You said......I read on the the internet than this problem can be releated with the LAT. In the lat I setup the class up here and 217.156.38.255 - 217.156.38.255 That means you only have one ip address in the lat, it needs the complete range of ip addresses in the lat. Internal and external ip addresses on the isa server are on different subnets? Steve This E-Mail is confidential.
