IPV6 UDP port 6343

[Andre Pedro]

hello Sergey,

No, I have not.. the reason I've set this number quite high is because I am
expecting a huge amount of packets destined to UDP port 6343.. so I was
just playing with numbers really.

What number would you recommend? Also, why does it work with ipv4?

thanks,

Andre Pedro
