How to select "Ethernet type"?

I am a little confused about the selection of 'ethernet type' when adding or editing rules. The RFC documentations mentioned in the help file is really too theoretical
Is there some general explanation and criteria?

 

Hi nuser

The main ethernet types are: all, IP, ARP, IPv4, IPv6 ...

Most of the time you have to set your rule to IP (IPv4+IPv6) or IPv4 ....
ARP is used for Address Resolution Protocol used locally to translate IP addr. <=> MAC Addr.

 

thanks, Climenole.
I have spent almost one day to search this forum and research.

the last one is for wireless?

If I select "other", what will happen?

What's the choice if I am using ADSL MODEM?

Sorry for so many questions.

 

Hi nuser

Don't be sorry for your "many" questions. That's correct to ask.

1- Last one: wireless: I guess so but I'm not sure...

2- Other: nothings except if you have other protocols used in your system...
Try it ! (and verify if I'm right or wrong...)

3- ADSL modem: this is related to an other level of the TCP-IP...
You have to choose the right network interface in the option tab of LNS...
