Hi,

I've a BIND name server that every day has a icmp
redirect in it's logs.  I get one entry from the
same place every day. Could this be a hack attempt.
It's always directed at my secondary.

icmp redirect from 1.2.3.10: 1.2.3.22 => 1.2.3.22

Does this not indicate someone is trying to tell the name
server to use a special route to 1.2.3.22? Can this be
innocuous or is this definitely hostile behaviour? Should
I contact the remote ISP?

TIA, TW
