Using both IP-VS and IPTables.

Dear lvs gurus,
I have a working linux virtual server (redhat 7.3, patched kernel 2.4.18
from kernel.org, ipvs 1.0.6 compiled as modules) that does load balancing
(LVS_NAT) to two web and ftp servers. I'm currently looking at closing up
some open ports on the lvs machine and would like to use an iptables based
firewall for that. I have a couple of questions that other people might
have wrestled with and maybe have resolved:
- Does an incoming packet get processed by the ip-vs system first or by the
iptable rules? If I drop packets to all ports in the iptables setup - do I
need to explicitly open the ports used for the lvs? Will I break anything by
adding iptable rules?
- Has anyone else used a iptables configuration script/gui to add
firewalling to their director successfully? All I really need is to close
all ports except for the load balanced ones, and to do some static forwards
(not via the lvs system).
