Hello all,
I have PIX 515. The past two mornings I have found hosts on my network that have Windows messenger service pop-up ads (yes, advertisements) on them. These messages are coming from the internet. I know this because the IP address that they are sent to is among those used for NATing. What can I configure on the PIX to stop this, and does this mean that there's likely a huge hole in my firewall?
Any help or advice is greatly appreciated!
