ICMP is just another IP Protocol, routing is done at the IP layer.

This means that yes, you can route ICMP, to do this you would probably need
a router and at least another subnet (192.168.0.0/24 and 192.168.1.0/24
would do) and then you could setup a box with at least two interfaces and
configure forwarding and route your packets across the box between the two
subnets - you would then be routing ICMP.

The box in question can be pretty much anything as most OS's these days
will do routing of some shape or form or - if you are feeling rich you
could purchase a real router to do this job.

for kicks you can even put in place access lists so you can *only* route
ICMP and deny all other types of IP traffic.

Routing however is not really DSL related, there are other lists that this
question would be better sent to..
