we are upgrading our FW (nokia ip530) to Cisco pix 515 with graphic PDM (3.0). Since I don't have any experience of Cisco firewalls I'd like to ask a couple of questions.
In Nokia IP530 if we wanted to permit IP traffic i.e from external (outside) host 10.20.30.40 to an internal (inside) host 10.30.40.50 all we had to do was make one rule permitting traffic from inside to outside and another rule to permit traffic from outside to inside.
Now with this PIX it seems that the configuration is not that simple...it seems like we have to define NAT also. Is it possible to permit the traffic without using NAT?
If NAT must be used how do we have to configure the PIX?
Thanks in advance
