them to all clients. If you have VPN
clients with poor network or CPU performance, you can effectively make
the VPN unusable for them.

Basicly someone has done something to fix the DDOS attack that multicast does to OpenVPN users and I would like to see this added to IPfire to help others fix or atleast know about O’s limitations…

Hi,
OpenVPN on IPFire uses the tun interface (routed OSI layer 3), this how to needs a tap interface (bridged OSI layer 2).

Best,
