Description jfm2 2001-02-07 09:06:30 EST
After selecting to configure IP through DHCP the user should not be 
allowed to use the 'strong' security option in the firewall step since 
this one will not let pass DHCP requests.  Another option would be to warn 
the user about this and in case he confirms then use stong settings except 
for DHCP.
Comment 1 Michael Fulbright 2001-02-07 11:25:55 EST
I believe DHCP is intended to be allowed through all class of firewalls offered.

Assigning to a developer.
Comment 2 Bill Nottingham 2001-02-07 13:03:03 EST
The idea is that if you have an interface configured via DHCP, the installer
silently selects to allow DHCP behind your back.

Did you use the graphical or text installer?
Comment 3 jfm2 2001-02-07 14:56:32 EST
No, because I am curious I selected strong security after selecting config
through DHCP.  As foreseen the network card just waited for a DHCP reply who
never arrived.   I then rebooted single user , deleted the rules from
/etc/sysctl/ipchains and this time it worked.  So when you tell it to reject
anything coming through eth0 it drops DHCP too.
Comment 4 Bill Nottingham 2001-02-07 15:13:11 EST
Um, maybe I misunderstood, but I still don't whether you used the graphical or
text installer.
Comment 5 jfm2 2001-02-08 08:07:54 EST
Iused the graphic installer
Comment 6 Glen Foster 2001-02-08 10:51:33 EST
We (Red Hat) should really try to resolve this before next release.
Comment 7 Bill Nottingham 2001-02-08 12:24:04 EST
Fixed in anaconda, should be in the next build; if any interface is selected
to use DHCP, DHCP will be automatically punched through the firewall.

verified fix in qa0217.1 test tree ...
