Port forwarding

Hi

I want to set up port forwarding from one network to another network. I already have this configured on the Linux box using iptables.

Code:
iptables -t nat -A PREROUTING -p tcp -i eth1 --dport 1521 -j DNAT --to 10.218.146.230
iptables -A FORWARD -p tcp -i eth1 -d 10.218.146.230 -j ACCEPT

Basically forwarding everything coming on eth1 for port 1521 to 10.218.146.230 (which is eth0).

I want to set up this configuration on solaris as well using ipfilters. I have tried following many documents on the net. But none seem to work. Please guide me as to the steps and configuration required to achieve the same on solaris or at least the equivalent commands.

PS: I am not that fluent in Solaris as in Linux. Nor have I worked with ipfilters before - always worked with iptables.

NAME
iptables-xml -- Convert iptables-save format to XML SYNOPSIS
iptables-xml [-c] [-v] DESCRIPTION
iptables-xml is used to convert the output of iptables-save into an easily manipulatable XML format to STDOUT. Use I/O-redirection pro- vided by your shell to write to a file. -c, --combine combine consecutive rules with the same matches but different targets. iptables does not currently support more than one target per match, so this simulates that by collecting the targets from consecutive iptables rules into one action tag, but only when the rule matches are identical. Terminating actions like RETURN, DROP, ACCEPT and QUEUE are not combined with subsequent targets. -v, --verbose Output xml comments containing the iptables line from which the XML is derived iptables-xml does a mechanistic conversion to a very expressive xml format; the only semantic considerations are for -g and -j targets in order to discriminate between <call> <goto> and <nane-of-target> as it helps xml processing scripts if they can tell the difference between a target like SNAT and another chain. Some sample output is: <iptables-rules> <table name="mangle"> <chain name="PREROUTING" policy="ACCEPT" packet-count="63436" byte-count="7137573"> <rule> <conditions> <match> <p>tcp</p> </match> <tcp> <sport>8443</sport> </tcp> </conditions> <actions> <call> <check_ip/> </call> <ACCEPT/> </actions> </rule> </chain> </table> </iptables-rules> Conversion from XML to iptables-save format may be done using the iptables.xslt script and xsltproc, or a custom program using libxsltproc or similar; in this fashion: xsltproc iptables.xslt my-iptables.xml | iptables-restore BUGS
