As far as the NAT configuration, it looks good. The only extra command you have is "ip nat pool 1 192.168.1.1 192.168.1.249 netmask 255.255.255.0" It is unnecessary. The rest of the NAT configuration will translate your server from 192.168.1.253 to 188.8.131.52 for SMTP (TCP 25) and HTTP (TCP 80). So external users on the internet can use 184.108.40.206 to access your server for that type of traffic. All other traffic from this server and your LAN will be translated to the IP address on the Dialer interface. If you have questions about the DSL part, I'll let others comment.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
