Port Forwarding

How do I translate the following from RED Hat to Solaris in setting up port forwarding?  (What is the exact RED Hat to Solaris 10 translation?

edit /etc/sysconfig/iptables

## add prerouting for learn only (no httpd) operation
*nat
:PREROUTING ACCEPT [7:1068]
:POSTROUTING ACCEPT [8:480]
:OUTPUT ACCEPT [8:480]
:RH-Firewall-1-INPUT - [0:0]
-A PREROUTING -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 8081
-A PREROUTING -p tcp -m tcp --dport 443 -j REDIRECT --to-ports 8444
-A OUTPUT -p tcp -m tcp -o lo --dport 80 -j REDIRECT --to-ports 8081
-A OUTPUT -p tcp -m tcp -o lo --dport 443 -j REDIRECT --to-ports 8444
## end prerouting

# must be able to receive requests on ports 80 and 443
