I have no Sparc experience, but I believe this should do the trick:

/usr/sbin/ipmasqadm portfw -a -P tcp -L <external ip address> 80 -R
<internal ip address> 80

Do same thing for port 443 if you need https.

Of course you'll need to allow http traffic through your firewall as
well, which I assume you probably already do, unless you never use the
Internet.
