I run a small java program called jredirect for forwarding a port. The problem is after a while the process halts. I don't know why and there aren't a lot of options, such as logging. It's run like this: /usr/java/j2re1.4.2_03/bin/java -cp /usr/java/jredirect/jredirect.jar jredirect.Main --poolsize 50 host_ip:src_port-dst_ip:dst_port So to forward 443 to a nonstandard port you could do: /usr/java/j2re1.4.2_03/bin/java -cp /usr/java/jredirect/jredirect.jar jredirect.Main --poolsize 50 192.168.1.30:443-192.168.1.40:445 How could I set this up to respawn of the process goes away? AND How quickly does something respawn? I've also tried to get port forwarding working with iptables, figuring it would be more stable, but I could not get it to work. Even if I open iptables wide open it doesn't work for me. Here are the commands I've tried: /sbin/iptables -t nat -A PREROUTING -p tcp -d 192.168.1.30 --dport 443 -j DNAT --to 192.168.1.40:445 /sbin/iptables -A FORWARD -p tcp -d 192.168.1.30 --dport 443 -j ACCEPT The examples of forwarding I've seen usually include -i plus the interface, like -i eth0. I do not have this in there because the address I need it associated to is a virtual, so it's eth0:2 for example. After running the commands above I can run iptables -L and it looks ok. Any suggestions or recommendations are appreciated. Thanks, James
