Hi,

I assume that the .211 address belongs to another machine.  What is the IP
address of the Ethernet side of the router ?  Do you use NAT on the Cisco
router or masquirading on the SuSE box (gateway/dialup server)? 

What subnet mask are you using and what is the subnet mask that the ISP is
using to route to you? I assume with a 210.x.x.x address you would both be
using 255.255.255.0, but just check with the ISP. 

What happens if you set the default gateway on the .212 machine to the cisco
router's IP for the ethernet port ?

Let me know and I will try and assist.

Cheers
Schalk Klee

Hi Chris

Thanx for your thoughts.  I can ping out to anywhere, but I can't ping back
from 
anywhere to teh 212 machine. Traceroute to the x.x.211 machine works fine,
and 
that machine is on the inside of the router (cisco 801). But if I traceroute
to x.x.212 
it times out on the outside of the router (isp side). This suggests to me
that the ISP 
is not routing my complete ip range, but they say they are., 

What next?

TIA

Chris
