Did you also specify ike= ?
And aggrmode=yes?

can you try either 2.3.1 or 2.2.0, if this is a 2.3.0?

Yes, use pfs=yes and pfsgroup=modp1024

Remember, wit haggressive mode, you have to specify *exactly* what you
need. It does not allow for various proposals to be decided upon. If
possible, change aggressive mode to main mode on the netscreen to make
life a lot easier.
