| 13 | - conntrack helper not called for first packet (udp!) |
| 14 | - why is nat_helper's expect() function called for all helpers? |
| 15 | X full tcp window tracking incompatibility with nat helpers [HW] |
| 16 | - Hard lockup with ip_queue under heavy load (still valid ???) |
| 17 | - mangle table should use all five netfilter hooks [HW] |
| 18 | - merge EPRT / EPSV ftp stuff |
| Harald Welte | 61b1989 | 2001-04-24 00:02:33 +0000 | [diff] [blame^] | 19 | X runme error with IPv6 stuff! [HW] |
