Hi Jacek, The error you mention may be caused because you have your external ip range included in your LAT. Please check your LAT table configurations. Hope that helps, Sonny Mulitalo -----Original Message----- From: Jacek [mailto:info@xxxxxxxxxxxx] Sent: Tuesday, 15 October 2002 7:34 p.m. To: [ISAserver.org Discussion List] Subject: [isalist] RE: Prblems with SPLI-DNS I made a split DNS. An external DNS zone is arwal.com.pl , and internal DNS zone is intranet.arwal.com.pl . I am using DHCP. I set option 15 in DHCP ( DNS server ) to intranet.arwal.com.pl . In event log I have an error : 14120 The ISA server cannot create packet filter for xxx.xxx.xxx.xxx . The resolution for this error is in KB article Q288396 . But it doesn't works. Sincerely; Jacek
