What I'm trying to do is forward port 23 from my laptop to my t2000 server. I've looked around on how to do this but most of the info i found online is complicated and I'm barely learning all of this. So my laptop is connected via wifi to the internet (wlan0), port 23 is already forwarded to the laptop in my router settings. Now I need to forward 23 to my server. Can someone give me a simple solution?

Here's my setup:

Laptop connected to internet via wlan0 (192.168.0.101)
Laptop (eth0 set to 192.168.200.105)
T2000 (eth0 set to 192.168.200.100)

All I'm doing is taking port 23 from my laptop to my server. I'm running slackware by the way.

well there are plenty of examples knocking around: http://www.philchen.com/2011/06/21/h...sing-netfilter iptables What's not clear about this guide? No point starting from scratch when there are so many good resources already out there.

And don't think we don't know port 23 is telnet! Don't use telnet. It's evil. if this actually is telnet, I would actually suggest using ssh to reach the laptop and then running telnet from there, or using an ssh tunnel to the laptop and port forwarding port 23 from puTTY or whatever your client system is.

Thanks that ones a lot simpler. I would change -i eth0 to -i wlan0 though right? Yes its for telnet, and alright ill just use ssh

yes, the interface in question would be the inbound one, so wlan0 in your case.
