In general, you would do something like-
Go to Firewall, Virtual IPs. Add the outside IPs.
Setup outside to inside maps via Firewall, NAT, 1:1
Go to Firewall, Rules, WAN, and create rules to allow the traffic.
eg- TCP * * 1.0.0.124 80 * *
etc…
Although you could just use port-forwards instead of 1:1 NAT.
