Shou= ld=20 net.inet.ipsec.trans.cleardf be net.inet.ipsec.trans_cleardf, or are there plans for the trans sub-branch? As it might help people coming into ipsec in the future. Is it possible to = have a crisp (clear) description that distinguishes=20 net.inet.ipsec.trans.cleardf: "Clear do not fragment bit for outgoing trans= port mode packets." and net.inet.ipsec.dfbit=3DDo not fragment bit on encap. Suggestion net.inet.ipsec.dfbit=3D"Do not fragment bit on tunnel encap." ^ (I'd personally prefer net.inet.ipsec.tunnel_cleardf, and obsolete, in the future, ipsec.dfbit as it doesn't do as currently stated. Perhaps worth consideration?) --=20 You are receiving this mail because: You are the assignee for the bug.=
