How?
I am not sure I understand the question.
The same way you configure iptables on non-oVirt-hosts machines.
If you mean "How to imitate the way the engine does this during
host deploy", then I don't know - you can check engine sources
for that. I am guessing that you can get the values of IPTablesConfig
and IPTablesConfigSiteCustom with engine-config, replace inside the
latter "@CUSTOM_RULES@" with the contents of the former, then copy
the result to the host and load it with iptables-restore (and/or
copy to /etc/sysconfig/iptables and restart iptables service).
