You mixed up your internal with the external. Internet facing nic needs to be in the x.x.8.x subnet. Your internal nic has to be in a different subnet as do your lan connections. 'tis the season to be of good cheer. Wishing one and all happy times with family and friends.

Thanks for reply you mean both subnet should be defferent and what about the external nic card gateway address its may be the firewall address thanks

google is your friend. spend some time with your friend. http://www.isaserver.org/tutorials/...

first off change the dsl router to modem mode .. switch it to bridged (modem only) (loose the 10.10.x.x network. ISA internal ip - 192.168.10.25 External ip 192.168.8.25 Cisco pix Cisco external ip - Real IP address (from ISP) Cisco internal ip - 192.168.8.24 Right now you have dsl router "firewall",to cisco firewall,to isa firewall.
