I have a 1601 router configured to accept ppp-chap calls.
It is configured with a default gateway and this should remain unchanged.
What is the most 'elegant' way to configure the dialer to make the ppp client follow a different default route without touching the routing table of the client?

I assume, when you mention "dialer" means the interface on a 1601 which terminate the incoming call.
Once the route is configured with a default route and once the default route is in the routing table, it will be followed if no specific route is matched with the packet to be routed.
So now other way to make the dialup client to follow any other default route. However you can use "Policy Based Routing" based on a source of a packet the packet will be routed. Pl. visit

Thank for your reply, I configured my router using your suggestions.
I noted however that policy routing, at least on my 12.0 ios, does not correctly support configurations via dialer-ip announced via proxy-arp on the eth interface.
I have than assigned a pool of addresses on the dialer interface not overlapping with the ethernet block of addresses.
For the people reading I paste a sample of the confiiguration that here is functioning bullet-proof:
[192.168.2.217 is a ppp client calling ip, 192.168.1.2 is the gateway associated to the clients, 192.168.1.1 is the primary gateway for the lan]
!
version 12.0
!
int dialer1
ip policy route-map tagthis
ip route-cache policy
!
route-map tagthis permit 10
match ip address 17
set ip default next-hop 192.168.1.2
!
access-list 17 permit 192.168.2.217
ip route 0.0.0.0 0.0.0.0 192.168.1.1
