Hi Isa enterprise edition isn`t a solutions for so i think we have to get another ISP which does not use DHCP. Does anybody know other newsgroups where I can post my problem ? Thx -----Original Message----- From: Joel Mansford [mailto:Joel.Mansford@xxxxxxxxxxxxxxx] Sent: Thursday, April 25, 2002 1:04 PM To: [ISAserver.org Discussion List] Subject: [isalist] RE: DHCP from isp http://www.ISAserver.org I had the same problem as yourself, one of the guys on this list forwarded me a script which I believe stopped the service, renewed the lease, and started the firewall service again. I tried this but my ISP issues four hour leases and stopping the service every four hours is far from ideal! Bizarrely, I found that upgrading to ISA enterprise edition (MSDN copy) fixed my problem, can't explain why but it did.

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 ?
