[Openswan Users] Different PFS setting but can connect success

[Peter McGill]

But really, why would you want to disable it, if your successfully connecting, since it increases security!

set pfs=no on both sides. this ensures that neither of the vpn server request pfs.

Hi, 
        Is there anybody knows how to disable this feature?, I means, do not use PFS feature if I disable it.

pfs

Whether Perfect Forward Secrecy of keys is desired on the connection's keying 
channel (with PFS, penetration of the key-exchange protocol does not 
compromise keys negotiated earlier); Since there is no reason to ever refuse 
PFS, Openswan will allow a connection defined with pfs=no to use PFS anyway. 
Acceptable values are yes (the default) and no.
