Ben, It is worth noting that none of the IPsec RFCs cite any of the IP-in-IP RFCs. This is not an accident. With IPsec, one is not performing IP-in-IP. Rather, one is performing IP-in-AH or IP-in-ESP. The IP-in-IP RFCs don't include IPsec within their scope. It was quite intentional that this was done. It is equally intentional that the IPsec RFCs haven't been citing the IP-in-IP RFCs. In effect, ESP tunnel mode uses the outer IP as a link-layer. Copying DF bit is not prohibited for IPsec tunneling, but neither is it required for IPsec tunneling. Ran rja@inet.org who wrote the relevant IPsec RFCs...
