This won't improve your performance.
Only the forward or input chain can actually block packets. Mangle is like a paint sprayer - it can mark packets and change some interesting values on them, but it doesn't do any discarding.
Even if it did, this would not improve the performance, because the same basic actions must be taken: receive packet, identify it as a fragment, discard it. Routing table lookups are a very very very fast operation and don't take much CPU, especially when a destination is cached.
Okay! Enable IP Fragment option in "Prerouting" chain to mark fragmented packet but its not matching any single packet. If i disable check mark "IP fragment" it start matching packet..
I am sending "IP Fragmented" packet using following command to test,
-x option will set "MF" bit in packet. I have tired other option ot like -f and -g but its not matching anyone. I think its different purpose for IP fragment.
