Allow VNC access to inside PC from the internet?

I have a Cisco 837 just for home internet use. How can I allow VNC access (5800) or remote desktop (3389) from an external IP to my PC. Do I have to do port forwarding or something?

Attached is my config, I want to allow external IP 1.2.3.4 to my laptop on the VNC ports and remote desktop.

Thanks

You could try this , say local information is, Local IP: 192.168.2.100 , Global interface: dialer1

ip nat source static 192.168.2.100 interface dialer1

to permit any from outside to 192.168.2.100 on port 3389 rdp.

access-list 104 permit tcp any 192.168.2.100 0.0.0.255 eq 3389 log

int dialter1

ip access-group 104 in

or

same static nat.

access-list 104 permit tcp host 1.2.3.4 host 192.168.2.100 eq 3389 log

int dialter1

ip access-group 104 in

Thanks, the router gives out DHCP so I guess I would just give it a static ip like 192.168.2.101 as 192.168.2.100 is the router ip and add your rules?

Yes, also make sure when configuring static in the PC that it also have dns information as well so that it can get to outbound internet, do c:\ipconfig /all on the other machines and take note of dns information.
