You're absolutely correct, however your original post seems to have
taken many of us by surprise, causing some of us (at least me!) to
assume that you've changed the default method to allow. I'm obviously
misunderstanding, so I apologise for that, but I hope you can see the
reasoning behind my comments with what I knew at the time. :)
ipfw needs to be before networking or router discovery
fails for IPv6.
http://www.freebsd.org/cgi/query-pr.cgi?pr=conf/108589
as default any network connection will fail so long as you do not permit it
If rtsol fails or is called to early it is an rtsol problem and not an ipfw
problem I guess
named and ipfw before netif?
ip6fw is before networking. ipfw is supposed to be taking
over from ip6fw. ipfw and ip6wf should be started at a
similar time.
rtsol is approximately the equivalent to DHCP. The machine is
requesting a address from the network. It doesn't matter if
it is a router or a DHCP server that is suppling the address.
DHCP only works because it bypasses the firefall.
Mark,
Currently the order (with some non-networking items removed) is:
/etc/rc.d/ipfilter
/etc/rc.d/ipnat
/etc/rc.d/ipfs
/etc/rc.d/sppp
/etc/rc.d/auto_linklocal
/etc/rc.d/pccard
/etc/rc.d/netif
/etc/rc.d/ip6addrctl
/etc/rc.d/atm2
/etc/rc.d/pfsync
/etc/rc.d/pflog
/etc/rc.d/pf
/etc/rc.d/isdnd
/etc/rc.d/ppp
/etc/rc.d/routing
/etc/rc.d/ip6fw
/etc/rc.d/network_ipv6
/etc/rc.d/ipsec
/etc/rc.d/ipfw
/etc/rc.d/nsswitch
/etc/rc.d/mroute6d
/etc/rc.d/route6d
/etc/rc.d/mrouted
/etc/rc.d/routed
/etc/rc.d/NETWORKING
ipfilter starts very early in the "late" section of rcorder, it
requires mountcritlocal (the default early_late_divider) and has a
BEFORE: netif.
Currently ip6fw actually starts after routing (and therefore after
netif). Before we move it I think someone who knows more about how
rtsol works than I do should comment. AFAICT, network_ipv6 is going to
need routing up. If ip6fw's functionality is going to be subsumed into
ipfw, then changing ipfw to run before netif now, and nuking ip6fw
later is probably sufficient.
If it's reasonable to conclude that we want all the firewalls to start
before netif, I see two ways to accomplish that. One would be to have
netif REQUIRE ipfilter, pf, and ipfw. In some ways I think this is
cleaner, but netif already has a pretty long REQUIRE line. The other
way would be to add a new FIREWALLS placeholder for the REQUIREs I'm
suggesting above, and then have netif REQUIRE that.
If on the other hand, there is some reason NOT to start all the
firewalls before netif, then things get more complicated. :)
The attached patch changes the rcorder to the following:
/etc/rc.d/sppp
/etc/rc.d/ipfw
/etc/rc.d/pfsync
/etc/rc.d/pflog
/etc/rc.d/pf
/etc/rc.d/ipfilter
/etc/rc.d/ipnat
/etc/rc.d/ipfs
/etc/rc.d/auto_linklocal
/etc/rc.d/serial
/etc/rc.d/netif
/etc/rc.d/ip6addrctl
/etc/rc.d/atm2
/etc/rc.d/isdnd
/etc/rc.d/ppp
/etc/rc.d/routing
/etc/rc.d/ip6fw
/etc/rc.d/network_ipv6
/etc/rc.d/ipsec
/etc/rc.d/nsswitch
/etc/rc.d/mroute6d
/etc/rc.d/route6d
/etc/rc.d/mrouted
/etc/rc.d/routed
/etc/rc.d/NETWORKING
Thoughts?
