I'm 193.71.148.146. When I try to ping or traceroute 172.29.220.11, I
get "destination host unreachable". traceroute shows:

Tracing route to [172.29.220.11]
over a maximum of 30 hops:

1 40 ms 20 ms 20 ms 193.71.148.10
2 193.71.148.10 reports: Destination host unreachable.

When I go to our PM2 which is 193.71.148.10, it says:

trf-pm2> show route 172.29.220.0
Destination Mask Gateway Source Flag Met Interface
----------------- ---- -------------------- ------- ---- --- ---------

>From the 193.71.148.12 I can ping 172.29.220.11 without any problems,
and it reports:

The PM2 (trf-pm2) has the following filters on the ethernet interface:

Any ideas on what's going on?
