ip and port forwarding in Solaris 10
Hi; I have the following issue:
I have a Solaris server running an old applications which connects to an http server in other server at certain port. The thing is that the http server has changed its ip and port and the addres in the app is hard coded and touching the app by now is out of the question.
I'm looking for a way to tell the Solaris which runs the app, ok; everything that goes out to the old ip/port please forward to the new ip/port.
I've been doing some research and the closest case I found had this solution:
"Here is the final solution:
Add the following rule to /etc/ipf/ipfnat.conf
Code:
rdr dnet0 from 10.218.141.156/32 to 10.218.147.210/32 port = 1521 -> 10.218.146.230 port 1521 tcp

and execute
Code:
ipnat -CFf /etc/ipf/ipfnat.conf

"
This solution comes from the post:
https://www.unix.com/unix-advanced-ex...orwarding.html
I added the following rule to the ipnat.conf file:
Code:
root@f1m12 # ipnat -l
List of active MAP/Redirect filters:
rdr ce0 from any to 192.168.155.30/32 port = 8080 -> 172.20.40.22 port 8081 tcp/udp

Where the first ip/port are the old ones and the second are the new ones, but get no answer. If I telnet to the new ip/port I can connect to the httpserver, but if I telnet to the old ones I get no answer like if it was not making the forwarding.
Here's my solaris:
Code:
root@f1m12 # uname -a
SunOS f1m12 5.10 Generic_127111-11 sun4u sparc SUNW,Sun-Fire-V490
This is my ipf config:
root@f1m12 # ipfstat -io
empty list for ipfilter(out)
empty list for ipfilter(in)

What am I doing wrong????
Thanks in advance.
Regards.
Pablo.

snnewgroup

snnewgroup.v0.3.8(8)					      System Manager's Manual					      snnewgroup.v0.3.8(8)

NAME

       snnewgroup - create a new sn newsgroup

SYNOPSIS

       snnewgroup newsgroup [server] [port]

DESCRIPTION

       snnewgroup creates newsgroup assigning it an upstream NNTP server of server:port.  If port is not specified, defaults to 119.  If server is
       also not specified, newsgroup is created as a local group which is fed only by articles POSTed to it.

       You will need to be root or own /var/spool/sn in order to add new groups.

ENVIRONMENT VARIABLES

       SNROOT If this is set and is not empty, the value is used in place of /var/spool/sn, the default news spool directory.

FILES CREATED

       /var/spool/sn/newsgroup
	      Directory where articles will be stored.

       /var/spool/sn/newsgroup/.created
	      Empty file for the newsgroup creation time.

       /var/spool/sn/newsgroup/.serial
	      Where snget gets its idea of the new starting serial number for newsgroup on server server:port.	The value is initialized to 0.

       /var/spool/sn/newsgroup/.outgoing
	      If server is specified, is a symlink to  /var/spool/sn/.outgoing/server:port, which is a directory, created if it does  not  already
	      exist.  If server is not specified, no file /var/spool/sn/newsgroup/.outgoing will be created.  See also snsend.
