Hi, has anyone tried to get hipl to work on a device such as ASUS WL500W with OpenWRT kamikaze 8.09, kernel 2.6.28.8? As I have tried in recent days, it doesn't work at all. Although HIP I1, R1, I2, R2 packets are successfully exchanged, following data packets are received not as ESP packets, but UDP packets to the port 50500. When hipl receives a data packet, it complains with an error "HIP message is of zero length. Dropping.", libinet6/message.c:54, which means no packet data has been received. On my OpenWRT router, necessary kernel modules are already loaded: xfrm4_mode_beet, xfrm6_mode_beet, esp4, esp6, etc. I'm still trying to get it tested with other ways, but has any of you experienced such a case? Any kind of tips are also welcome. Cheers, Dongsu
