bcrelay

[Hellboy]

I am busy getting udp broadcast to work with a bridge and wireless network card.
For automatically adding routing entries i use parprouted. I enabled bcrelay for udp traffic, so i can use the internal dhcp server.

I start bc relay:

Code: Select all

bcrelay -d -i wlp4s0 -o br0

In /var/log/messages i see the following:

Code: Select all

ul  8 21:51:11 localhost bcrelay[1171]: UDP_BroadCast(sp=68,dp=67) from: br0 relayed to: wlp4s0
Jul  8 21:51:11 localhost bcrelay[1171]: UDP_BroadCast(sp=38876,dp=7437) from: wlp4s0 relayed to: br0

Jul  8 21:51:23 localhost bcrelay[1171]: UDP_BroadCast(sp=38876,dp=7437) from: wlp4s0 relayed to: br0
Jul  8 21:51:26 localhost bcrelay[1171]: UDP_BroadCast(sp=38876,dp=7437) from: wlp4s0 relayed to: br0
Jul  8 21:51:28 localhost bcrelay[1171]: UDP_BroadCast(sp=68,dp=67) from: br0 relayed to: wlp4s0
Jul  8 21:51:29 localhost bcrelay[1171]: UDP_BroadCast(sp=38876,dp=7437) from: wlp4s0 relayed to: br0

I disabled the firewalld.service, opened the required port, but no luck.

Anyone a idea?

The pre-release thread is readonly. I am no working with the final release of Centos.

I added forward rules for bcrelay for all network adresses, but the UDP broadcast cannot be forwarded.

Anyone else an idea?
