Can someone help explain how I can forward ports, such as 80, from a
public DHCP address, to an Internal LAN address?

Because my public IP changes often I'm not sure how I can NAT that to
an internal LAN ip such as 192.168.1.103 port 80.

Currently my router is setup like so to NAT outside:

ip nat inside source list 1 interface FastEthernet1 overload

But not sure how I can take the DHCP assigned IP/port to an internal
IP.

Thanks?

Thanks for quick reply, but...seems extendable is seen as invalid
input. Maybe IOS?

Thor(config)#ip nat inside source static tcp 192.168.1.103 80 int f1
80 ?
<cr>

Thor(config)#$de source static tcp 192.168.1.103 80 int f1 80
ext ?
% Unrecognized command
ip nat inside source static tcp 192.168.1.103 80 int f1 80 extendable

Not sure what's up, but under initial config I was able to enter the
line with extendable, however after finalizing my config that last arg
was no longer available, so appear that something in my config is
changing so that I can not use this line?

Would it be due to using DHCP or maybe my config to NAT outside for my
LAN?

It's odd that it was available at first then as I was ready to enter
the line after initial config that it was no longer available.

I'm beginning to think this syntax is not correct:

ip nat inside source static tcp 192.168.1.103 80 interface
FastEthernet1
80 extendable

Any other suggestions ?

Thanks.
