Hi,

I'm sorry if the proceeding procedure is incorrect, however from the
documents I read, it seems like I am doing it properly, however it does
not work as desired.

I want to redirect all incoming tcp packets on port 5012 to 192.168.1.3
port 23

ipmasqadm Ver: 0.42

[root@nut /root]# ipmasqadm portfw -f
[root@nut /root]# ipmasqadm portfw -a -P tcp -L 127.0.0.1 5012 -R
192.168.1.4 23

[root@nut /root]# ipmasqadm portfw -l
prot localaddr rediraddr lport rport pcnt
pref
TCP localhost erp.nut.ml.org 5012 telnet
10 10
[root@nut /root]# telnet localhost 5012
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection refused
[root@nut /root]# telnet 192.168.1.4 23
Trying 192.168.1.4...
Connected to 192.168.1.4.
Escape character is '^]'.

Also, on another port forwarding note, two external udp relaying
programs i commonly used to redirect battlenet stuff to another machine
don't work anymore. I'm nto sure if the network/udp stuff was changed or
if this is a bug, heres some debug info from uredir (available @
sunsite, this worked fine under 2.0.36):

Jan 8 22:49:39 nut ./uredir[29843]: received 8 bytes from
206.165.111.251, port 6112

Jan 8 22:50:00 nut icmplog: destination unreachable from localhost
Jan 8 22:50:24 nut ./uredir[29843]: received 8 bytes from 24.1.239.222,
port 6112
Jan 8 22:50:24 nut icmplog: destination unreachable from eithan

Again, I apologize if this my error, and not a kernel problems. Thanks
for your time
