[Sherman Chan]

Hi Paul 

BTW I only see this on WAN interface eth0, but I see nothing on LAN
interface eth1

11:39:42.109197 9.8.7.6 > 1.2.3.4: ESP(spi=0x56fa544f,seq=0x34)
11:39:43.110076 1.2.3.4 > 9.8.7.6: ESP(spi=0xcbe4c4c8,seq=0x37) 

Thanks
Sherman

no no.

So you have a conn that works on 2.4.3 but not 2.4.4?
Did you try a userland 2.4.3 with klips 2.4.4 and/or a userland 2.4.4 and a
klips 2.4.3?

Another bug work around for 2.4.4 was to set fragicmp=no. But for 2.4.5.rcX
that should no longer be needed.
