Question : Problem: Cisco 801 - Simple Nat Configuration

I desperately need help please...

From the workstations on the lan with:

IP Addresses 10.1.x.x
Subnet Mask 255.255.0.0

we need to connect to BT router on tel no 01234 567890

they have assigned us IP Address 101.102.103.157 (IP address is example only) on subnet 255.255.255.252

We use ISDN to connect from Cisco801

Cisco is 10.1.2.5 on 255.255.0.0

Interfaces in router config are:

BRI0

Dialer1

Ethernet0

I really need a complete config file please with the complete NAT settings to route FTP traffic.

Many thanks

Roger Lightfoot
