how to remote using iptables from outside
 

Hello all,

I need to access my linux box in my office from outside, for sure i will need to access ssh and mysql port...

I've look around the net but it seems making me confuse.. or maybe it because I use a diffrent equipment ???

We are using a wireless connection internet, our ip is 202.x.x.x

the router ip is 192.168.5.1

and my server is 192.168.5.2

I'm sure what I need is do something with Iptables PREROUTING.. but I couldn't make it so far..

I really need this thing working asap, and I don't have much time to surf around the net.

So please can anyone help me... please...

thx :newbie:

Your office router has to be set to forward ports 22 tcp and 3306 tcp from external ip to your office server.

Asssuming your router is a linux system

you will need rules like

sbin/iptables -t nat -A PREROUTING -p tcp -i eth0 -d xxx.xxx.xxx.xxx --dport 22 -j DNAT --to <localip>:22
sbin/iptables -t nat -A PREROUTING -p tcp -i eth0 -d xxx.xxx.xxx.xxx --dport 3306 -j DNAT --to <localip>:3306

/sbin/iptables -A FORWARD -i eth1 -o eth0 -d <localip> -j ACCEPT


edit /etc/sysctl.conf, set

net.ipv4.ip_forward = 1

and run

#/sbin/sysctl -p

wow.. that was quick... thanks a lot for your help.. I'll try it tommorrow.. first thing in the morning...

thanks again...
