ERROR[init_mproxy4@332]: can't create igmp socket

[eduarmen]

Hi, I need to forward IGMPv3 messages from enp0s8 to enp0s9, my .conf is this:

igmp enable version 3 mld enable upstream enp0s8 downstream enp0s9

But I get the following error:

Do you have an idea why igmp socket can be created?

1, run it with sudo 2, replace

IMP_LOG_ERROR("can't create igmp socket\n");

to

perror("can't create igmp socket")

you will get more error message
