In trying to optimize some things, I recently ran a verbose traceroute
and found the following at the start of it:
----
1 199.190.67.1 (199.190.67.1) 36 bytes to 205.148.224.9 120.225 ms
36 bytes from 127.0.0.1 to 127.0.0.1: icmp type 3 (Dest Unreachable) code 3

Repeated for the first 2 hops (both thru my ISP). My setup is:
Internet <-> FRAD <-----+--> Rigel.orionsys.com (205.148.224.9)
205.148.224.1 |
+--> bbs.orionsys.com (205.148.224.2)
My ISP maintains my nameserver, and 199.190.67.1 is the first hop toward
the ISP...

What am I doing wrong? Everything works, but the odd unreachable loopback
message has me confused (not an unusual state). Is this degrading
performance?
