Doubt regarding ICMP_UNREACH_NEEDFRAG processing for IPSec

[Reji Thomas]

Hi,

I dont see the freebsd ip stack processing ICMP_UNREACH_NEEDFRAG  where
protocol is ESP/AH. ( The ipsec4_common_ctlinput is not implemented). If
this is right, how is the  PMTU discovery done for ipsec traffic or is it
that freebsd is not doing that?.

Thanks
Reji
