hi i was using my isa 2006 as the firewall & providing internet access last week. i then decided to replace the' isa' with a router for a week. ive since removed the router put back the 'isa'and after a few troubleshooting procedures/reboots, the isa 2006 can do the following:
- isa 2006/external nic: 192.168.0.3/255.255.255.0 - received from my netgear super box that is directly connected to the internet successfully
- isa2006/internal nic: 10.0.0.1/255.255.254.0
- master dc/ad/dns/dhcp: 10.0.0.10/23
- isa2006 - can ping the below internal & external nic:
10.0.0.10 - successful
192.168.0.3 & 192.168.0.1 (netgear super box/built-in lan) - successful
question 1. for some unknown reason my isa cannot now receive internet access although i have no eventviewer issues on either master dc or isa 2006 ?
note: i have added: the proxy details as could not remember if they were being used at the time of using a router while doing other testing!!
note: i have also shutdown and restarted both server numerous times but still same issue
note: ive also logged on master dc & ran to clear 'scavenge records & cleared cache & updated server files & restarted dns, but this has not made a difference!!!!!!!!!
note: i have noticed one thing as i am going to add 2 isa2006 later, hence the internal properties in firewall policy for dns is as below even though subnet masks are set as: 255.255.254.0 - uuuuuuuuuum
my firewall policy is in this order: (i have not completed exchange yet although added)
dns - 10.0.0.0 - 10.0.1.255 & 10.255.255.255 - 10.255.255.255
