No. You need at least PIX 5.1 software. You would also be wise to get your software upgraded any way to fix bugs/issues + also Cisco where offering a PIX software to DES PIX software licence upgrade, which would give you IPSec encryption + SSH + PDM (Gui tool with PIX 6.x software).
Given the age of software I would also imagine you'll need to update the flash of your unit (I've assumed its a PIX520 with 2Mb flash)
