Port forward DHCP WAN interface

magginoodles
Beginner
Beginner

Hi, I want to port forward externally from dynamic IP WAN (interface 0) to internal ip's ports to allow/restrict access to ports. So my home box, is IP 192.168.0.10, port 22, or another entry 192.168.0.10 3389 etc.

Here is a config I am using now

 

At the moment I can only get to 22 on interface 0 

 

Thanks for any help :)

Hi

 

If you want to do port forwarding, the command will look like: 

 

- for rdp:

ip nat inside source static tcp 192.168.0.10 3389 interface FastEthernet0 3389

 

- for ssh:

ip nat inside source static tcp 192.168.0.10 22 interface FastEthernet0 22

 

 


Thanks
Francesco
