I am trying to get it so when you telnet to my linux box with my static ip the linux server will forward the telnet session to my internal sco box with a internal IP.

I have read up on masqing(which works fine.) and IPchains which is working also. When I try to forward the ports i put in the command:
/usr/sbin/ipmasqadm portfw -a -P tcp 64.xxx.xxx.xxx 23 -R 192.168.50.5 23

Linux seems to accept the command because when I do a /usr/sbin/ipmasqadm portfw -l it shows what i am wanting it to do but it just doesn't work. When I telnet to the static ip it just sits there and doesn't do anything. Any one have any ideas to what i can do??
