Once you encrypt you cannot compress, or else there is something
wrong with
your crypto, as I understand it. Thus PPP compression would
only act on
the PPP and IP header stuff.
Yes, you wouldn't get a very good compression factor at least.
No offense, Glen,
None taken!
but this question tends to indicate that you have missed
a big part of the compression discussion.
That answers one question; I'll shut up an d listen for awhile.
Perhaps it was just that I dropped in on the middle of the conversation,
but I was puzzled as to what compression had to do w/security.
Another reason given for IPsec compression is to get a packet to
fit into
an IP tunnel payload. The argument against this is that MTU
discovery
should handle this problem.
