Ok guys for some reason we are getting this few messages in our logs on the internal firewall. Could someone please explain them and maybe help me figure a way to correct them.
This first one is from our internal firewall and we just started getting it and im not sure why it fills up the logs and gets very annonying. ICMP packet dropped - Source:216.201.17.127, 3, WAN - Destination:216.201.17.7, 3, LAN - 'Dest Unreachable' - Rule 0 This second message also fills up the logs and is very annoying we get these route redirect messages from our firewall and it is coming from out cisco 7500 router which you see is the 209.143.12.X address. ICMP packet dropped - Source:209.143.12.1, 5, WAN - Destination:216.201.17.7, 5, LAN - 'Route Redirect' - Rule 0 We also have another firewall that is on the outside and it says that it is getting a smurf attack from our firewall which is 216.201.17.7 to the 216.201.17.127. I guess you guys could take these issues one at a time and try to maybe explain. I dont have a log message from the other firewall about the smurf attacks because i just deleted them all, but it gives you an idea.
