Hello! I have the problem that I can not access the dhcp server which is running on the firewall(yes I now). :-) I can send the configuration with email. The dhcp server listen on the internal interface, if I switch of the firewall all works fine. Remember, its iptables, it worked also with the ipchains based SuSEFirewall script.
