[Openswan Users] L2TP/IPsec scalability

Hi all,

I'm looking into L2TP/IPsec remote access solutions using Openswan.  I've
got a working setup using xl2tpd 1.1.06 and Openswan 2.4.7.  I noticed a
comment in Section 13 of Jacco's L2TP/IPsec VPN guide that stated:

"It seems to me that l2tpd is great to get started and easy to use for small
setups. However, for a serious deployment with a considerable number of
clients, you will probably want to use one of the other L2TP servers:
rp-l2tp, l2tpns or possibly OpenL2TP."


Does anyone have experience running the xl2tpd fork in a production
environment with greater than 500 users and 100 concurrent sessions?  Or, if
you are using another L2TP server can you share your experiences.  I'll send
out a summary of whatever responses I receive.

Jacco, can you shed some more light around this comment and what type of
scalability issues that users might expect to experience?
