OK.  That's not too bad.

Now, first glance seems to suggest that one of my Linux machines
is ignoring these redirects.  Is this controlled by a sysctl or
something?

And what's the general deal with ICMP redirects?  Honour them
or ignore them?  Are they 'safe'?  Or safe enough for use in 
an internal network?
