>Environment:

	Nothing special. SKIP set up with SAFER for keys and
	traffic, MD5 for authentication and using tunnel mode.

>Description:

	SKIP appears to work perfectly (fetches remote host's
	certificate properly, generates packets understood by
	remote host) except that incoming proto 57 packets are
	always dropped, skiplog says:

	<date> : Warning: <host> (<IP>) failed authentication
	Its certificate/key id may be invalid


>How-To-Repeat:

	Set SKIP up with remote keys etc, ping remote host.
	Observe protocol 57 traffic with tcpdump, monitor
	skiplog and SKIP encription stats.

>Fix:
	
	Dunno. Playing with MTU on the SKIP-enabled port
	doesn't seem to help.
