NAT configuration on Dynamic IP

I have an ISDN router cisco 2503 and I have configured DDR to connect to my ISP using a dial-up account.  The ip address on the bri interface is negotiated during connection (dynamic IP).  I need access to some of the internal PC's in my LAN.   Anyone has any sample configuration for this issue.

Regards

Use the interface when specifying the outside address:

ip nat inside source static tcp 192.168.0.10 80 interface dialer1 80

Note that DDR means that the router will connect to the ISP only when it has "interesting" traffic queued to send.  So even if you can predict the address your router will have, you cannot really be sure when it will be connected to the Internet.

Essentially, then, if you "need access to some of the internal PC's in my LAN", then DDR is not a suitable Internet connection method.
