Installing with dns and all other items default doesn't work

Selecting dns(dhcp) and all other items defaults at install
time results in a non-working network setup. In the
/etc/resolv.conf the name servers are correct but the
hostname and domain are incorrect (set to localhost localdomain)
All network scripts seem ok and the ether card module is
installed, networking comes up ok at boot time, but I can't
access the network (www) or ping anyone.
Steps to Reproduce:
1. install fisher
2. choose dhcp network setup
3. select all other items defaults
Actual Results: can not access network (www)
Expected Results: should have access to network (www)
failed same way on two separate computers with different
I've diagnosed the problem. The firewall is setup before the dhcp query for the
DNS nameservers. Therefore /etc/sysconfig/ipchains does not have any
permissions setup for the DNS namesevers. Therefore the firewall prohibits
(1) the host from resolving it's own DNS name from the nameservers
(2) the host from resolving any other DNS name from the nameservers.
I think you need to do the dhcp query before setting up the firewall permissions
during the boot.
To work around the problem I have to use the Text Mode Setup Utility "setup"
to (1) remove the firewall configuration, (2) configure the network, (3)
the firewall again (I don't want to play with the init scripts).
