Hi,
This may be not an appropriate question to ask. Because may be OpenVPN is not
the right tool for transmitting viedo/radio data accross the Internet secure.
What is the right solution for it apart from using IPSec VPN? What will be
the performance issue if I use OpenVPN to do video/radio data tranmission
between sites?
I'd say OpenVPN is exacly the right tool for securing such a transmission.
If you got a good enough connection to transmit audio/video without
encryption, it should do fine with encryption to. A UDP based transmission
is especially well suited for this, as you want to keep the latency as low
as possible, and usually just want the stream to continue flowing even if
there are lost packets.
However, if the application creates UDP packets near MTU size, you might
get worse performance as these will have to be internally fragmented if
PMTU is not working correctly. (mssfix does not work on UDP)
