Re: [LUG] freeswan ipsec



Just re-read this section and had a few thoughts

Although each client can connect to the server connecting to each other 
(client-client) is difficult. Some of the protocols involved are 
non-routeable, i believe, so you will have to masqurade all the clients as 
the same private subnet and you don't want these sort of protocols flying 
around unencripted either.

You will be able to see everybody in the browselist (as the server knows where 
eveybody is) but communication between clients will attempt to go direct so 
you may need some "hairy" routing to create a virtual subnet. 

If you allow direct client-client access every client will need its own 
Certificate athority and evey client will need every other clients public 
certificate, instead of just one CA on the server and a certificate for each 
client. But the server aproach will double the bandwitdth usage / CPU as the 
packets must enter your gateway server, be decripted, be routed, be encripted 
and send to the other client!

Just some thoughts!

anyway more importantly links:-

look at http://vpn.ebootis.de/ for windows client and basic linux server setup 
info plus windows helper progs and look at http://www.freeswan.ca for 
superfreeswan / x509 patches for normal freeswan.
