RE: DHCP from isp

Hi
 
Packet Filter is on and i tried several packet filters also a packet
filter with ANY for protocol and direction on BOTH and everything for
port 68 and 67 on tcp and udp but this doesn`t work at all.

        hi Bas
         
        Another solution which has came up on this board is to delete
the existing DHCP filter and recreate it. Is packet filtering turned on.

                        Enable the  DHCP filter, buy a book on ISA and
read it, explore www.isaserver.org.

                                Hi
                                
                                
                                We got an Isaserver running with two
nics one for the internal network
                                and one for the external network.
                                The external nic must use dhcp to obtain
an ip address else it does not
                                work with the ISP however ofcourse our
ip address is always the same
                                cause it is bound to the external nic
mac address by the ISP.
                                When we start the system everthink work
fine but after six ours the dhcp
                                lease has ended and the nic can`t obtain
a new ip address.
                                So we contacted the ISP and they said
that there was a discovery for an
                                dhcp server but never an acknownledge.
                                When we dissable the packet filter
everything worked fine we always can
                                obtain an new ip address but ofcourse
that is not what we wan`t.
                                Do i have to create an packet filter for
the external interface ? Cause
                                i did create some packet filters but all
with no succes.
                                Or do i always need a static ip address
?
                                
                                Please Help Me
