I personally haven't tried setting it up, but I think GRE tunnels may be
what you might try using.  Either IPSec inside GRE or GRE inside IPSec.

GRE tunnels (if I read it correctly) should support broadcasting.

following the steps at
http://www.jacco2.dds.nl/networking/win2000xp-freeswan.html, to get the
VPN up and running. using this I have a ppp tunnel between windows and
linux, which is inside a l2tp tunnel which is again encrypted by IPSec.
(the url gives the configuration in detail and I have followed it exactly)

(for a stock exchange, where the quots data comes as b'cast). Since the
windows is having an ip in the same network their is no reason why
B'cast should not work.

Base Article No. 253169 which says that B'cast is not supported in
Windows IPSec. Is this the case with Linux also. Is their any thing that
can be done to send B'cast also. Any help here will be much appriciated.
I am working though Xmas to get this working :(
