Cannot access Internet from behind Cisco 887

I have just purchased an 887 ADSL Router to replace my ageing Netgear and have never setup one of the before. I have a small amount of experience with a PIX-501 firewall.

I followed the start up wizard and entered all the details as I understand them from my ISP. I have a static IP but I set the WAN address type as IP Negotiated as I do not know the IP address and on my old modem I had it set to DHCP and it worked ok.

My provider told me I was conencted but I could not browse. And using the built in interface to ping it timed out and got no responses.

Where should I be looking to rectify this issue?

% Password expiration warning.
-----------------------------------------------------------------------

Cisco Configuration Professional (Cisco CP) is installed on this device
and it provides the default username "cisco" for  one-time use. If you have
already used the username "cisco" to login to the router and your IOS image
supports the "one-time" user option, then this username has already expired.
You will not be able to login to the router with this username after you exit
this session.

It is strongly suggested that you create a new username with a privilege level
of 15 using the following command.

username <myuser> privilege 15 secret 0 <mypassword>

Replace <myuser> and <mypassword> with the username and password you
want to use.

Is your DNS dynamic? or static? I do not see any DNS entries. There are no "ip name-server 'address'"

DNS is static, I'm using my ISP's DNS. I realised that and have now input that. So I will accept your answer as the solution.

However my NAT isnt working correctly, some entries are working: IE: 80, 25, 443. But 5721 is not and the local IP is correct its functioning. I'm using canyouseeme.org to check.

Any thoughts there?
