Turn packet filtering back on. If you want to enable / disable pings to ISA for troubleshooting, create a packet filter that allows "ICMP ping request" inbound on the default external IP and leave it disabled until you need it. Disabling packet filtering just gives you an expensive, limited router.

A couple of weeks ago, I couldn't get into any sites, when I tried to ping my public ip, it's not working. I checked the logs in ISA and the reports say that some UDP and TCP sessions are being blocked. Disabling the packet filtering option solved the problem. But I don't want packet filtering option to be disabled permanently, what should I set in the packet filtering to be able to use the surfing, the only options installed right now are ICMP's and UDP's. Hope you can enlighten me with this. Thanks. ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: jim@xxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
