>>i want to use static nat in pix firwall how i can refer to PC with ip 172.16.14.20 to use public IP 62.68.65.46 (the ip 172.16.14.20 is in vlan 14 )

nameif ethernet3 dmz security50
ip address dmz  62.68.65.54 <this ip subnet mask>

your pc lan card and pix interface should be in same vlan


>>and and i want to open SMTP port on pix firewall
>>and deny ssh to vlan 14


access-list inbound permit tcp any any eq 25
access-list inbound deny tcp any any eq 22
access-list inbound permit ip any any

access-group inbound in interface outside



>>and  eable telnet tocisco roter from outside

config terminal
line vty 0 4
login
password     <your password> for telnet

Another way is static nating which will map external to your internal ip.
