Port Forward
Problem
Port-forward firewall outside, port 5000 to inside IP 192.168.1.100, port 8080.
Solution
conf t
static (inside,outside) tcp interface 5000 192.168.1.100 8080 netmask 255.255.255.255 0 0
access-list outside_acl extended permit tcp any host $OUTSIDEIP eq 8080
exit
(Change $OUTSIDEIP appropriately.)
This pre-supposes that the acl outside-acl is the active ACL for the outside interface.
