We use a small VPN based on l2tpns/ipsec-tools/freeradius
and we expect an increasing number of connection up to 15K.
I would really appreciate if someone could give me more details
about l2tpns clustering. (or even describe a real world example)
Does it work with ipsec-tools?
How many MBits/s, simultaneous sessions can be handled by l2tps
What is optimal number of network NIC (one or two) for master/slave.
Is there another method of network balancing? (i.e. ipvs)
Need to say, we are not going to use "throttling" and "gardening".
Thank you in advance,
