try:
1. enable "syncookies" back.
2. disable "route cache.
3. disable Both "send redirect" And "send redirects", secure redirects, "source path", "allow fast path"(atleast temporally)
4. set "strict" RP filter.
5. reduce conntrack timeouts to more sane(2-3x, usually, atleast) values.
6. setup WIDE Bogon filtering(including LL and MC spaces on Wan interfaces).
7. setup port-scan detection on wan interfaces ASAP.

p.s.
sadly there is NO way to disable "loose" tracking in ROS as far as i knew :/ but its FTW in such cases :[
