Hi Friends,
I am having some doubt in PAT and NAT concept . in our office we are using one public ip address and 90 LAN address. all the LAN can access internet with the help of single public ip address. in this concept, Are we using PAT in our network or any type of NAT is using here? . if we are using PAT means weather I can configure Static PAT ie particular Wan port number to map to particular Lan port number with out lan ip address. kindy help me.

you can change the port number as it moves through for security to obscure it but you need to have the ip addresses or it wont know what to map too
This example shows the configuration for static PAT:
ip nat inside source static tcp 10.11.1.1 1 210.11.1.1 101 ip nat inside source static tcp 10.11.1.1 2 210.11.1.1 201 ip nat inside source static tcp 10.11.1.1 3 210.11.1.1 301 ip nat inside source static tcp 10.11.1.1 4 210.11.1.1 401 ip nat inside source static tcp 10.11.1.1 5 210.11.1.1 501 ip nat inside source static tcp 10.11.1.1 6 210.11.1.1 601 ip nat inside source static tcp 10.11.1.1 7 210.11.1.1 701 ip nat inside source static tcp 10.11.1.1 8 210.11.1.1 801 ip nat inside source static tcp 10.11.1.1 9 210.11.1.1 901 ip nat inside source static tcp 10.11.1.1 10 210.11.1.1 1001 ip nat inside source static tcp 10.11.1.1 11 210.11.1.1 1101 ip nat inside source static tcp 10.11.1.1 12 210.11.1.1 1201
