I have Cisco PIX (525) Firewall Version 6.3(5) with two interfaces.
For testing purpose,One Pc is directly connected to each interface.
From Pix i can ping both Pcs.
But cannot ping
inside interface of pix and pc(A) from pc(B) attached to outside interface.
outside interface of pix and Pc(B) from Pc(A) attached to inside interface.
PC A:
ip: 10.1.0.2
Gateway:10.1.0.1
PC B:
ip: 172.16.1.2
Gateway:172.16.1.1
PIX Configuration:
PIX Version 6.3(5)
interface ethernet0 auto
interface ethernet1 auto
nameif ethernet0 outside security0
nameif ethernet1 inside security100
access-list ping_acl permit icmp any any
access-list acl_out permit icmp any any
ip address outside 172.16.1.1 255.255.0.0
ip address inside 10.1.0.1 255.255.0.0
access-group ping_acl in interface outside
access-group ping_acl in interface inside
Now help is required for complete the configuration.
Also required Configuration Labs for testing the PIX.
Thanks in advance.

Hello Muhammed,
fixup protocol icmp
static (inside,outside) 10.1.0.0 10.1.0.0 netmask 255.255.0.0
static (outside,inside) 172.16.0.0 172.16.0.0 netmask 255.255.0.0
Or,
fixup protocol icmp
access-list inside_nat0_outbound permit ip 10.1.0.0 255.255.0.0 172.16.0.0 255.255.0.0
nat (inside) 0 access-list inside_nat0_outbound
