Re: Sun-4/110 NetBSD Diskless NFS Issue

[Samuel Furtaw <samfurtaw%gmail.com@localhost>]

The network boot ROM on the Sun-4 doesn't understand classless
networks and my 10.100 subnet is a /16 network - I added the 172.16/16
as part of the same VLAN & firewall zone, so they are essentially the
same subnet.

The ICMP redirect - I'm not sure. OpenWrt must have this as a default
behavior. The ICMP redirect does show up directly before
communications break down though, which I hadn't considered. I'm going
to run some tests with a different network setup.

Thanks.
Samuel
