I have my router set up to a class C address with 255.255.255.128 subnet. I have installed ISA and everything seems to be running well. I went to Gibson Research and I am running in full stealth mode (besides a few ports for games and ftp etc...) The problem stems from not being able to reach my router. I know my IP address for the router. I have another class c subnet for 3 home computers with a subnet of 255.255.255.128. I use the web interface to the router and I can not reach it to double check my external IP address from my adsl provider. I really suppose there is no major significance other than the fact that I would like to probe for any vulnerabilites from the outside of my firewall. I have set my alerts to email me and I have not had any alerts in a week. If this is the case great then I am sold on this product. Any suggestions would be great. ps.. I installed with the integrated option, and I could reach my router prior to installation. Angelwitch
