iptables and vpnc
When I telnet in and start VPNC everything runs smooth. I'm not having trouble connecting.
Now on the page where the script is, it recommends that i add these rules to iptables:
iptables -A FORWARD -o tun0 -j ACCEPT iptables -A FORWARD -i tun0 -j ACCEPT iptables -t nat -A POSTROUTING -o tun0 -j MASQUERADE
I'm am a newb when it comes to iptables. I've been reading docs on it all day, and I still can't figure out the necessary rules to accomplish my aim.
If any one can shed some light on this, i'd appreciate it
You want to use the source and destination for this.
For example lets say 192.168.1.21 is one of the ip address you want to access the VPN;
iptables -A FORWARD -o tun0 -s 192.168.1.21 -j ACCEPT iptables -A FORWARD -i tun0 -d 192.168.1.21 -j ACCEPT
And forward in if the packet is going to 192.168.1.21
There are many ways you can write your rules. Take a look at this TUTORIAL that explains all the iptables switches.
The adventure of a life time.
