You are correct in that FireWall-1 does not bundle a solution like that
provided by Qualix.
One solution is for the hosts behind Paris to have both Paris and London
defined as default routers. A Solaris 2.x workstation will use the first
available default router in its route table. If that router is not available,
then the timeout for a reply is exceeded and Solaris automatically moves onto
the next default route in the table.
Those host that can not operate this way will have to have their default route
changed or behind a gateway that is doing dynamic routing.
It is that gateway that would provide an ICMP redirect for the internal hosts
because it would learn that Paris went down and that London is still available.
jj>2] Can a M$-Windows 95 client with PC-SKIP connect to a SKIP-enabled FW-1
jj> (remotely or locally) with full SKIP compatibility ?
That is a good question.
I am getting ready next week to test the interoperability between 3.0 DES
and SunScreen SPF-100. After that we will test SunScreen EFS and then SKIP
for Solaris. Hopefully, I can provide a timely reply regarding PC-SKIP as
