Thanks alot for the help

It will bend in the direction that it is already bent. If we extend your thigh bone out, we can see that, at rest, it bends forward:

Because of that, it will continue to bend forward with IK.

You can change the bend in either edit mode or pose mode to change the pre-IK bend:

Once I rotate the calf so that it bends correctly, shown left with IK disabled, the IK bends the right way, shown right with IK enabled.

We could change that in the rest pose, potentially, by moving the knee forward, but that’s not always a good idea. We could use bone constraints to create the pre-IK bend if we wanted instead of manually posing the bone-- constraints on an IK chain bone will always be evaluated before the IK.

so its just matter of moving the ankle abit forward in edit mode
and then its bend right …
