Reading your issue and reading you config - I would like to ask a question.....
Your LAN on the 877 facing the firewall has an IP of ip address X.X.17.170 255.255.255.252 so your firewall Outside IP address is ip address X.X.17.169 255.255.255.252
That's OK - but on your router.....
ip address negotiated
So you are getting a DHCP address, your firewall will have a default gateway of the router, the router has a default gateway of the ISP and the dialer0 IP address. So how does your ISP know how to route X.X.17.169 255.255.255.252 to your Dialer0 interface???
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
