Re: ICMP messages
Suppose say I want all packets going from host A to host B
encrypted/authenticated and an error occurs. The ICMP packet that I se
nd
back will also be encrypted or authenticated and hence one will not be
able
to understand the ICMP messages as either an SPI is incorrect or the k
eys
are incorrect.
Now, do we say that ICMP messages are not encrypted? In that case we c
annot
say that all packets going from host A to host B are to be encrypted?
Thanks,

Worse yet, if an intermediate route generates the ICMP bounce, there
won't be enough information in the returned portion of the header to
tie it to a particular socket.
