This option adds a `CHECKSUM' target, which can be used in the iptables mangle
- table.
+ table to work around buggy DHCP clients in virtualized environments.
- You can use this target to compute and fill in the checksum in
- a packet that lacks a checksum. This is particularly useful,
- if you need to work around old applications such as dhcp clients,
- that do not work well with checksum offloads, but don't want to disable
- checksum offload in your device.
+ Some old DHCP clients drop packets because they are not aware
+ that the checksum would normally be offloaded to hardware and
+ thus should be considered valid.
+ This target can be used to fill in the checksum using iptables
+ when such packets are sent via a virtual network device.
To compile it as a module, choose M here. If unsure, say N.
