Is anyone here good with ISA??? Having a bit of a nightmare at work and can't seem to get my head around why it is happening....
ISA sits between bolton lea microwave link and our network, just upgraded from 200 to 2006, been done the ISA course during the summer so know the ins and outs. Trying to get access to our exchange box from outside net... mail.harper-green.bolton.sch.uk (yeah check it, dont think the lea have set up outside dns right) thats not the point though, isa external ip = 10.10.11.200, 255,0,0,0 internal networks are 2 cards, 10.15.1.1 and 10.12.1.201 for net and admin domains, set up isa as lea have asked with exchange but not working, have a pc in the switch on external network which is set at 10.10.11.45 to see if i can see the isa from the lea network (we are the only school to break away and have our own isolated network) the ip dont work, cant ping the isa box even though rules are set up to allow it, can see in log ping go into isa but does nothing........... main reason am asking..... isa throws a fit in alerts and says its going to ignore spoof attacks from the 10 10- addresses on both the internal and external cards, ie why the ping packets are dropped by the isa...
anyone had a nightmare like this? googled the errors and tried suggested things, cleared ip table etc......
any ideas?
