is safe to ignore port 80??
IMHO, absolutely not...

if you are getting oversize reports like that, you can increase the size of your
oversize_dir_length setting in the http_inspect preprocessor section of your
snort.conf file... we use 750 here but you may need a larger or smaller value
depending on the traffic on your network...

thanks
i have removed 0.0.0.0 from home net
now how can i stop alerts from ip dst 0.0.0.0
