PPTP or L2TP ?

[Theo Cabrerizo Diem <diem-debian-security@carpediem.sh>]

Hi,

I like to know what u think about VPNs using PPTP/L2TP protocols ...
I think freeswan is much better choise .. but I need to connect some
clients to my network .. and those clients doesn't use linux :( .. but I
do =) ....
So .. I have 2 choices =) PPTP (PopTop software) and L2TP (sorry .. have
some win98 boxes, so can't use freeswan with X.509 certificates) ...

So .. what u think ? ... L2TP support in linux seems to be still in
alpha stage ... :o/ ...

Is PPTP (with MS-CHAP 128 bits key <I think it's weak :/ .. isn't ? > )
better than L2TP (but in alpha stage) ? ...

Someone know other software (GPL/freeware) to do this ? ...
