I want to rule out the obvious, but is anything pluged into a port that is part of VLAN 1. If you do a show interface vlan 1 does it show the vlan interface up and the line protocol also being up.

I am presuming here that you don't have your own infrastructure behind this router and you just have some PC's?

If that is the case then you will need to either statically configure the IP settings on each PC or enable DHCP on the 877. You will also need to get name-resolution (DNS) working. You can either statically configure this on each workstation, add your ISP's DNS servers to the DHCP config on the router or get the router to negotiate them on the dialer interface and automatically pass them on to the DHCP scope it is configured for.

I think you can even get the router to act as a DNS server (proxy?), however I have never configured this.

To get the router to request the DNS server addresses on the dialer interface add the line 'ppp ipcp dns request accept' under the dialer interface. You then need to add the line 'import all' under the dhcp pool configuration (which you don't currently have).

Plus make sure the interfaces are actually Up, that the dialer interface has negotiated an IP address and that NAT translations are taking place.
