Now what is 100,000 entries? With the timeout aggressively set at 10 secs (heck, with 10 secs I sometimes cannot even get all the images on home.netscape.com) it's only 1000 SYNs/sec. How many hosts you want to protect with such a firewall? Dima Avi Freedman writes:
If someone can hose a firewall with an adaptive SYN timeout and a 100,000 or more-entry state storage structure for pending SYNs (not that any particular implementation does this that I know of or don't know of) then I *WANT* them to attack me.
Something that un-subtle should be eeasy to track back to the source.
