get rid from icmpv6 type 135 (neighbor solicitation)

I have recently observed much more traffic between two computers in the same local network.

How can I get rid from this using ip6tables ?

I tried but it seems that did not worked to specify at the system level to use only ipv4 network (on both computers).

Can I deny the source and destination ipv6 address ? Or these icmpv6 are really usefull in that case how reduce the flood ?

Is that serious ? I wasn’t awared of an attack…

I’ll contact my ISP tomorrow…

I have to precise that none of my computers are affected, each ethernet interface “blocks the flood”.
It appears only in promisciutous mode… that is very annoying when you want to snif the packets of all the network with those icmpv6 flood messing up the whole stuff.
You can say I could filter but I never been able to apply more than one filter at a time (how to use AND or OR in filter bar ???) ^^
