conduit permit | deny protocol global_ip global_mask [operator port [port]] foreign_ip foreign_mask [operator port [port]]
static (high_interface,low_interface) global_ip local_ip netmask mask
Use the static command to establish the NAT relationship between the inside and outside interfaces
Then use the conduit comand to set up the protocol and services the static will use.
access lists could be used in place of using a conduit statement
It might look something like this
static (inside, outside) 1.1.1.1 192.168.1.1 netmask 255.255.255.255
conduit permit tcp host 1.1.1.1 eq 25 any
